Oracle Database File Corruption, error: ORA-01033: Oracle initialization or shutdown in progress

Oracle Database File Corruption has been solved. The problem is "error: ORA-01033: Oracle initialization or shutdown in progress", and later from the Internet to find some information, and finally add their own practice finally solved, but there is a problem, it seems that the database files are useless.

Solution
In a DOS environment
Sqlplus/nolog
SQL> connect sys/sys as sysdba
SQL> shutdown normal
SQL> startup Mount
SQL> alter database open;

Row 3 has an error:
ORA-01157: unable to identify/lock data file 6-see dbwr trace file
ORA-01110: data file 6: 'd:/Oracle/oradata/oragwh/indx01.dbf''

If this problem occurs, continue to enter
SQL> conn sys/sys as sysdba;
Connected.
SQL> alter database datafile 6 offline drop;

Until Scott logs in.
SQL> conn Scott/Tiger

Then enter
SQL> shutdown normal
SQL> startup
