So if I understand this correctly, the single amqzlaa is being used for the Cluster repository, deferred message processor, command server, and channel initiator.
Why do these processes come up as shared, not fastpath
And if I start a listener now under MQ_CONNECT_TYPE=FASTPATH, I assume it will be trusted, even though there is a single instance of amqzlaa ? Is that correct ?
Thanks |

They are queue manager processes and IBM has coded them that way, for whatever reason.

Not the listener (your DIS CONN output did not show any connection from it), but yes, the amqrmppa threads will connect "trusted", I think.
Hopefully it would be quick for you to try it out. Please try it and tell us. |

I'm confused...
Were you contemplating running your application (not the listener) as trusted? |
Both |
To me this says your app is running on the same server as the QM, and connecting in Client mode via the Listner. If yes, forget all this trusted mode talk and switch your app to connect in good ol' fashioned bindings mode.
Running things in trusted fastpath mode made a lot more sense when computers were running with low memory and wimpy CPUs.
Non persistemt messages, connecting in bindings mode, using batches of messages, NOT connecting/opening/closing/disconnecting for each message - these things will make HUGE differences in performance. Trusted mode sets you up for someone killing the trusted app for whatever reason...and taking the QM down with it.
