PostForum:General Discussion Posted: Wed Jul 10, 2019 7:20 am Subject: Client Application Recommendation?
Not sure where this would be posted, and I couldn't find a reference to it anywhere.

I'm curious if anybody has a recommendation for a pre-built application opensource or paid, that will establish ...

Do you also receive a "flood" of response messages, with nearly all of them beyond your 20 second QoS time?

Ya. They send back a response for every message they receive, regardless of how ...

Why are you using the same channel/xmitq? Separating classes of traffic is very commonly done using multiple routes between the same qmgrs

It's configured like that for a lot of the connections &am ...

Just thought of a weird work-around...

I have a script that watches for when 3rd party channels are down, and will adjust clustered alias queues to have a lower priority when they're down (so not-d ...

I have a 3rd party that keeps complaining that every time our connection goes down, that we flood them with messages when the connectivity is restored, which causes a feedback loop that perpetuates a ...

PostForum:Clustering Posted: Tue Mar 19, 2019 1:58 pm Subject: Transmission Queue per Channel - not going away?
I have a cluster with a couple dozen partial repositories. And I have DEFCLXQ(CHANNEL) set. So it creates a new XMIT queue for every channel. I just find it easier to troubleshoot and resolve issues. ...

PostForum:IBM MQ Security Posted: Tue Mar 19, 2019 1:04 pm Subject: Default Certificate Question
One question - why did you set your 'real' cert to be the default? You should need to ever set any certificate to be the default. A default certificate may well get picked up when you don't intend it ...

PostForum:IBM MQ Security Posted: Fri Mar 15, 2019 7:46 am Subject: Default Certificate Question
Several years ago, before my queue managers were exposed to the filthy internet, I saw it coming and decided to learn a bit about how Certificates work with IBM MQ.

I set up a self-signed cert, set ...

Just so I'm not one of "those" people...

The problem has been resolved. Or at least we found a work around.

The problem was the Default Bind on my queues being set to 'On Group'. I don ...

I'm curious what kind of symptoms having a leaky memory in Cluster Cache would cause.
Well on the assumption that it's the same principle as any other memory leak, basically your program tells the OS ...

Ya. IBM L3 just got back to us, and they're going to have us do a dump.

This queue manager has "leaked" memory in the cluster cache shared
memory area. The most likely source (as i ...

I created a script that would create a unique clustered queue on every queue manager, then have all the other queue managers s ...
