@Morag

Thx very much. There were many Google hits and some indicate this was introduced at 8.0.0.6 (so it has been around for a long time).

A friend said he read an article stating there was a new feature at MQ 9.2.2.0 where the Admin could change the expiry from -1 (never) to a value that does expire.

I suppose this can be done with t ...

Thanks markt,

Now I understand how that can work (and clearly does). I will do my homework on the AMS-Qmgr to non-AMS-Qmgr flow.

Often, there are old Qmgrs that cannot do AMS but need to play in ...

@MoragHughson OK, now that you mention and it makes sense that the AMS work is in the application space, I see that it does not matter if the Qmgr is using OAM or LDAP for AUTHRECs and such.

I have not had a chance to download just the MQ Client (not from the server media) and try AMS.

What I have expects the AMS files for the user at the MQ Client (errors in /var/mqm/errors files).

I'm wondering if the error message is really more like a warning message saying it is going to renegotiate the secret key?

I also wonder how many TLS records relate to how many bytes in the SSLRKEY ...

I would follow the IBM advice and avoid using GCM CipherSuites at TLS 1.2, if possible.

Hmmm, what IBM advice?
Where does IBM give that advice?

thx, Joseph

Managed .NET clients cannot change the SNI which is how MQ specifies a per-channel certlabel.

Yes. That is what was done. Going from LTS->CD works fine. You cannot go back, so back up the Qmgr first. I asked this same question.

CD is supported for 1 year from release or three more releas ...
