cannot fork process on IBM - AIX
Hi,

Currently, I'm getting the foll error on an IBM AIX
/etc/profile[36]: 0403-030 The fork function failed. Too many processes already exist.

How can i check the current no. of processes which can run simultaneously on an IBM AIX machine for oracle user and how can i change ?

Thanks
Vin

Please check the contents of your .profile.

The max number of processes can be started by a user is set by maxuproc parameter of sys0 device(kernel). This can be altered from 128 (default).

using chdev -l sys0 -a maxuproc=512 or so

But as oracle user doesn't fork so many processes it has something to do with your profile entries.

You can check by renaming your current profile and including a single command like 'ls -l' or 'whoami' only inside your profile and logging in as the user.

Let me know how many times the ls -l runs when you do so.

TIP "If your profile contains a line ./.profile it can end up creating infinite number of recursive processes :-)"

Thanks

Ranjith
