Problem in setting kernel parameters SUSE 7.0 (2.2.16 kernel )

S Bhat — Mon, 31 Jul 2006 09:13:47 GMT

I am facing problem with my Oracle perfomance running od SuSE 7.0 ( 2.2.16 kernel ).
The following parameters are not set.

SHMSEG, SHMMIN , SHMMNI, SEMMNI, SEMMSL, SEMMNS, SEMOPM, SEMVMX .

I have added these parameters to /etc/sysctl.conf file and ran following commands. It is throwing following errors.

#sysctl -p /etc/sysctl.conf
error: 'kernel.shmseg' is an unknown key
error: 'kernel.shmmin' is an unknown key
error: 'kernel.semmni' is an unknown key
.
.
.

Could any one tell me hwo to set these kernel parameters in 2.2 kernel?

Thanks in advance.

Shashi,

You should read installation manuals for your Oracle version (7.x ?) under 2.2 kernel.
As far as I remember, in 2.2 kernels you should recompile kernel in order to change these params.

http://www.oracle.com/technology/tech/linux/index.html and http://www.puschitz.com/ should help you.

Rgds,
Vitaly

a 2.2 kernel? you cannot set those values using sysctl. you need to edit the source code and recompile.
