Hi,
>
Its in not recovery mode, or you do not have any backup?
Then you have to drop that file from SQL as
SQL> alter database datafile 'Location' offline drop;
I tried what you have mentioned..
SQL> alter database datafile '/oracle/oradata11g/cboedbCBOEDEV_T24DISTINDEX1.dbf' offline drop;*
Database altered.*
SQL> alter database open;*
alter database open*
+*
ERROR at line 1:*
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open*
SQL> alter database open NORESETLOGS;*
alter database open NORESETLOGS*
