ORA-01123: "cannot start online backup; media recovery not enabled"
 *Cause: An attempt to start backup of an on-line tablespace failed because
          media recovery is not enabled.
 *Action: Enable media recovery and retry this operation.

You are in NOARCHIVELOG mode, you can't make a media recovery.
