Problem Statement: If the case-fixed value for an attribute is changed in the DataModel, how to apply the modification in an existing Workspace. | Solution: TheSolution to this problem is to specify the parameter migratecases=true in the Workspace configuration file or in the library configuration file. This parameter is only needed when the value of the case fixed flag has been changed for attributes in the data model and these attributes have been used in an existing project. Once the data has been migrated the parameter can be removed from the configuration file. The parameter is not needed for a new project or a project where all the attributes have been migrated. The easiest way to migrate all the attributes is to run an integrity check using the procedure below:
1 You change the case fixed flag for some attributes that have data in the new project
2 Set the parameter migratecases=true parameter in the configuration file and reload the server
3 Run an integrity check using the line <%@DataService=<Kernel>::CheckIntegrity%> in the Query Editor of the Aspen Zyqad Explorer tool.
4 Check that the values have been migrated correctly using the Explorer or a datasheet.
5 Remove the parameter from the configuration and restart the Workspace.
The main reason you do not want the flag set all the time is that it may decrease the performance of the server on the workspace.

Problem Statement: Aspen DMCplus and Aspen SmartStep have been merged into Aspen DMCplus starting in version 2006.5 | Solution: In version 2006.5, theAspen DMCplus andAspen SmartStep applications were combined in the single application Aspen DMCplus.
Aspen SmartStep Simulate and SmartStep Desktop are no longer used because Aspen DMCplus Simulate and Aspen DMCplus Desktop are used instead.
The SmartStep application is activated by setting SMSTENB, SmartStep Enable. When this parameter is set, it activates the Aspen SmartStep parameters for modification. When the Aspen SmartStep tester is turned on, a license key is obtained SLM_SmartStep_Tester, which is the Aspen Smartstep online application. SLM_SmartStep_Advanced is for the Advanced / Multi-test functionality of Aspen SmartStep.
As a result of this change, the combination of these two applications inAspen DMCplus, the following features are NOT found in the license key
- SLM_SmartStep_Simulate
- SLM_SmartStp_Dsktp
No functionality will be lost, not having license keys for Aspen SmartStep Desktop and Aspen SmartStep Simulate, in fact, they will not be installed, instead Aspen DMCplus Desktop Tools and Aspen DMCplus Simulate are used. Also, the smartstep_viewsrv.exe will also no longer be running, as the Aspen SmartStep information for the Production Control Web Server is now provided through the dmcp_viewsrv.exe process.
You can find additional information regarding SmartStep in the DMCplus online help. From the Start Menu, Start / Programs / AspenTech / Aspen Manufacturing Suite / DMCplus Desktop / DMCplus Help.

Problem Statement: Is there an Aspen SQLplus query that will search the the source files for records defined by compquerydef for a tag name or a string? | Solution: The query attached to thisSolution searches the source files for records defined by compquerydef for a tag name or a string. The query assumes the source files are located in C:\ProgramData\AspenTech\InfoPlus.21\db21\group200\sql\; however, you can point to a different location by modifying the macro sqlfileslocation.Â
After prompting for a tag name, the query uses the system command to get a directory listing of all the files in the Aspen SQLplus query source folder and then selects files from that list based on the queries defined by compquerydef. The query then searches each line of the compquerydef source files looking for the tag name using the POSITION function. When the query finds the tag name, the query prints the compquerydef record name with the line numbers containing the tag name.

Problem Statement: Do APC online applications require constant contact with the license server? | Solution: The APC applications checkout a license the first time it runs. The application checks for connectivity to the license server each time it run, after that. It attempts to acquire a license every 4 hours. If it cannot acquire a valid license, it begins a 10 day countdown. The countdown messages are visible on the Production Control Web Server and in the .eng file and appear every 4 hours. This allows for 10 days to correct any connectivity issues. When the issue is resolved, and a valid license acquired, the countdown timer is reset to 10 days.

Problem Statement: How to transfer more attribute with the Object Mapper | Solution: The Object Mapper is used to transfer data between UO object from a simulation and equipment object. The transfer is controlled with classview defined in the ClassStore. The name of these classviews starts by ObjectMapper.
It is possible to transfer additional variable by adding new attribute in an ObjectMapper classview.
Each ObjectMapper class view attribute needs to be linked to two composite view attributes. The first one is the UO (Unit of Operation) attribute and the other is the equipment or stream attribute. You can alternate between these two links by doing a right-mouse click on the classview object and select Show Links for Alternate class.
In 2006, the Object Mapper has been incorporated in the Simulation Importer interface. However, the interface is still using the ObjectMapper classviews.

Problem Statement: During use of Aspen Zyqad any potential legacy problems with the database can cause disruption to later use of aspects of older databases or packages (Explorer or Graphical). This may mean that subsequently a diagram may not open or a package will not load. The specific cause associated with this problem were fixed in 2004.0.4. However, databases that may have incurred the problem previously can be checked by performing what is known as an Integrity Check. This checks that all object relationships remain properly formed in the database.
If you have never used graphical packages you are unlikely to have encountered this problem.
This article explains how to carry out an integrity check.
If a problem is found please contact your support representative who will refer the problem for repair. | Solution: The best Integrity Check procedure is built into 2004.0.5 (2004.0 updated with Cumulative Patch 5 (CP5))
Using the database you want to check (whether this uses Oracle, SQL Server or Access) open the Aspen Zyqad Explorer and connect to the workspace. Open the Query Editor from the View menu.
Type the following into the upper text entry part of the Query Editor (yellow background). Be careful to use the same lower and upper case characters (paste does not operate in this dialog):
<%@DataService=<Kernel>::CheckIntegrity%>
Click submit after which a spinning dial appears showing the query is operating and the Query Editor is waiting for a response.
After some time (a small database will take several seconds and large database several minutes), the response will appear in the lower text output window (blue background):
No object integrity errors detected
In which case all is well. If a problem is detected by the query, consult your support representative. You are advised to repeat the process for any projects that your workspace contains.
Older packages may preserve an integrity problem if they were exported from an older database which itself had an integrity problem. Using such a package later by importing into a good database, even after CP4, will reintroduce the problem. These packages should be checked out.
To check older or suspect packages, import them into a clean empty database if possible. This can be done with Access avoiding the need to use Oracle for example. Once imported, run the integrity check on the newly populated database. If this comes up clean the package is OK. Repeat this process for any older suspect packages. If a problem does occur, and you are unable to regenerate the package please contact your support representative who will arrange for your package to be repaired. If a package has a problem, this indicates that its source database also carries the same problem and needs checking and referral for repair. You should not regenerate a package from the same database unless it has been checked out and repaired if necessary.
Note: During the development of this built-in procedure, we had available an Integrity Check rule. This built-in procedure replaces these rules. If you are in the possession of one of these rules please use the built-in procedure with Aspen Zyqad 2004.0.5 instead unless advised by your support representative. The built in procedure has several refinements and is more accurate than these earlier rules.

Problem Statement: DEPW becomes different from DEP when the dependent variable is in out of serivce | Solution: This is expected behavior. DEPW is a value that sent to the engine after passing validation and calcs. It handles things differently depending on what is occurring with the variable. If the variable is out of service, then DEPW is typically set to some safe value so as not to hit any constraints (internally, the engine also adjusts limits to avoid out of service variables from affecting the control problem). So, DEPW is not something to be used for anything outside the controller engine. If you want to see what the transformed value of a variable is, you can use DEPA and VINDA.

