Breaking Boundaries: Differentiation in Private Equity and Venture Capital Markets
Wednesday, April 13, 2016
University Club of Chicago
Chicago, IL
Even by the standards of the intensely competitive market for private equity and venture capital, today's market environment is particularly challenging. With deal valuations approaching record highs, strategy differentiation has become critical. An abundance of "dry powder" and an influx of new alternative capital providers has led firms to specialize within both industry verticals and investment themes where expertise can drive returns.
The 2016 Private Equity and Venture Capital Conference will address opportunities and challenges in the rapidly-changing industries of healthcare, energy, and technology, and evaluate alternative capital providers such as search funds and celebrity venture capitalists, among many other dynamic topics. Drawing on the insights of some of the market's leading investors, portfolio company executives and industry consultants, the Conference will tackle some of the most pressing issues affecting today's investing climate.
The 2016 conference is proud to feature Stephen G Woodsum, Co-Founder of Summit Partners and Tod Francis, Managing Director of Shasta Ventures as the conference keynote speakers. Our keynotes, as well as six panel discussions, will cover topics including:
- Responding to the Unexpected: Redefining Strategy Post Investment
- The Future of Investing in Energy
- Investing in the Highly-Regulated and Rapidly Evolving World of Healthcare
- Where are the Tech IPOs?
- Impact Investing: What is it and is it Effective?
- The Evolution of the Angel Investor
This forum will also offer an invaluable opportunity for professionals, academics, students and alumni to explore the challenging issues surrounding private equity and venture capital, as well as to network with other industry professionals.

Golden Torizo Statue
Edit Page Last Edit: 2 years 10 months ago
The Golden Torizo is much stronger than the one guarding Morph Ball Bombs, but the fight is still pretty similar. One big difference is that this one will sidestep to completely dodge missiles, and will catch super missiles to throw them back at you. It's possible to hit it with a super missiles while it's holding another one, but charged beam shots are the best choice for this fight anyway.
Damaging it will make it slowly revert to the same coloration as the first one. Eventually it will start hatching creatures that fly out at you, but they're pretty much harmless; just keep pummeling it with your beam until it dies.

The California Department of Education will develop new history and social science lessons for K-12 classes after Gov. Jerry Brown signed new legislation authorizing the move Saturday.
The curriculum currently being used in California public schools was developed in 1998. Existing law prohibited the California Board of Education from developing new history and social-science coursework until
"It is a serious shortcoming that our basic instructional materials are so outdated," Hancock said. "California textbooks don't even mention the 9/11 tragedy or the election of Barack Obama to the presidency.
"We have an obligation to students and teachers to ensure that California schools will have materials that reflect the contributions of the many diverse cultural and religious groups in this country, as well as events in the second decade of this century - and not just those prior to 1998," Hancock said.

The DB2 Database System
This invention relates to the use of database software such as the well-known DATABASE 2 database software distributed by IBM Corporation, commonly referred to colloquially in the art as "DB2." As is well known to those of ordinary skill, generally speaking DB2 operates as a subsystem in a computer system that itself is operating under the IBM MVS operating system software. More specifically, the invention relates to a method by which a user of a DB2 application can dynamically add and remove DB2 active logs without affecting the availability of the database system or of DB2 applications.
Generally speaking DB2 operates as a subsystem in a computer system that itself is operating under the IBM MVS operating system software. A given MVS system may have more than one DB2 subsystem operational at any particular time. In this specification the term "DB2" is used to refer to an arbitrary single DB2subsystem.
FIG. 1 illustrates, in greatly simplified form, one typical type of configuration in which DB2 is used. In such a configuration, DB2 interacts with the well-known IBM Time Sharing Option (TSO) software. An application program labeled "DB2 APPLICATION" indirectly makes use of DB2-provided services, via calls to TSO, to read from and write to data storage labeled DASD. Such an application program is commonly referred to generically in this context as a "DB2 application." The DB2 application typically communicates indirectly with a user via calls to communications management software such as, e.g., the well-known IBM Virtual Terminal Access Method (VTAM) software.
