Overview

Perform this task so that your application can access dynamic cache servlet cache instances. Using servlet cache instances can improve the performance of your application because one can store the output and the side effects of an invoked servlet. Servlet cache instances also give you the necessary control over the cache for multiple applications that are running in an application server.

Before you begin, enable the dynamic cache service.

 

Procedure

1. Enable servlet caching.

2. Configure one or more cache instances.

   1. In the administrative console, click...

      Resources | Cache instances | Servlet cache instances

   2. Specify the scope of the cache instance. Specify a scope of cell to make the cache instance available to all the servers that are in the cell. Node scope makes the cache instance available to all servers in a node. Server scope makes the cache instance available to the selected server only. If necessary, one can mix the scopes.

   3. Click Apply to save the scope.

   4. Specify the settings for the cache instance. The Name and JNDI name fields are required. The JNDI name is the name attribute that is specified in the <cache-instance> element in the cachepec.xml file. An example of a JNDI name that is specified in the cachespec.xml file follows

      <cache-instance name="services/cache/instance_one">
      

      In this example, specify services/cache/instance_one as the JNDI name.

3. Update your application. To use a servlet cache instance, specify a <cache-instance> element that has a name that is equal to the JNDI Name for this cache instance.
