Why using swap space instead of real memory? #2
Output from top:
Box is running 3 instances of oracle.
last pid: 25158; load averages: 4.72, 5.64, 6.30 12:28:49
477 processes: 467 sleeping, 5 zombie, 5 on cpu
CPU states: 80.0% idle, 8.5% user, 3.9% kernel, 7.6% iowait, 0.0% swap
Memory: 14G real, 7447M free, 6834M swap in use, 5846M swap free
Why would swap being used instead of real memory? Could that have been
instructed to used swap ? How to know.
Here is buffer cache, is it too large? how about Shared memory?
sysdef info
292241408 maximum memory allowed in buffer cache (bufhwm)
4294967295 max shared memory segment size (SHMMAX)
SunOS cltsunp01 5.8 Generic_117350-25 sun4u sparc
SUNW,Ultra-Enterprise-10000
14 GB Mem, 28 X 400 MHz CPUs
And there are 3 instances of Oracle 9.2.06. Size of the largest DB is
200 GB
Thanks.
