After offline drop datafile, v$datafile.status='RECOVER'

Question

OS version:
[oracle@base ~]$ uname -a
Linux base.no.sohu.com 2.6.9-55.ELsmp #1 SMP Fri Apr 20 17:03:35 EDT 2007 i686 i686 i386 GNU/Linux
DB version:
SQL> select version from v$instance;
VERSION
9.2.0.1.0Here is my steps,
SQL>alter database datafile '/usr/oradata/bill/soq05.dbf' offline;
Database altered.
SQL>alter database datafile '/usr/oradata/bill/soq05.dbf' offline drop;
Database altered.Cause there is nothing errors generated, I thought the commands executed sucessfully. But it's not.
SQL> SELECT NAME,STATUS FROM v$datafile WHERE NAME='/usr/oradata/bill/soq05.dbf';
NAME                                     STATUS
/usr/oradata/bill/soq05.dbf              RECOVER
SQL> SELECT FILE#, STATUS, ERROR, RECOVER, TABLESPACE_NAME, NAME 
  2  FROM   V$DATAFILE_HEADER 
  3  WHERE  RECOVER = 'YES'  OR     (RECOVER IS NULL AND ERROR IS NOT NULL);
     FILE# STATUS  ERROR                RECOVER              TABLESPACE_NAME                NAME
        18 OFFLINE                      YES                  SOQ                            /usr/oradata/bill/soq05.dbf
[oracle@base ~]$ ll /usr/oradata/bill/soq05.dbf
-rw-r-----  1 oracle oinstall 1073750016 Aug 28 17:39 /usr/oradata/bill/soq05.dbfThe datafile haven't been droped successfully and its status changed to 'RECOVER'. Also, I can't online it now.
What should I do to make this datafile droped or at least make it online/offline? What I am worry is the database will be failed to restart because of this 'RECOVER' datafile.
Thanks very much!

Hey Werner,
Thanks very much for your help.
The reason I tried to drop the datafile is after I add the datafile to tablespace, I found the datafile failed to be created on the standby side because the parameter "db_file_name_convert"'s value were incorrect. When I created the datafile on primary side, the value of "db_file_name_convert" was,
SQL> select name,value from v$parameter where name='db_file_name_convert';
NAME                           VALUE
db_file_name_convert           /home/oracle/bill/oradata/bill, /U02/bill/oradata/billIt should be VALUE='/usr/oradata/bill','/U02/bill/oradata/bill'. For now the datafile's status on standby side is,
SQL> SELECT name,status FROM V$DATAFILE where file#=18;
NAME                                               STATUS
/U02/bill/product/9.2.0.1/dbs/UNNAMED00018         RECOVERIf the datafile on primary side could been recovered successfully, is there a way to make the datafile on standby side also correct?
Thanks
