Perform this task so that your application can access dynamic
cache object cache instances with the DistributedMap or DistributedObjectCache
interfaces.
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
Cache instances 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.
- 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 Using the DistributedMap and DistributedObjectCache interfaces for the dynamic cache for more information.
Results
You configured object cache instances that you can access
programmatically with the DistributedMap and DistributedObjectCache
interfaces.
