Dynamic content can be served from the external cache, instead of the application server, which can improve performance. Use the WAS administrative console to set up external caching.

To configure external caching, perform the following steps:

  1. Start the WAS administrative console.

  2. Enable the dynamic cache.

    1. In the topology tree, expand...

      Servers | Application Servers | servername | Dynamic Cache Service

    2. Select the check box in the Startup state field to enable the dynamic cache.

  3. Define the external cache group for WAS to control.

    1. Click External Caching Groups on the Dynamic Cache administrative console page.

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

    3. Specify a name for the new cache, and click OK.

  4. Configure cache group members.

    1. Select the cache group to add members to.

    2. Click External cache group members.

    3. Click New.

    4. Type the configuration string in the Address field.

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

      For example, adapter bean names that are supported in WAS include com.ibm.ws.cache.servlet.Afpa (for AFPA) or com.ibm.websphere.servlet.cache.ESIInvalidatorServlet (for ESI).

    6. Click Apply or OK.

    7. Click Save to save the configuration.
