Error description

  • You are getting DFHLG0514 JOBA Log stream xxxx.xxxxxx.xxxxxxx is
    in use by another CICS system.
    This is followed by:
       DFHFC0523 JOBA RLS OPEN of file 'filename' failed.  The
    LOGSTREAMID for forward recovery is the same as the system log.
    Module DFHFCRO.
    .
      When in fact it is this system which owns it.
    .
    **  GRSTRACE shows :
    MAJOR NAME: DFHSTRM
    .
    MINOR NAME: xxxx.xxxxxx.xxxxxxxx
      SCOPE: SYSTEMS   SYSNAME: ABC       STATUS: *SHARED*    /OWN
        ASID: 000000nn   TCB: nnnnnnnn    JOBNAME: JOBA
        Critical ENQ Time(s):
          Request: MM/DD/YYYY HH:MM:SS.mmmm
          Grant:   MM/DD/YYYY HH:MM:SS.mmmm
    .
     The status on the GRSTRACE is shared, not exclusive, so you
    would not expect the DFHLG0514. Also ENQ'ing occurs on first
    connect.

    ****************************************************************
    When a file in CICS is using a forward recovery log, message
    DFHLG0772 may occur due to IXGCONN connect failure on RO TCB.
    After the IXGCONN failure, CICS switches to the QR TCB as CFDT
    region status server work must be done under the QR TCB. The DEQ
    against the logstream failed with message DFHLG0002 error code
    x'0532' which indicates MVS_STREAM_DEQ_FAIL. The DEQ failure is
    because MVS ENQ/DEQ must be done in the same MVS TCB. DFHLG0514
    & DFHFC0523 may be reported later if another FILE API is issued
    to that file, which says the logstream is in use by another CICS
    system.

Problem conclusion

  • CICS module DFHLGST has been changed so that the MVS DEQ will be
    issued on the RO TCB.
