I have a suspicion that I may be asked to produce one of these in the near future, and would prefer not to dredge my memory for "bad practices" and "good practices", and miss lots of things as a result (especially in the Java side of things).

The second thing that goes as you get older is the memory, I can't remember what the first one is .

I wonder if any of you mavens out there have already produced such documents that I can use as inspiration.

Ideally this should cover both base MQI, Base Java, and JMS with examples of good stuff and bad stuff.

Any MQ admin dos and don'ts would be useful too.

Examples (stuff I can remember quickly)

DO use get w/convert when dealing with string data.

DON'T MQCONN, MQOPEN. MQPUT or MQGET one message, MQCLOSE, MQDISC (at least not normally). I've seen this create a very effective DoS attack on a CHIN when run from a multi-threaded client runing on multiple servers.

Do Use Bindings in preference to Client connections if you can (I know not really programming, but ...)

If you've anything you are prepared to share, please email it to:

Many thanks

Dave

If you are running JMS in stand alone USE a FILE context.
If you are running JMS in a J2EE server use the server's context. If the server's context does not have MQ setup use the File context to patch into the Server's context....

Enjoy

When dealing with string data, ALWAYS use GET with CONVERT option, and ALWAYS use PUT with STRING format.

Even if the source and target platforms use the same basic character set (eg. ASCII), there can be subtle differences between their actual code pages. And you never know, but one of the applications may get moved to a non-ASCII platform, such as z/OS.
