Error description

  • The dump shows the progression of the 0C2/AKEA which occured in
    module DFHDTPC which leads to the AKEA reported in DFHDTRR and
    finally the DFHFC0001 AKEA at offset X'03E2' in module DFHFCDTS.
    .
    The trace where taskA and taskB initially issued a READ for
    fileA  on L8 tcbs. TaskA issue a close for the file on
    after moving to the QR tcb. When Task B attempts to complete
    the READ of the file after changing to the QR TCB the DFHFC0001
    occurs in DFHFCDTS. The FCTDTTKN field for fileA is zeroes.

    * PROBLEM DESCRIPTION: CICS application encounters an AFCZ     *
    *                      abend on reading a remote UMDT.         *

    * RECOMMENDATION:                                              *
    ****************************************************************
    Two CICS transactions attempt to read a UMDT (User Maintained
    Data Table) simultaneously. Both test whether or not the file
    is open in module DFHFCFR and find that it is open.
                                                                   .
    At this point the tasks each try to switch to the QR TCB
    (if they are not there already).
    Both will then invoke DFHFCDTS to do the read, but before
    this occurs, the remote file is closed on the FOR.
    The first task sees that the file has been closed, and
    issues a local close via DFHFCFS. The read request is then
    shipped and a NOT_OPEN response is returned.
                                                                   .
    When the second transaction gets the QR TCB, it abends AFCZ
    in DFHFCDTS as the table has been closed and the token CICS
    holds for this table is no longer valid. A system dump is taken
    and the joblog shows:
                                                                   .
    An abend (code ---/AKEA) has occurred in module DFHFCDTS.
                                                                   .

Problem conclusion

  • DFHFCFR has been amended so that it tests whether or not the
    file is open after the switch to the QR TCB takes place.
    DFHFCDTS will no longer be called with a bad token, instead the
    request will be immediately function shipped to the FOR.
