If I'm not mistaken, this figure includes the size of the shared memory
segment from the SGA. Take the output of the "oracle" line of "ipcs -a"
(hopefully you'll only have one!) and subtract it from the process size to
get a better idea of the non-shared memory size of the process.

SGA is shared memory so it will show up looking as though the
individual connections are as large as the SGA (or larger, to include
the PGA). In reality they are sharing a large chunk of the memory

When looking at the processes(dedicated connections) of an 816 database on a

the SGA.

Is this normal? Thanks
