Unable to recover datafile - urgent

There is one datafile which shows status of "RECOVER". This datafile was created in the wrong tablespace and immediately offlined. For some reason a batch job is trying to read from this datafile, and it comes up with ORA-376 and ORA-1110. I am not able to recover this datafile because it needs an old archive log and that archive log does not exist on the system.

How can I find out if this datafile has any objects in it? (I am pretty sure it does not). And if it does not I would like to remove this datafile.

Is exporting tablespace/dropping tablespace and reimporting my only option?

Thanks,

Manjula
