pmap isn't lying. This entry of your output is related
to the shared memory segment:
80000000 222376 222376 - 222376
read/write/exec/shared [ ism
shmid=0x65 ]
Match the id with the output of the ipcs -ma
Oracle is not all the helpful with could want, however
it has some statistics as session uga memory/session
pga memory and the highwatermarks: session uga memory
max/ session pga memory max from v$sysstat that could
bring a little help.
Regards.
