The Recovery Manager functions and utilities use the Cross-System Coupling Facility (XCF) feature of the operating system.

If the Recovery Manager functions and utilities are active in the operating system, all Backup and Recovery utilities for IMS will attempt to join an XCF group that is established at startup of the Recovery Manager functions and utilities.

To ensure that the XCFMEMBER limit will not be exceeded when multiple utility jobs are initializing simultaneously, review and adjust (if necessary) the operating system definitions for XCF. You can enter the following command from the system console:

/D XCF,COUPLE

The command response indicates the maximum number of members that are defined and the maximum number of members that have been used, as shown in the following example:
