Perform this task so that your application can access dynamic
cache object cache instances with the DistributedMap or DistributedObjectCache
interfaces.
Before you begin
Before you begin, enable the dynamic cache service. See
동적 캐시 서비스 사용 for more information.
About this task
Using object cache instances can improve the performance
of your application because you can programmatically store and share
frequently used objects. By using object cache instances, you also
have the necessary control over the dynamic cache when you are running
multiple applications in an application server. See
캐시 인스턴스 for more information.
Procedure
- Configure one or more cache instances.
- In the administrative console, click Resources >
Cache instances > Object cache instances.
- Specify the scope for the cache instance.
Cell scope makes
the cache instance available to all servers within the cell. Node
scope makes the cache instance available to all servers on the particular
node. Cluster scope makes the cache instance available to all members
in a specified cluster. Server scope makes the cache instance available
to only the selected server. You can mix scopes, if necessary.
Node scope makes the cache instance available
to all servers on the particular node. Server scope makes the cache
instance available to only the selected server. You can mix scopes,
if necessary.
Note: You cannot create cache instances
(object or servlet) at different scopes with the same cache name or
JNDI name.
- Click Apply after changing the
scope.
- Click New.
- Enter the Java™ Naming
and Directory Interface (JNDI) name for this cache instance.
This
is name that you pass to the InitialContext lookup() method from within
your application. For example, services/cache/instance_one.
- Enter or modify other properties as needed.
- Update your application. To store and retrieve
objects in an object cache instance, you need a DistributedMap or
DistributedObjectCache reference for the named object cache instance.
See 동적 캐시에 DistributedMap 및 DistributedObjectCache 인터페이스 사용 for more information.
Results
You configured object cache instances that you can access
programmatically with the DistributedMap and DistributedObjectCache
interfaces.
What to do next

추가 API(Application Programming Interface) for

interfaces.
