The invalidateExternalCacheOnFullInvalidate property controls whether the cache invalidation service and explicit cache invalidation will affect the externally cached data for a repository component. See Cache Invalidation Service.

Use this property to reduce the number of invalidation messages that your Oracle ATG Web Commerce server cluster sends to your external distributed cache application. If you have several Oracle ATG Web Commerce servers, allow a small number of them to invalidate the external cache as needed and set this property to false for the rest.

This property controls whether the external cache for a repository is affected by either full cache invalidation, selective cache invalidation, or calls to the invalidateCaches() method for a repository.