DB2 Logs
As is well-known to those of ordinary skill, DB2 maintains a number of "logs." A log is a linear data set (LDS) structured to conform to IBM's Virtual Storage Access Method (VSAM). In essence, a log serves as something like a logbook or chronological journal of DB2's activity. Generally speaking, when DB2 updates data in a DB2 object, the type of update event or transaction is recorded in a log along with both the old and new data. As a result, in certain circumstances involving corruption of dam, e.g., abnormal termination of a DB2 application, DB2 can attempt to use the logged information to recover as much of the corrupted data as possible. Such transactions are recorded initially in an "active log" in memory for quick access. The DB2 active log is the prime source of recovered data that has not been archived.
DB2 utilizes a fixed number of active logs, with the number and size of the logs being set at DB2 initialization time. DB2 may be configured by the database administrator (DBA) to maintain two or more active logs in memory, of which one is always the "current active log."
As illustrated in simplified form in FIG. 3, DB2 maintains the active logs as, in effect, a single logically infinite log by performing a round-robin type of operation, switching from a full active log (e.g., ACT3 if FIG. 3) to the least recently used active log data set (e.g., ACT1) and overwriting it. This normally does not cause a problem because the active-log information in the least recently used active log data set is ordinarily copied off to an archive log prior to being selected for overwriting. At the database administrator's option, the DB2 subsystem can be operated in "dual active log chain" mode. In that mode, for redundancy purposes the active log chain is kept in duplicate copies, referred to as copy 1 and copy 2.
During operation DB2 refers to a bootstrap data set (BSDS), illustrated in simplified form in FIG. 4, to determine what active logs are available. The bootstrap data set is a VSAM key sequence data set that in many respects functions as a restart data set; that is, the BSDS provides a storage area in which DB2 keeps track of its own current status in case it must be restarted (e.g., after a system failure).
The BSDS includes an active log copy 1 record; if the DB2 subsystem was started in dual active log mode the BSDS also includes an active log copy 2 record. Each of the active log copy 1 and 2 records comprise a 4K page of storage, which effectively limits the size of the active log chain because when the available space in the BSDS record is exhausted, no more active logs can be added. The BSDS also includes records in which DB2 keeps track of its archive data sets. Whenever DB2adds, or archives, an active log, it updates the active log record (including the active log's relative byte address or RBA, assigned by DB2) in the BSDS.
In FIG. 4, a BSDS key record includes an identifying code shown in the Figure as 04000001, followed by (i) the respective record keys of the active log copy 1 and copy 2 records, and (ii) the respective record keys of the archive log copy 1 and copy 2 records. Each of the active log copy 1 and copy 2 records includes the record's key followed by header information labeled HDR and by a series of fields labeled LOGe1, LOGe2, etc., each representing an active log and its status information such as its data set name, status flags (described in more detail below), RBA ranges, timestamps, etc.
As illustrated in simplified form in FIG. 5, DB2 also utilizes a log management control block (LMB) in managing its active logs. The LMB has "chained" to it (i.e., the LMB includes pointers to the head of a chain of) two or more control blocks LDSD in a circular chain, with each LDSD representing an active log data set labeled LOG. The LMB also includes a pointer to the current active log. In addition (but not shown in FIG. 5), the LMB includes a pointer ALW1, pointing to an in-memory (cached) copy of the COPY 1 BSDS record, and if in dual active log mode, a pointer ALW2 pointing to a similar cached copy of the COPY 2 BSDS record.
Each LDSD control block includes a status code for the associated log. The status codes include STOPPED (indicating that the log may not be used for some reason), NEW (indicating that the log may be used to write transaction records but that no such writing has yet occurred), TRUNCATED (used to indicate that only part of the log includes transaction data, e.g., because the log's duplicate or counterpart in a dual active log chain has a smaller storage capacity than the log), and REUSABLE (indicating that the contents of the log have been copied to permanent or archived storage and thus that the memory used for the log can be overwritten if necessary).
Active logs are always open and available to DB2 while DB2 is active. DB2writes transaction records to and reads transaction records from these logs on-line. Each active log is shared by all DB2 threads executing under that DB2 subsystem; more precisely, DB2 writes information for all associated DB2 threads to the current active log.
When no more storage is available in the current active log (e.g., because all storage in the current active log has been used up in writing transaction records), DB2switches to use the next active log in the chain. DB2 updates accordingly the LMB pointer to indicate that the next active log is now the current active log. DB2 also copies the contents of the former current active log to archival storage and sets the REUSABLE status code in the LDSD for that log. Log switching is also recorded by DB2 in the BSDS.
