Batch backout
Prior to executing an emergency restart with the COLDSYS parameter (/ERESTART COLDSYS), run the Batch Backout utility with either the COLDSTART or ACTIVE parameter.
Provide DBRC with the names of the logs to protect registered databases (that need to be backed-out) from being accessed until their backouts are complete.
For DB level control, if you choose not to back out an unresolved in-doubt UOR, use the DELETE.BKOUT command to remove it from the BACKOUT record.
Attention: Use the DELETE.BKOUT command
with extreme caution. It deletes all backout information for a subsystem
from the RECON data set.