Problem Statement: How can I display the last day of the month for reports? | Solution: Download the function LAST_DAY attached to thisSolution and use the SQLplus query writer to save the function as a procedure in InfoPlus.21.
Given an InfoPlus.21 timestamp, the function returns the last day of the month indicated in the timestamp argument as a character string using the date format specified for the Aspen InfoPlus.21 database.
This function uses the Aspen SQLplus function date_format to determine the date format of the InfoPlus.21 server, the function subtract_months to add one month to the timestamp passed into the function, and cast (timestamp as char) to round the result returned by subtract_months back to the first day of the month. Finally the function subtracts 24 hours to determine the last day of the month.
The Aspen SQLplus help files describe the functions date_format, subtract_months, and cast(timestamp as char).
For example:
write Last_Day('20-DEC-11');
returns
31-DEC-11

Problem Statement: While executing an Aspen SQLplus query inserting data into an Aspen InfoPlus.21 (IP.21) database, you might receive the error message: Error writing to <tagname>: Invalid key timestamp at line <x> . How to overcome it?
Example query: INSERT INTO ATCAI(IP_TREND_VALUE, IP_TREND_TIME) VALUES (4.5, '03-JAN-02 10:00:33');
Everything looks normal (the timestamp, the syntax, etc), but yet you are getting the above error. | Solution: There are three possibilities that can generate this error when executing this kind of SQLplus query:
1. You are attempting to update history for data that is older than your IP.21 repository's Past Time parameter.
The Past Time parameter sets the limit on how far back in time history can be inserted or updated. If the timestamp in your query places the data outside the past time parameter, increase the value of this parameter so that the data of interest lies within the covered dates. For example, if you want to insert data that is 30 days old, then you need to change the Past Time parameter to 720 hours instead of 24 hours. Finally, restart IP.21 for the new setting to take effect and rerun the query.
To configure the Past Time parameter for a given repository (eg. TSK_DHIS): go to the IP.21 Administrator => select the server name => select Historian => select the repository name => right click => select Properties => go to the Repository tab => in the Time frame you will see the Past and Future fields.
2. The record was not created at the time you are trying to enter. In other words, you cannot insert data into a record before its creation date. If you need to change the creation date of the record to allow for population of data, then use XOLDESTOK: see Knowledge BaseSolution 103040 for more details.
http://support.aspentech.com/webteamasp/KB.asp?ID=103040
Example: You have recently created a record on February 15, 2002. You are now trying to insert data into history repeat area for this record with the date and time of '03-JAN-02 10:00:33'.
3. The filesets do not go back that far in time. You will have to restore old filesets for that time range in order to insert data into them.

Problem Statement: How can I trap errors produced by a query and write error information to a log file? | Solution: A BEGIN / EXCEPTION /END block catches run-time errors during query execution providing a way to take corrective actions without the query aborting. If an error occurs in the code between the BEGIN and EXCEPTION statements, instead of exiting, Aspen SQLplus transfers execution to the statements located between the EXCEPTION and END statements. Several Aspen SQLplus functions capture information about the error. See the topic Error Functions in the Aspen SQLplus help file. You can write this information to a logging file in the exception block as follows:
BEGIN
--Main query code

Problem Statement: How can I check CIM-IO Get Records status using SQLplus? | Solution: Get Records are defined by IoGetDef, therefore querying this record will give you the status of your Get Records.
In order to have a quick overview it might be better to select just the following:
SELECT NAME,IO_RECORD_PROCESSING,IO_LAST_STATUS,IO_LAST_STATUS_DESC,IO_LAST_UPDATE
FROM iOGetDef
Otherwise SELECT * to get all details.
If you need to dump the results into a log file, use SET OUTPUT.
If you need to limit the query to few similar Get Records, the WHERE clause can be used.
SET OUTPUT = 'C:\IO_STATUS.log';
SELECT NAME,IO_RECORD_PROCESSING,IO_LAST_STATUS,IO_LAST_STATUS_DESC,IO_LAST_UPDATE
FROM iOGetDef
WHERE name like 'get%';

Problem Statement: When Performing a Query on a remote database using the 'ODBC OAM' the error message
'Complex Remote Update Or Delete Requires Row Identification Field'
is received. This knowledge base article describes how to work around this error message. | Solution: This error message indicates that the ODBC OAM module is trying to perform a generic ODBC query which, although syntactically correct, fails. The work around for this is to configure the ODBC link to use database specific syntax instead of generic ODBC. A list of databases is contained in the text file '%SETCIM%\sql\databases.dat'. Moreover, this file can be modified to accommodate new database definitions if required.
To change the ODBC OAM from using generic ODBC syntax and use database specific syntax, the ODBC link contained in the file %SETCIM%\sql\links.dat' requires the second parameter on the link to be manually modified.
Example:
To change the alias 'ORA' from using generic ODBC to Oracle the following line in '%SETCIM%\sql\links.dat' requires changing.
From:
ORA,odbc,odbc,OracleDSN
To:
ORA,oracle,odbc,OracleDSN

Problem Statement: When performing a remote UPDATE or DELETE query for MSSQL, the error: Complex remote UPDATE or DELETE requires row identification field at line xx is received. | Solution: If you are at version 4.0, the error message might be due to a bug that is corrected in Service Pack 1. Upgrade to version 4.0.1
If you are not at version 4.0 and are receiving the error message, implement a workaround for connecting to MS SQL Server. Two syntax workarounds are available:
use local variables ( in some cases), or
incorporate the Execute statement.
***** Example using local variables ***** Original:
UPDATE PS.PlantSchedule.dbo.Railcars SET
RStatus=2,
StatusDate=CURRENT_TIMESTAMP,
WHERE
CarNo=LastCar;
Changes to lines 3 and 5 result in the following error-free query:
UPDATE PS.PlantSchedule.dbo.Railcars SET
RStatus=2,
StatusDate=''30-jun-2001 00:00:01
WHERE
CarNo=local.LastCar;
*****
Example using the EXECUTE command *****
Original
Delete from abcsql1.mds.dbo.u_acomplex;

Problem Statement: How can I execute a QueryDef on a remote InfoPlus.21 server? | Solution: A way of executing a remote query would be to store it as QueryDef and not ProcedureDef. The reason for doing this is that QueryDef record can be activated on a Change Of State.
On InfoPlus.21 the field that activates the query can be updated and used as trigger for the query.
See example below:
A QueryDef record is stored on IP.21 #2. In order to trigger this record to run the query on IP.21 #2 from IP.21 #1 you will need to update the record that the QueryDef is monitoring.
That would be on #WAIT_FOR_COS_FIELDS.
So you would have on your IP.21 #2 a Trigger record that you would update from your IP.21 #1 via SQLplus, or any other way you might want to activate it.
In the WAIT_FOR_COS_FIELD you would specify TRIGGER IP_INPUT_VALUE
As soon as IP_INPUT_VALUE changes, the QueryDef record is activated.

Problem Statement: The CIM-IO documentation states how to start the Store and Forward (S&F) processes on Windows NT by opening a command window and executing the necessary commands. The S&F processes are stopped by closing the command window.
This | Solution: discusses how to start and stop these S&F processes through the use of an NT service. The processes belonging to an NT service persist or stay running over different NT logins. The processes run in the background - not via a command window.Solution
With the installation of CIM-IO on the NT platform, a service, CIM-IO Manager, is installed and found in the Control Panel > Services. When this service is started, a batch file called cimio_autostart.bat is run. This batch file is found in the C:\aspentech\infoplus.21\db21\commands or %CIMIOCOM% directory. This file needs to be edited to include the commands necessary to start the S&F processes. Open this file in Notepad and add this line:
%CIMIOCOM%\cimio_sf_start < servicename >
The cimio_sf_start is a batch file located in the %CIMIOCOM% directory that requires the DLGP service name to be passed as a parameter. Now when the CIM-IO Manager service is started, the cimio_sf_scanner, cimio_sf_store, and cimio_sf_forward processes are started and can be seen running in the NT Task Manager.
When the CIM-IO Manager service is stopped, a batch file called cimio_autostop.bat is run. This batch file is located in the same directory as the cimio_autostart.bat. This file, also, needs to be edited but to include the commands necessary to stop the S&F processes. Open this file in Notepad and add this line:
%CIMIOCODE%\cimio_sf_shutdown /S= < servicename >
(or /D= < devicename > )
The cimio_sf_shutdown is an executable found in the %CIMIOCODE% directory that requires a /S parameter of the DLGP service name OR the /D parameter of the logical device name to be passed. Now when the CIM-IO Manager service is stopped, the cimio_sf_scanner, cimio_sf_store, and cimio_sf_forward processes are stopped and will no longer be seen running in the NT Task Manager.
The CIM-IO Manager service can be set to start automatically when the NT box is booted. Or, it can be set to manual where the service can be started upon demand.

