Error description

  • As documented by APAR PK28707, TWS z/OS can handle up to
    one minute in time discrepancy for JMRENTRY if the NJE node
    is different between the A2 and A3J tracking records.
    However, if the NJE node is the same, any difference in
    value between the JMRENTRY of the A2 record and the JMRENTRY
    of the A3J record will cause a CCUN error.
    There is no known reason for the JMRENTRY value to ever be
    changed once the job starts execution; however to make it
    easier to determine that a CCUN error has been caused by
    a JMRENTRY discrepancy, a new message will be added which
    will be issued to the controller EQQMLOG.  If this message
    is seen, the appropriate action will be to set the
    indicated operation to complete status (by a manual change).
    Note the JMR (Job Management Record) values JMREDATE and
    JMRENTRY are stored by TWSz as EXRRDATE and EXRRTIME.
    Field EXRJSRDR is comprised of the EXRRDATE and EXRRTIME
    values.
    The JMREDATE/JMRENTRY values are not expected to change during
    job execution, so TWSz does not recognize the events as
    referring to the same job if they report different times.
    Since the A3J record is not processed, the A3P record will be
    SUSPENDED, causing CCUN status when the A5 record is received:
    EQQE036I JOB jjjjjjjj(JOBnnnnn) ENDED IN ERROR CCUN. PRTY=p,
    EQQE036I APPL = aaaaaaaaaaaaaaaa, WORK STATION = wwww,
    IA=yymmddhhmm
    Circumstances other than a JMRENTRY difference can cause a
    CCUN error, so the new message will clarify this.

Problem conclusion

Temporary fix

Comments

  • if an unexpected JMR time change (not caused by a route)
    occurred that affect job events  and the discrepancy is <= 1
    minute, a new message (EQQE206W) will be issued to describe
    the operation, the discrepancy measured in hundredths
    of a second and the event reporting the discrepancy.
