Answer / guneetinder singh
When an oracle server starts up it will allocate two memory
areas SGA(System global area) and PGA(Program Global Area).
SGA is allocated to the user when any new oracle instance
starts up at the server for sharing different data between
difference users.
PGA is allocated to the server when oracle server starts up.
in this only server processes can work.

Answer / bhaskar
Hi,
It is the part of memory used by a singe process or thread.
Each oracle background process have PGA area.and is not
sharable.it get allocated when the process starts and gets
deallocated on completion of the process by oracle server.
It contains short area,session specific information,user
previliges,cursor state etc.It is writable only by the
server process.
Thanks-Bhaskar Gouda
