Configuring High Availability for Oracle ADF and WebCenter Applications 6-39 The following sections contain more information on the runtime and configuration aspects of an Oracle WebCenter cluster.

6.3.2.1 Oracle WebCenter Applications

During Oracle WebCenter installation, the managed servers are provisioned with system libraries and ADF libraries. Table 6–5 lists the managed servers and the applications which run on them.

6.3.2.2 Oracle WebCenter Startup Order

When a managed server is started, applications and libraries are started in the following order: 1. Oracle System libraries, known as the JRF libraries. 2. Oracle ADF libraries. 3. Instrumentation applications, such as Oracle DMS. 4. Oracle WebCenter applications, shown in Table 6–2 The startup order is also the order of dependency. If a dependent component does not deploy successfully, a later component may not function correctly. Oracle WebCenter application startup is not dependent of the availability of external services such as the Oracle Discussions server, or other back-end servers.

6.3.2.3 Deploying Oracle WebCenter Application on a Cluster

For an Oracle WebCenter cluster deployment, such as the one shown in Figure 6–5 , follow these rules for the targeting of applications, libraries, and system resources: ■ Target applications and libraries to the cluster target. For example, target the WebCenter application to the Spaces cluster. ■ JDBC resources to the cluster target. Oracle WebCenter applications and the Oracle WebCenter Discussions server are deployed as Oracle WebLogic stage applications. During the initial deployment of each application, the deployment files are received from the Administration Server and deployed locally. Cluster Communications By default, each Oracle WebCenter cluster is configured as unicast. To configure your Oracle WebCenter cluster for multicast, see Oracle Fusion Middleware Using Clusters for Oracle WebLogic Server.
