Hi,
I am running MQ 5.3 on win2k and planning a backup strategy. Can I please have a feedback on the best way to backup MQ? My plan is the following:
1. Stop all channels
2. Perform rcdmqimg
3. shutdown queue manager
4. End listener
5. backup MQM folder on tape
6. Restart queue manager
7. Restart listeners
8. Restart the channels
To me it looks like a pain if I try to automate this since there are timing issues. Any suggestions?
Thanks,
Sas |

Sassaidi,
We do exactly this.
But we do it all from a script. However our base is UNIX.
You may have to use amqdain if you are running on a M$ base.
Enjoy  |

Didnt want to start a new topic so just adding here,
Trying to think how a shell script can be used to stop all channels of a queue manager.
These are the options to stop a channel
| Code: |
STOP CHANNEL(channel_name) [ MODE( QUIESCE | FORCE | TERMINATE ) ]
[ STATUS( STOPPED | INACTIVE) ]
[ QMNAME(qmname) ]
[ CONNAME(connection_name) ]
|
Anyone have any ideas.
How do you guys do it because the backup manual suggests to stop the channels of the QMs first and then run the rcdmqimg command and then proceed to shutdown of the QMs.
is it absoultely critical to stop the channels for backup?
i just need help with the stop channels part.
thanks. |

There should not be any need to stop the channels before stopping the QM. They will be stopped as part of that process.
And if you use the -w option on endmqm, your script will wait for the QM to end before continuing.
Cheers,

You may not want to specify status(INACTIVE) if the channel is Triggered. If an application puts a message for remote delivery the channel will start again.

We use a script
script file contains:
| Code: |
STOP CHL(CHL1)
STOP CHL(CHL2)
STOP CHL(...CHLn)
|
and we run it
| Code: |
| runmqsc QMGR < script > stoplog |
Then we run the imaging (rcdmqimg)
Then we stop the qmgr
do the backup
start qmgr
run script starting the channels.
You DO want to stop all the channels and shutdown all applications using the qmgr in bindings mode to have a clean offline backup image that matches the one taken by rcdmqimg.
Enjoy  |

| Stating the obvious perhaps, but on windows (the original raiser!) backup the registry MQSeries tree (under HKLM\Software\IBM) as well... |

this solution will just work fine for me.
will try to add the status part in the script itself.
| Code: |
STOP CHANNEL(chlname) status(STOPPED)
|
i have found that to be more reliable and of course i will have to worry only about application queues.
Good point JasonE about the windows part.
thanks again to all who replied. |

You shouldn't have to specify (STOPPED). It is the default when you run "stop chl".
