PM26949: ABEND0C4 RC10 AT DSNX9MON OFFSET 0A9C DUE TO ERROR LE NOT INITIALIZED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DYGT,ABND=0C4-00000010,U=SYSOPR  ,M=C8
  ,C=101.ASMC-DSNVEUS3,M=DSNVEUS3,LOC=DSNXGRDS.DSNX9MON+0A9C
  This issue is fix in APAR PM21317 for R910.
  ABEND0C4 in DSNX9MON+0A9C may occur due to buffer not allocated
  during dsnxinit when ceepipi load fails
  

Local fix

• A circumvention to avoid this abend is to set the LEMAX
  zparm value to a value higher than ZERO.  Setting LEMAX
  to zero disables LE environment usage by DB2, and has a
  consequence of disabling certain built-in functions that
  DB2 provides, like UPPER , LOWER , COS , etc.  The reason
  for this abend was that LEMAX was zero.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DB2 9 and DB2 10 for z/OS users with     *
  *                 zparm LEMAX = 0.                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: ABEND0C4-38 in DSNSVSFB or ABEND0C4-10  *
  *                      in DSNX9MON may occur when the DB2      *
  *                      subsystem is being stopped and zparm    *
  *                      LEMAX is 0.                             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The abend occurs during stop DB2 if zparm LEMAX has been set to
  zero. DB2 does not initialize LE and set up its buffers if
  LEMAX is zero. During stop DB2, the cleanup of LE abends because
  it has not been set up.
  
  With the fix provided in this APAR, the skipped initialization
  is tolerated during DB2 stop.
  
  Changing LEMAX to some non-zero value will also work around the
  abend.
  

Problem conclusion

• Code was changed to tolerate the case when LEMAX is 0 during DB2
  stop.
