As I know that each server process has it's own PGA (shared or
dedicated server). If there are 5 server processes, there will be 5
Actually I think that pga_aggregate_target size is the total size of all PGA which can be allocated by one instance. If it is set to 1G, each PGA get 200M if their loading are similar. If there is only 1 server process, it's PGA can consume up to 1G memory.
Am I correct?
How to know the size of all existing PGA?