04-JAN-05 12:41:19.8 | Solution: In Query 1 the ORDER BY is executed on the local system and sorts the data returned from the remote system. The default setting for an ODBC data source is to return timestamp data as character data type (to preserve the InfoPlus.21 formatting). So, the ORDER BY in the first query sorts the data by character (alphabetic) order rather than timestamp ORDER.
Consider the same query, written to run remotely a different way:
exec('select DISTINCT(IP_PLANT_AREA) as plant, MAX(IP_INPUT_TIME) as last_update_time from ip_analogdef GROUP BY ip_plant_area order by last_update_time') on MyServer
This query is written to execute the whole query on the remote system and so the ORDER BY sorts using timestamp order.
There are two ways to make Query 1 return the correct data set:
Add an explicit conversion to timestamp to the query:
select DISTINCT(IP_PLANT_AREA) as plant,
MAX(cast(IP_INPUT_TIME as timestamp)) as last_update_time
from MyServer.ip_analogdef
GROUP BY ip_plant_area
order by last_update_time;
or
Go to the Advanced dialog of the SQLplus ODBC data source an removing the check mark from the Timestamp sent as Character option. You will need to disconnect the link or restart the query writer for this to take effect.

Problem Statement: Executing a SQLPlus script will retrieve the result until the execution end of the query, sometimes you will need to ensure that the query is working properly during execution so that you can continue or cancel it on proper time, specially if the query requiere a lot of time to execute. Even when there is no direct | Solution: to achieve this, in thisSolution we provides an example on how to pause a query, check the current result, and continue its operation using the SET OUTPUT statement and Temporary tables in Aspen SQL PLus.
Solution
The attached .sql file provides an example on how to pause a query to retrieve the name for all the records in the IP_AnalogDef definition family. The script will run the main query inside a FOR-DO statement and write the result in a temporary table called MyTempTable. For every loop inside the FOR-DO statement it will add a value to the index variable and check if this value is equal to the user defined number of row to process (set to 10 by default).
FOR (SELECT name FROM ip_analogdef) do
index = index + 1;
INSERT INTO MODULE.MyTempTable
VALUES (name);
END
When the number of processed rows has been reached, then a function will ask for the user if he want to write the query result until the current execution using a PROMPT windows; this will pause the execution of the query until it have an answer of the user.
At this point, if the user response is YES then it will change the default result output from console to a text file (C:\Temp\QueryResult.txt) using the SET OUTPUT statement, and write the content of the temporary table that was holding the main query result into this file. It is important at this point to return the output result to DEFAULT in the query code so that the data can be actually written down to the text file.
After this, the query will ask the user how many rows does he want to process until next stop using also a PROMPT windows to pause the query. At this point you can open the QueryResult.txt file and look the result of the query until this point.
After giving a number (10 by default) it will continue with the main query, writing the result in the temporary table and repeat all described process again.
If in any PROMPT window the Cancel option is selected, the query will cancel execution and stop. If some text result has been written to the text file, it will remain on it. Also, if the number of rows to process is bigger than the actual query result, the query will not show any PROMPT window and the text file will be empty, in this case you can change the default 10 to a lower value.

Problem Statement: Advanced Process Control V7.2 | Solution: The following enhancements were made to aspenONE APC in V7.2.
Product Quality
The communication layer for APC Products (CORBA/Dais) has been replaced with WCF (.NET) technology in order to improve the robustness and stability of application such as the Production Control Webserver. Dais is still available for v7.2 if required.
A considerable number of quality improvements were made across the entire product suite. A full list of the hundreds of backlog defects addressed are available in the release notes. Some highlighted usability improvements are:
Many backlog defects fixed in DMCplus Controller (primarily fixes in the area of usability and following Windows standards)
Model drag and drop integration between DMCplus Model and the desktop for the Aspen Control Platform
Improved messages from ID engine to help pinpoint problem independent variables (e.g. small moves or no moves)
Documentation improvements for the entry dictionary and new topics for identification and validation concepts
As part of this initiative, many features specifically requested by the user community (via user group voting) have been addressed:
The installation procedure for APC products has been streamlined and the number of discrete installs has been reduced from 16 product-based installs to just 5 server-based installs (including Aspen Process Sequencer). The benefits of this are:
Obvious user choices at install time
Fully supported side-by-side installs of future versions of the desktops (V7.1 and forward)
Easier customer support due to fewer install permutations
Supports more stringent security rules in place on Windows Vista, Windows 7, and Server 2008
An improved user interface for APC Manage has been made available for v7.2. The DOS version is still available and Manage functionality is still available in the Production Control Web Viewer and the Aspen Control Platform Desktop (for ACP applications). However DOS programs that access shared memory files are not consistent with Microsoft Security protocols and so this new windows interface has been created.
DMCplus Modernization Program - .NET Control Environment
AspenTech's commitment to the modernization of its control products has continued with v7.2. Full AspenTech DMCplus Controller functionality has now been migrated to the new .NET control environment. This platform can now handle large DMCplus controller applications which incorporate subcontrollers and SmartStep testgroups.
The v7.2 .NET control environment does not yet support Aspen DMCplus Composite applications. Until v7.3 applications requiring a Composite layer will still be required to use the tradition toolset architecture.
The v7.2 .NET control environment supports the following new capability
DMCplus Subcontrollers
SmartStep Testgroups
Full application (.CCF) import and export
CCF and Aspen Calc Scripts
Drag and drop interplay with DMCplus Model
Transform information appended to .mdl file to enable transform information to be imported directly into the platform with the .mdl file.
Faster processing of models on historical data
Modern, intuitive and guided workflow for DMCplus applications.
PCWS communication with multiple servers for .NET control applications facilitating enterprise roll-ups.
Adaptive Modeling
Aspen Adaptive Modeling was released in January 2010 for application to traditional DMCplus applications. V7.2 delivers Adaptive Modeling capability for DMCplus applications running in the new .NET control environment.
V7.2 Adaptive Modeling capability includes:
Online Model Performance KPIs:
Gain Multiplier Test: A GMULT is calculated for each model. If the GMULT is close to or equal to 1 then the current gain of the model is consistent with the new case data. The model is declared good for the GMULT Test.
Model Uncertainty Test: A model uncertainty test is also performed. If the model uncertainty test indicates high model certainty then the model is labeled as good or bad. If the model uncertainty test indicates high model uncertainty then the model quality is labeled as Unknown.
Independent Variable KPIs (e.g. Oscillation detection; stepsize; limit tests etc.)
Dependent Variable KPIs (e.g. On/Off Status; Prediction Error test; limit tests etc.)
Automated data collection
Auto data preprocessing
Calculations applied to remove outliers, bad values etc.
Online model identification
Online model viewing and export
Model fidelity tests
Fully integrated with Production Control Web Viewer for remote support

Problem Statement: Where can information be found to interpret Aspen Cim-IO error codes? | Solution: The directory C:\Program Files\AspenTech\CIM-IO\etc
contains the .def files for the available Aspen Cim-IO interfaces.
These .def files contain the messages associated with each error code generated by that interface.
Each interface has it's own Facility Number, for instance, the Facility number for the Aspen Cim-IO to Opc is 77.
There are also a series of error messages that being with this facility number. For instance error message 77031 would be found in the cimio_opc.def file,
NOVALIDITEMS,77031,No Valid Items in the list, all the tags in the list are invalid.
Once in the C:\Program Files\AspenTech\Cim-IO\etc directory, you can do a search on the error number, or perhaps the facility number, either search would lead you to the appropriate definition file.

