We are conducting a proof of concept trying to connect Websphere Studio applications to a queue manager on MVS for the purpose of using the MQ CICS bridge. I have several areas of confusion.
From what I've read it appears we need SRVCONN channels defined (but I'm not sure of this).
A client connect component needs to be installed on the mainframe because it does not come with MQ/ESA so we cannot connect directly to the mainframe qmgr.
To get around that restriction, I want to set up the connection to a UNIX qmgr and define the request queue remotely so that the messages end up in MVS with the respone queue being local to the UNIX qmgr.
My questions to anyone who has done is are:
Do we really need a client/server connection channel set up, or is there another way of doing this?
Once messages are written to the reply queue, how does the Websphere application pick them up?
Does anyone know where to find easy to follow documentation with basic "how to" samples?
Thanks in advance.

If you want your program to connect to the MVS queue manager, you'll do it as a client (ie, CLNTCONN/SVRCONN channels) and you'll need to have the Client Access Facility installed on MVS.
If you want your program to act as a client to a Unix queue manager, you can do this. You could then use remote message (ie, REQUESTER, SERVER, etc. channels) to get messages from Unix to MVS and back.
As far as which to use, I've seen people do both. |

There are two types of setup. 1) You can put and get message directly from queue manager in MVS. 2) You can put and get message directly from queue manager in UNIX or any other OS, and let MQ does the forwarding messages to and from MQ manage on MVS.
For setup 1, you need to have server connection set up on MVS queue manager. No need for receiver/sender channels.
For setup 2, On UNIX, define remote queue defn (RQ1) of MVS target queue, setup transmission queue and sender channel on UNIX, and receiver channel and target queue (Q1) on MVS. Here names of sender and receiver channels should be same. Now, Create local response queue (Q2) on UNIX. Then define remote q defn (RQ2) of UNIX response q (Q2)on MVS, and transmission and sender channels on MVS. Finally setup receiver channel on UNIX. Here names of sender and receiver channels should be same.
