Enable dynamic caching

Use the dynamic cache service to improve the performance of cacheable objects. By default, the dynamic cache service is enabled.

Perform the following steps to enable dynamic caching:

1. Start the WAS administrative console.
2. In the topology tree, expand Servers and click Application Servers.
3. Click the server you want to enable dynamic cache.
4. Click Dynamic Cache Service.
5. Select Enable service at server startup in the Startup state field.
6. Click Apply or OK.
7. Save the administrative configuration.
8. Restart the application server.

For information about dynamic cache service settings, see DynamicCache service settings

When the number of cache entries reaches the configured limit for WAS, eviction of cache entries occurs. This allows new entries to enter the cache service. The dynamic cache service includes an alternative feature named disk offload, which copies the evicted cache entries to disk for potential future access.

For information on how to configure disk offload, see Configure disk offload caching.