The Problem of Fixed DB2 Active Log Capacity
In environments where computer-system and application-program availability is a prime concern, it is normally desirable to have enough active log space to perform timely recovery. When a new DB2 application is brought up, for example, it can sometimes be difficult to predict how many insertions, deletions, and updates may occur in the data associated with that application. That in turn makes it difficult to predict the net additional active log requirements. If data compression is used in a DB2 application, it can be even harder to predict active log requirements. Data compression causes each row (record) to be treated as a variable-length row; that means that any change taking place in a column (field) will be logged as well as all dam to the end of the row in question. Moreover, although the current generation of DASD devices is generally regarded as quite reliable, and although DB2 has the ability to use dual active logs for redundancy, I/O errors can still pose problems of downtime or concern about the availability of DB2.
One long-recognized problem with DB2 is that neither the number nor size of the active DB2 logs can be increased or decreased dynamically. Thus, tuning of the active logs is not feasible without bringing down DB2 (i.e., terminating the execution of DB2), changing the parameters defining the active log number and size, and bringing DB2 back up. The process of bringing DB2 down for the purpose of making parameter changes, then bringing it back up again, is sometimes referred to as "cycling" DB2. Cycling of DB2 frequently results in serious inconvenience to users of DB2 because bringing down DB2 necessarily causes an outage (i.e., unavailability) of all application programs that use DB2. Thus, data bases supported by those application programs become unavailable to users for the duration of the outage.
A related problem is associated with correcting I/O errors on-line. DB2 marks any bad active log associated with such an error as STOPped; correcting the error may require cycling DB2, especially if the STOPped log is the only active log remaining.
Furthermore, if DB2 must recover corrupted data (e.g., if a table space becomes corrupted), the recovery process generally proceeds much faster if it utilizes an active log as opposed to an archive log. If a database administrator installs ("brings up") a new DB2 application, a situation may occur in which the amount of active log space is suboptimal, possibly resulting in degraded performance and recoverability.
A long-felt need has thus existed among database administrators for the capability of dynamically adjusting the active log parameters of DB2 without cycling DB2.
In a novel method of dynamically adding or removing active logs in a DB2subsystem without the necessity of cycling DB2, a set of control blocks emulating certain DB2 control blocks is constructed.
In adding an active log, a call to a DB2 module is made to allocate the new active log data set and crate a new LDSD control block for the new active log data set. The NEW and REUSABLE status flags are set in the new LDSD control block, initialization of the new LDSD control block is completed, and the new LDSD control block is added to the LDSD chain off the LMB. The BSDS record(s) and the cached portions of the BSDS information are updated to reflect the addition of the new active log.
In removing an active log, the LDSD of the active log is removed from the LDSD chain off the LMB and an attempt is made to deallocate the active log data set via a call to a DB2 module. If the deallocation attempt is unsuccessful, the active log's LDSD is reinserted in the LDSD chain; if the attempt is successful the BSDS and the cached portions of the BSDS information are updated to reflect the removal of the active log.
FIG. 1 is a block diagram showing in greatly simplified form the relationship between DB2 and a DB2 application program. FIG. 2 is a similar block diagram in which a computer program in accordance with the invention is added in to that relationship.
FIGS. 3, 4, and 5 depict prior-art aspects of DB2 as described in more detail above.
FIG. 6 is a flow chart of particular steps used in building a data structure to emulate certain control blocks used by DB2.
FIGS. 7 and 8 are flow charts in simplified form of steps executed in an illustrative implementation of two specific methods in accordance with the invention.
One illustrative embodiment of a method in accordance with the invention is described below as it might be implemented in a computer program (referred to here for convenience as "NEWPROG"). An actual implementation of such a program might be executable on, e.g., an IBM System 370-compatible machine or equivalent running IBM OS/VS SP2 (MVS/XA), SP3 or SP4 (MVS/ESA) and IBM Database 2 (DB2) version 1.3 or later, or on one or more other suitable computer systems. For purposes of further illustration, the microfiche appendix sets out selected extracts of source code from an actual software package owned and distributed under license by the assignee under the trademark OPERTUNE.
In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual implementation (as in any software development project), numerous programming decisions must be made to achieve the developers' specific goals and subgoals (e.g., compliance with system- and business-related constraints), which will vary from one implementation to another. Moreover, attention will necessarily be paid to, e.g., proper serialization to handle concurrent events. It will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of MVS system program development for those of ordinary skill having the benefit of this disclosure.
