Hi,

I am trying to configure a remote queue manager and local queue manager and I am using a sender and a receiver channel to establish the communication.

When I try to use the same names for both the channels, the communication is established and the status of both the channels becomes Running. But if I use different name for the channels, the communication is not established and I see the status of the sender channel to be as "Retrying".

I am using IBM MQ 6.0 on both the servers.

Kindly assist me and please give me some suggestions to configure the two servers with different names, if possibe.


Thanks and Regards,

Rama Krishna.

Sender and receiver channel pairs must have the same name.

Check out the Intercommunication manual for an explaination of channels, and suggested naming conventions.

Or post some more details on your requirement which leads you to need them to have different names, so we may offer alternative methods of achieving the same thing.

MQ requires that the channel pair (sender-receiver) have the exact same name; so this is working as designed.

The documentation suggests a channel name like QMA.QMB for both sender and receiver. QMA and QMB are the names of the queue managers. On QMA, the sender side, messages flow from QMA to QMB.
MQ doesn't care what you call your channels - any valid name will work.

Running state is a good thing. At channel attach, the channel ends compare channel definitions - they channel names, transport type (and a few other attributes) must match. Other channel attributes must be compatible. As Vitor notes, this is well documented in the MQ V6 Intercommunications manual.
