PM28704: EXCESSIVE DSNB357I MESSAGES WERE FLOODING THE CONSOLE DB2STGLK/J

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MSGDSNB357I is displayed in a tight loop during a DB2
  restart following a temporary loss of a Coupling Facility.
  LPL recovery and DB2 restart are very slow.
  An inconsistency in DB2 code has been found that may lead to the
  excessive DSNB357I messages
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: DB2 users.                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: Excessive DSNB357I messages, indicating *
  *                      automatic LPL recovery suppressed.      *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The DSNB357I messages (automatic LPL recovery suppressed) are
  supposed to be limited in the same way that the DSNB250E
  messages (page range added to LPL) are.  However, the limiting
  of the messages may not be effective for multi-piece non-
  partitioned pagesets, for two reasons:
    - An inconsistency in which PB0 control block is checked for
      the DSNB250E message count.
    - For the case of an open failure, a PB0 may not exist for the
      dataset associated with the page being added to LPL.
  

Problem conclusion

• The LPL logic has been modified to maintain only one DSNB250E
  message counter for non-partitioned objects - in the first PB0.
