Set up scan as a batch job that can be run at regularly scheduled times as shown in the sample.
Run scan several times a day, for example; every four hours, on all the necessary systems to keep the RCDS current. If you have multiple log streams, for example; more than one system using DASD-only logging, or if you use both coupling facility logging and DASD-only logging, consider scheduling your batch scan jobs so that they run at different times to avoid contention, that is, system level enqueues.

LOGOFLOGS SCAN
The LOGOFLOGS command in the sample above tells CICS® VR to scan all the log of logs that are registered in the RCDS. All the information needed for recovery is stored in the RCDS. In addition, CICS VR automatic deregistration is performed if it has been turned on through the CICS VR panel interface. Use the CICS VR panel interface to set or change the CICS VR automatic deregistration settings.
Each time that scan is run, CICS VR begins at the point in which the last scan ended. For more information on scan see the LOGOFLOGS command in LOGOFLOGS: Process a log of logs.
