OK I finally got back to this and no matter what I put in the limits.conf, I still must su to the same user that I log in as in order to change the ulimit parms. It's really not making any sense. [sybase@fsh1166db01 sybase]$ whoami sybase [sybase@fsh1166db01 sybase]$ ulimit -n 1024 [sybase@fsh1166db01 sybase]$ ulimit -n 4090 -bash: ulimit: open files: cannot modify limit: Operation not permitted [sybase@fsh1166db01 sybase]$ su - sybase Password: [sybase@fsh1166db01 sybase]$ ulimit -n 1024 [sybase@fsh1166db01 sybase]$ ulimit -n 4090 [sybase@fsh1166db01 sybase]$ ulimit -n 4090 [sybase@fsh1166db01 sybase]$ Regards, Marshall -----Original Message----- From: Joe Hood [mailto:joe.hood@xxxxxxxxx] Sent: Monday, May 09, 2005 12:15 PM To: General Red Hat Linux discussion list Subject: Re: Ulimit command only works after su @dba hard nofile 65535 @dba hard nproc 16384 @oaa hard nofile 65535 @oaa hard nproc 16384 is how Oracle recommends (with groups instead of users), I'm sure Sybase is similar. Also, you have "Sybase" as a user with a capital first letter.
