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@(protected) sybase]$ ulimit -n
1024
[sybase@(protected) 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@(protected) sybase]$ su - sybase
Password:
[sybase@(protected) sybase]$ ulimit -n 2048
[sybase@(protected) sybase]$ ulimit -n
2048
It's not making a lot of sense to me. Any enlightenment appreciated.
Regards, Marshall
