Why when I tried to get the TEMP tablespace offline, the ORA-03217 error did appear?
don't know don't care. I've seen this before -- people try to impose their own notions of how temporary tablespaces work in 8i/9i based on experiences in previous versions. the tablespace appears to be full, so dba's keep adding more datafiles. the ts is not full at all, just the way that the space is allocated has changed.
