Configure Store-and-Forward

The Store-and-Forward (SAF) service enables WebLogic Server to deliver messages reliably between applications that are distributed across WebLogic Server instances. If the destination is not available at the moment the messages are sent, either because of network problems or system failures, then the messages are saved on a local server instance, and are forwarded to the remote destination once it becomes available.

SAF agents are responsible for store-and-forwarding messages between local sending and remote receiving endpoints. A SAF agent can be configured to have only sending capabilities, receiving capabilities, or both. JMS SAF only requires a sending agent on the sending side for JMS messages. Whereas, WSRM SAF requires both a sending agent and a receiving agent.

To configure store-and-forward services:

  1. Start the Administration Server for your domain.
  2. Create Store-and-Forward agents.
  3. Optionally, optionally configure additional properties for a SAF agent, such as basic and advanced general properties, thresholds and quotas, or SAF log file rotation parameters.
  4. Optionally, configure a persistent store if you want a dedicated store for stored-and-forwarded messages. For more information about configuring a persistent store, see Configure persistent stores.
  5. Optionally, configure a Path Service if the sending-side is a cluster and the JMS producer is associated with a Unit-of-Order, which enables JMS message producers to group ordered messages into a single unit. See Create path services.

    For more information about JMS Unit-of-Order, see Using Message Unit-of-Order.

  6. Configure Store-and-Forward for JMS modules, as described in Configure JMS SAF.
