Ulimit error

[Anand Sreenivasan]

I am getting an error when I try to execute the command ulimit -a or ulimit -aH. The error is as follows,
ulimit -aH
ksh: ulimit: bad option(s)
ingxprod:/# ulimit -a
ksh: ulimit: bad option(s)

But, Just ulimit gives back a number, I need to know how much is my no files descriptors is set to so that I can change it. Any help is appreciated. Thanks.

This is non-critical but quite annoying.

If this happens to be an oracle user, there is a component of oracle which is used in setting up the environment oraenv, that doesn't like the world unlimited in the ulimit data and needs to be modified to make this error go away.

I am sorry but I am running this as root. And also, what is that I have to do even if itis for Oracle user to make this go away. Thanks.

Anand,

Which shell are you using? If you are using the bourne shell you will get this error.

Run 'echo $0' and it should show you what shell you are in.

What shell are you using? The ulimit command is part of the shell and may differ depending on the shell being used.

Here is the output
ingxprod:/# echo $0
-ksh

I am using Korn Shell...I went inside SAM to see the values being set and it is set to 1042. I think I can change it there and then process the new kernel which will require a reboot?. Is that correct.I still wants to see this command work. Thanks.

man ksh.

You need to do /usr/bin/ulimit
/usr/bin/ulimit -Ha

what you are oding is shell builtin ulimit

With sh shell, you can do
ulimit -Ha
ulimit -Sa

I got that working by giving it the full path name. Thanks for the help. But To change it, Does it require a reboot ? Or can I edit a file to set this up ?.

No need to reboot. Also you can exceed values set by kernel parameters. You can set it in your .profile file.
OR source it from file
