We would like to use AMS end to end, the starting end would be Datapower MQ client placing messages on a queue.

Apparently, although DP embeds the MQ v8 or V9 client code - it does not support use of AMS.

Seems a major oversight by IBM. I have seen a RFE about it - but hey guys this is 2022 - we can't wait for this.

This could distort our designs to use something less ideal such as message broker (in this case anyway).

Any thoughts?

I believe you should be able to define an AMS channel intercept for DP to create the message with a known user key defined in the channel intercept.
Use SSL from DP to the qmgr on the channel and the AMS intercept from the channel to the queue.

The AMS intercept runs on the MQ client platform (in this case DP) and therefore needs the keystore.conf to be configured and the appropriate certificates set up.

I have raised a support case with IBM and they say this is "not supported" and referred to a RFE from Peter Potkay.

You are suggesting not encrypting the message on the client but letting the QM encrypt the message - I don't think that is how AMS works with client applications.

If the queue had a AMS policy requring encryption (or signing) then I am fairly sure the MQPUT from DP would fail.

One could put it to an unprotected queue and then move it (with something) to a protected queue of course.

MCA intercept runs on the SVRCONN on behalf of the client, using certs that are configured at the server end. See https://www.ibm.com/docs/en/ibm-mq/9.2?topic=ams-mca-interception-example One of the main usage scenarios was for systems like datapower which did not have an AMS-enabled client.

The messages are still protected before actually getting on the queue.

Interesting - does this work if the QM is z/OS MQ?

Found this via google. z/OS Advanced mentions MCA and SVRCONN channels http://ibm-messaging.github.io/mqperf/MQ_for_zOS_V920_Performance.pdf

Can't see how to enable MQ MCA AMS under z/OS - but maybe some poor devil at IBM support will know.

z/OS qmgrs support AMS MCA intercept for qmgr/qmgr channels (eg sdr/rcvr), but not svrconns. Distributed qmgrs are the opposite. Maybe one day they'll line up but not at the moment.

zpat, sounds like you may need to have the DataPower appliances MQ Client connect to non z/OS MQ "Concentrator" queue managers which in turn send to the z/OS queue managers over QM to QM channels.

OK - z/OS strikes again - three strikes and I am out
