Definition

• NO specifies that DB2 backward log processing should process all inflight and inabort units of recovery (URs).
• YES postpones backout processing for some units of work until you issue the command RECOVER POSTPONED.
• AUTO postpones some backout processing but automatically starts the backout processing when DB2 restarts and begins accepting new work.

With YES or AUTO, backout processing runs concurrently with new work. Page sets or partitions with backout work pending are unavailable until their backout work is complete.

In R/3 environments recommended value for this parameter is 'No'.
