This looks to be
introduced by APAR PH21519 PTF UI69949. The target of the
executed MVC in DFHXCPRH has been built incorrectly leading to
the 0C4.

  • NA

Problem summary

  • ****************************************************************
* USERS AFFECTED: All CICS users with UI69949 applied.         *
****************************************************************
* PROBLEM DESCRIPTION: ABEND0C4 in module DFHXCPRX with PTF    *
*                      UI69949.                                *
****************************************************************
With PTF UI69949 applied an EXCI DPL call can result in an 0C4
when moving a UOWID as part of a call to DPL into CICS.
The abend occurs in module DFHXCPRX, CSECT DFHXCPRH, on an
EXECUTE instruction because of an invalid base address being
used for the EXECUTE instruction.

Problem conclusion

  • UI69949
DFHXCPRH is changed to correct the failing MVC instruction by
providing the correct base address for the EXECUTE.

Temporary fix
