Configuring High Availability for Oracle Fusion Middleware SOA Suite 5-193

5.14.22 Scaling the Topology

You can scale out or scale up this high availability topology. When you scale up the topology, you add new managed servers to nodes that are already running one or more managed servers. When you scale out the topology, you add new managed servers to new nodes.

5.14.22.1 Scaling Up the Topology Adding Managed Servers to Existing Nodes

In this case, you already have a node that runs a managed server configured with SOA and Oracle Service Bus components. The node contains a Middleware home, an Oracle HOME SOA and Oracle Service Bus and a domain directory for existing managed servers. You can use the existing installations the Middleware home, and domain directories for creating new WLS_OSB servers. There is no need to install SOA or Oracle Service Bus binaries in a new location, or to run pack and unpack. For scaling up the SOA Servers, follow the steps in Section 5.13.22.1, Scaling Up the Topology Adding Managed Servers to Existing Nodes. Follow these steps for scaling up the topology for the OSB server: 1. Using the Administration Console, clone WLS_OSBn into a new managed server. The source managed server to clone should be one that already exists on the node where you want to run the new managed server. To clone a managed server:

a. Select Environment - Servers from the Administration Console.

b. Select the managed server that you want to clone for example, WLS_OSB1.

c. Select Clone.

Name the new managed server WLS_OSBn, where n is a number to identify the new managed server. The rest of the steps assume that you are adding a new server to OSBHOST1, which is already running WLS_OSB1. 2. For the listen address, assign the virtual host name to use for this new managed server. If you are planning to use server migration as recommended for this server, this virtual host name will enable it to move to another node. The virtual host name should be different from those in use by other managed servers may be in the same or different domain that are running in the nodes used by the OSBSOA domain. Perform these steps to set the managed server listen address: a. Log into the Oracle WebLogic Server Administration Console.

b. In the Change Center, click Lock Edit.

c. Expand the Environment node in the Domain Structure window.

d. Click Servers. The Summary of Servers page is displayed. e. Select the managed server whose listen address you want to update in the Names column of the table. The Setting page for that managed server is displayed. f. Set the Listen Address to OSBHOST1VHN1.

g. Click Save.

5-194 Oracle Fusion Middleware High Availability Guide h. Save and activate the changes. The changes will not take effect until the managed server is restarted. 3. Update the cluster address to include the new server:

a. Select Environment - Cluster from the Administration Console.

b. Click on the OSB_Cluster server. The Settings Screen for the OSB_Cluster appears.

c. In the Change Center, click Lock Edit.

d. Add the new servers address and port to the Cluster Address field. For example: OSBHOST1VHN1:8011,OSBHOST2VHN1:8011,OSBHOST1VHN2:8011 4. If your Oracle Service Bus configuration includes one or more business services that use JMS requestresponse functionality, then you must also perform the following procedure using the Oracle Service Bus Console after adding the new managed server to the cluster:

a. In the Change Center, click Create to create a session.

b. Using the Project Explorer, locate and select a business service that uses JMS requestresponse. Business services of this type display Messaging Service as their Service Type.

c. At the bottom of the View Details page, click Edit.

d. If there is a cluster address in the endpoint URI, add the new server to the cluster address. e. On the Edit a Business Service - Summary page, click Save. f. Repeat the previous steps for each remaining business service that uses JMS requestresponse.

g. In the Change Center, click Activate.
