My point is that autoexend gives you the same problem. You see in the file system that you have 1gb free and so you can use it. your dba can see in oracle that the datafile can grow by another 500mb before it hits its size limit so the sysadmin and the dba both assume that that space is free for their use. Oracle can tell you the size of the files so I don't really see the problem.
