Dear all,

my understanding is that WPC is relying on internal MQ queues as a notification mechanism between multiple instances of the WPC servers running within the same WAS cluster.

Does anyone know if those MQ messages are persistant or not?

Thanks for your help,

Didier

Not sure, but most likely they would be persistent.
What does the doc say
What does the default persistence on the queue set to
I don't have a WPS right now but when I go home I can sure check and try to answer
BTW, which version?

Thanks for your asnwer!

I just checked the MQ scripts provided and the queues are set to persistent (version 5.1.1.4).

Oh OK
The reason I asked for version is recently, I was working on the new process server and I used SIB instead of real MQ and found that the messages that are put onto SIB survived a server restart. So, they were persistent too.

Have fun
