DFSDF
Specifies the 3-character suffix of the DFSDFxxx member of the IMS™ PROCLIB data set that contains the settings and attributes of the IMS catalog. The specified member is used when these three conditions are met:
  • The ZDT/IMS function runs in DLI mode.
  • IMS manages the ACBs (ACBMGMT=CATALOG).
  • The IMS Catalog Definition exit routine (DFS3CDX0) is not used.

Ensure that the CATALOG section of the DFSDFxxx member specifies CATALOG=Y, ACBMGMT=CATALOG and the alias name for the IMS catalog and, if the IMS catalog database is unregistered, that the DATABASE section of the DFSDFxxx member specifies the IMS catalog database names.

This parameter is optional. If it is not specified on the HFM1POPI macro statement, ZDT/IMS uses either the value specified on the HFM1POPD macro statement (if specified on that statement), or 000 (otherwise).

The user cannot override the value you specify for this parameter.
