It depends
On most single instance installations I tend to use the projects, but on rac 
environments I put it in /etc/system. Reason for this is that the project group 
used depends if the instance is started by the cluster or by you.

Subject: solaris 10 kernel parameters


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 ** 
SHMMAX 4294967295 
SHMMIN 1 * 
SHMMNI 100*** 
SHMSEG 10 * 
NOEXEC_USER_STACK 1 
* obsolete in Solaris 9 and 10 
** obsolete in Solaris 10 
*** default value in Solaris 10 is already larger 
Note: 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): 
project.max-sem-ids 100 (semmni) 
process.max-sem-nsems 256 (semmsl) 
project.max-shm-memory 4294967295 (shmmax) 
project.max-shm-ids 100 (shmmni)
