Hi everyone,
Currently, we are trying to connect cloverleaf engine(application on which the mq client version is installed) to Z/OS queue manager on which it has a remote queue that has a local queue on AIX BOX(here the broker exits) basically, where the transformation is done and the message goes into a local queue back on Z/OS from where SAP XI picks up the message and save it in SAP BAPI. The issue is cloverleaf looks like it is connected which is shown on Z/OS side but the state on cloverleaf engine shows as initializing but never connects, which basically does not allow to put messages on queue. Clover leaf on its script side(while connecting to the queue manager on Z/OS) creates a dynamic queue on Z/OS. but where as the same process works when the Z/OS is not in the picture and cloverleaf connects directly to AIX. Company wanted to use Z/OS as the source not AIX. Can anybody suggests any solution where we can get this happening using Z/OS.
solutions related to connecting to AIX directly are available. we need something that uses z/OS as the source?  crisis situation please advice. |

Depending on where it lives and how it connects you may need the client attachement facility.(CAF).
This is quite expensive and you might want to rethink your strategy and keep cloverleaf connecting to AIX...

Also, security on zOS qmgrs is fairly advanced and can be a source of a lot of effort.
You may want to verify that the user that cloverleaf is using has the necessary permissions to create and work with dynamic queues, and connect, and all of the other things that it needs to do.

Not that I would have the CloverLeaf MQ client on z/OS, I would bet that the Cloverleaf exception is a security exception. Look in the CHIN and MSTR logs of your MF queue manager and see if that is true.
I prefer the Cloverleaf SW be a client to and AIX node and route the data to MF. I am sure they have their reasons.

Run - that was a joke referring to another thread.
My idea remains "check security", and thankfully belchman (who has more experience with zOS than I do, since belchman knows that CHIN has a log...) agrees.

As run looks to connect directly to the MF and ditch the Distributed qmgr I sincerely hope that they have the CAF at his site...

If that weren't the case, then it would ssem unlikely that " looks like it is connected which is shown on Z/OS side ".

can you establish any client connection to the zOS queue manager from another machine?
If so, the CAF is installed and working.
If not, you need to ask the mainframe MQ administrator if they have the CAF installed.
If they don't, then you need to either BUY it, or use a different qmgr.

Glad we have the CAF issue out of the way.
Now is there any way you can get an MQtrace on the client connection from cloverleaf?
Could it be that cloverleaf is failing some initialization that has nothing to do with MQ?

Just a point, if you look at the startup of your z/OS xxxxCHIN and don't see this:
+CSQX011I &MQD0 CSQXGIP Client attachment feature available
Then the CAF isn't installed.
Send me your credit card number and I'll get it for you  |
