The IBM® default values for the log stream blocks and log stream copies retention periods are blanks. Therefore, automatic log stream deregistration is initially turned off. While the automatic log stream deregistration setting remains OFF, no information relating to log streams or log stream copies is deregistered periodically by CICS VR.
The Automatic individual deregister field shows whether an individual retention period is specified for any log stream. If set to ON, a log stream does have an individual retention period specified. If set to OFF, no log streams registered to CICS VR have individual deregistration criteria specified.
You can change the automatic log stream deregistration setting to ON by specifying a value between 0 and 999 for one or both of the retention period settings and pressing enter. Once the automatic log stream deregistration setting is changed to ON, CICS VR periodically deregisters, and optionally uncatalogs and deletes, information that is older than the specified retention period value(s).
