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.
