Home -> Community -> Mailing Lists -> Oracle-L -> Re: What should sys admins know about Oracle?
All I know is, the more my sysadmin (and heck, my developers while I'm at
it) know about Oracle, the less likely they are to question me when I say I
want LOTS of disks and want them to up the semaphores and no, you cannot
have the entire database on one disk.
Rachel -- who is very happy with her sysadmins at the moment :)
