We currently have most of our applications running on 7.1.8. We're looking to start using 7.2.2. However, there has been some debate among our infrastructure team as to whether 7.2.2. can work with older versions of IBM MQ. I can't see anything in the platform support or update guides about MQ versions. Can anyone shed any light on this, please?
Thank you for your reply, Narasimha. However, I'm still a little confused. You say MQ9 will support 7.2.2, but I'm after the opposite side of the answer, that is: what versions of MQ can I use with 7.2.2? Can I still use MQ8 with 7.2.2?
and read into the article something which was not meant.
Namely, where the article says: "For Pega 7.2.2, use the IBM MQ V9.0 client libraries..", it is ambiguous as to meaning.
The information which I have received from Engineering is that this is NOT meant to say that one can ONLY use MQ V9.0.
Instead, the version of the MQ client libraries installed in the Pega classpath determines the version compatibility with the MQ server. The PDN article recommends V9.0 of the client libraries because that will be backwards-compatible with all versions of WebSphere MQ from 9.0 down.
So you can use the same MQ 8.x libraries as now with 7.2.2 to communicate with an MQ 8 server.
The other information is If you are running Pega in a WAS container, there’s nothing to install. If you are running Pega in a different app server, you need to download and install the appropriate MQ client JARs."
