If you want to turn off CICS® VR automatic deregistration for log streams, backups, or change accumulation data sets, perform the following steps:
Specify blanks in all input fields in the deregistration secondary windows, then press Enter.
Specifying a value of zero for the retention period fields does not turn off CICS VR automatic deregistration. A retention period value of zero indicates that CICS VR immediately deregisters, and optionally deletes, all information related to the retention period setting during the next execution of CICS VR automatic deregistration.on.
