Sys mem is very High

Dears,

The RAM of Prod1 server about 13GB and recently we installed Oracle application that server,,, anyway I noticed that sys mem consumed a lot of RAM which is about 50% of total RAM, see the following readings from glance

***********************************
Total VM : 10.4gb Sys Mem : 6.2gb User Mem: 6.5gb Phys Mem : 13.3gb
Active VM: 8.2gb Buf Cache: 1mb Free Mem: 494mb FileCache: 96mb
***********************************

note that ORACLE require to change some of kernel parameter

can you help me to find a way to decrease sys mem utilization?

hi,

for the oracle is normal the memmory usage, yes you can optimize ( tune ) the amount of memmory with the oracle configuration file.

and also its depend on your kernel parameters.

check the recommended values in installation manual from oracle.

decrease system kernel parameter dbc_max_pct in 10 and it will consize the system memory usage.

Re: Sys mem is very High

I couldn't find dbc_max_pct to modify its value...

I think becuase I am using HP-UX v3 the dbc_max_pct no longer tunable ...

do you have other suggestion
??

Right. And it is only 1 Mb. And the filecache is only 96 Mb. So you don't have to decrease either.
