Global Enqueue Service
The Oracle RAC service that coordinates cluster-wide locks and enqueue resources that protect shared database structures.
Technical Context
GES complements block-oriented cache coordination by managing global resource locking. Diagnosing cluster contention requires separating global enqueue waits from global cache block-transfer waits because their root causes and remediation differ.
