Item descriptors that specify locked caching must disable query caching by setting their query-cache-size attribute to 0.

A repository with item descriptors that use locked caching must be configured to use a ClientLockManager Component; otherwise, caching is disabled for those item descriptors. The repository’s lockManager property is set to a component of type atg.service.lockmanager.ClientLockManager.

At least one ClientLockManager on each Oracle ATG Web Commerce instance where repositories participate in locked caching must be configured to use a ServerLockManager.

A ServerLockManager Component must be configured to manage the locks among participating Oracle ATG Web Commerce instances.
