Creating several copies of the DFHCSD and SYSIN data sets

The CICS-supplied DFHCOMDS job creates one of each of the DFHCSD and SYSIN data sets common to all CICS® regions.

To use separate copies of any of these data sets for each CICS region:
  • Move the statements that define the data set from the DFHCOMDS job to the DFHDEFDS job.
  • Edit the statements in the DFHDEFDS job to specify the symbol &REGNAME for the region qualifier in the name of the data set.

Move and edit the appropriate data set statements before you create copies of the DFHDEFDS job for each CICS region. When you run DFHISTAR to create the new copies of the DFHDEFDS job, it substitutes your values for the CICS region qualifier (&REGNAME) and index (&INDEX) into the data set names.

For example: If you intend using a copy of the DFHCSD data set for each CICS region, copy the job steps DELCSD, DEFCSD, and INITCSD from the DFHCOMDS job to the DFHDEFDS job. Also, add the symbol &REGNAME for the qualifier to the name of the DFHCSD data set to give &DSINDEX.CICS&REGNAME.DFHCSD. If you edit DFHISTAR to select the DFHDEFDS job to be copied, and specify the following DSINFO parameter: 
DSINFO userid.CICSTS54.CICS H3P060 3390 IDA .
when you run the DFHDEFDS job, it creates the DFHCSD data set called userid.CICSTS54.CICS.CICSIDA.DFHCSD for the CICS region identified by the qualifier IDA. If you change the SELECT and DSINFO parameters of DFHISTAR, to specify an appropriate new job name and qualifier for another CICS region, you can create several copies of the DFHDEFDS job to create DFHCSD and SYSIN data sets for each CICS region.
