CICS VR capabilities and limitations

Descriptions of the capabilities and limitations of CICS® VR.

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.
Alternate indexes
CICS VR batch backout
CICS VR uses the before-image log records to back out updates that are made by a batch job. CICS VR undo logging can produce before-image log records for updates that are made to VSAM spheres by batch jobs.
VSAM data set attributes
CICS VR can detect whether the VSAM attributes of the target VSAM sphere in a recovery run differ from the attributes of the sphere as recorded on the log.
Extended Addressability mode support
CICS VR supports the Extended Addressability mode for ESDS, KSDS, RRDS and VRRDS VSAM spheres.
DFSMShsm
CICS VR can restore VSAM spheres from DFSMShsm logical backups and logical dumps.
DFSMSdss
CICS VR can keep an inventory of and restore DFSMSdss logical copies and dumps created for VSAM base clusters.
ABARS
CICS VR can keep an inventory of and restore backups created by ABARS.
Other logical backups
By using the CICS VR file copy notification service, CICS VR can maintain an inventory of, and list through the panel interface, logical backups made using other backup products (IBM® or non-IBM).
