PM80201: AB04E RC00D93011 DSNRGLM1.DSNRUC01 +08DE ON COMMIT IN SQLPL PROC

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• On a COMMIT within a DB2 native SQLPL procedure, the following
  abend may occur:
     ABEND04E RC00D93011 at DSNRGLM1 . DSNRUC01 +08DE
  
  Additional search keywords: SQLNATIVESQLPL SQLPROCEDURE
                              SQLCOMMIT
  

Local fix

• If possible, remove the COMMIT from within the SQLPL procedure
  and, instead, issue the COMMIT in the caller 'after'
  the procedure completes.

  ****************************************************************
  1a. When a migrated native SQL procedure calls itself or
  another stored procedure defined with COMMIT ON RETURN YES
  attribute, DB2 does not perform the COMMIT upon returning from
  the nested procedure.
  .
  1b. When an RRSAF application calls a native SQL procedure
  (eg SP1), which then calls a migrated native SQL procedure
  with COMMIT ON RETURN YES (eg SP2), the error can occur after
  SP2 has completed the COMMIT ON RETURN. This is due to
  the interest in the RRS UR not being deleted causing the
  reported SQLCODE -615 problem with the subsequent DROP because
  the following caller's COMMIT does not eallocate the stored
  procedure package.
  .
  2. When the COMMIT has been issued inside a native SQL
  procedure, the module which issued the COMMIT had not checked
  the return code and thus did not issue the subsequent ROLLBACK.
  The reported problem occurs because the missing implicit
  ROLLBACK causes Phase 1 COMMIT to fail due to a connection
  failure.
  

Problem conclusion

• 1a. DB2 code has been modified to perform COMMIT ON RETURN for
  the called procedure when returning back to the calling
  Native SQL PL procedure.
  .
  1b. DB2 code has been modified to delete the interest on the
  RRS UR during the COMMIT ON RETURN.
  .
  2. DB2 code has been modified to check the COMMIT's return code
  and issue the appropriate implicit ROLLBACK upon failure.
