9.3.4 CICS GDG Generation Program (CICGDGGN)

The utility program CICGDGGN defines the generation data
group (GDG) for storing the DETAIL.CICCSU01 (CICS User
Activity) file on tape as well as the IBM 110 STATISTICS
records.

The creation of the DETAIL.CICCSU01 file on tape is
controlled via the TAPECSU keyword in CICOPS.  The creation
of the STATISTICS records on tape is controlled via the
STATCOPY keyword in CICOPS.

TAPECSU

By default, the GDG has 7 generations, and is named
tapeprefix.tMICS.DETAIL.CICCSU. Tapeprefix is the tape
prefix that you have defined in prefix.MICS.PARMS(JCLDEF)
and tMICS is the MICSLEVEL associated with the tapeprefix
keyword.  At this time, the only CA MICS file written to tape
during the DAILY update is the DETAIL.CICCSU01 file.

To customize the specifications of the DETAIL.CICCSU01 file
such as the number of generations, see sections
7.3.2.12.2/3/4 of this guide.

For more information on writing DETAIL.CICCSU01 to tape
during the CA MICS daily update, refer to section 7.3.2 of
this guide for a discussion of prefix.MICS.PARMS(CICOPS),
section 10.1.4 for the comprehensive checklist to activate
the DETAIL CICCSU file on tape, and section 10.2.3 for
information on the USRTCSU exit, which enables you to limit
the amount of data written to the DETAIL.CICCSU tape file.

STATCOPY

For information on writing the IBM 110 STATISTICS records to
tape, see section 7.3.2.4.  For information on the use of the
USRSTAT exit, see section 10.2.3.
