If you have a RMAN backup (inluding the archived logs), repeat the recover statement from RMAN.

If you don't have archived logs you can't recover in the current database.
All you can do is create a new database with your backup, export the content of the files and reimport it in the original database.
Of course, you lose all modifications since the backup.

If your file 24 is empty then move all objects from the current tablespace into another one and then drop the current tablespace.

ora-00275: media recovery has already been started
 *Cause: An attempt was made to start a second media recovery operation
         in the same session.
 *Action: Complete or cancel the first media recovery session or
          start another session to perform media recovery.

First exit from SQL*Plus and retry.

After it proposes you an archived log either:
1/ accept it with: alter database recover continue;
2/ change the name with: alter database recover logfile '<name>';
3/ stop with: alter database recover cancel;

You can also say it continues automatically without asking you for each log file, answer:
alter database recover continue default;

Or start with: alter database recover automatic datafile 24;

Michel

I've done nothing but read what is in SQL Reference section "ALTER DATABASE RECOVER".
