Well, first, try a ‘recover datafile ‘/path/to/offline/datafile’
It’s possible, depending on how long the file has been offline, that you’ll recover it from just the on-line redo. (Perhaps not likely, but it’s worth a try.)
If recovery is not possible, the next best option is to drop the tablespace containing the file. If there’s data in that tablespace that you want to retain, you could create a new tablespace, and then move any tables out of the problem tablespace into a new tablespace, and rebuild indexes into the new tablespace, then drop the problem tablespace.
Those are the most simple and straightforward solutions.
Will either one work for you?
