| Zusammenfassung: | A system serialization capability is provided to facilitate processing in those environments that allow multiple processors to update the same resources. The system serialization capability is used to facilitate processing in a multi-processing environment in which guests and hosts use locks to provide serialization. The system serialization capability includes a diagnose instruction which is issued after the host acquires a lock, eliminating the need for the guest to acquire the lock. |
