JMS

In the JMS area of the Administration Console, you can configure and monitor JMS servers, connection factories, destinations (physical queues and topics), distributed destinations (sets of physical queue and topic members within a WebLogic Server cluster), destination templates, destination sort order (using destination keys), persistent stores, session pools, and connection consumers.

You can also accomplish the following tasks:

• Set up custom JMS applications.

• Define thresholds and quotas.

• Enable any desired JMS features, such as server clustering, concurrent message processing, destination sort ordering, persistent messaging, message paging, message flow control, and message load balancing.

JMS Server Tasks

A JMS server manages connections and message requests on behalf of clients. You must first configure a JMS server before you can configure any destinations or consumers.

Create a JMS Server

1. Expand the JMS node and the Servers node. The JMS Servers table displays in the right pane showing all the JMS servers defined in your domain.

2. Click the Configure a new JMS Server text link. A dialog displays in the right pane showing the tabs associated with configuring a new JMS server.

3. On the Configuration General tab, enter values in the Name, Store, Paging Store, and Temporary Template attribute fields. For more information about JMS server general attributes, see Attributes.

4. Click Create to create a JMS server instance with the name you specified in the Name field. The new instance is added under the JMS Servers node in the left pane. A Destinations node and a Session Pools node are automatically added under the new server instance by default.

5. On the Configuration Thresholds & Quotas tab, enter values in the Bytes and/or Messages Maximum, Threshold, and Paging attribute fields. For more information about the Thresholds & Quota attributes, see Attributes. Click Apply to save your changes.

6. On the Targets tab, target a server target instance or a migratable target on which to deploy the JMS server, as explained in Assign a JMS Server.

7. Click Apply to assign the JMS server.

Clone a JMS Server

1. Expand the JMS node and the Servers node.

2. The JMS Servers table displays in the right pane showing all the JMS servers defined in your domain.

3. Click the Clone icon in the row of the JMS server that you want to clone. A dialog shows the tabs associated with cloning a JMS server.

4. On the Configuration General tab, enter values in the Name, Store, Paging Store, and Temporary Template attribute fields. For more information about JMS server general attributes, see Attributes.

5. Click Create to create a JMS server instance with the name you specified in the Name field. The new instance is added under the JMS Servers node in the left pane. A Destinations node and a Session Pools node are automatically added under the new server instance by default.

6. On the Configuration Thresholds & Quotas tab, enter values in the Bytes and/or Messages Maximum, Threshold, and Paging attribute fields. For more information about the Thresholds & Quota attributes, see Attributes. Click Apply to save your changes.

7. On the Targets tab, assign the JMS server to a server target instance or to a migratable target.

   For more information, see Assign a JMS Server.

Assign a JMS Server

1. Under the JMS Servers node in the left pane, click the node for the JMS server instance that you want to assign. A dialog displays in the right pane showing the tabs associated with this instance.

2. Click the Targets tab.

3. Complete the following steps for the Servers and/or Migratable Servers tabs:

   1. Servers tab—On the Targets list, select the server target where you want to deploy the JMS server. When a target WebLogic Server boots, the JMS server boots as well. If no target WebLogic Server is specified, the JMS server will not boot.

   2. Migratable Servers tab—On the Targets list, select the migratable target where you want to deploy the JMS server. Migratable targets define a set of WebLogic Server instances in a cluster that can potentially host an exactly-once service, such as JMS. When a migratable target server boots, the JMS server boots as well on the user-preferred server in the cluster. However, a JMS server and all of its destinations can migrate to another server within the cluster in response to a server failure or due to a scheduled migration or system maintenance.

JMS Distributed Destination Tasks

You can configure multiple physical JMS destinations as members of a single distributed destination set that can be served by multiple WebLogic Server instances within a cluster. Once properly configured, your producers and consumers are able to send and receive to the distributed destination. WebLogic JMS then distributes the messaging load across all available physical destinations within the distributed destination. When a physical destination becomes unavailable, traffic is then redirected toward other available physical destinations in the set.

Warning: In general, BEA highly recommends deploying a distributed destination homogeneously across the cluster using similar configurations for each participating JMS server and it's associated physical destinations. This includes issues like ensuring that there are identical security permissions on all participating distributed members, or if persistent messaging is configured, ensuring that all members are associated with a JMS store.
