Object cache instance collection

Use this page to configure and manage object cache instances, which in addition to the default shared dynamic cache, can store, distribute, and share data for Java™ Platform, Enterprise Edition (Java EE) applications. Use cache instances to give applications better flexibility and tuning of the cache resources.

Use the DistributedObjectCache programming interface to access the cache instances. For more information about the DistributedObjectCache application programming interface, see the API documentation.
