The following are the additional processes spawned for supporting the multi-instance coordination:
LMON - The Global Enqueue Service Monitor (LMON) monitors the entire cluster to manage the global enqueues and the resources. LMON manages instance and process failures and the associated recovery for the Global Cache Service (GCS) and Global Enqueue Service (GES). In particular, LMON handles the part of recovery associated with global resources. LMON-provided services are also known as cluster group services (CGS)
LMDx - The Global Enqueue Service Daemon (LMD) is the lock agent process that manages enqueue manager service requests for Global Cache Service enqueues to control access to global enqueues and resources. The LMD process also handles deadlock detection and remote enqueue requests. Remote resource requests are the requests originating from another instance.