When invoked by a user such as a DB2 database administrator, NEWPROG carries out the method of adding or removing active logs, as requested by the database administrator, by issuing a request to the MVS operating system that a main routine be scheduled for execution under an SRB (service request block). That main routine performs or invokes performance of the functions described below.
Initialization: Building a Model of the DB2 Environment
As illustrated in FIG. 6, NEWPROG performs as a prelude a series of definition and environment-value lookup steps (each of which by itself is conventional), then builds a data structure to emulate certain control blocks used by DB2 to store parameters about the thread. While some of these control blocks are documented in various DB2 information manuals, others are undocumented and had to be determined empirically. The address of the control block SCOM for the DB2 environment being modeled is used as an input; the address of a control block referred to as EB-- X, emulating the DB2 control block of the same name for the thread in question, is returned as an output.
Block 6.2: It has been found that different releases of DB2 may make use of CCB and ROB control blocks that are of the same name and general structure but of different lengths. In particular, DB2 releases prior to 2.3 use CCB and ROB control blocks of different lengths than those of release 2.3. Whether the DB2 installation is release 2.3 is tested by a conventional examination of the operating system's DB2 installation information in the DECP control block. Variables containing the lengths of DB2's CCB and ROB control blocks are initialized to the appropriate values depending on whether the DB2 release is 2.3 or earlier.
Block 6.5: If a Program Temporary Fix (PTF) is in effect, the EB and ACE control blocks in DB2 will have different lengths than otherwise. Accordingly, NEWPROG determines whether a PTF is in effect by conventional examination of operating system information, and sets a flag iPTF if so. If the iPTF flag is set, then respective variables defining the length of the EB and ACE control blocks are set to respective Large values, else to respective Small values.
It has been determined empirically that DB2 apparently maintains unique identifying codes for various control blocks such as the ACE control block. Most of those codes may be determined conveniently by "running the chains" of the DB2 control blocks (referring to the documentation of those control blocks in the aforementioned IBM publications) to locate the control block of interest, then calling a dump analysis package such as IPCS distributed by IBM, or the DB2 dump formatting utility such as the program DSNWDMP provided with DB2, to examine the control block and thereby obtain its identifying code.
Block 6.10: An ACE-- X control block, for emulating DB2's ACE control block of the same name, is created and initialized by obtaining a segment of free storage (the size or length of which was determined in the steps beginning at block 6.2) with a GETMAIN statement. That storage is obtained from subpool 241; it may be either above or below the 24-bit addressable storage line, and must be in Key 7 storage. Initialization of the ACE-- X control block includes determining whether the EB control block for the DB2 installation will have a structure reflecting a DB2 PTF release, by checking whether the iPTF flag is set. Initialization also includes writing (i) the length of the ACE-- X control block and (ii) the unique DB2 identifying code of the ACE control block being emulated, into the appropriate locations in the ACE-- X control block. Later in the initialization, the address of the EB-- X control block will also be recorded in the ACE-- X control block.
Block 6.11: Because the ACE control block in DB2 includes the EB control block, initialization of the ACE-- X control block also includes setting up an EB-- X control block, as part of the ACE-- X control block, to emulate the EB control block of DB2. The EB-- X control block is initialized by writing to that control block (i) the length of the EB-- X, as determined above, (ii) the DB2 identifying code of the EB, (iii) a pointer to the DB2 control block RMVT, (iv) the EB flag A, (v) the EB flag D, (vi) the EB's home ASCE, and (vii) a flag indicating whether the routine running at any particular time is running in the DB2 master address space or in the DB2 data base's address space.
Block 6.12: Similar steps are performed to obtain and initialize a control block ROB-- X. Again, a GETMAIN is performed to obtain a block of free Key 7 storage from subpool 241; the length of the block is the variable iROBLEN, determined in block 6.2 as described above. The address of this block of storage, i.e., the new ROB-- X control block, is recorded in the ACE-- X control block. The ROB-- X control block is initialized by recording in it (i) the unique DB2 identifying code of the ROB, (ii) the length of the ROB-- X, and (iii) a pointer back to the ACE-- X control block. Thus, a chain of pointers has been created from the ACE-- X control block to the EB-- X control block to the ROB-- X control block and back to the ACE-- X control block.
