Hi, Tim,
Assuming you don't have more than 1000 files, what's your db_files set to and
what's select file#, name from v$tempfile? If you do have more than 1026 files,
select file#, name from v$datafile.
Also show us select * from v$sort_usage if you can run that DELETE again.
XCTEND rlbk=0: your transaction end marker says it's not rolling back; i.e.
it's committing.
