You are setting up a GridLink Datasource. What function will help you to seamlessly connect to a dynamic oracle RAC installation

The Single Client Access Name (SCAN) is a core feature of Oracle Real Application Clusters (RAC) that provides a single, stable hostname for clients to connect to the database. When setting up a GridLink Datasource, the JDBC URL should use the SCAN address. This decouples the client connection information from the specific nodes in the cluster. The SCAN listeners then redirect connection requests to the least-loaded, available instance. This architecture is essential for seamless connectivity to a dynamic RAC environment where nodes may be added or removed without requiring client-side configuration changes.

A. Simple Connection Access Node: This is not a standard or recognized term within Oracle RAC or WebLogic Server architecture.
B. Single Connection Anonymous Network: This is a fabricated term that combines unrelated networking and database concepts.
C. Simple Client Address Name: This is an incorrect and non-standard term; the correct feature name is Single Client Access Name.

"Introduction to Oracle RAC". Section: "Single Client Access Name". This section defines SCAN as "a single name that resolves to three IP addresses in the Domain Name System (DNS)... Using SCAN to connect to the cluster provides location independence for the database."

"Using Oracle RAC Features with JDBC". Section: "Connecting to Oracle RAC Nodes Using a SCAN". This guide explains

"Oracle recommends that you use a Single Client Access Name (SCAN) to connect to an Oracle RAC database... This removes the need to reconfigure the client when nodes are added to or removed from the cluster."
