Hi
I am trying to install oracle application server on redhat advance server 4.
The installer checks the installaiton requirements and following is the output of that check in which its showing faiure while testing the values of msgmnb, msgmni, file-max
How to set correct values of these???

=======================================================================

Checking security kernel parameters
Checking for shmall=2097152; found shmall=2097152. Passed
Checking for msgmnb=65535; found msgmnb=16384. Failed <<<<
Checking for semmns=32000; found semmns=32000. Passed
Checking for semopm=100; found semopm=100. Passed
Checking for msgmni=2878; found msgmni=16. Failed <<<<
Checking for shmmax=4294967295; found shmmax=2147483648. Failed <<<<

Checking for shmmni=4096; found shmmni=4096. Passed
Checking for softnofiles=1024; found softnofiles=16384. 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.

Where to set these parameter against which i am being returned FAILED?

Hello Salman,

Try this to overcome those errors:-
copy paste it as it is on your terminal

echo 65535 > /proc/sys/kernel/msgmnb
echo 2878 > /proc/sys/kernel/msgmni
echo 4294967295 > /proc/sys/kernel/shmmax
echo 206173 > /proc/sys/fs/file-max

To make those changes permenant you can add this line in your /etc/rc.d/rc.local file so the command will be automatically set if your system gets reseted.

Let me know when your problem gets solved

Thank you very much
problem is resolved using your instructions
Regards
