ABSTRACT:
In one embodiment the present invention includes a method and system for managing cache invalidation. In one embodiment, connection information to a database in stored in an intermediate cache management module. If changes are made to objects in the database, the objects are invalidated in a local cache. The connection information is accessed and used to connect to the database by an invalidation listener. The invalidation listener may determine the changes so that the changes can be reflected in the cache. Embodiments of the present invention may be implemented across multiple nodes in a clustered environment for updating caches on different nodes in response to changes to data objects performed by other nodes.
