RE: How to drop a data file from a tablespace quickly
ashoke, that's going to corrupt his database.. at some point.

RE: How to drop a data file from a tablespace quickly
We tried drop offline and it did not work. It appears that once the datafile is accessed in any way, you can not get rid of it by dropping it. If there is viable data, export it. Then drop the tablespace, rm the datafile(s) (UNIX), re-create the tablespace, and then import the export (assuming you did an export).

Re: How to drop a data file from a tablespace quickly
Uh-oh... another urban legend? ALTER DATABASE DATAFILE '...' OFFLINE DROP is not a command to drop a datafile from the tablespace. The file is be in the v$datafile and controlfile FOREVER even you issue the offline drop command. That command is only for you to put that datafile in the RECOVERY mode and tell Oracle that you will recovery that file later. You will HAVE TO DROP THAT TABLESPACE if you cannot recover that file.
