We are changing the MQ Queue manager operating system from Sun Solaris to redhat linux. we have all Queues channels etc defined on Solaris. Can we copy all the current MQ settings to one file and then run that file in the new redhat linux server. Is there any way to do this?. Please let me know if there is any procedure to do this.

Look up saveqmgr on the forum or the IBM site.

You will need to do a fresh install of the MQ product using the linux distribution files. If you have any custom attributes in the qm.ini file, they will need to be set in the new server. (I don't know if you could just copy that file. I wouldn't, myself, but others may overrule me.)

If you are using any exits, they will of course need to be recompiled.

As far as the MQ objects themselves (queues, channels, listeners, processes, etc), my worthy associate has already pointed you to the correct utility.

You may also have to make adjustments to the kernel, as you did with Solaris.

And set up your users and groups and OAM security profiles.

Review your channel names as there may be references to the old qmgr or host name.

using the command
Code:

  runmqsc MYQMGR < saved_definitions.mqsc


Is the best way of using the output from saveqmgr.

Many sites save this file (or others that perform the same function) in sourcecode management systems such as CVS, Subversion etc. You do use one don't you?

It is a very fast operation to rebuild a qmgr this way and will often be far less a problem than restoring it from a backup.

I have scripts that create the QM, Create the Queues and even load my 'setmqaut' settings. The different versions run on Windows, Unix & Linux but all use the same input files that hold the definitions. This is the sort of toolkit than any self respecting MQ 'guru' has in their toolbox. Why re-invent the wheel every time?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

and dont forget to start the listener manually when you rebuild the qmgr with the saveqmgr.
