When an Oracle Commerce Platform application modifies an item that uses distributed TCP caching, the following occurs:
When the local repository item cache is updated, the repository looks up the specified item descriptor in the
das_gsa_subscriber
table, and determines whether other Oracle Commerce Platform instances define this item descriptor.If the item descriptor is found, the event server connects to the other event servers identified in
das_gsa_subscriber
.An invalidation event is sent to the target event servers with the pertinent information: event type, item descriptor, and repository ID.
The receiving repositories invalidate caches for that item descriptor.
