Activating CICS VR batch logging overview

The steps required to activate three types of batch logging for VSAM data sets, forward recovery logging, undo logging, and forward recovery and undo logging.

The steps assume that you are enabling the associated types of batch logging for the first time on the system. Therefore, some steps, such as specifying parameters in the active IGDSMSxx parmlib member, do not have to be repeated when enabling similar logging for other VSAM data sets on the same system. Refer to the remainder of this section for details of the listed steps:
Enabling forward recovery logging for a VSAM data set
  • Specify FRLOG(REDO).
  • Enter the name of the forward recovery log stream in the LOGSTREAMID (name of log stream) parameter.
  • Create the specified forward recovery log stream, if it doesn't already exist.
  • Authorize CICS® VR access to the specified forward recovery log stream.
Enabling undo logging for a VSAM data set
  • Specify FRLOG(UNDO).
  • Specify the CICSVR_UNDOLOG_PREFIX(prefix) parameter in the active IGDSMSxx member.
  • Create the undo log stream, using the specified CICS VR undo log prefix (if it doesn't already exist).
  • Authorize CICS VR access to the specified undo log stream.
  • Specify the CICSVR_UNDOLOG_CONTROL(string) parameter in the active IGDSMSxx member.
  • Specify the CICSVR_BACKOUT_CONTROL(string) parameter in the active IGDSMSxx member.
Enabling forward recovery logging and undo logging for a VSAM data set
  • Specify FRLOG(ALL).
  • Enter the name of the forward recovery log stream in the LOGSTREAMID(name of log stream) parameter.
  • Create the specified forward recovery log stream (if it doesn't already exist).
  • Specify the CICSVR_UNDOLOG_PREFIX(prefix) parameter in the active IGDSMSxx member.
  • Create the undo log stream, using the specified CICS VR undo log prefix (if it doesn't already exist).
  • Authorize CICS VR access to the specified forward recovery log stream and undo log stream.
  • Specify the CICSVR_UNDOLOG_CONTROL(string) parameter in the active IGDSMSxx member.
  • Specify the CICSVR_BACKOUT_CONTROL(string) parameter in the active IGDSMSxx member.
