CICS VR XCF group considerations

All systems in a sysplex that run a CICS® VR instance that belongs to the same CICS VR XCF group must have the same value specified for the CICSVR_RCDS_PREFIX parameter. CICS VR contains logic to ensure all CICS VR instances in the same CICS VR XCF group use common RCDSs.

The RCDS prefix defined for the first system that activates the CICS VR server address space in a CICS VR XCF group is used for all instances in the same CICS VR XCF group. Therefore, if you need to change the value of the CICSVR_RCDS_PREFIX parameter for a CICS VR XCF group, you must:
  • Terminate all CICS VR instances that belong to the same CICS VR XCF group.
  • Change the CICSVR_RCDS_PREFIX value on all systems.
  • Restart all CICS VR instances that belong to the same CICS VR XCF group.
