Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of Native SQL procedures bound in  *
  *                 DB2 9 and executed in DB2 10.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: Overlay may occur if allocated storage  *
  *                      is exceeded when converting SQL         *
  *                      statement to be prepared to UTF-8.      *
  *                      The following abend may occur:          *

  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  During a PREPARE within a native SQL procedure, the SQL text
  was converted to UTF-8 from its original EBCDIC format. The
  expansion of characters, due to an in-place conversion,
  exceeded the storage allocated. This can introduce a storage
  overlay if the allocated storage is exceeded.
  Performing an ALTER REGENERATE of the DB2 9 native SQL
  procedure on the DB2 10 system can mitigate this problem.
  

Problem conclusion

• DB2 was changed to allocate three times the usual storage
  amount to accomodate the possible expansion of SQL text
  characters from in-place EBCDIC conversion to UTF-8.

  *********
  APARFIX AM71949 HAS BEEN PROVIDED TO FIX THE ISSUE. IN
  ADDITION, WITHOUT THE APARFIX, PERFORMING ALTER REGENERATE
  OF THE DB2 9 NATIVE SQL PROCEDURE ON THE DB2 10 SYSTEM CAN
  MITIGATE THE PROBLEM.
