Define OPSLOG and Checkpoint VSAM Linear Data Sets

The CA OPS/MVS OPSLOG component and the global variable checkpoint facility require the allocation of unique VSAM linear data sets, which are also called data-in-virtual or DIV data sets. If you are a new user of CA OPS/MVS, then perform the following steps.

To define OPSLOGs and checkpoint VSAM linear data sets

1. Review detailed comments and then tailor member DEFDIV of the hlq.OPS.CNTL file that you created when you downloaded the product from the tape. This member contains the IDCAMS DEFINE commands needed to create a primary OPSLOG DIV data set, an optional secondary or backup OPSLOG DIV data set, and the SYSCHK1 DIV data set, which is used for the global variable checkpoint facility.

   Note: The placement of the DIV data sets should be based on the information in How You Place the DIV Data Sets in this chapter.

   If you are installing CA OPS/MVS on multiple systems, then incorporate either the SMFID or the system name of the system into the data set names as the sample JCL illustrates. This enables you to share a common CA OPS/MVS startup member. For more information, see the section Tailor the Startup Procedures in this chapter.

   The DEFDIV member is tailored.

2. Use the tailored DEFDIV member either as a SYSIN statement in a batch job or execute it as a REXX program under TSO. To execute DEFDIV under TSO, enter the following from ISPF option 6 or at the TSO command prompt:

   EXEC 'SYS1.OPS.CNTL (DEFDIV)'
   

3. If you are not using DFSMS, define these data sets in the master catalog to allow CA OPS/MVS to start under the master subsystem.
4. Note the names that you created for the OPSLOG and SYSCHK1 data sets because you will need to refer to them when you perform the step Tailor the OPSSPA00 REXX Program in this chapter.

   The OPSLOG and checkpoint VSAM linear data sets are defined.
