Abstract
Techniques are provided for creating dynamic connections to objects on remote database clusters. Service-to-instance mapping information is provided to a listener process for a cluster database. The service-to-instance mapping indicates the current provider instance(s) of each object within the cluster database. To establish a connection to a remote object, a sending process uses an object link. The object link identifies the desired destination object, but not the provider instance of the object. The object link also contains a authentication information and other connection information that exists in regular database links. The global listener for the cluster database uses the service-to-instance mapping to determine which instance is the current provider of the specified object, and dynamically distinguishes the appropriate database instance as the endpoint of the connection.
