Configure a JMS Module

A homogenous set of JMS servers is either a single JMS server that is meant to host non-distributed destinations, or a set of similarly configured JMS servers that each host the same distributed destination. Configure a JMS module and a single associated subdeployment for each homogenous set of JMS servers:

1. Create a system module. Target it to a single cluster (if using clusters) or a single WebLogic Server instance. You must always target the module even when leveraging subdeployments.

It is almost always preferable to use system modules instead of deployable

application modules. System modules can be created using the administration

console, the JMX API (Java MBeans), or WLST, there is no equivalent tooling for deployable modules. The only way to modify deployable modules is to manually edit the XML and redeploy.

2. Create exactly one subdeployment per module. Subdeployments are sometimes referred to as "advanced targeting" on the administration console. A single subdeployment aids simplicity - it's much easier for third parties to understand the targeting, and it reduces the chances of making configuration errors. If a single subdeployment is not sufficient, create two modules.

3. Populate the subdeployment only with JMS servers - not WebLogic servers. Only include the JMS servers that you wish to host destinations. This ensures that when the JMS resources are configured, they are targeted to the correct JMS servers. For modules that support non-distributed destinations, the subdeployment must only reference a single JMS Server. If you have a mix of distributed and non-distributed destinations, use two modules each with its own subdeployment.
