Kernel Parameters

jpcast_real — Thu, 14 Apr 2005 09:57:10 GMT

Hello Gurus,

I having problems of any kernel parameter. Is there any tool to monitor the current state of kernel parameters . Glance does not say the value of all of them . Apart of it , do you have any rule to adjust the kernel parameters of oracle?

Regards

To check kernel parameters:

sam -> kernel configuration -> configurable parameters.

I mean the current state , not the maximum value of a kernel parametere

Hi Javier,

The kmtune command will show you all current kernel values.

I'm not sure about the rules for Oracle. Sorry.

Hi,
You may want to have a look at the contents of /stand/system file.

Have a look at "http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:454420165038" and "forums1.itrc.hp.com/service/ forums/questionanswer.do?threadId=847351".

These should give you some help.

The set kernel parameters can be checked with kmtune/sysdef/sam

The current usage of them (not all) can be monitored as follows

glance -t
sar -v 5 5

If you are on 11.23, you almost can monitor the usage of them all. (Check kc commands.)

Hi

You can use kmtune command which will help you, some configured values can be seen on /stand/system file.
Generally oracle has a set of standard kernel parameter which they need to be set(some/most of them) would not follow the rule for which you can hard code it.
