|Default value||For one CPU, there will be one GCS server process.
For 2 - 8 CPUs, there will be 2 GCS server processes.
For more than 8 CPUs, the number of GCS server processes will be equal to the number of CPUs divided by 4. If the result includes a fraction, the fraction is disregarded. For example, if you had 10 CPUs, then 10/4 would mean 2 GCS processes.
|Range of values||
|Real Application Clusters||Multiple instances can have different values.|
GCS_SERVER_PROCESSES specifies the number of server processes in Global Cache Service (GCS) to serve the inter-instance traffic among Real Application Clusters (RAC) instances. GCS server processes are only seen in a RAC environment.
