6.8 Troubleshooting Diameter Configurations

SIP Servlets deployed on Oracle WebLogic Server SIP Container use the available Diameter applications to initiate requests for user profile data, accounting, and credit control, or to subscribe to and receive notification of profile data changes. If a SIP Servlet performing these requests generates an error similar to: Failed to dispatch Sip message to servlet ServletName java.lang.IllegalArgumentException: No registered provider for protocol: Protocol The message may indicate that you have not properly configured the associated Diameter application for the protocol. See Section 6.6.2, Configuring Diameter Applications for more information. If you experience problems connecting to a Diameter peer node, verify that you have configured the correct protocol for communicating with the peer in Section 6.6.3, Configuring Peer Nodes . Keep in mind that Oracle WebLogic Server SIP Container tries only the protocol you specify for the peer configuration or TCP if you do not specify a protocol. 7 Oracle WebLogic Server SIP Container Base Platform Topologies 7-1 7 Oracle WebLogic Server SIP Container Base Platform Topologies The following sections provide an overview of the Oracle WebLogic Server SIP Container architecture and deployment topologies: ■ Section 7.1, Goals of the Oracle WebLogic Server SIP Container Base Platform ■ Section 7.2, Load Balancer ■ Section 7.3, Engine Tier ■ Section 7.4, SIP Data tier ■ Section 7.5, Geographically-Redundant Installations ■ Section 7.6, Example Hardware Configurations ■ Section 7.7, Alternate Configurations

7.1 Goals of the Oracle WebLogic Server SIP Container Base Platform

Oracle WebLogic Server SIP Container is designed to provide a highly scalable, highly available, performant server for deploying SIP applications. OWLSC is used for deploying any JSR 289 compliant SIP applications. The Oracle WebLogic Server SIP Container architecture is simple to manage and easily adaptable to make use of available hardware. The basic architecture consists of these components: ■ Section 7.2, Load Balancer ■ Section 7.3, Engine Tier ■ Section 7.4, SIP Data tier Figure 7–1 shows the components of a basic Oracle WebLogic Server SIP Container installation. The sections that follow describe each component of the architecture in more detail. 7-2 Oracle WebLogic SIP Server Container Administrators Guide Figure 7–1 Oracle WebLogic Server SIP Container Architecture