Problem Statement: What is the significance of rank 1000 for a control variable (CV) limit/external target (ET)? and when it should be used? | Solution: Rank 1000 allows implementation of soft constraints on a DMCplus controller. The steady state optimizer (SSO) in DMCplus engine performs two sets of calculations:
· The first part is feasibility check where all the CV limits/ET are checked for feasibility in increasing rank order. For more information about CV ranking, seeSolution 136542.
· The second part of the SSO is to minimize the overall cost of the controller or operate the controller at its economic optimum. This only happens if there is more than one feasibleSolution after the feasibility check. The cost functions used for this calculation is determined as the sum of all MVs's changes multiple by their respective steady state cost.
Typically, any CV limit/ET would have to be satisfied before any optimization occurs. However, any CV limit/ET placed in rank 1000 would not be solved during the feasibility check. It is solved together with the economic optimization (MV costs). The SSO minimizes the overall cost that includes MV cost as well as any weighed CV limit/ET violations (the weighting factor is the inverse of the user-specified steady state (SS) ECE values.
It is now possible to trade off between CV limit/ET violations and MV cost. For example, if pass-balancing CVs are not in the rank 1000, the controller will always balance the passes first before pursuing other economics objectives such as maximizing throughput. If the pass-balancing CVs are placed in rank 1000, the tuning (MV costs and SS ECE) determines whether the controller should pass-balancing before maximizing throughput or it should forgo pass balancing in favor for maximizing throughput.
Because it is possible to give up on CV limit/ET in rank 1000 in favor of economics objectives, they are called soft constraints.

Problem Statement: Logical condition tests involving single precision Aspen InfoPlus.21 (IP.21) variables do not work correctly under some conditions (depending on the original value in IP.21).
Here's an example script, using the IP_AnalogDef record Precision_Test, which will help you reproduce the problem:
-- ------ Start of script
-- Setup: need to create the RealFormatDef record F26.15
-- and the IP_AnalogDef record Precision_Test
LOCAL value REAL,
dbvalue REAL;
value = 7.3;
Precision_Test.ip_input_value = value;
dbvalue = Precision_Test.ip_input_value;
write cast(value as char using 'F26.15');
write cast(dbvalue as char using 'F26.15');
IF value < dbvalue THEN
write 'Less than'; ELSE
write 'Not less than'; END
IF value = dbvalue THEN
write 'Equal'; ELSE
write 'Not equal'; END
IF value > dbvalue THEN
write 'Greater than'; ELSE
write 'Not greater than'; END
-- ------ End of script
On execution, the script gives this result:
7.30000000000000
7.30000019073486
Less than
Equal
Not greater than
The results depend on the value used (for instance, 8.4 gives Equal to and Greater than), while integer values, and halves (like 7.5, 8.5, etc.) work properly. | Solution: This conflict occurs because records such as IP_AnalogDef use single precision reals, whereas SQLplus only uses double precision.
The above SQL script can be made to work correctly by changing the following two lines:
Precision_Test.ip_input_value = value;
dbvalue = Precision_Test.ip_input_value;
to:
Precision_Test.ip_input_value= ROUND(value,1);
dbvalue= ROUND(Precision_Test.ip_input_value,1);

Problem Statement: Is it possible to break out of a FOR loop before its set number of iterations? | Solution: There are several ways to handle this.
1. Using an Error Handling Block
2. Using a nested IF statement
3. Using a WHILE statement.
4. Using a function call with a return statement.
One might think that forcing the counter to its limit or beyond its limit would cause the looping to stop. This does not work. The following example demonstrates this.
local x int;
local y int;
local z int;
y = 2;
for x = 1 to 10 do
z = x + y;
write 'z = ' || z;
if z = 5 then
x = 11;
end
write 'x = ' || x;
write ' ';
end;
write 'Loop ended.';
This results in the following output.
x = 11
z = 6
x = 4
z = 7
x = 5
z = 8
x = 6
z = 9
x = 7
z = 10
x = 8
z = 11
x = 9
z = 12
x = 10
Loop ended.
As evidenced by these results, changes to X inside the loop are only temporary (inside the loop). The variable is later updated by the loop as if nothing has happened. The loop simply continues processing where it left off.
Method 1
Error Handling
An Error Handling Block can be added around the FOR loop. Then, by forcing an error inside the loop, you cause the logic to jump to the Exception logic.
An example of using an Error Handling Block is given below:
local x int;
local y int;
local z int;
y = 2;
begin
for x = 1 to 10 do
z = x + y;
write 'z = ' || z;
if z = 5 then
ERROR 'MY_ERROR_CODE', 'Want to break out';
end
write 'x = ' || x;
write ' ';
end
exception
write 'Loop ended.';
end
This results in the output:
z = 3
x = 1
z = 4
x = 2
z = 5
Loop ended.
In the EXCEPTION block, you need to have at least one statement, even if it doesn't really do anything. You can also substitute your own error code for MY_ERROR_CODE and use a CASE statement inside the EXCEPTION block to determine which error was encountered. But, for this example, that is not required. More information about using an EXCEPTION statement can be found in the SQLplus User's Manual.
NOTE: There is a side effect to using the EXCEPTION block. When triggering an error, SQLplus resets the OUTPUT to the default destination. Therefore, if you have set the output to another location, you must reset it after the error occurs. This can be done either inside or after the EXCEPTION block.
Method 2
Nested IF Statement
An IF statement can be added inside the FOR loop to determine if the logic needs to be processed. With this method, the loop does execute all the way through and the IF statement is executed every time. However, logic inside the IF statement is only processed when the conditions are met.
for x = 1 to 10 do
if answer_found <> 1 then
z = x + y; write 'z = ' || z;
if z = 5 then
answer_found = 1;
end;
write 'x = ' || x;
x = x + 1;
end; -- answer found <> 1
end;
write 'Loop ended.';
This results in the output:
z = 3
x = 1
z = 4
x = 2
z = 5
x = 3
Loop ended.
Method 3
WHILE Statement
A WHILE statement can be used in place of an IF statement. When using a WHILE statement, the query writer is responsible for incrementing any counter. A counter is not necessary in a WHILE loop (unless the counter is required by logic within the loop). The WHILE statement only needs a criterion telling the loop to continue as long as the criterion is met.
local x int;
local y int;
local z int;
local answer_found int;
y = 2;
x = 1;
answer_found = 0;
while x <= 10 and answer_found <> 1 DO
z = x + y;
write 'z = ' || z;
if
z = 5 then
answer_found = 1;
end
write 'x = ' || x;
x = x + 1;
end;
write 'Loop ended.';
This results in the output:
z = 3
x = 1
z = 4
x = 2
z = 5
x = 3
Loop ended.
Method 4
Function Call
Another way to exit the FOR or WHILE loop is with the RETURN statement. This statement is used to exit (return from) a function or procedure. This method is a more complex. However, it is valuable when compartmentalizing logic that will be used in more than one place within the query.
function loop_function(z int)
local x int;
local y int;
y = 2;
for x = 1 to 10 do
z = x + y;
write 'z = ' || z;
if
i = 5 then
return;
end
write 'x = ' || x;
end
end
This results in the output:
z = 3
x = 1
z = 4
x = 2
z = 5

