    datafile needs media recovery

    Hi,

    I mistakenly added a datafile to tablespace CWMLITE. Since I'm running in archive mode, I took the datafile offline (like Oracle mentions in note: 111316.1).

    ALTER DATABASE DATAFILE OFFLINE;

    Now the datafile is still 1G in size (i took it immediately offline, so no data is in it). When I try to put it online again to resize I get ora-01113: needs mediarecovery (which I think is normal for every datafile you want to put online again).

    How can I get the datafile back online ? I do not have the archives anymore, but would I need them anyway to get it back online ?

    If I can not get it back online, would there be any problem when I startup the database again ?
    The status in v$datafile is RECOVER and in dba_data_files the status is AVAILABLE, shouldn't that be OFFLINE ?

    Thanks,
    Kris

    I think without the Archive Logs your only option is to export the data in the tablespace, drop and recreate the tablespace and re-import

    He has clearly mentioned that his database is in archived log mode.

    krisvdb, you just need to recover your data file with recover command. All archives will be applied automatically to bring it to a consistent state.

    a recovery doesn't work, oracle asks for an archive that I don't have anymore.

    I think I'll just do an export, drop tablespace, import.
    CMWLITE is for OLAP, and we don't use it so I think it's safe.

    Thanks for the replies.
