Chapter 1. Introducing transaction af finities This chapter provides a brief introduction to the concept of transaction aff inities and the associated CICS programming techniques, and highlights the significance of transaction aff inities in a dynamic routing (known in previous releases of CICS as dynamic transaction routing) environment. For more[...]

CICS T ransaction Server for OS/390 Release 3 introduces extended dynamic routing facilities, that allow the dynamic routing of: v T ransactions initiated at a terminal v EXEC CICS ST ART requests that are associated with a terminal v EXEC CICS ST ART requests that are not associated with a terminal v Dynamic program link (DPL) requests that are re[...]

The benefits of dynamic routing Being able to route transactions to target regions dynamically offers many benefits in an online transaction processing (OL TP) system. The user can achieve: v Improved performance v Improved availability v Simplified systems management What does dynamic routing cost? Of course, the CICS-supplied code cannot deter[...]

Note that, if you are dynamically routing non-terminal-related ST ART and DPL requests, you should review your application to determine whether or not the application is suitable for dynamic routing. The T ransaction Affinities Utility cannot detect aff inities in these circumstances. Inter-transaction af finity Inter-transaction aff inity is an af[...]

Userid A group of transactions where all instances of the transactions that are initiated from a terminal and executed on behalf of the same userid must execute in the same target region for the lifetime of the aff inity . The af finity lifetime for userid relations can be pseudoconversation, signon, system, or permanent. Af finity lifetimes The af[...]

Safe programming techniques The programming techniques in the safe category are the use of: v The communication area (COMMAREA) on CICS RETURN commands v A terminal control table user area (TCTUA) optionally available for each terminal defined to CICS v ENQMODEL definitions to give sysplex-wide scope to ENQs and DEQs Unsafe programming techniques[...]

Protecting applications from one another The transaction isolation function offers storage protection between application programs, ensuring that one application does not accidentally overwrite the storage of another . T ransaction isolation ensures that user-key programs 1 execute in their own subspace, with appropriate access to any shared storag[...]

What next? This chapter has briefly summarized the techniques and commands that can cause transaction aff inity . “Chapter 2. Introducing the T ransaction Affinities Utility” on page 9 gives an overview of the T ransaction Af finities Utility , and details of all the commands and command sequences that the T ransaction Aff inities Utility look[...]

The Scanner component The Scanner is a batch utility that scans a load module library to detect those programs in the library that issue EXEC CICS commands that may cause transaction aff inity . It examines the individual object programs looking for patterns matching the argument zero 3 format for the commands in question. The Scanner detects the u[...]

Y ou are recommended to run the Detector on stable CICS regions only . Do not apply maintenance to application programs while the Detector is running. Such maintenance may introduce or remove aff inities, thus rendering collected data inaccurate.

There are two a[...]

The af finity data VSAM files The Detector uses three non-recoverable VSAM KSDS to hold saved aff inity data. Ensure the files are big enough to hold the maximum amount of aff inity data that might be collected. Three are required because of the wide range of key lengths that the different tables have. KSDS files are used because the Detector an[...]

Detector performance The Detector is intended to be run against production CICS regions. However , over the period when the Detector is running, the CICS region suffers a performance degradation (dependent on the workload and number of aff inities) equivalent to the performance impact of vendor monitor products that use the same user exits. The Det[...]

The basic groups are combined because of a CICSPlex SM rule stating that a given tranid may appear only in a single transaction group. It is quite possible that a tranid may appear in more than one basic group, and so these must be combined to form larger groups that satisfy CICSPlex SM. Chapter 2.

Each time the Detector is started, a new data space is created. For help with calculating the likely data space storage requirement, see “Estimating the size of the MVS data space and VSAM files” on page 21. Y ou specify this size on the Detector options screen, CAFF02. Y ou can also specify that data from aff inity data VSAM files (for examp[...]

Note: If there are a large number of data records to be saved, the CAFF screen may be frozen for some appreciable time, until the records have been saved. Y ou may want to stop the Detector when it has detected all affinities. This is indicated by the “Date/time of last change” field changing very infrequently and, if the optional periodic sav[...]

Understanding the af finities The inter-transaction aff inities listed in the report highlight those transactions that have aff inities with other transactions. Understanding the aff inities present in the CICS region enables you to determine which of the them are most pervasive. If you decide that it is worth changing your application programs, it[...]

Detailed af finity analysis Each of the above command scenarios is dealt with below . A description of how the use of the command appears in the T ransaction Affinities Utility Reporter report is given, followed by an assessment of any aff inity problem it causes. However , it would be helpful first to expand on the structure of a CSP segmented ap[...]