Problem Statement: How to put the result of a Select statement (i.e. Select_Description) into a character variable. | Solution: Here is an example query that would put the result of a Select statement (i.e. Select_Description) into a character variable:
local temp char (20);
temp = (select select_description from eng-units where OCCNUM=2);
write temp;
If you would like to capture more than one variable, you can use a FOR loop (even though it will only go around the loop once).
Here is the syntax:
local temp char (20);
local temp2 char (20);
for (select name,select_description from eng-units where OCCNUM=2) do
temp = name;
temp2 = select_description;
end
write temp;

Problem Statement: Technical Advisory: CIM-IO to replace Scan/21, Phoenix and Direct Connect interfaces by early 2000 | Solution: With the powerful and robust technology that is available in the latest version of our products, Aspen is supporting some of its older interfacing methods by providing a path forward to our current interface technology, CIM-IO. Aspen Tech will be retiring all current SCAN/21 interfaces when InfoPlus.21 v3.0 is released in early 2000. Aspen Tech Support will work with all current CIM/21 customers to migrate the existing SCAN/21 interfaces over to CIM-IO. Setcim and InfoPlus-X customers can continue to use Direct Connect and Phoenix interfaces, but should be aware that the support path forward is migration to CIM-IO. Setcon and InfoPlus customers should be aware that the migration path to CIM-IO must also include an update of the historian.
CIM-IO is the standard interface used by all Aspen Tech products such as InfoPlus.21 and DMCplus. The CIM-IO interfaces and CIM-IO Bridge (Scan/21 for CIM-IO) are available to all customers with current support contracts at no additional license fee. If custom utilities exist, it will be necessary to work with the Services group to determine what modifications are necessary and arrange for a quote for those services.
If you need to order the CIM-IO Bridge, please contact the Seattle Support group to discuss migration. For the CIM-IO equivalent of a Phoenix or Direct Connect interface, please contact the Houston Support group.
The linked Microsoft Word document above has a table which shows the particular migration path for specific Phoenix and Direct Connect interfaces.

Problem Statement: A delay may appear when using the Aspen SQLplus SYSTEM command to check files and folders in Windows Server 2008 or Windows Vista when compared to accessing the files directly from Windows Explorer. This knowledge base article describes the cause of this delay and the re | Solution: .Solution
In Windows Vista and Windows Server 2008 a new Server Message Block file sharing protocol was released.
Server Message Blocks Protocol (SMB) is the file sharing protocol used by default on Windows-based computers. SMB 1.0 was designed for earlier Windows network OS such as Microsoft LAN Manager and Windows for Workgroups, but until Windows Server 2008 and Vista, all Microsoft-based operating systems continued to use it more or less in its original format.
Below there are methods for changing both client and server, and when using the terms client and server it does not mean that a client OS such as Windows Vista always connects to a server OS such as Windows Server 2008. Sometimes a Vista computer will connect to another Vista computer and, in that case, the computer that is serving the shares is considered to be the server.
To disable SMB 2.0 for Windows Vista or Windows Server 2008 systems that are the client systems run the following commands in a DOS command prompt box:
sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled
Note there's an extra (space) after the = sign.
To enable back SMB 2.0 for Windows Vista or Windows Server 2008 systems that are the client systems run the following commands, again in a DOS command prompt box:
sc config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc config mrxsmb20 start= auto
N.B. The following changes require editing the registry. Always back up the system registry prior to making any changes.
In order to disable SMB 2.0 on the server computer:
1 ) Run regedit on Windows Server 2008 based computer.
2 ) Expand and locate the sub tree as follows:
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
3 ) Add a new REG_DWORD key with the name of Smb2 (without quotation mark)
Value name: Smb2
Value type: REG_DWORD
0 = disabled
1 = enabled
Set the value to 0 to disable SMB 2.0, or set it to 1 to re-enable SMB 2.0.
4 ) Reboot the server.

Problem Statement: SQLplus is not returning the output in the same order as it appears in the CROSS BY query | Solution: SQLplus does not adjust the order of the results of a query. It simply returns the results of a query in the order the data is returned from the database, by record ID, which may or may not be the same order of the script itself.
If you want to control the order of the columns, use a JOINS query (instead of CROSS BY), like the following example:
select a.ts, a.value as ATCL102, b.value as ATCAI, c.value as ATCL101
from history a, history b, history c
where a.name = 'ATCL102' and b.name = 'ATCAI' and c.name = 'ATCL101'
and a.ts between '13:00' and '14:00' and a.period = 00:01:00;
With this query, the output columns will be displayed in the order they were requested.

Problem Statement: It sometimes becomes necessary to exit a WHILE loop if more than one condition is met. Although this feature is not documented, it is supported in SQLplus. An example of when this might be useful is when one needs to limit the maximum number of iterations in a convergence loop. | Solution: In this example, one has a WHILE loop to check convergence of a value as is common in many thermodynamic calculations. Full convergence calculations are not done here so that this example can stay as simple as possible. There are two points to notice in this script. Namely, changing the value of i to less than 0.1 will stop the loop. If this is set before the WHILE loop, then the loop will never execute. In addition, when the loop counter equals 15 the loop will stop.
-- beginning of example script, this script will run in SQLplus
LOCAL x REAL; -- this could be a convergence check.
LOCAL j INTEGER; -- this could be a loop counter set at 15
x = 0.2; -- loop convergence variable is initialized here but should actually be calculated in the WHILE loop
j = 0;
WHILE (j < 15 AND x > 0.1) DO -- 0.1 is the tolerance for the convergence
-- do some calculation on x for convergence such as x = ABS( temp2 - temp1 ) / temp1
j = j + 1;
WRITE ''x = ''|| x || '' j = ''|| j ;

Problem Statement: The following Daylight Savings Time adjustment to the cimio_timezone.def file is required for Cim-IO Core running on OpenVMS (VAX or ALPHA), when the system time is changed to daylight savings (DST) or Standard Time (ST). If the Cim-IO client or server is running on OpenVMS the cimio_timezone.def file must be adjusted to ensure the data going into SetCim or Infoplus.21 has the correct time relative to UTC (GMT). The Cim-IO client or server running on OpenVMS must be restarted to recognize the new value in the cimio_timezone.def file.
Note: This change is not required if running SetCim Version 4.6 or earlier and both the Cim-IO client and server are on the same OpenVMS host machine. | Solution: Suggested procedure for adjusting cimio_timezone.def on a OpenVMS host:
1. Stop Cim-IO client and/or server.
2. Adjust the VMS system time.
3. Edit the value in the file cimio_timezone.def (usually found in the location SETCIM:[ETC] or CIMIOROOT:[ETC]) and adjust it to reflect the current offset between VMS system time and UTC (GMT). The number entered is an integer number representing the whole hour offset between VMS system time and UTC, expressed as a positive value for time zones west of (GMT) and a negative value for time zones east of (GMT).
4. Restart Cim-IO client and/or server.
Examples (northern hemisphere):
For Houston, Texas which is west of Greenwich the local time offset to UTC(GMT) is 6 hours standard time and 5 hours daylight savings time. The cimio_timezone.def file on a OpenVMS machine would be edited and the current entry of 6 would be changed to 5 for the change to DST. In the fall the reverse change would be made to this file to change from DST to standard time.
For Berlin, Germany which is east of Greenwich the local time offset to UTC is 1 hour standard time and 2 hours daylight savings time. The cimio_timezone.def file on a VMS machine would be edited and the current entry of -1 would be changed to -2 for the change to DST. In the fall the reverse change would be made to this file to change from DST to standard time.

