Amazingly enough, I attended the Oracle class 'Managing Oracle on Linux' in May and they went over this is some detail. Even though I had installed Oracle on Linux several times (SuSE and Red Hat flavors), I attended the class in hopes of picking up some tips. I was not disappointed. Setting the kernel parms on the fly was one of them.

Nice.  I haven't even looked at setting these parms in linux
in a couple years, didn't know this was available.

So, how do you set SHMMAX, etc on linux using sysctl?

The man pages weren't much help.

just use sysctl -p
after writing yr preeferred settings into /etc/sysctl.conf

for advanced linux guys: they can be set directly - but the previous way is more convinient.

in case you don't set them yr installation might hnag when creating the database instance. in this case just install the database later. means start dbassiost fter setting the kernel params. doesn't need a complete re-install.

Hi Jared,



I ventured into my first red hat install not to long ago, but these parameters do do need a kernel rebuild (afaik)

Unless you've run into errors requiring adjustment of these parameters, don't bother with them.


I've run 4 databases on a 2Gig RAM RH 7.1 box without ever touching these.

Modifying them requires rebuilding the kernel, which can be quite a hassle.

It also invalidates Oracle support on linux.
