What is the best way to drop datafile from tablespace with multiple datafiles if the datafile is no longer needed ?

Thanks.

In 9i, you can't drop a datafile in a tablespace, you have to drop the whole tablespace.
In 10g, you can use "alter tablespace ... drop datafile ...", if the file is empty.

In 9i, what is the purpose of alter database datafile ... offline drop ?

Thanks.

You put the datafile offline and you say to Oracle that you want to drop it but this has no effect in Oracle.
It is bad named; in 10g, this clause has been renamed to a better "offline FOR drop".
