PostForum:IBM MQ Security Posted: Tue Sep 28, 2021 12:21 pm Subject: Java Client and ANY_TLS12_OR_HIGHER
It sounds like the gskit is doing a good job keeping up then with TLS 1.3.

I was surprised to see you have to go to Java 11 to get some TLS 1.3 support, and only some support at that. Not sure ...

In the testing I have done with IBM MQ and TLS 1.3, the Java side had to be at 11 to support TLS 1.3. I believe it was openJDK 11 that was supported, too. It looked like the openJDK 11 also only suppo ...

For the environment where you see mismatched jar versions, that does sound like there are back-leveled jars somewhere that are getting pulled into this client application. That could also explain the ...

I did a test at 9.2.0.1 on Linux I see similar behavior of a 2400 with a non-IBM JRE using useIBMCipherMappings=false and sslCipherSuite=ANY_TLS12_OR_HIGHER not working. However, switching the sslCiph ...

PostForum:General IBM MQ Support Posted: Fri Jul 02, 2021 4:16 am Subject: MQ Explorer SVRCONN channel status
Will a trace taken on the MQ client platform be of any use, if I send it to the IBM support centre?

(tracing on z/OS MQ really is most unfriendly to use and has to be sent as a dump to IBM).

z/OS does have an MQ API trace. It is not as user friendly as the Application Activity Trace, but you can see some of the API calls and control blocks (e.g. GMO) in this trace. The MH06 supportpac has ...

I am not saying that it is not JMS compliant to use the Session.createQueue method. However, the documentation for that method is warning that your application may become non-portable if you use it.

Passing the string through unchanged to the Destination creator IS 100% JMS compatible. Interpreting the URI string is up to the JMS provider to do.

What would not be standards-compliant is if the ...

JmsProducer has the following code for the -d option:

The Session.createQueue Java doc has the following blurb:

I believe your underlying requirement is validating that MQ is using the new certificate after a cert update. This link gives you an option with using openssl s_client.

By the same token I always put the full signer chain in the ...
