What is CICS VR forward recovery for CICS TS?

CICS® VR forward recovery helps you to recreate a VSAM sphere from a backup copy of the sphere.

Use the panel interface to build and submit a recovery job that restores the VSAM sphere from a selected backup, then reapplies all changes made to the VSAM sphere since the selected backup was taken. This returns your sphere back to the exact state before it became corrupted. The sphere can be an entry-sequenced data set (ESDS), a key-sequenced data set (KSDS), a fixed-length relative record data set (RRDS), or a variable RRDS (VRRDS). CICS VR obtains the information that it needs to construct the recovery job from the CICS VR RCDS.

The CICS VR selective forward recovery function provides a way for you to remove unwanted changes to VSAM spheres. By specifying certain log records to be excluded when CICS VR is performing a forward recovery on a backup, unwanted updates can be removed from the data set.
