Best practices for a MQ network, consisting of distributed, z/OS and iSeries platform - please share if you can, thanks!

Somewhat of an open ended question I suspect. You have a mixture of everything there, a good old heterogeneous mixture of platforms which is EXACTLY what MQ is good at.

All best practices for MQ apply to you. To name a few (but in no way a complete list):-

• Ensure you have good security practices - take a look at the RedBook: Secure Messaging Scenarios with WebSphere MQ
• Ensure you have data conversion used by all your applications from the start whether you think you need it or not, with that mix, you will need it
• Have a good naming convention. Read Naming Convention for MQ objects

There are a collection of Best Practices articles which Roger has pulled together here: Information on MQ Best Practices. Read all that are available (some are broken links now which is a shame). Then come back to the forum and ask about anything you don't understand the reason for.

If you can tell us more about your MQ network, we might be able to give more specific answers.

Cheers
