I'm testing MQ v6 on my z/OS sandbox. After attending the 2006 MQ Conference, I though I heard that nonpersistent message would stay in their queues as long as the restart was a normal one. How is that controlled? I don't see a QLocal attribute to set in the DOC unless I missed it. Maybe this was for a future release? Is this the new default behavior? Hope not.

No, that's not quite right.

You can change the NPMCLASS of the queue to indicate that non-persistent messages should be preserved. I don't believe it's the default.

I don't know if NPMCLASS is supported on z/OS.

the attribute is NPMCLASS and the default is set to NORMAL so it matches the normal behaviour of non-persistent messages NOT surviving a restart...
