If an application program abends and Batch Backout needs to be invoked by Mainframe Program Restart Manager for IMS for z/OS (PRM) to remove updates which
occurred after the last checkpoint, DUAL LOGGING will be done by default for the log records written by Batch Backout. This is even true when the application program execution
itself is only using SINGLE LOGGING.
To avoid DUAL LOGGING being used with Batch Backout invoked by PRM, add the PRM run option "IEFRDER2=DUMMY" to the application program execution.
This forces SINGLE LOGGING being used with Batch Backout (instead of using DUAL LOGGING by default).
