Error description

  • Program DFHEPC is suffering from an ABEND0C4/AKEA
    at offset x'E62'. The failing instruction is:
    .
    000E68 D210 7CB8 2000 00CB8 00000 30957
    MVC   UEX_SAVE_ARG0,0(RARG0) make copies of Arg0...
    .
    DFHEPC is trying to access Arg0 at the end of the
    program but the program is at the end of an extent
    and cannot read the next extent which is isolated due to
    transaction isolation being active.

    * RECOMMENDATION:                                              *
    ****************************************************************
    A customer's program contains the program's EXEC interface
    stub at the beginning of the program and an EXEC CICS LINK
    command at the end of the program. The program is loaded at
    the very end of an extent. When the LINK is processed, with
    CICS transaction isolation active, DFHEPC attempts to move
    arg0 into UEX_SAVE_ARG0 and abends because it tries to move
    17 bytes instead of 9, thus touching storage not owned by
    this task.

Problem conclusion

  • DFHEPC has been changed so that when an attempt is made to move
    arg0 into UEX_SAVE_ARG0, 9 bytes will be moved instead of 17.
