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. regards, Freek D'Hooge Uptime Oracle Database Administrator e-mail: freek.dhooge@xxxxxxxxx tel. +32 (0)3 451 23 82 http://www.uptime.be disclaimer From: oracle-l-bounce@xxxxxxxxxxxxx [oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Joe Smith [joe_dba@xxxxxxxxxxx] Sent: 08 October 2009 03:51 To: oracle-l@xxxxxxxxxxxxx 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) Hotmail: Trusted email with Microsoft’s powerful SPAM protection.
