Activating the CICS® VR server address space

The CICS® VR server address space provides a communication vehicle for CICS® VR and other applications. It must be active if you want to use any of these CICS® VR functions.

  • CICS® VR VSAM batch logging.
  • Notification and registration of DFSMSdss and other logical backups in the CICS® VR RCDS.
  • Automated change accumulation processing with DFSMSdss logical dumps and logical copies.
  • Notification of CICS® TS backout failures.
Note:
The CICS® VR server address space is not required to use DFSMShsm; however, if the CICS® VR server address space is enabled, all user IDS running CICS® VR must be authorized to issue DFSMShsm-authorized commands. See Authorizing user IDS to issue DFSMShsm commands.
