Dear managers,
I noticed that most oracle-processes are using excessive resident memory.
Below some processes: ( tru64 5.1A PK2 / oracle 8.1.7.3)
# ps auxw | egrep 'RSS|oracle'
USER PID %CPU %MEM VSZ RSS TTY S STARTED TIME COMMAND
oracle 389837 0.0 17.1 1.09G 349M ?? S Aug 03 1:56.19 ora_snpv
_pvfbqp
oracle 389828 0.0 23.0 1.08G 469M ?? S Aug 03 1:33.94 ora_snpt
_pvfbqp
oracle 389824 0.0 10.1 1.08G 207M ?? S Aug 03 1:20.46 ora_snpp
In total there are 46 oracle processes using on average 300MB resident
memory.
The total resident memory is about 13GB on a system with 2.0GB physical
memory !
The system is performing normally.
Does anyone had similar experiences ?? and maybe a explanation ?
# vmstat -P
