We have CENTOS 4.7 on DELL server.  our /etc/security/limits.conf already setup as:

*               soft    nproc          2047
*               hard    nproc          16384
*               soft    nofile         4096
*               hard    nofile         65536
oracle          soft    nproc          2047
oracle          hard    nproc          16384
oracle          soft    nofile         8192
oracle          hard    nofile         131072

I login as "oracle" again (bash) and tried to run:

$ ulimit -n 131072
-bash: ulimit: open files: cannot modify limit: Operation not permitted

Anyone know why?
