DFS982I I/O ERROR READING BACKOUT QUEUE, BSN=bbbbbbbb RC=rr


or

I/O ERROR READING BACKOUT QUEUE COVERING SYSTEM CHKPT=yyddd/hhmmss BSN=bbbbbbbb RC=rr

Explanation

The first message is issued only in batch. The second message is the online (TM and DBCTL) form of the message, where yyddd/hhmmss is the last system checkpoint ID that occurred before the start of the unit-of-recovery being backed out. An error occurred while reading the log. If an I/O error occurred, message DFS0414I should be issued.

If DBRC is active, it must be notified when the database is recovered. If DBRC is inactive, this message might be issued again, even though recovery is no longer required. DBRC is notified automatically when Batch Backout is run.

This message can also be issued when a problem occurs and there is an excessive number of records to back out and some records needed for backout had already been archived.

In the message text:
bbbbbbbb
Indicates the log block sequence number.
rr
Indicates the log return code.

System action

IMS processing continues, but the backout fails.

For the first form of this message, take the X'67FF' log records to the IMS log.

For the second form of this message, take the supervisor call (SVC) dump.
