memory hungry box

[Scunningham99]

hi we have a enterprise 2 box which is using an large amount of memory with nothing running.

SunOS lsi 5.6 Generic_105181-26 sun4u sparc SUNW,Ultra-2

Here is the output from a top command after we shut oracle database down. no processes running other than what is owned by root:-

last pid: 24844; load averages: 0.04, 0.07, 0.08 11:55:28
88 processes: 86 sleeping, 1 zombie, 1 on cpu
CPU states: 98.2% idle, 0.0% user, 1.8% kernel, 0.0% iowait, 0.0% swap
Memory: 2048M real, 783M free, 26M swap in use, 487M swap free

ANY IDEAS???

THAKS IN ADVANCE

The filesystem buffer cache can use all your spare memory, it's not a problem, it will reduce its usage should your applications need the memory. Unfortunately you can't see that in top on Solaris. Annihilannic.

thanks for reply

Senario (is this normal)

when i cleanly start up the box we have approx. 1.9 gig of memeory(physical) free. Then whe i startup database and cleanly shut it down (so there are no more database processes running) There is only 650meg free, with the same amount processes running as before.

NOTE: is am using the memory didplay from the top command. Please can anyone explain why this is happening!

THANKS IN ADVANCE!!

Yes, that's normal. It gradually allocates memory to the buffer cache as required, and unless there's a good reason to free it, it hangs on to it.

Don't worry, it's not a problem! Annihilannic.
