I did a shutdown immediate, but I'm the only one on it.

In recreating the problem, I just figured out why my approach didn't work.
Dropped a digit off the undo tablespace name by mistake.

It all started several hours ago when OEM let me mistakenly create a new 
datafile with a name of '.ora'...
After beating one's head against the wall long enough...

What kind of shutdown did you do?  (Not an abort, I hope!)

Please define "the database would not open up".  Error message?  Error number?  
Anything in alert.log?  Other hints?

I have a problem with one of the files in my undo tablepace.

Given that there are not any transactions to undo, it seemed simplest to just 
drop the file.
But I haven't been able to get the database to let me do that.

So, I created a 2nd undo tablespace with the intention of taking the first off 
line and then dropping it.
But I haven't been able to get the database to let me take it off line.

I found a parameter in my spfile called "undo_tablespace" which was set to the 
old tablespace.
I shut down the database, changed the entry to point to the new tablespace, but 
the database would not open up.

Any ideas on how to clear out the corrupted undo tablespace file?

Thanks in advance!
