APAR status

  • Closed as program error.

Error description

  • In some situations an MQ appliance operating in an HA group
    could report an incorrect status when there are failures on both
    nodes. In this case, the "status <qmgr>" command may report "HA
    Status: Normal", when the status is in fact "HA Status: Resource

Problem summary

  • ****************************************************************
    Those using MQ Appliance configured with the High Availability
    (HA) features.
    Platforms affected:
    The fix for APAR 'IT29783: Querying queue manager status may
    cause performance overheads on MQ appliance' introduced a
    possible problem in HA operation where an incorrect status could
    be reported if there are failures on both nodes.
    This issue was seen when the first appliance encountered a
    low-severity failure, which would normally be handled internally
    and not reported to the user, before the second appliance
    encountered a severe failure, which should change the reported
    status. A logic error meant that the low-severity failure
    suppressed reporting of subsequent failures.

Problem conclusion

  • The code has been modified to correctly report the status when
    there are failures on both MQ appliance nodes.
    The fix is targeted for delivery in the following PTFs:
    Version    Maintenance Level
    v9.2 LTS
    v9.x CD    9.2.1
    The latest available maintenance can be obtained from
    'WebSphere MQ Recommended Fixes'
    If the maintenance level is not yet available information on
    its planned availability can be found in 'WebSphere MQ
    Planned Maintenance Release Dates'
