Increase number of processes allowed for user oracle:

man ulimit

Hi Michel
I did it in /etc/profile

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

still the same error

I don't know, this is a question you should post in a Linux forum not an Oracle one.

Of course users can't set their own limits.

root sets the limits that the users are allowed to have.

So it is useless to put it in /etc/profile, root must change the limits with ulimit.

Pick one (or even both):
a) sit and cry over your miserable destiny
b) find a person who can set limits for you (such as a system administrator; Thomas says root)

Is this not clear?
Connect as root and change the limit for oracle account.

To go further, please find a more appropriate forum.
The topic is locked.
If I'm wrong, please, PM me (or report this message to a moderator, explain why you think it should be unlocked and it might be done).
