12 Configuring Coherence

This chapter describes the implementation and configuration of Oracle Coherence in Oracle WebRTC Session Controller.

Overview of WebRTC Session Controller Coherence Implementation

WebRTC Session Controller includes an implementation of Coherence used for all engine tier internal clusterwide communication and state management. The Domain Creation Wizard creates a default Coherence cluster for managing WebRTC Session Controller information automatically when setting up new domains. The default cluster include the servers included in the engine tier and the administrative server in your environment.

Configuring Coherence

You configure the WebRTC Session Controller Coherence implementation using the Oracle WebLogic Administration Console. See the chapter on "Configuring and Managing Coherence Clusters" in Administering Clusters for Oracle WebLogic Server for more information on the parameters that can be set in the Administration Console.

To configure the default Coherence cluster installed with WebRTC Session Controller:

1. Log in to the Administration Console for the WebRTC Session Controller administration server.

2. In the Domain Structure tree, expand Environment.

3. Select Coherence Clusters.

4. In the Coherence Clusters table, select defaultCoherenceCluster.

5. Configure the parameters for the Coherence cluster as needed.

6. Click Save.

Each engine tier server and the administration server acts as a managed Coherence server. See "Configuring Managed Coherence Servers" in Administering Clusters for Oracle WebLogic Server for more information about managed Coherence servers.

To configure Coherence settings for individual engine tier servers and the administration server:

1. Log in to the Administration Console for the WebRTC Session Controller administration server.

2. In the Domain Structure tree, expand Environment.

3. Select Servers.

   The Administration Console displays a list of servers included in your WebRTC Session Controller installation.

4. From the Servers table, select an engine tier or the administration server you want to configure Coherence settings for.

5. In the Configuration tab, select Coherence.

6. Configure the Coherence parameters for the server.

7. Click Save.
