Abstract: Described herein is a system and method for providing a shareable global cache for use with a database environment. In accordance with an embodiment, a shareable global cache is used for caching connections to database instances. When a request is received for a particular service, the system looks for an idle connection to that service, and, if none is available, locates an existing connection to a database instance serving that service and switches a service on the existing connection to that service.