Problem Statement: I have a stream that runs at certain times of the day, but will vary from day to day and I want a way to show the data from the most recent run time of the stream as a table in AspenOne Process Explorer. The data shown should be the stream's flow rate and the times should be equally incremented over the run-time of the stream. | Solution: ThisSolution documents a method to use Aspen SQLplus in order to write stream values at four equal time intervals that update live as a stream is running and displays the quarter marks for the most recent run if the stream is inactive. For this example, suppose a stream's flow rate is stored in tag ATCAI and the value is displayed as 0 when it is not running.
Doing this will require storing a Aspen SQLplus script to activate when the stream receives a new value into the Aspen InfoPlus.21 database as well as the creation of one new tag for each slice of time that the data is needed for. To do this, we will define endpoint variables that show the start and end times of the stream and the remainder of the variables will be used to store data into the newly created tags in the Aspen InfoPlus.21 database.
In the example below, we wish to store the information for when the stream ATCAI is running, which is denoted if the tag value is greater than 0. ATCAITEST1, ATCAITEST2, ATCAITEST3, ATCAITEST4 being the four equally incremented time periods where we are outputting information. The following query will put the timestamp of the query into the description field and will put the value of the tag at that timestamp into the input value field:
local A,B,C,D; --A and B for time endpoints, C for the time increment, D for storing retrieval time
A = (select IP_TREND_TIME from ATCAI where IP_TREND_VALUE <= 0);
B = (select IP_INPUT_TIME from ATCAI);
C = (A-B)/4;
D = Cast (C+B as timestamp);
update ATCAITEST1 set IP_DESCRIPTION = (Cast (D as char));
update ATCAITEST1 set IP_INPUT_VALUE =
(select IP_TREND_VALUE from ATCAI where IP_TREND_TIME < D);
D = Cast (C+D as timestamp);
update ATCAITEST2 set IP_DESCRIPTION = (Cast (D as char));
update ATCAITEST2 set IP_INPUT_VALUE =
(select IP_TREND_VALUE from ATCAI where IP_TREND_TIME < D);
D = Cast (C+D as timestamp);
update ATCAITEST3 set IP_DESCRIPTION = (Cast (D as char));
update ATCAITEST3 set IP_INPUT_VALUE =
(select IP_TREND_VALUE from ATCAI where IP_TREND_TIME < D);
D = Cast (C+D as timestamp);
update ATCAITEST4 set IP_DESCRIPTION = (Cast (D as char));
update ATCAITEST4 set IP_INPUT_VALUE =
(select IP_TREND_VALUE from ATCAI where IP_TREND_TIME < D);
To automate this query, simply go to Record | Save and name the QueryDef or CompQueryDef record and assign it a task for processing. Once that is complete, go to the Aspen InfoPlus.21 Administrator and find the Query that was just written and change the #WAIT_FOR_COS_FIELDS to 1 and specify the change of state parameter to run the query whenever the stream is active. For this example, the field will be set to >0 as the stream is active as long as the value is positive. This way, the tags will stop updating when the stream turns off and only the most recent stream data is shown. The current values and description of the tags ATCAITEST# will show the value at the timestamp shown in the description. The values will show up equally incremented in time. The following is a sample calculation made using thisSolution
The tag values can now to used in a table and when published to AspenONE Process Explorer, will be published in real time

Problem Statement: The purpose of this | Solution: is to outline how to solve the problem where data coming into a Setcim or InfoPlus.21 database from a Cim-IO server running VMS is timestamped differently from the current, system time.
The symptoms of the problem are:
The system time on both the I+.21 server/Cim-IO client (NT) are current, and the timetamp on the Cim-IO server (VMS) is also current.
Running the Cim-IO test program (cimio_t_api) on both the Cim-IO server and client returned the current time (using #1: Test Cim-IO time functions).
The Get record containing the data records (i.e analog records, discrete records, etc.) have an IO_LAST_UPDATE of the current time (IO_LAST_STATUS can be Success).
When manually inputting data into the IP_INPUT_VALUE field of the analog record, it updates the IP_INPUT_TIME with the current time.
The only place that the timestamp is not the current time is in the IP_INPUT_TIME field of the analog record when it is updated by Cim-IO, and as a result, the IP_VALUE_TIME and IP_TREND_TIME's (and in the historian).Solution
The reason for this problem is that the time server call that VMS systems make return GMT. It is necessary to tell Cim-IO how many hours it must add or subtract to or from GMT to get the local time. The CIMIO_TIMEZONE.DEF file is used for this purpose.
The CIMIO_TIMEZONE.DEF file is located on both the Cim-IO server and the Cim-IO client:
Cim-IO Server: $CIMIOETC
Cim-IO Client: %SETCIMETC%
In this file, you make a single entry: a signed integer representing the number of hours west (positive) or east (negative) of GMT, with the appropriate sign.
IMPORTANT NOTES:
*** This change should be made on the Cim-IO server file. ***
For positive time differences (i.e west of GMT), you do not have to enter the + sign: simply enter the hour integer value.

Problem Statement: When trying to connect an aspen SQLplus client to an Aspen InfoPlus.21 server, the following error messages may sometimes appear:
Error: Unable to get client user context
Error: Unable to access a secured SQLplus server due to incompatible SQLplus client! | Solution: The problem is that the SQLplus server task is unable to find out who you are logged in as. Usually it relates to Win9x client PC's that do not use secure login or clients that are not on a (trusted) Windows domain. The problem has at its core Windows authentication problems. The SQLplus server task at the InfoPlus.21 node doesn't recognize the Windows account used by the client node.
To bypass this problem, add a -n to your port number in the command line parameters of your TSK_SQL_SERVER task in the IP.21 manager. Your command line parameters should then look like this: 10014 -n. This will allow the SQLPlus client machines to connect without authenticating the users, but you will not be able to use security. If you would like to restrict your users from writing data via SQLplus to the IP.21 database, you can add a -r so the command line parameter becomes: 10014 -n -r

Problem Statement: There may be situation in which you want to retrieve information on what machines are connecting to the Aspen InfoPlus.21 database using Aspen InfoPlus.21 Administrator, Aspen Process Explorer, Aspen SQLplus Query Writer, etc. This | Solution: aims to provide an example of how an Aspen SQLplus script can be used to retrieve the machines that are connected.Solution
There are a few important points to note.
1. The account used to run the Aspen SQLplus script must have permission to Windows Management Instrumentation (WMI).
2. The WMI version must support the use of CommandLine property from Win32_Process. This is a new property for Windows XP. Windows 2003 Server has this new property.
3. The account must have permission to execute SYSTEM command in Aspen SQLplus.
4. The account must have permission to execute Netstat.
5. Netstat must be able to display active TCP connections and includes the process ID (PID) for each connection. This will mean that the -o option is available to be used with Netstat. This parameter is available on Microsoft Windows XP and Windows Server 2003.
6. The Aspen SQLplus script is written to run on the Aspen InfoPlus.21 machine though you should be able to modify it to run on a remote machine.
The attached Aspen SQLplus script will be able to list out the connections to the following tasks:
TSK_ADMIN_SERVER
TSK_APEX_SERVER
TSK_EXCEL_SERVER
TSK_DEFAULT_SERVER
TSK_BATCH21_SERVER
TSK_SQL_SERVER
The attached SQL script is provided AS IS to provide a sample and will not be supported by AspenTech Support.
Additional Tips:
For TSK_SQL_SERVER, the Aspen SQLplus script is written to detect the default port, 10014. If you are using any other port, changed the line which is assigning the variable SQLport to the port you used.
If you are unable to create WMI in Aspen SQLplus but are able to use WMI through command cscript.exe execution, rewrite the WMI portion to be executed through cscript.exe and have the output written to a file. In Aspen SQLplus, you will need to have permission to the SYSTEM command in order to execute cscript.exe. You will need to simply read the output file of WIMI execution using cscript.exe to update the Process ID of the tasks into the temporary table MODULE.Task.
If you are going to save the Aspen SQLplus script as a QueryDef record, note that the script is not written to take into account of the 80 characters length limit of QueryDef. Some modification may be needed. Alternatively, you can save it as a CompQueryDef.
You can create custom definition and another set of Aspen SQLplus script that will update the custom definition with the information such as timestamp, task, foreign IP.address. In this way, when it is scheduled to run frequently, with the timestamp of the start of the connection and end of the connection, you can approximate the length of time for the connection and the period of connection. You can choose to use Aspen InfoPlus.21 historian or any other relational database to store the information.

