Start the DynaCacheEsi Application | Reconfigure web servers

External cache group settings

Define an external cache group...

1. Open the Network Deployment Manager administrative console and click...

   Servers | Application servers your_application_server | Container Services | Dynamic Cache Service | Additional Properties | External Cache Groups

   This panel allows you to create, delete, or update an existing external cache group.

2. The EsiInvalidator external cache group normally exists by default.

   If it is not shown, click New. This launches the Configuration window where you can specify the name of the external cache group.

   In a production environment, you need to verify, and, if necessary, create the external cache groups on all application servers that are serving the cached application.

   

3. On the cache group panel, click EsiInvalidator, then select External cache group members.

4. For the EsiInvalidator group, there should be one member by default.

   

5. If you just created the cache group, or if the default external cache group member does not exist, click New to create it, and specify the following information:
   • Address: localhost
   • Adapter Bean Name: com.ibm.websphere.servlet.cache.ESIInvalidatorServlet

   Then click OK.

6. If you have made any changes, make sure to save your changes to the master configuration.