Block 6.13: A control block CCB-- X is created and initialized in similar fashion. Again, a GETMAIN is performed to obtain a block of free Key 7 storage from subpool 241; the length of the block is the the variable iCCBLEN, determined as described above. The address of this block of storage, i.e., the new CCB-- X control block, is recorded in the ACE-- X control block. The CCB-- X control block is initialized by recording in it (i) the unique DB2 identifying code of the CCB, (ii) the length of the CCB-- X, and (iii) in the field corresponding to the user identification field of DB2's CCB control block, an identifier indicating that the user is the Install SYSADM (i.e., the installation system administrator, who by definition has unlimited access privileges in DB2).
Block 6.14: A control block XSB-- X, emulating the MVS control block of the same name, is obtained by executing a GETMAIN to obtain a block of free Key 7 storage in subpool 241. The XSB is used by MVS to handle SRBs that are suspended and then later resumed. Storage for XSB-- X may be taken from below the 16-meg line to take into account the possibility that some older versions of MVS's SRB dispatcher may assume that the XSB is located in this region of storage. The block of storage for the XSB-- X may have a fixed length (i.e., the size of the MVS control block XSB), and therefore the required size of the block need not be determined as it was for the ACE, EB, ROB, and CCB.
Block 6.15: Another GETMAIN is used to obtain storage for an SRB status save area control block STSV-- X in Key 7 storage, subpool 241, of fixed length, below the 16-meg line. The STSV-- X is initialized to include a pointer to the XSB-- X control block; in addition, the address of the STSV-- X is saved as a pointer in the EB-- X control block.
Block 6.16: A stack storage block SKB-- X, to emulate the DB2 control block of the same name, is obtained and initialized. The size of the SKB-- X is dependent on whether the release of DB2 is prior to release 2.20. A GETMAIN is issued to obtain a block of free Key 7 storage in subpool 241 below the 16-meg line. The SKB-- X is initialized by recording in it (i) the unique DB2 identifying code of the SKB, (ii) the length of the SKB, (iii) a pointer to the EB-- X control block, (iv) a "bottom" field indicating the last byte of the SKB-- X, (v) an "available" field pointing to an area in the SKB-- X that is available for use by application programs, (vi) a pointer to a current segment CSEG that points to itself, and (vii) a counter field that is initialized to a value of 1.
A pointer is returned to the newly built EB-- X control block. An emulation or model environment has thus been created wherein the EB-- X points to the ROB-- X which in turn points to the ACE-- X which points back to the EB-- X. The EB-- X control block also points to the STSV-- X which points to the XSB-- X and to the EB-- X which in turn points to the SKB-- X. This environment provides a standard set of control blocks that are useful in calling various specific DB2 routines for execution as discussed below (other control blocks may be built on an as-needed basis).
Adding an Active Log
Referring to FIG. 7, NEWPROG checks to ensure that sufficient storage in the BSDS active log record(s) is available to add an active log; if not, an error message is returned. NEWPROG then attempts to locate a TCB in the DB2 master address space and schedules an IRB to run under that TCB and carry out essentially all of the rest of the functions described below.
In block 7.3, NEWPROG invokes the DB2 module DSNJDS01 to allocate the new active log data set. That module returns a pointer to an LDSD, partially initialized to describe the new data set. At block 7.4, NEWPROG adds to the new LDSD the status flags NEW and REUSABLE and finishes initializing the LDSD in accordance with DB2's documented standards. If the user specifies that the active log is to be initialized to be like an existing archive data set, NEWPROG tailors the initialization appropriately.
At block 7.5, NEWPROG obtains DB2's LMB LOG WRITE latch to serialize access to the LDSD chain (actually to both LDSD chains), thus preventing DB2 from making changes o:f its own with unpredictable results. At block 7.6 NEWPROG then adds the LDSD into the chain off the LMB by overwriting pointers to "splice in" the new LDSD. If the user specifies that the new LDSD is to be added in at a specific position in the chain, NEWPROG does so. On the other hand, if the user specifies that the active log is to be initialized to be like an existing archive data set (which NEWPROG treats as mutually exclusive from adding in the LDSD at a specified position, because the archived data set will have its own RBA range which means that the new active log's RBA sequencing must be kept consistent), NEWPROG computes the location at which the new LDSD is to be added to the chain. In either case, NEWPROG determines where the new active log will be added to the BSDS; based on that, NEWPROG determines where to add the new LDSD to the chain.