Problem Statement: How can I connect my SQLplus Query Writer tool to my Setcim or IP-X on an Alpha via ODBC but have it be read-only? | Solution: To Change An Existing Service to Read-only:
Login to Alpha
Type UCX to enter UCX management tool.
Type show services to see existing services. Find the SQL service (something like SQLP10014, SQLPportnumber ,SQLPxxxxx).
Disable the current SQL service by typing disable service SQLPxxxxx
Change the command file that the service points to. The existing file should be SETCIMCOM:SQLPLUSNET.COM. This will be changed to SETCIMCOM:SQLPLUSNETRO.COM. Type: set service SQLPxxxxx /file=SETCIMCOM:SQLPLUSNETRO.COM
Make the service enabled again by typing enable service SQLPxxxxx
Check the service to make sure it is configured with the correct file by typing show service SQLPxxxxx /full
You should be able to connect to the port number through ODBC, but as a read-only connection. You can test this by trying to update something through SQLplus on a PC.
The SQLPLUSNETRO.COM is a small com file to handle the VMS command procedures. Basically, your SQLPLUSNETRO.COM file is a copy of your SQLPLUSNET.COM file with a few modifications. Set your privileges (suggest TMPMBX, NETMBX), set up a symbol for the sqlplusnet.exe, and then pass the symbol a parameter of r for read only. Then comment out the line that RUNs the .EXE.

Problem Statement: Why can't I use the value of a MACRO definition immediately after defining it? | Solution: SQLplus requires a statement between the MACRO definition and its use. This statement can be anything including a null statement (;).
For Example, the following does not work:
MACRO TestMacro='RC345';
'&TestMacro'->Value=10;
The problem is that SQLplus has read the next token after the ; before it has executed the macro statement. This only happens when the macro is used in the first token after the ;, so the following two examples work. The first, because an additional ; was added and the second, because the macro isn't the first token after the ;
MACRO TestMacro='RC345';;
'&TestMacro'->Value=10;
MACRO a 'DefinitionDef';
SELECT * FROM &a;

Problem Statement: Why does SQLPlus return only 99 columns when using the Cross By query? | Solution: There is a limit on the number of columns in a cross query. The default for this limit is 100 but a different Value can be specified with a FIRST clause after the BY.
Example:
Select ts, max(value) by name first 200 from history
Where name in (select name from ip_analogdef)
Group By ts;

Problem Statement: A user is trying to create an event from an Aspen SQLplus script using 'e21_chg_key' and 'e21_rec_evnt' commands but SQLplus does not seem to recognize these commands.
This KB article shows a couple of methods to create an event in Aspen Event.21. | Solution: There are two command line programs, e21_chg_keys.exe and e21_rec_event.exe, that can be used to accomplish that. They are located at:
Program Files\AspenTech\InfoPlus.21\c21\e21\server\e21_chg_keys.exe
Program Files\AspenTech\InfoPlus.21\c21\e21\server\e21_rec_event.exe
But some users do not like these .Net versions because they start up slower than when they use the Aspen Event.21 API, which is much faster.
The Event.21 API and samples get installed with Event.21 client (PE) to
Program Files\AspenTech\APEx\Samples\EventPlots\API

Problem Statement: What files are required when I am asked to submit my workspace libraries to reproduce an issue? What files are required by AspenTech Support to reproduce my issue? | Solution: To reproduce the issue, we need:
1. Workspace libraries
2.Configuration file
3. Backup of the workspace
Workspace Libraries
The workspace libraries are found on your server machine at the location below:
..\\AspenZyqadServer\AspenZyqadxx.x\WorkspaceLibraries.
The best thing would be to zip up your Workspaceslibraries folder. You can keep the path structure when zipping up the folder and files.
Configuration file
You need to mention that which configuration file (*.cfg) under workspacelibraries folder is used by your workspace or you can send us the workspace.cfg file found in your workspace folder which is typically under
..\\AspenZyqadServer\AspenZyqadxx.x\Workspaces\WorkspaceName folder
Backup of the workspace
We may need your workspace data to reproduce the issue. You can use backup utility (AZ***Backup.exe) under ..\Program Files \AspenTech\Basic Engineering V*.*\DataServices\bin to create a backup of the workspace. You can checkSolution 127109 to learn how to create backup of the workspace.

Problem Statement: When trying to connect the SQLplus Query Writer Tool on the PC or the SQLplus Query Writer for Motif on the Setcim server to the Oracle database, this error is received:
Failed to connect to link <link name>:
Error while trying to retrieve text for error: ORA-12203. | Solution: The SQLplus 4.8 User's Manual starting on page 2-3 describes the complete installation and configuration required to run SQLplus. Page 2-10 discusses Enabling Oracle Access. Basically, SQLplus requires Oracle logical names to be defined before it can access the Oracle database. These logical names are set up using an ORAUSER file. This file is usually located at:
disk:[oracle7.code.util]orauser.com
where disk is the name of the disk where SQL*Net is installed. The manual states that this ORAUSER.COM file should be called from the LOGIN.COM file in the SETCIM:[SQL] directory. Instead, this ORAUSER.COM file needs to be called from the SQLPLUSNET.COM file in the SETCIMCOM directory.

Problem Statement: If an SQLplus client is attempting to connect to an unresponsive or powered down SQLplus server, the client can take a (seemingly) long time to return a no connect error. However, it is possible to minimize the timeout period by adjusting TCP/IP registry settings.
The following Tech Tip provides directions on changing one such variable. | Solution: The timeout period for connecting either the Query Writer or Desktop ODBC to an SQLplus server is partially controlled by the registry setting TcpMaxConnectRetransmissions. This parameter specifies the number of times the server will attempt to retransmit a connection acknowledgement before aborting the connection. On a Windows NT 4.0 computer, the default value for TcpMaxConnectRetransmissions is set to 3. The timeout period for each reconnection is doubled, with an initial timeout period of 3 seconds. This gives a total timeout of 45 seconds (3+6+12+24 = 45) for an NT computer.
To help decrease the total timeout period, it is possible to change the TcpMaxConnectRetransmissions setting. This will help lower the amount of time the client needs to acknowledge that the SQLplus server is not responding. This variable is set on the SQLplus client, since it is the machine initiating the request.
To set this registry key:
Open HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TcpIp\Parameters on the SQLplus client.
Create a DWORD value called TcpMaxConnectRetransmissions
Set the value to 1, which will give a total timeout value of about 9 seconds (3+6).
Reboot the computer for the parameter to take effect.
Note: This timeout is the default for all TCP/IP connections, not just SQLplus.

Problem Statement: What Aspen InfoPlus.21 tasks are the ProcedureDef records run on?
Are these records run by a single Aspen InfoPlus.21 task? | Solution: The Aspen SQLplus product uses external TSK_IQ tasks (i.e. tasks that start an occurrence of the C:\Program Files\AspenTech\InfoPlus.21\db21\code\iqtask.exe executable) to run queries and procedures.
Stored Procedures are always executed on the same task as the query that calls them. For example, if a QueryDef record is on TSK_IQ2 and it calls a stored procedure, the stored procedure will also be executed by TSK_IQ2. So, there is no reason to try to change the EXTERNAL_TASK_RECORD for a stored procedure.
SQLplus recognizes that a record is a stored procedure by the fact that its definition record has a record activation code of 4 and an external task record of TSK_IQ1. If you change the External_Task_Record for ProcedureDef it will not be recognized as a stored procedure definition record.

