  Oracle Database Tips by Donald Burleson

Oracle10g Grid Computing with RAC
Chapter 7 - Cache Fusion and Inter Instance Coordination

 Global Resource Directory

More details about the above resources are covered in later sections.

The GRD is similar to the previous version of the lock directory from a functional perspective, but it has been expanded with more components. It contains an accurate inventory of resource status and location.

RAC Processes

The following additional processes are spawned to support multi-instance coordination:

LMON - The global enqueue service monitor (LMON) monitors the entire cluster to manage global enqueues and resources. LMON manages the instance, the process expirations, and the associated recovery for the global cache service.

LMD - The global enqueue service daemon (LMD) is a lock agent process that coordinates enqueue manager service requests. The requests are for global cache service enqueues that control access to global enqueues and resources. The LMD process also handles deadlock detection and remote enqueue requests.

The above text is an excerpt from:
