Im trying to install oracle 10g on to OS X Lion, I have previous achieved this on snow leopard with the following http://blog.rayapps.com/2009/09/14/how-to-install-oracle-database-10g-on-mac-os-x-snow-leopard/

The issue im having is that the ulimit settings in the oracle/.bash_profile cannot be modified.

I have the following in the bash_profile:

export DISPLAY=:0.0
export ORACLE_BASE=$HOME
umask 022
# must match `sysctl kern.maxprocperuid`
ulimit -Hu 512
ulimit -Su 512
# must match `sysctl kern.maxfilesperproc`
ulimit -Hn 10240
ulimit -Sn 10240

Upon applying the bash_profile settings . ~/.bash_profile i get the following error:

-bash: ulimit: max user processes: cannot be modify limit: Invalid argument

This then results in $ sqlplus / as sysdba not functioning correctly with a Segmentation fault: 11

The output of $ ulimit -a

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
file size               (blocks, -f) unlimited
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 10240
pipe size            (512 bytes, -p) 1
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 512
virtual memory          (kbytes, -v) unlimited

If any one knows how I can apply these ulimit settings to the oracle user I have created to allow me to install sqlplus and therefore create a db, that would be great.
