3-18 Oracle Fusion Middleware Administrators Guide for Oracle Web Cache In addition, see the following information about configuring clusters: ■ Section 3.7.5, Removing Caches from a Cluster ■ Section 3.7.6, Configuring Administration and Invalidation-Only Clusters To configure a cache cluster for a configuration in which the caches are associated with same Oracle WebLogic Server, follow the instructions in Section 3.6 to use Fusion Middleware Control to configure the cluster.

3.7.1 Task 1: Configure Cache Cluster Settings

To configure settings for a cache cluster with Oracle Web Cache Manager:

1. From Oracle Web Cache Manager, in the navigator frame, select Properties

Clustering . See Section 2.7.2 . The Clustering page appears. The General Cluster Information section displays the default clusterwide values for failover and invalidation synchronization. The Cluster Members table displays the current cache the cache to which you are connected as the only cluster member. Oracle Web Cache ignores the cluster information if there is only one cluster member.

2. In the General Cluster Information section of the Clustering page, click Edit.

The Edit General Cluster Information dialog box appears. 3. In the Cluster Name field, enter a name for the cluster. 4. In the Failover Threshold field, enter the number of allowed consecutive request failures before Oracle Web Cache considers another cache cluster member to have failed. The default is five failures. See Section 3.6.2 for further information about this field.

5. In the Ping URL field, enter the URL that cache cluster members uses to attempt to

contact a cache cluster member that has reached its failover threshold. Use a URL that is cacheable and that you can guarantee is stored in each cache. The default is _oracle_http_server_webcache_static_.html, which is stored in the cache.

6. In the Ping Interval field, enter the time, in seconds, between attempts by a cluster

member to reach the failed cluster member. The default, 10 seconds, is a reasonable interval for most situations.

7. In the Propagate Invalidation field, select Yes or No to specify whether you want

all invalidation requests from any cache cluster member to be synchronized with other cache cluster members.

8. Click Submit.

9. In the Cluster Members table of the Clustering page, default values are displayed for the current cache. Select the cache and click Edit Selected. The Edit Cluster Member dialog box appears.

10. In the Cache Name field, enter a name for the Oracle Web Cache instance. The

name must be unique from the names of other caches in the cache cluster.

11. By default, the Host Name field contains the host name of the node on which

Oracle Web Cache is installed. Usually, you do not have to modify this field.
