RH ES2.1, 2.4.21-15.ELsmp I am trying to give our DBA the ability to test his Sybase installation with various parm changes, one of which is "ulimit -n". I have added: Sybase soft nofile 3072 Sybase hard nofile 4096 to the /etc/security/limits.conf file and that sort of works. I say sort of because if I log in as Sybase and execute ulimit -n 2048 I get: [sybase@fsh1166db02 sybase]$ ulimit -n 1024 [sybase@fsh1166db02 sybase]$ ulimit -n 2048 -bash: ulimit: open files: cannot modify limit: Operation not permitted Then if I "su - sybase" and do it again, it works: [sybase@fsh1166db02 sybase]$ su - sybase Password: [sybase@fsh1166db02 sybase]$ ulimit -n 2048 [sybase@fsh1166db02 sybase]$ ulimit -n 2048 It's not making a lot of sense to me. Any enlightenment appreciated. Regards, Marshall -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
