DFSMStvs supports the data set forward recovery option introduced into VSAM cluster definitions by VSAM RLS. DFSMStvs logs the redo records to system logger log streams. These log streams are shared across all DFSMStvs instances and CICS® systems. This provides sysplex-wide, merged log streams, which you can use as input to CICS VSAM Recovery (CICSVR) or other forward recovery products. To enable these products to process DFSMStvs forward recovery log records with minimal changes, the log records were designed to be as similar to those written by CICS as possible.

CICSVR version 2 release 3 or higher is needed.