At block 7.7, NEWPROG updates the BSDS to reflect the new active log, first obtaining DB2's BSDS ACCESS latch to keep DB2 from making unpredictable changes during this process. If DB2 is in dual-BSDS mode (determined by the database administrator at DB2 startup time), NEWPROG makes corresponding changes to both BSDSs. The required operations are, in essence, those performed by the prior-art DB2 batch utility for adding an active log when DB2 is down, i.e., adding an entry to either the active log copy 1 or copy 2 record and registering a new active log in the BSDS.
At block 7.8, NEWPROG updates the cached information pointed to by the ALW1 and ALW2 information in the LMB to reflect the addition of the new active log. Finally, at block 7.9, NEWPROG releases the latches that were obtained as described above.
During the active-log addition process, NEWPROG keeps track of its status on an on-going basis; thus, if any part of the process goes awry, the changes made can be backed out and an appropriate report issued to the requesting user.
In a variation on the active log-addition process, if the DB2 subsystem was started in single active log chain mode, the user can request that NEWPROG switch the subsystem to dual active log chain mode, and vice versa.
In another variation, if the user requests that an active log be added for both copy 1 and copy 2, but the DB2 subsystem is running in single active log chain mode, NEWPROG allocates an LDSD for the copy 2 record and updates the information in the BSDS accordingly (so that the next time DB2 is cycled it restarts in dual active log chain mode), but does not alter the LMB chain.
Removing an Active Log
In response to a user request, NEWPROG removes active logs so long as there will be at least two active logs remaining (and provided that the user is not attempting to remove the current active log). The steps taken to remove an active log are in many ways the mirror image of those taken to add an active log.
Referring to FIG. 8, at block 8.2 NEWPROG obtains DB2's LMB LOG WRITE latch to serialize access to the LDSD chain (actually to both LDSD chains), thus preventing DB2 from making changes of its own with unpredictable results. At block 8.3 NEWPROG then removes the LDSD of the active log being removed from the chain off the LMB by overwriting pointers as described above.
At block 8.4, NEWPROG invokes the DB2 module DSNJDS01 with a request that the active log data set in question be deallocated. If the DB2 subsystem is in dual active log chain mode, active log copy 1 or copy 2 or both are removed in this manner. At block 8.5, if this deallocation step is unsuccessful NEWPROG chains the active log back in as described above and returns an error message to the requesting user.
At block 8.9, if the deallocation is successful, NEWPROG obtains DB2's BSDS ACCESS latch and edits the BSDS to eliminate the entries for the active log being removed. One way of doing so is to search the BSDS to find the target active log entry, zero it out, and compact the chain by block-copying everything below the target entry to move it one up, then zeroing out the bottom.
At block 8.10, NEWPROG refreshes the cached in-memory copy of the BSDS record pointed to by ALW1 (and ALW2 if in dual active log chain mode) to reflect the removal of the active log, then releases the latches at block 8.11.
It will be appreciated by those of ordinary skill having the benefit of this disclosure that numerous variations from the foregoing illustration will be possible without departing from the inventive concept described herein. Accordingly, it is the claims set forth below, and not merely the foregoing illustration, which are intended to define the exclusive rights claimed in this application.
The following general-purpose glossary is provided solely as a convenient aid to understanding for readers who may not be familiar with particular terms of art. The inclusion of a term in this Glossary should not be interpreted as necessarily being completely definitive of the meaning of the term, nor as necessarily limiting or expanding the scope of any claim.
16-megabyte line: Term used in some computer systems to denote the upper boundary of the first 16 megabytes of main memory. Sometimes referred to as the 24-bit line (because a sequence of 24 bits can be arranged in on-off combinations to define individual addresses for 16 megabytes of main memory locations).
24-bit line: See 16-megabyte line.
-- X: When applied to a name as a suffix, used to identify a control block, a routine, etc., created to emulate (partially or completely) a corresponding control block, routine, etc., of DB2. For example, ACE-- X is used to denote a control block created to emulate the DB2 control block ACE.
ACE: A DB2 control block.
Address: The "location" of, e.g., a specific variable in memory, a specific input/output device on an input/output bus, etc. Typically, the term "location" actually refers to a unique identifier assigned to the variable, device, etc.; operations such as "writing" data to be stored in a particular portion of memory are accomplished by "broadcasting" the data to all portions of memory along with the identifier (address) of the memory portion that should actually receive and store the data.
Address space: An MVS term used to identify a collection of tasks used to perform a set of functions. (Primary address space, secondary address space)
Address space control block: An MVS control block encoding information about, and used to represent, an address space.
