REGCATLG

Specifies whether the IMS™ catalog is registered with Database Recovery Control (DBRC).

Y

The IMS™ catalog is registered with DBRC. The IMS catalog partitions are defined with the DBRC utility (DSPURX00). The catalog partition definitions are stored in the RECON data sets.

N

The IMS™ catalog is not registered with DBRC. The IMS catalog partitions are defined with the IMS catalog partition definition utility (DFS3UCD00). The catalog partition definitions are stored in the catalog partition definition data set.

This parameter is used by FM/IMS functions run in DLI mode when IMS™ management of ACBs is enabled (ACBMGMT=CATALOG) or the database being accessed is the IMS catalog or its secondary index. When REGCATLG=Y, functions use DBRC and database data set names are obtained from the RECON data sets.

This parameter is optional. If it is not specified on the FMN1POPI macro statement, FM/IMS uses either the value on the FMN1POPD macro statement (if one is specified), or Y.

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