Yup.

Yeah, by MQ I meant WebSphere MQ (the successor to MQSeries). > If you are using JMS (and I have no idea why you wouldn't) then > switching providers isn't an issue (IME) sure a bit of config > changes but the core code and principles remain the same. Interesting. Not an "issue" per se, but was your experience without incident in terms of anything provided by the underlying provider that didn't work the same with the new provider? SQL, of course, is supposed to provide DB independence if you're careful. I view JMS similarly. Has your experience shown otherwise? I know it's off-topic for this forum but I'd be interested in hearing any issues/non-issues you've encountered. -Rob
