Dear All,
 I am new to MQ.
My manager asked me to take (QMGR) backup of /var/mqm.
what does that mean exactly?
Should I copy entire folder(/var/mqm) and move it to another share drive?
or
Shall I create a tar file and then move ?
or
Shall I use any third party tool.
Regards
Anil |

I will just say what's done in a queue manager backup
Back up definitions. Use saveqmr (ms03) support pac for that. Google it!
I never do the step below during a backup only process:
Back up directories: errors, log, Qmgrs, exits and the journal file in the /var/mqm directory.
I hope you did not wait for this answer! |

And on later versions of MQ there is the
dmpmqcfg
command which does very much the same job as saveqmgr
BUT, BUT, BUT
There are some known problems with it missing some authourity definitions so follow it up with something like the following
| Code: |
amqoamd -m QMGR -t qmgr -s > QMGR_oadefs.bat
amqoamd -m QMGR -t chl -s >> QMGR_oadefs.bat
amqoamd -m QMGR -t q -s >> QMGR_oadefs.bat

Which also has some known problems...

Dear all thank you very much. 
I forget to mention. I have already taken backu of Queue manager objects and authorizations using MS03 package. That has been successfully completed.
but he is asking to take backup of /var/mqm directory.
I am bit of confused now.
regards
Anil |

He is probably assuming the queue manager data/log files are under that directory. This is not necessarily the case.
But if you must save it - use tar to do it. Then you can zip the tar file.

A successful backup plan implies that you have a restore plan, and that you have successfully tested the restore.

And that the business unit allows for that test...

Only one person knows exactly what that means, your manager.
You will need to stop the queue manager if you want to take backups of its files using a typical file backup solution (i.e. tar up the dir and store a copy elsewhere)
If the servers are virtual, backups can occur below the hypervisor level while the server and MQ continues to run and the backups will be viable.
As others have stated, backups are really nothing more than untested restores. Maybe ask your manager how he sees a backup of /var/mqm being used. It will help determine what exactly you need to do.

That mess was fixed in FixPack 7.5.0.4.

And of course that back up is valid for only that moment in time when it was taken - subsequent message traffic, even if it's only one message, immediately invalidates the back up.
EDIT: On the assumption that application queues are not empty

Sorry to hijack the original question, and I can do a quick search when Im home on this. What was the issue with the earlier versions in 7.5? Thanks
And now back to the original issue for poster.. |
