32 IBM Content Manager OnDemand Guide
– Creates an authorization list with the same name as the instance. 
– If the instance is in an Independent ASP , a record is added to the file QARLCASP in library 
QUSRRDARS. 
2.4.2  Changing an instance configuration
To change an instance configuration, you must change the configuration parameters in the 
ARS.INI and ARS.CFG files.
Configuration parameters in the ARS.INI file
Y ou might need to change several of the configuration parameters from the values that you 
specified when you ran the CRTINSTOND command before you use this instance for the first 
time. If so, you must edit the ARS.INI file in the /QIBM/UserData/OnDemand/config directory by 
running the following command:
EDTF '/QIBM/UserData/OnDemand/CONFIG/ARS.INI' 
Y ou can change the values that are listed below. The instance definition starts with the line 
[@SRV@_[instance]], where [instance] is the name of the instance. For example, the instance 
ONDTEST starts with the line [@SRV@_ONDTEST]. 
The following lines might need to be reviewed: 
/SM590000PORT=0: The port to which the server listens to receive requests from a Content Manager 
OnDemand client. The value of 0 means to use the default port of 1445. Only one server 
can be listening to a particular port at a specific time. To run multiple instances 
concurrently, you must specify an unused port on your system. Y ou can run the Work with 
TCP/IP Network Sts (WRKTCPSTS) OPTION(*CNN) command to see the ports that are in use 
on your system. 
/SM590000SRVR_FLAGS_SECURITY_EXIT=1: This line specifies that you want to use IBM i user IDs and 
passwords as the Content Manager OnDemand user IDs and passwords. This method is 
the default value, which makes it simpler for your users because they do not have to 
maintain multiple passwords. If your Content Manager OnDemand users do not need to 
have IBM i user IDs, specify a value of 0 for this parameter. When you specify 0, your 
Content Manager OnDemand passwords have no relationship to IBM i passwords.
However, if a Content Manager OnDemand user ID and an IBM i user profile match, 
certain Content Manager OnDemand commands and APIs use the IBM i user profile as 
the Content Manager OnDemand user ID, even if you chose not to relate the two user IDs. 
This situation can permit IBM i users to perform Content Manager OnDemand functions 
that you did not intend for them to perform. Therefore, a Content Manager OnDemand 
user ID must not match an IBM i user profile name unless the two IDs are used by the 
same individual. 
If you change the SRVR_FLAGS_SECURITY_EXIT value, review the Content Manager 
OnDemand System Parameters values (defined by the Content Manager OnDemand 
Administrator Client) for the instance that you changed. For more information, see 
“OnDemand userid relationship to IBM i user profiles” in the IBM Content Manager 
OnDemand for i - Common Server Administration Guide, SC19-2792.
