They are both the same QM - there is no active QM and standby QM.
Non persistent messages do not survive a QM crash, regardless of whether its a HA QM or not. You can set a q attribute that will preserve non persistemt mesages if the QM is ended normally.

Sorry - not sure why/how the duplicates happened. Would a passing mod please delete this and the duplicates as I can't see a way to do it. Thank you.
EDIT: Also my first post on this thread please, as I didn't get to finish what I was typing and PeterPotkay did!

| So, it means there are no any chance to keep non-persist message when QM crash? Thanks a lot... |

You can't rely on keeping a non-persistent message even if the queue manager doesn't crash - that's the point!
If you want to be certain you'll retain a message, make it persistent.

Read the definition of a non-persistent message in the WMQ Application Programming Reference and WMQ Application Programming Guide.
