you don't need to change the system headers. If your requirement is process
based i.e. you want lots of descriptor in any particular process then use
syscall setrlimit otherwise for any user set it in
/etc/security/limits.conf.

but there is a limit on that like default value is NR_OPEN
If above does not satisfies your then increament the NR_OPEN value.
