Hi All,
I have more then 10 servers which are connected to MQ manager. All these servers are using client side API's and binding. For to use client side API's I need to create a channel.

Can anyone tell me if I will use one channel for all server ? or I need to make different channels for each server.

As I understood about channel, channels are logical edentity.

No, channels are the syncronous link between a given queue manager and a client. Each queue manager will need to have the correct configuration to support a client connection and each client will need to be provided with the correct connection information to attach to it's queue manager (where this may not always be the same queue manager, e.g. fail over when queue manager fails)

You should really create one channel for each application - ideally for each application on each server.

This way if a specific application has communications problems, or is doing something like opening lots and lots and lots and lots of connections, you can a) tell which one, b) work with it specifically rather than impacting everyone else.
