We have CEntos 5.5 on DELL server. Due to more and more databases run on same server sometime processes number read max and cause 'resource temporary unavailable".

I plan to change /etc/security/limits.conf value:

oracle soft nproc 2047 ==> 4096

Do i need reboot to make it effect?

How to test change is effect?
