Forward recovery

CICS® VR uses the after-images on the logs to forward recover your VSAM spheres; it cannot forward recover a VSAM sphere that does not have an associated log containing after-images.

CICS VR accepts logs on disk, tape, or cartridge; the CICS VR archive utility and the ISPF dialog interface cannot process uncataloged logs on tape or cartridge. If you run CICS VR manually, without using the ISPF dialog interface, forward recovery and backout can process uncataloged logs.

CICS VR can recover base clusters with path updates; it cannot recover a base cluster with path updates if the base and path updates are recorded on separate logs. Record base and path updates on the same log.
