Why sub-deployments are used in WebLogic Servers
Ever wondered why sub-deployments are used for deploying JMS resources ?
- A sub-deployment is a mechanism by which JMS module resources like ‘queues, topics, and connection factories’ can be grouped and targeted to a server resource like ‘JMS servers, server instances, SAF agents, or a cluster’.
- You can group a connection factory with stand-alone queues or topics in a sub-deployment targeted to a specific JMS server, which guarantees that all these resources are co-located to avoid extra network traffic.
- Another advantage of such a configuration would be if the targeted JMS server needs to be migrated to another Weblogic server instance, then the connection factory and all its connections will also migrate along with the JMS server’s destinations.
