The JMS Module resources can be deployed on a particular JMS Server.
Standalone queues or topics can only be targeted to a single JMS server. Whereas, connection factories, uniform distributed destinations (UDDs), and foreign servers can be targeted to one or more JMS servers, one or more server instances, or to a cluster. Therefore, standalone queues or topics cannot be associated with a subdeployment if other members of the subdeployment are targeted to multiple JMS servers. However, UDDs can be associated with such subdeployments since the purpose of UDDs is to distribute its members to multiple JMS servers in a domain.
For this reason, in a WebLogic JMS Module we can define a subdeployment.
Each subdeployment has a particular target !!!
To see the subdeployments we have for a JMS Module, we can open the WebLogic Administration Console, go to the Domain Structure -> Services -> Messaging -> JMS Module. Click on a JMS Module and after that click on the "Subdeplyments" tab. On this page we can see the combination of subdeployments, resources and targets:
Click a subdeployment to see the possible targets for that subdeployment:
You can see that a target could be an Admin Server, a Managed Server, a WebLogic Cluster or a WebLogic JMS Server.