Ancestor chain: A chain of TCBs, each created by the previous TCB in the chain. As a hypothetical example, the ancestor chain of TCB-3 might be as follows: TCB-1 creates TCB-2, which in turn creates TCB-3.
API: Acronym for Application Program Interface, in essence a language or set of communications conventions by which an application program and an operating system can transmit work requests, status reports, etc., to each other.
ASCB: Acronym for address space control block.
ASCE: A DB2 control block. An ASCE exists for each address space that has a thread to DB2.
Asynchronous: If a first "agent" such as a process, a machine, etc., issues a request for a second agent to perform some work, the first agent might either suspend its own operations after issuing the request until it receives a report back from the second agent; this is commonly referred to as synchronous processing. Alternatively, the first agent might continue its own operations after issuing the request, often on the assumption that it will be notified when the second agent has completed its work; this is commonly referred to as asynchronous processing.
CCB: A DB2 control block identifying an individual thread.
Code: (a) Instructions for execution by a processor in a computer system. See also Source code, Executable code. (b) In DB2, a unique two-byte identifier assigned to a DB2 control block.
Computer program: A set of statements or instructions used directly or indirectly in a computer in order to bring about a certain result. Depending on the context, a computer program may comprise either or both of source code and executable code.
Control block: A data structure created and/or utilized by a computer program to keep track of information during the program's execution. A control block is roughly analogous to a set of working notes kept by the program. Depending on its design, a program may create, use, and/or discard several control blocks during its execution. See also Structure.
DB2: A common nickname or acronym for the Database 2 software system distributed by International Business Machines Corporation (IBM), extensively documented in various IBM publications such as [DB2DIAG].
EB: Acronym for "event block, " a DB2 control block used to track a unit of work in DB2.
EUT: See Enable-Unlocked-Task.
Enable-Unlocked-Task: A task which has no processing restrictions.
Executable code: A series of one or more instructions executable after suitable processing by a computer or other programmable machine, without compilation or assembly.
Field: A defined part of a data record or data structure; roughly equivalent to a variable. For example, in a data base of employee information, the field "EmployeeName" in the data record for a given employee would be set to that employee's name. See also Control Block, Structure, Variable.
Flag: Typically, a true-false indicator as to some specified condition, or an "option A/option B" indicator.
FRR: See functional recovery routine.
Functional recovery routine: In the IBM MVS operating system, an error handling routine which can be used to recover from and/or obtain information about unanticipated program execution errors.
Initialize: (a) With respect to a variable, setting the variable to a specified value; (b) with respect to a routine, establishing initial conditions for execution of the routine.
INSTALL SYSADM: Used to denote DB2 installation system administrator; signifies the highest level of user/operator privilege in a DB2 installation.
Key 7 storage: Memory or other storage in a computer system whose contents can be altered only if the requestor possesses the appropriate "key," in this case Key 7.
Latch: In DB2, a flag or token used to serialize access to a shared resource. A DB2 thread that has been given exclusive access to such a resource is said to "hold the latch" for that resource. Associated with each thread is an EBLTCHLD flag word in storage that is used as a bit map of latches held by the thread.
Local lock: In the IBM MVS operating system, the lock is a mechanism to serialize the use of a particular shared resource. A call to the MVS function SETLOCK by a process causes MVS to attempt to obtain access to the resource for the process. If the resource is available, then the requesting process is "given the lock." If the resource is not available, i.e., if another process already has the lock, then the requesting process is suspended until the other process gives up the lock, indicating that its use of the shared resource is complete for the time being.
Maintenance release: A release of a computer program or software system that corrects actual problems with the program or system or that provides code for handling potential problems, typically problems discovered since the issuance of the previous release. Maintenance releases sometimes include additional capability or functionality for the computer program. See also PTF, Release.
Module: A portion of a computer program; sometimes referred to as a routine or a subroutine depending on the context.
MVS: IBM's MVS operating system, extensively documented in various IBM publications such as [MVSXA].
Operating system program: A computer program that manages some or all of a computer system and its hardware.
Pointer: A variable whose value is set to the address of, e.g., a memory location. For example, in some situations a particular field in a control block might be defined to be a pointer to another control block. A useful general introduction to pointers can be found in Chapter 5 of [K&R].
Primary address space: The default address space in which access to data and instructions is to be performed.
Processor system: A central processing unit (CPU) and one or more co-processors (e.g., math or graphics co-processors) associated with the CPU.
