AMQ5008S: An essential IBM MQ process 521573 (amqzfuma) cannot be found and is
assumed to be terminated.
EXPLANATION:
1) A user has inadvertently terminated the process. 2) The system is low on
resources. Some operating systems terminate processes to free resources. If
your system is low on resources, it is possible it has terminated the process
so that a new process can be created.
ACTION:
IBM MQ will stop all MQ processes. Inform your systems administrator. When
the problem is rectified IBM MQ can be restarted. |

So what changed, who changed it, and why did they change it?

Are you saying that changing RWX permission bits resolved the issue? Precisely what was changed?

To avoid confusion, and provide a timeline:
1. The permissions were correct prior to a reboot of the standby server, or dismount/remount of the file system, i.e. strmqm -x was successful on the standby server?
2. The standby server was rebooted, or the file system was dismounted/remounted, after which the file system permissions were incorrect and strmqm -x was unsuccessful on the standby server?
Whether the file systems auto-mount, or manually remounted, part of the procedure should be to re-establish the correct ownership and permissions.

Hi Exerk
We faced this problem on DR servrs.when i try to bring the qmgr up using strmqm -x on the first server then i faced this problem.File system is manually remounted ,I think at that time permissions are changed.After network admin modified the correct permissions then issue got resolved. |

Please be more precise. Which file system(s)? Which permission(s)?
For example, did you/they grant x (execute) to IBM MQ internal programs to non-mqm - user/group/other?

Hi Bruce,
Sorry i dont have exact details.Now i don't have access to servers also. i worked with them to setup multi instance few months back.Now they want to move to DR and they contacted me when they faced this issue.Intially i thought issue is with MQ .i am able to create new dummy qmgr on the DR server but when we try to create new dummy multi instance qmgr using this shared path then not able to create. So I told them issue is with shared file system.They checked with network admin. |

And the issue should have been identified and corrected then, when you should have carried out an uncontrolled failover, i.e., a power-interrupt of the Primary server.

This illustrates a lack of due diligence and a test plan - takeover/failover should have been tested after creation of the queue manager, independent of the applications, and then with the applications connected to test their reconnection capability.
