Java Messaging Service (JMS)

When configuring the Java Messaging Service (JMS) and Store and Forward (SAF) services, we will typically need to configure some or all of the following resources:

  • JMS Servers - We will typically want to define a JMS Server for each managed server instance in the targeted cluster. Each JMS Server will need to be pinned to a separate managed server in the cluster.

  • Persistent Store - We will need to define a dedicated persistence store for each JMS Server. See Configuring Persistent Stores for further details.

  • JMS Module - We will typically define a JMS Module targeted at a specific cluster. This acts as a configuration container for JMS Resources, such as:
    • Sub Deployment - We will typically define one sub deployment per JMS Module and target it to the set of JMS servers running on the WebLogic Server cluster targeted by the JMS Module
    • Connection Factories - Used to create a connection with a JMS provider (i.e. queue or topic).
    • Uniform Distributed Queue - A JMS queue for a JMS server
    • Uniform Distributed Topic - A JMS Topic for a JSM server
  • SAF Providers
    • SAF Agents - which perform the actual work of store and forward of JMS messages at runtime
    • Remote SAF Contexts - which encapsulate the configuration required to connect to a remote JMS provider
    • SAF Error Handling - which encapsulates specific behavior used to process messages in the event of an error
    • SAF Imported Destinations - which encapsulate the configuration for specific remote JMS queues that an SAF Agent will interact with
