Creating the CICS data sets

After you have installed CICS®, and applied any necessary service, you can run the DFHCOMDS, DFHDEFDS, and DFHCMACI jobs to create the CICS data sets.

CICS supports access to the following types of data sets:

Data sets

The data sets created by the jobs described in this section are required by the IVPs described in Running the installation verification procedures.

 

VSAM Data sets and z/OS® 1.3

If you are using z/OS 1.3 or above, read Information APAR II13288.

It reports that the level of DFSMS supplied with z/OS 1.3 has changed the way that index controlintervalsize (CISIZE) is calculated for those VSAM data sets that have index components. As a result, large default CIsizes can be expected, and this can cause open errors during CICS start-up.

This applies to both CICS data sets and your own application data sets.

Job
Function
DFHCOMDS
Deletes and recreates data sets common to all CICS regions.
DFHDEFDS
Deletes and recreates copies of data sets that are used only by one CICS region. You run a separate copy of this job to create the data sets for each CICS region.
DFHCMACI
Deletes and recreates the CICS messages data set, dsindex.DFHCMACD, and loads it with the data from the CICS-supplied file, DFHCMACD, in the hlq.SDFHMSGS target library.
DFH0JCUS
Deletes and recreates the sample applications details data set, dsindex.SAMPLE.DFHCTCUS (and its associated alternate index and path), and loads it with the data from the CICS-supplied file, DFH0DCUS, in the hlq.ADFHAPD2 library.
DFH0JHLP
Deletes and recreates the sample applications help data set, dsindex.SAMPLE.DFHCTHLP, and loads it with the data from the CICS-supplied file, DFH0DHLP, in the hlq.ADFHAPD1 library.

When you ran DFHISTAR, these jobs were tailored to your environment and stored in the library that you specified on the LIB parameter of DFHISTAR (by default, hlq.XDFHINST). If you have not yet run DFHISTAR, you should do so before running any of the CICS post-installation jobs.

You can generate several copies of these jobs by rerunning DFHISTAR, selecting the jobs that you want to copy. To generate new copies of these jobs, edit DFHISTAR to specify new values for the DSINFO and SELECT parameters. Only those jobs that you name by the SELECT parameter are regenerated.
