Hi All,
I have a client which needs to be connected to two different MQ Servers. Normally i can go for MQSERVER environment variable or AMQCHLTAB for connecting any one queue manager. In AIX i can export the variable for one time and connect to the MQ Server.
My question is...
I want to connect two MQ server by a MQ client. I cannot declare MQCHLLIB variable two times as it overwrites the previous value. How can i come over this problem?
To be more clear...
My client doesnt know client server set up.. He just wants to put some messages to queue on two different servers using the same client. he is not aware of exporting the variables to connect to the servers indicidually. How can i set these and make him to put the messages on both servers using same client???
Any inputs???? |

A client channel table with definitions of the two qmgrs that the application wants to connect to.
Usually, an application connects to one qmgr at a time. MQCMIT and MQBACK are based on the connection handle - if you intend to do UofW processing.

Yep, 2 differently named CLNTCONN channels, 1 for each qmgr.
A thread of the client prog can only connect to 1 qmgr at a time.

MQ Clients can connect to more than one QM in a single thread. Should they is another matter, but they can.

 er...what? The poster is discussing WMQ Client connecting to multiple queue managers, presumably simultaneously, so I don't think topology has a bearing on this.

This has nothing to do with the topic under discussion. Please stop posting random nuggets of possibly correct but irrelevant and/or misleading information.
