change ulimit value to unlimited

[Kathryn Paczowski_1]

I have to ulimit questions:

1) How do I change ulimited values to unlimited?

2) Which ulimit values correspond with which kernel parameter?

Thanks

Hi Kathryn,

Somehow I bet you are running ksh and somehow I bet you are running oracle scripts that do a
#!/usr/bin/ksh.

If you are running ksh then you can't. Can you possibly switch to the POSIX shell; then by default ulimit is unlimited.

I can suggest a workaround since almost anything that will run in ksh in execute in the POSIX sh.
1) cd /usr/bin
2) cp ksh ksh.orig
3) cp sh ksh

As for your second question (again this applies to the POSIX shell):

ulimit -d --> maxdsiz
ulimit -s --> maxssiz
ulimit -n --> maxfiles

Hope this helps, Clay
