Enabling the Diameter Console Extension

Configuring Diameter Client Nodes and Relay Agents 10-7 ■ SCTP can be used only for Diameter network traffic; SIP traffic cannot use a configured SCTP channel. ■ TLS is not supported over SCTP. In addition, Oracle WebLogic Communication Services only supports SCTP channels on the following software platforms: ■ Red Hat Enterprise Linux 4.0 AS, ES, WS Kernel 2.6.9, GCC 3.4 or higher on 32- or 64-bit hardware ■ Sun Solaris 10 on SPARC SCTP channels can operate on either IPv4 or IPv6 networks. Section 10.5 describes how to create a new SCTP channel. To enable multihoming capabilities for an existing SCTP channel, specify the IPv4 address 0.0.0.0 as the listen address for the channel or use the :: address for IPv6 networks.

10.6 Configuring Diameter Nodes

The Diameter node configuration for Oracle WebLogic Communication Services engines is stored in the diameter.xml configuration file domain_ homeconfigcustomdiameter.xml. If you want to provide diameter services client, server, or relay functionality on an engine tier server, you must create a new node configuration and target the configuration to an existing engine server instance. Diameter node configurations are divided into several categories: ■ General configuration defines the host identity and realm for the node, as well as basic connection information and default routing behavior. ■ Application configuration defines the Diameter applications that run on the node, as well as any optional configuration parameters passed to those applications. ■ Peer configuration defines the other Diameter nodes with which this node operates. ■ Routes configuration defines realm-based routes that the node can use when resolving messages. The sections that follow describe how to configure each aspect of a Diameter node.

10.6.1 Creating a New Node Configuration General Node Configuration

Follow these steps to create a new Diameter node configuration and target it to an existing Oracle WebLogic Communication Services engine tier instance: 1. Log in to the Administration Console for the Oracle WebLogic Communication Services domain you want to configure. 2. Click Lock Edit to obtain a configuration lock. 3. Select the Diameter node in the left pane of the Console. 4. Click New in the right pane to create a new Diameter configuration. 5. Fill in the fields of the Create a New Configuration page as described in Table 10–3 , then click Finish.
