Greetings.

I have a cluster of 4 qmgrs, so I defined a svrconn channel on each qmgr and then 4 client connection channels corresponding to each svrconn channel. They all use a unified name APPQM in the qmgr name field. I then copied the CCTD file and distributed to the client, thinking it will shield the client from having to know the individual qmgr names.

But the client is getting MQRC 2058.

What could I have missed here? Is this the way the client supposed to use the CCTD file?

thanks a lot!

Is the app using APPQM or *APPQM as the symbolic name?

Yes. that symbolic name get resolved to the real qmgrname through the CCTD file, correct?

APPQM and *APPQM are different, so which is it you're using?

If the app MQCONNects to '*APPQM' the CCDT table will be searched for any CCDT entry that matches 'APPQM'. There will be no check for the actual queue manager name.

So, if the real qmgrs are APPQM01, APPQM02, APPQM03, APPQM04, then I should put "APPQM*" in the QmgrName field?

So, I completely misunderstood the resolution mechanism in the CCTD.

thanks so much for pointing that out!

No, put *APPQM !

No. Put APPQM in the queue manager name field of the CCDT. Put *APPQM in the application MQCONNect call.

Seems so.

Thanks for all the input.

I'm still getting 2058, and wonder if the QMNAME field in the client connection channel should contain the real queue manager name (APPQM01, APPQM02, etc) or can be an identical alias name across all CLNTCONN channels, like APPQM, in this CCTD file.

You can use the symbolic name or leave the attribute blank.
