!! Please do not post Off Topic to this List !!

Top shows the SGA size with each process, using pmap you can actually see the break down.

With a 200Mb SGA (or slightly less actually) you will see 200Mb tied to each process, plus the process memory.

Unfortunately I have not seen a tool as useful as top which has distinguished this.

Hey gang. New job, new problems. I have just been handed a 8.1.7.0.0 database on solaris 5.8 with a little problem. Everything time a client connects, regardless of type, the OS dedicates over 200+ Megs of RAM (as shown by Top) to the user process. Naturally, this is running the box out of memory. The init.ora has the following parameters:
db_block_size = 8192

   db_block_buffers = 9652
   large_.pool_size = 2000000
sort_area_size=65342
sort_area_retained_size=65342

There is nothing from any logs or trace files that helps. Plus, I am new to UNIX.
Any help you could offer would be greatly appreciated.
