6.2.10 Scaling the Topology

You can scale out and scale up an Oracle ADF 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.

6.2.10.1 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 Oracle ADF. The node contains a Middleware home in shared storage. You can use the existing installations Middleware home, and domain directories for creating new servers. There is no need to install Oracle Fusion Middleware binaries in a new location, or to run pack and unpack. Follow these steps for scaling up the topology: 1. Using the Oracle WebLogic Server Administration Console, clone WLS_ADF1 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: Configuring High Availability for Oracle ADF and WebCenter Applications 6-29

a. Select Environment Servers from the Administration Console.

b. Select the managed server that you want to clone.

c. Select Clone.

Name the new managed server WLS_ADFn, where n is a number to identify the new managed server. 2. For the listen address, assign the host name or IP to use for this new managed server. 3. Ensure that the port number for this managed server is available on this node. 4. Reconfigure the Oracle HTTP Server module with the new member in the cluster. See Section 6.2.9.5, Configuring Oracle HTTP Server for the Administration Server and Oracle WebCenter Managed Servers.

6.2.10.2 Scaling Out the Topology Adding Managed Servers to New Nodes

In scaling out your topology, you add new managed servers configured with Oracle ADF applications to new nodes. Before performing the steps in this section, check that you meet these requirements: ■ In your topology, there are existing nodes running managed servers configured with ADF applications. ■ ADF managed servers are clustered and the new managed server will also be part of that cluster. ■ The new node can access the existing home directories for WebLogic Server. You use the existing installations in shared storage for creating a new managed server. There is no need to install WebLogic Server binaries in a new location, although you must run pack and unpack to create a managed server domain. Follow these steps for scaling out the topology:

1. On the new node, mount the existing Middleware home, and ensure that the new

node has access to this directory, just like the rest of the nodes in the domain.

2. To update the Middleware home list, create or edit, if another WebLogic

installation exists in the node the MW_HOMEbeabeahomelist file and add ORACLE_BASEproductfmw to it. 3. Log into the Oracle WebLogic Administration Console. 4. Create a new machine for the new node that will be used, and add the machine to the domain. 5. Update the machines Node Managers address to map the IP of the node that is being used for scale out. 6. Use the Oracle WebLogic Server Administration Console to clone WLS_ADF1 into a new managed server. Name it WLS_ADFn, where n is a number and assign it to the new machine. 7. For the listen address, assign the host name or IP to use for the new managed server. 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.
