I recently posted a question relating to JMS and connecting to multiple queue managers, via client connections.
"The customer wants a JMS application that can connect(as a MQ Client) to any of a number of queue managers in the cluster.
They do not want to specify or be required in their code to walk thru a channel tab file to determine which queue manager to use.
They want the MQ interface isolated from the in-house code."
Browsing PartnerWorld for Developers I found:
"Is there any way to use the MQSeries client connection table with JMS?
A: No, there is no way to define a connection factory to use the MQSeries client connection table.
Reference: F00036186 Date: 12 Dec 2001"
Can someone help clarify? Can JMS accomplish this?
thank you.

No. If you want JMS to try multiple Queue Manager connections, then this code would have to be implememted in the application.
With JMS, in Client mode, either the application is responsible for defining the connection parameters to the server or they must be picked up from a Connection Factory, where you can only define a single connection per Factory.
With the Client Connection table, you can specify a list of connections to be attempted, in order, until a sucessful connection is made. Unfortunately, this is NOT used by JMS.
Cheers,

They are also wanting to create connection pools to multiple queue managers, if possible. The current code is Java, but they have it in mind to convert to JMS.
I am trying to determine if this is a viable option.
Would they be better served to remain with Java and use the available MQ connectors? |