PTF: Acronym for "Program Temporary Fix," typically a computer program maintenance release that is not given a separate release number. See also Maintenance Release.
Record: In a database, a single set of formatted data. For example, in a database of employee information, a record might constitute all information about a given employee that is kept in that database. Data in a record is commonly divided into fields. See also Field, Structure.
Release: In the software industry, the term "release" typically refers to a (usually numbered) version of a computer program or software system distributed to licensees. Release numbering often takes the form "major.minor," e.g., release 1.0 signifies the first major release of a program that is distributed to licensees, while release 1.1 signifies the first minor release of that first major release. See also Maintenance release.
RMVT: A DB2 control block.
ROB: A DB2 control block.
Routine: A portion of a computer program; sometimes referred to as a subroutine or a module depending on the context.
Running the chains: Colloquial expression used to describe following a chain of pointers to arrive at an Nth data structure, i.e., examining a first data structure to obtain the address of a second data structure; examining the second data structure to obtain the address of a third data structure; and so forth.
SCOM: A DB2 control block.
Secondary address space: An address space used by some CPU instructions to access data.
SETLOCK: An MVS macro instruction; see "local lock."
Source code: A series of instructions or statements in an English-like high-level computer language such as FORTRAN, C, PASCAL, or LISP, or in a relatively low-level language such as the assembly language for a particular processor. Source code is normally readily readable by humans trained in the particular computer language in question. It is normally transformed by an interpreter or compiler into machine-readable executable code for actual use on a computer.
SRB: Acronym for Service Request Block. In the MVS operating system, one way in which an application program can request that work be performed by MVS is to create an SRB--a formatted control block defining the work request in conformance with the MVS API--and to pass the address of the SRB to MVS with a request to perform the work specified in the SRB. See also API, TCB.
Status Save Area: An MVS control block.
Structure: As defined in [K&R], "a collection of one or more variables, possibly of different types, grouped together under a single name for convenient handling. (Structures are called `records` in some languages, notably Pascal.)" A useful introductory discussion of structures is set out in [K&R] chapter 6. See also Control Block.
Subpool: An identification code used to group or associate different blocks of storage.
Subroutine: A portion of a computer program; sometimes referred to as a routine or a module depending on the context.
Synchronous: See "asynchronous."
SYSADM: Acronym for System Administrator.
System variable: A variable defined and maintained by an operating system program.
TCB: Acronym for Task Control Block, an MVS control block.
Thread: In DB2, an information connection or attachment between DB2 and another MVS subsystem utilizing DB2's services. DB2 keeps track of each thread through the use of various control blocks such as the ACE.
Timeout: Temporary or permanent cessation of a process, subroutine, etc., upon the occurrence of an event such as the passage of a specified period of time, the performance of a certain number of repetitions of a process, and the like.
Variable: A location in memory associated with a particular identifier and set to a particular value by a computer program, e.g., by an application program or an operating-system program. For example, a computer program for processing employee payroll information might define a variable EmployeeName that, at a particular time, is set to the value "Smith."

Even the bright seaside village of Molena Point has been hit hard by the economic downturn, bringing a rash of foreclosures in which many residents are abandoning their family pets. While feline P. I. Joe Grey's human friends join together to care for the starving cats, a fire leaves a twelve-year-old boy homeless. The body of his alcoholic guardian is discovered in the smoldering ruins, causing Joe to wonder if escape was really impossible for the elderly woman or if something more sinisteroccurred.
Meanwhile, Debbie Kraft descends uninvited on the Damens' home with her two children, claiming that her ex-husband has left her with no money and nowhere else to go. But when Joe learns that the victim of the fire was Debbie's estranged mother and that Debbie is not broke at all but carrying plenty of cash, his fur is on end with suspicion.
As Debbie's abandoned tomcat follows her all the way down the coast from Oregon with his own clues to add to the mix, Joe learns that Debbie's Realtor ex-husband may be involved in a number of intricate real estate scams. Furthermore, his sales partner may be missing, and while Joe and his pals prowl through the dead woman's house, they discover that her reclusive neighbor has disappeared as well.
But it's not until Debbie's tomcat arrives that Joe and his feline detective pals find the biggest clue of all: a grave that the cops have missed. And as the pieces of the puzzle begin to come together, tortoiseshell Kit sees her own dreams coming true in the handsome new cat with whom she might share her life's adventures.