Problem Statement: How to find an InfoPlus.21 record's folder and the various sequence of parent folders. | Solution: This example will return a string with the name of the record and the folder structure.
Function FolderTree(n1 record)
local tmp string;
tmp = '/' || n1;
n1 = (SELECT name FROM Folderdef WHERE record_name = n1);
WHILE n1 IS NOT NULL DO
tmp = '/' || n1->name || tmp ;
n1 = (SELECT FOLDER_PARENT FROM Folderdef WHERE name = n1->name);
end;
return tmp;
end;
Save this function as a ProcedureDef record in InfoPlus.21. Call the procedure and pass it the name of the desired record. For example:
write FolderTree('atcai');
The output will look similar to this '/RootFolder/Folders/OPC_tags/3down/ATCAI'

Problem Statement: Is there a way to use SQLplus, either in the Query Writer Tool or via ODBC, to connect to an Excel spreadsheet while the spreadsheet is open and avoid this error:
failed to connect to link....it is already opened exclusively by another user or you need permission to view its data... | Solution: Make the Excel Workbook shared. To do this:
1. Open the workbook in Excel.
2. Selected Tools/Share Workbook... from the menu.
3. Check the Allow changes by more than one user at the same time box.
4. Click OK.
SQLplus will them be able to read the spreadsheet even if it is open by someone else.

Use this command in a DOS box:
C:\>C:\Program Files\AspenTech\InfoPlus.21\db21\code\iq.exe C:\temp\query1.sql name atcai

Problem Statement: Is it possible to subtract a large number of days from a timestamp value? | Solution: You can subtract (or add) values from a timestamp in SQLplus by subtracting the value in 1/10 second intervals. So to subtract 1 day this would be 1*24*60*600 (1 day * 24 hours * 60 minutes * 600 tenths seconds). For example:
local dayvalue int;
local t1 timestamp;
t1 = '01-Mar-14 10:25:30.1';
dayvalue = 35;
write (t1 - dayvalue*24*60*600);
This works fine until you try and use a value of greater than 2485 days, after which the results are incorrect. This is due to specifying local variable type integer. In SQLplus integer is 4 byte value (32-bit) and can store numbers in the range -2147483648 to 2147483647. A day value of 2486 for the calculation uses 2486 * 24 * 60 * 600 = 2147904000 and this exceeds the integer range.
To avoid this problem you can specify the dayvalue as real.

Problem Statement: When executing an SQL script, the following error messages may appear:
Invalid TIMESTAMP value
YEAR field out of range when converting CHARACTER to TIMESTAMP
Invalid timestamp <timestamp>, check format is YYYY-MM-DD HH:MM:SS and numbers are in range
All of these error messages indicate a problem with a timestamp setting within the SQL script. | Solution: Check on the version of Aspen SQLplus used. ISO timestamp formats are only supported in v6.0 and above. A query using ISO timestamp being executed on a pre-v6.0, will result in error messages.
Ensure that Aspen InfoPlus.21 database and the SQL script are configured with the same time setting. To check the time setting for the Aspen InfoPlus.21 database,
1. Launch Aspen InfoPlus.21 Administrator.
2. Right-click on the nodename.
3. Select Properties from the context menu.
4. Select Time Parameters tab.
The Time Parameters tab in the Properties dialog is where the time format setting for Aspen InfoPlus.21 database is configured. In the SQL script, if CAST function is used to cast an expression to timestamp, the date and time format of the expression in the query must match with the date and time format set in the Time Parameters tab in Aspen InfoPlus.21 Administrator.
For example, the date format had been set to DD/MM/YY in the Time Parameters tab.
CAST('06-Sep-07 2:18:00' AS TIMESTAMP);
When the above SQL script is run, the following error message is encountered.
Casting a timestamp character value from the format DD-MON-YY HH:MI:SS to another format using CAST FORMAT results in the error message below.
The below is an example which will give the error message above.
CAST('06-Sep-07 14:18:00' AS TIMESTAMP FORMAT 'MM/DD/YYYY HH:MI:SS' );
There are a few thing to note.
1. The expression given is of the data type CHARACTER.
Running CAST('06-Sep-07 14:18:00' AS TIMESTAMP) will just simply convert it from one data type to another. In this case from CHARACTER to TIMESTAMP.
2. The expression is represented in Aspen InfoPlus.21 format and not in ANSI format.
Running TIMESTAMP '06-Sep-07 14:18:00' will give the following error message.
So it would not be possible to use the following SQL script.
CAST(TIMESTAMP '06-Sep-07 14:18:00' AS CHAR FORMAT 'MM/DD/YYYY HH:MI:SS')
The YYYY-MM-DD HH:MM:SS format is the representation of timestamp in ANSI format and SQL is regulated by the American National Standards Institute (ANSI) which Aspen SQLplus is based on.
In order to CAST FORMAT, the expression need to be CAST into a TIMESTAMP data type first as shown below.
CAST(CAST('06-Sep-07 14:18:00' AS TIMESTAMP) AS CHAR FORMAT 'MM/DD/YYYY HH:MI:SS')

Problem Statement: The EXECUTE and EXEC commands allow you to execute queries on remote nodes. The remote query appears in single quotes following the EXECUTE or EXEC command. If the remote query is long or is complex, it can be difficult to handle in the Aspen SQLplus query writer.
This | Solution: describes how to work around this problem.Solution
Knowledge base article 138104 describes how to split a long EXECUTE command over several lines.
You can also place the command into a text file and read the query from the file as follows:
1) Save the query in a text file, for example C:\Temp\MyQuery.txt
2) Use next SQLplus code:
Local QueryLine;
QueryLine = (Select LINE from 'C:\Temp\MyQuery.txt');
Execute QueryLine
On MyIP21;
Replace the file path inside the QueryLine variable for the path to your file. Note, there is still an absolute limit - LINE pseudo column supports up to 4048 characters.

Problem Statement: How can I recover an automated Aspen SQLplus report that has been deleted? | Solution: When a Aspen SQLplus report is deleted via the web interface then the record that is associated with in the Aspen InfoPlus.21 database definition record SQLReportDef will be deleted. However the XML file associated with the report is still available in the folder Documents and Settings\All Users\Application Data\AspenTech\SQLplus\automated.
The report can be re-instated by
1. Locating a copy of the Aspen InfoPlus.21 snapshot that contains the SQLReportDef record for the report.
2. On a non-production server you should load this snapshot and then create a recload file (.RLD file) for the report record. SeeSolution 108789 for detail on how to create a recload file.
3. Copy the recload file to the production server and load it into the currently running snapshot. SeeSolution 111481 for detail on how to load a recload file into the Aspen InfoPlus.21 database.
4. Verify that the automated report is accessible from the web interface of SQLplus Reporting.
Important: If the XML file doesn't exist then the report will need to recreated via the web interface.

Problem Statement: When you run a query using the Aspen SQLplus Query writer, the default timeout value for the query is 180 seconds; A however, an external task like TSK_IQ1 executing a query defined by QueryDef or CompQueryDef records, by default has no timeout.A This article explains how to add a timeout parameter to an external task that processes a query record, usually referred to as an IQ task. | Solution: Using the Aspen InfoPlus.21 Manager, modify the command line parameters field for the IQ task (TSK_IQ1, for example) to add the switch /t=nn, where nn is the timeout in seconds.A
This switch sets the timeout for all queries processed by the IQ task.A If other query records require a different timeout value, you will need to create a separate IQ task in order to specify a different timeout value.
