Oracle documentation 10.2, Linux 4

Depending on the oracle user's default shell, make the following changes to the default shell start-up file:

For the Bourne, Bash, or Korn shell, add the following lines to the /etc/profile file (or the file on SUSE systems)/etc/profile.local:

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

Result

[oracle@localhost ~]$ ulimit -p 16384
-bash: ulimit: pipe size: cannot modify limit: Invalid argument
