Global resource serialization processes requests for local resources and requests for global resources differently. When a task running on a system in the ring requests a local resource, that system handles the request on its own. Global resource serialization does not place a local resource request in the RSA-message.

When a task running on a system in the ring requests a global resource, however, the processing is very different because each system in the ring must keep track of all requests for global resources. How the ring processes a request for a global resource depends on whether or not your installation uses ring acceleration.
