Defining the OTMA XCF member name

XCF requires an XCF member name for each member of an XCF group.

You can specify an XCF member name for OTMA by using the OTMANM parameter. If you do not specify the OTMANM parameter, OTMA uses the APPLID of the IMS system as the OTMA XCF member name.

The OTMANM parameter is not used in Extended Recovery Facility (XRF) installations. Instead, IMS uses a USERVAR name as the XCFmember name. The USERVAR name is specified in either the IMS control region JCL, the DFSPBxxx PROCLIB member, or the DFSHSBxx PROCLIB member.

Recommendation: Do not change the group name or the IMS member name during an IMS emergency or normal restart.
