Configure external cache groups

 

Overview

The dynamic cache can control caches outside of the application server, such as the Edge server, an IBM HTTP Server, or an HTTP Server ESI Fragment Processor plug-in. When external cache groups are defined, the dynamic cache matches externally cacheable cache entries with those groups, and pushes cache entries and invalidations out to those groups. This allows WebSphere Application Server to manage dynamic content beyond the application server. The content can then be served from the external cache, instead of the application server, improving savings in performance.

 

Procedure

1. Open the administrative console.

2. Enable the dynamic cache.

   1. In the administrative console, click Servers > Application servers > servername > Container services > Dynamic cache service.

   2. Select Enable service at server startup to enable the dynamic cache each time the application server starts.

3. Define the external cache group that WebSphere Application Server should control.

   1. In the administrative console, click Servers > Application servers > servername > Container services > Dynamic cache service > External cache groups.

   2. Click New or choose an external cache group from the list.

4. Configure cache group members.

   1. Click External cache groups from the dynamic cache administrative console page. Then click New or choose an external cache group from the list.

   2. Click External cache group members > New or choose an external cache group member from the list.

   3. Type the configuration string in the Address field.

   4. Type the adapter bean name in the Adapter Bean Name field.

   5. Save the configuration.

   6. Click Apply or OK.
