Error description

  • Abend AEIU / ILLOGIC errors occur after upgrade to CICS TS 4.2.
    The ILLOGIC error is being returned on a DELETE request that is
    made through the path. CICS trace shows that the request is
    getting an exclusive control conflict ( 080514 ). CICS retries
    the ERASE request but the task again receives the 080514
    response and the task is put in an FCXCPROT suspend. CICS then
    retries the ERASE request against the base but after the request
    returns from VSAM, CICS returns an ILLOGIC error (RESP=21
    RESP2=110) to the application.

    ****************************************************************
    A delete of a record from a path is issued. The erase call to
    VSAM returns 080514, indicating an exclusive control conflict
    and the fact that the upgrade set may be inconsistent. CICS
    needs to reissue the erase but against the base file. Routine
    RETRY_DELETE_USING_BASE_KEY is called, but this saves and
    restores the existing vswarpl around the call to erase the base
    file's record. When it then tests vswartnc to see if the erase
    has worked, it still contains 08 from the original exclusive
    control conflict. This results in the error path being taken and
    illogic being returned to the application.

Problem conclusion

  • DFHFCVS has been altered to test the result of the erase call
    against the base file when deciding whether the retried delete
    has worked or not.
