CICS CEMT I DSN - DSN NOT IN CSD REPORT

Tom Walker · Posted: Mon Sep 14, 2009 9:26 pm

The CEMT I DSN command displays data set names that are not found in the CSD report. To produce the CSD report, I executed the DFHCSDUP program using the groups listed in the SIT member for the CICS started task. There were four groups listed. For each group in the report job I used the command: LIST LIST(groupname) OBJECTS. The report shows many of the data set names found in the CEMT I DSN(*) display, but not all of them. I have never encountered this. I have double checked by CSD data set name and the group names to be sure I am using the correct ones. Where are these new DSN's coming from?

Have you check the CICS JCL? IIRC, you can override the DSNAME at run time by specifying the DD name and DSNAME for the file which will use the provided value, not the CSD value.

All of the DSN's not in the CSD report are BDAM files. None are VSAM files. They do not appear in the running task so I do not see how they could be overrides from job control language. I am wondering if, in an MRO environment, these files are defined in another group not directly associated with my region. Just wondering. I am not a CICS techie.

I viewed the started task for the CICS region. This is currently running and I did not see anything to match the FCT names nor the data set names of the BDAM files that appear in the CEMT I DSN(*) display for that region. Would this started task not show any overrides? In the SIT input I did find an FCT parm with a comment that says 'contains BDAM entries' so I am researching this parm at present. As for whether I am looking at the TOR or the AOR, I have to research that as I do not yet know how to determine that. I figure that these BDAM dsn's have to be stored in a file, a table, or some object that is linked to the CICS region.

To answer my own question: BDAM files are defined using the DFHFCT macro and are not part of RDO and are not in the CSD file but are loaded from the DFHFCT library at CICS initialization time. I do not know if there is a tool that will list them from this library.
