  • 1.  MQ's status is Running elsewhere

    Posted Tue January 30, 2024 07:07 AM

    Hi All,

    The scenario: after AWS Instance freeze, the server was restart it. The problem is that MQ can't start since the status as running elsewhere.

    "The QM is associated with installation 'Installation1'. IBM MQ Queue Manager is already running elsewhere. It doesn't permit standby instances."

    How can I fix this?

    Thank you.

    Hi, It seems like you have a multi instance setup.

    Please have a look at:

    Hi Goel,

    No, we don't want multi instance setup. But, the MQ's configuration is place on AWS EFS shared disk. So, maybe that's why if suddenly terminate and create a new instance the problem happens. 

    Thank you

    Then probably the EFS was not released by the server completely and thus a new queue manager has been created on another server. Is your server part of an auto scaling group, because that may explain why this has happened.

    If the qmgr is multi-instance and on one server it was started as a single-instance then when you try to start it on the standy server it will give an error.  so the fix is:  stop the qmgr (endmqm <qmgrname> and start it as a multi-instance (strmqm -x gmqrname).  Then go to the server where it is in Running elsewhere" status and do strmqm -x qmgrname.  This should fix it back as a full-fledged multi-instance qmgr with a standy instance ready to take over if needbe.
