Thanks Jared

<<You should probably investigate why it continues to grow so large>>

Whats the best way to go about identifying any large transactions?

The data file(s) for your undo tablespace is likely set as autoextend with an unlimited size.

Run the attached script to check it.

If so, you can use this to put a limit on it:

alter database datafile '<your file name>' autoextend on next 200m maxsize 2000m;

Adjust the numbers for your system.

You should probably investigate why it continues to grow so large.

I haven't yet converted our production databases to UNDO, having only recently migrated to 9i, so I don't have any useful advice past this.

There are others that will be able to offer more for this. ( Dan Fink, where are you? This might even get Kirti to take a break from his book for a few minutes )
