DBRC


1 DBRC=
2.1! IMS
2.1 Y
2.1 N
DBRC
Specifies whether or not FM/IMS functions use Database Recovery Control (DBRC) when running in DLI mode.
IMS
DBRC is used if the IMSCTRL macro statement specifies DBRC=YES or DBRC=FORCE. Otherwise, DBRC is not used.
Y
DBRC is used.
N
DBRC is not used, unless the IMSCTRL macro specifies DBRC=FORCE.

The DBRC parameter is used when the ACBs are managed by your installation (ACBMGMT=ACBLIB) and the database being accessed is not a HALDB or a HALDB partitioned secondary index.

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

If you do not want the user to override the value you specify for this parameter, set UDBRC=N.

Notes:
  • When the database being accessed is a HALDB, DBRC is used unless the database is the IMS catalog and the REGCATLG parameter is set to N.
  • When the database being accessed is a HALDB partitioned secondary index, DBRC is used unless the database is the IMS catalog's secondary index and the REGCATLG parameter is set to N.
  • When IMS management of ACBs is enabled (ACBMGMT=CATALOG) DBRC is used unless the REGCATLG parameter is set to N.
