This section tells you about using the WebSphere Service Registry and Repository (WSRR), either to manage service endpoints or to manage mediation-policies.
Mediation flows can use WSRR as a dynamic lookup mechanism, providing information about service endpoints or mediation-policies.
To configure access to WSRR, you create WSRR definition documents using the administrative console. Alternatively, you can use the WSRR administration commands from the wsadmin scripting client. A WSRR definition and its connection properties is the mechanism used to connect to a registry instance, and retrieve a service endpoint or mediation-policy.
You can use WSRR to store information about services that you already use, that you plan to use, or that you want to be aware of. These services might be in your systems, or in other systems. For example, an application can use WSRR to locate the most appropriate service to satisfy its functional and performance needs.
When you develop an SCA module that needs to access service endpoints from WSRR, you must include the Endpoint Lookup mediation primitive in the mediation flow. At run time, the Endpoint Lookup mediation primitive obtains service endpoints from the registry.
When you develop an SCA module that needs to make use of a mediation-policy, you must include a Policy Resolution mediation primitive in the mediation flow. At run time, the Policy Resolution mediation primitive obtains mediation-policy information from the registry.
