I am looking for "how-it-works" information regarding MQ for Linux running on z-Series box.
Does anyone know of any docs to point me to, to discover how this will work?
I need to know things like:
Can a z/OS qmgr and a linux qmgr from on the same z-zeries box?
What happems to XXMSTR and xxCHIN tasks, etc?
What types of implementations any of you have where you are using Linux on mainframe?
We currently run only z/OS MQ on mainframe with no client connections to mainframe qmgrs. All client connections are via a distributed gateway.
Danke

Thanks Michael. I will take a gander.
I am still searching to the end of the Internet for other info.
The current poser I am wrestling with is...
Can we somehow replace our z/OS queue manager that acts as a service entry point into backend CICS business services? We have the CICS adapter running to look at init queues on z/OS and I am trying to determine if the CICS adapter will work with MQ on Linux in the same fashion.
If anyone knows that this thought process is a waste of time, please tell me so I will give up and I will concede that we will always need the z/OS qmgr to support triggering.

CICS has to talk to a local qmgr. Which means it cannot be a client to a zLinux system.
Think of a zLinux qmgr as identical to AIX, Windows, Solaris etc. It is the same code.
It happens to execute on the same physical box as z/OS (and can therefore use hipersockets for inter-qmgr channels). But apart from that, there's no relationship. |

No, you can't get the same functional interactions with CICS from a queue manager running on zLinux - as zLinux is an entirely separate LPAR.
CICS would have to establish a client connection to the zLinux queue manager... and you'd therefore lose your transactionality. Plus, it's not really possible I believe.

Thank you Jeff and Mark...
It was becoming quite difficult to prove this not  ...

Which means both cics and the qmgr must be running in the same lpar.
