solaris 10 kernel parameters
Date: Wed, 7 Oct 2009 20:51:30 -0500
What do most people do:
Keep using /etc/system in Solaris 10 or the Resouce Control Facility? Or do people ignore the parameters and not set any in /etc/system or the Resouce Control?
I have a unix admin saying nothing needs to be set because they read that /etc/system is not used in Solaris 10 anymore. Below is from a doc on metalink. At the minimun the new kernel parameters for Solaris 10 need to be set. Is this correct?
Is NOEXEC_USER_STACK 1 set in /etc/system or the Resouce Control?
SEMMNI 100 *** SEMMNS 1024 ** SEMMSL 256 ***
SEMVMX 32767 **
SHMMIN 1 *
SHMSEG 10 *
* obsolete in Solaris 9 and 10 ** obsolete in Solaris 10 *** default value in Solaris 10 is already largerNote: for Solaris 10 SHMMAX which is now set through the Resource Control Facility not /etc/system. Refer to the 10gR2 for Solaris SPARC Installation guide for steps to do this, as well as, the Release Notes which has corrections:
10.2 Install Guides and Release Notes
Here are the new names of the kernel parameters for Solaris 10 (Solaris 9 equivalents are in parentheses):
