2.145 GCS_SERVER_PROCESSES
GCS_SERVER_PROCESSES
specifies the number of background GCS server processes (LMSn and LMnn) to serve the inter-instance traffic among Oracle RAC instances.
If there is high Cache Fusion congestion on the system, the number of GCS server processes could be increased to reduce Cluster wait time. Additionally, the number of GCS server processes could be increased to reduce the application brownout time associated with Cluster reconfiguration and Dynamic Re-mastering (DRM).
