Oracle 10g Installation/Applying Patches Tips

Posted on 28-Sep-2005 By Admin No Comments on Oracle 10g Installation/Applying Patches Tips

*******Oracle 10g Installation ******* On 27-Sep-2005******

(1) *** Warning During Oracle 10.1.0.2 installation ****

Checking security kernel parameters

Checking for noexec_user_stack=1; found Not found. Failed <<<<
Checking for BIT_SIZE=64; found BIT_SIZE=64. Passed

Check complete. The overall result of this check is: Failed <<<< Problem: The security parameters in the kernel do not meet the minimum requirements (see above).
Recommendation: Perform operating system specific instructions to update the kernel parameters, namely BIT_SIZE and noexec_user_stack.

(2) *** Warning ****

Value of semmni is less than 100,

Value of Semmns is less than 1024.

Though above error came, oracle installed successfully.

After installing a non-RAC (Real Application Clusters) 10g database, you notice an ocssd.bin process running.

stsun7% ps -ef | grep ocssd.bin

oracle 11139 11056 0 14:02:14 pts/52 0:00 grep ocssd.bin

oracle 1824 1 0 Mar 12 ? 0:01 /oracle/64bit/10.1.0/bin/ocssd.bin

In a non-RAC environment, the ocssd.bin process is used for communication between a database instance and the ASM (Automatic Storage Management) instance. Even if you are not using ASM this process will be run out of the inittab:

stsun7% more /etc/inittab | grep cssd

h1:3:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1

This process does not consume many resources and can be ignored if you are not running RAC or ASM. If you decide that you want to use ASM in the future, it will be necessary for this process to be running.

So we commented that process from /etc/inittab file and stop it as followiing:

(*) Commented in inittab.

#h1:3:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1 (*) stoppping running cssd process.

# /etc/init.d/init.cssd stop

Shutting down CRS daemon.

Shutting down EVM daemon.

Shutting down CSS daemon.

Shutdown request successfully issued.