There may also be an EQ aff inity group in the report with a resource name of CSMT when CSP serializes writing of information to TD destination CSMT . This does not cause aff inity because each cloned CICS has its own CSMT . GETMAIN SHARED There is a GM aff inity group in the report for each pair of transactions that were observed performing GETMAI[...]

an aff inity of LUNAME and a lifetime of PCONV . The presence of one group rather than a group for each application is actually not important. When dynamic routing, the aff inity still ends when the current pseudoconversation ends, so the effect is exactly the same. It is useful to have applied the PTF for CSP AP AR PN45100, because this adds delet[...]

Chapter 7. Running the Builder This chapter describes how to run the Builder that runs as a batch job to build aff inity transaction groups suitable for input to the CICS system management product, the CICSPlex SM element of CICS T ransaction Server for OS/390 Release 3. This chapter contains the following information: v “Syntax for input to the [...]

Specify the name of the T ransaction Affinities Utility load library where you have installed the Builder program, CAUBLD. v The REPGRPS DD statement Specify the (concatenation of) names of the sequential data sets containing the basic aff inity transaction groups to be input to the Builder . The Builder reads the lines of the input data sets, and [...]

9. If a line comment contains the characters HEADER anywhere in it, it is not treated as a comment and is parsed like any ordinary line in case it is a HEADER statement. Otherwise comment lines are thrown away . 10. The only valid values for AFFINITY are GLOBAL, LUNAME, USERID, and BAPPL. NONE is not allowed. 1 1. Keywords and values (including sur[...]

HEADER statements The HEADER statement is specific to the Builder , and is not a CICSPlex SM statement. It is produced by the Reporter , and is needed by the Builder to create unique transaction group names. The Reporter generates temporary transaction group names (for example, CW .00000001 and TS.00000001) while it is running, and stores these na[...]

Notes: 1. The values of the SA VEDA TE and SA VETIME fields in the HEADER statement give the latest save date and save time from any of the input data sets. (See Figure 1 1 (  1  ) and Figure 12 on page 61.) 2. The combined transaction groups can be input again to the Builder . For example, you may decide to: a. Use the Reporter , then the B[...]

TS commands v The aff inity here is between all transactions that use the same TS queue. It applies to both MAIN and AUXILIARY TS. The match is made on the name of the TS queue. v The aff inity relation can be GLOBAL, BAPPL, LUNAME, or USERID. v Lifetime can be PCONV , LOGON, SIGNON, ACTIVITY , PROCESS,SYSTEM, and PERMANENT . A MAIN queue cannot be[...]

v If the transaction to be ST ART ed is defined as remote or a remote SYSID was specified on the ST ART command so that the command is function shipped to a remote CICS region, no data is collected. v Commands in error are treated in the same way as commands that give a NORMAL response, so data is collected. Scanner dif ferences : Scanner detects[...]

v The LOAD and FREEMAIN protocol applies only to programs defined as RELOAD(YES). Note that HOLD is irrelevant, as CICS Program Control never sees the FREEMAIN, or knows the storage location of the individual task’s copy , and so cannot release the program at task end. This implies that all LOADs must be examined as they are all effectively LOAD[...]

v Lifetime can be PCONV , LOGON, SIGNON, ACTIVITY , PROCESS, SYSTEM, or PERMANENT . The PROTECT option determines whether SYSTEM or PERMANENT would be used. However , the Detector always worsens LOGON and SIGNON to SYSTEM or PERMANENT , because of limitations in the way that this aff inity is detected. The aff inity relation for DELA Y and POST may[...]

Appendix B. Correlating Scanner and Reporter output to source This appendix describes how to match the EXEC CICS command in the Reporter report and/or the Scanner detail report with the actual program source code.

Example 2–VS COBOL II The literal pool in VS COBOL II is part of the CGT . Having calculated the offset from the start of the program, you should subtract the start of the CGT from your calculated offset to get the of fset within the CGT . In the listing, there is an MVC instruction with the argument zero as the source, of the form: MVC D1(L,R1),[...]

For this, the calculations are: Scanner offset = X'7A6' CICS stub length = X'28' Offset of CGT = X'B8' CGT base register = GPR 10 Offset within CGT = X'7A6' - X'28' - X'B8' = X'6C6' = 1734 (decimal) MVC instruction looks like: MVC d(l,r),1734(10) DFHEIV0 PGMLIT AT ... T o determi[...]
