MVS log stream retention period

If you want CICS® VR periodically to deregister and delete information related to forward recovery and log of logs log steams, specify a number between 0 and 999 in the Retention period for blocks field and press enter.

Once a retention period for blocks has been specified, CICS VR periodically deletes information from the RCDS that relates to information on MVS™ log stream blocks that are older than the specified retention period. In addition, CICS VR deletes any MVS blocks on all registered log streams; forward recovery and log of logs log streams, that are older than the specified retention period.

The retention period for blocks value applies to all registered forward recovery and log of logs log streams that are registered to CICS VR. You can specify a separate retention period for individual forward recovery or log of logs log streams using the CICS VR individual log stream deregister secondary window. See Understanding what is deregistered and deleted by CICS VR automatic deregistration for more information about what CICS VR deregisters and delete when automatic deregistration is turned on.
