ORA-01033: ORACLE initialization or shutdown in process, shutdowninprogress

Oracle encountered a problem: after entering the user name and password in PL/SQL, a title error occurred. I have not backed up all the database databases in a project, and there is still a lot of data, this won't let me reload the database. Think of this stream I sweated.

I checked my article on the Internet and found a solution. It really broke my sweat. This problem is mostly caused by the loss of database files.

After Oracle is started, the user logs on to load the original configuration information in the solution. During the loading process, an error is reported because the location specified by the original file is not found.

The solution I found on the Internet is as follows:

Enter dos:

Log On As a dba user. The specific command is
Sqlplus/NOLOG
SQL> connect sys/change_on_install as sysdba
Tip: Successful

SQL> shutdown normal
Tip: the database is closed.
Database uninstalled
ORACLE routine disabled

SQL> startup mount
Tip: The ORACLE routine has been started.

Redo Buffers 532480 bytes
Database loaded

SQL> alter database open;
Tip:
Row 3 has an error:
ORA-01157: unable to identify/lock data file 19-see DBWR trace file
ORA-01110: Data File 19: ''' C: \ oracle \ oradata \ oradb \ FYGL. ORA''
The file part of this prompt varies depending on different situations.

Continue Input
SQL> alter database datafile 19 offline drop;
Tip: the database has been changed.

Loop through the last two steps until alter database open; then no error is prompted, "the database has been changed ".
Then enter
SQL> shutdown normal
Tip: the database is closed.
Database uninstalled
ORACLE routine disabled

SQL> startup
Tip: The ORACLE routine has been started.

Then there should be no problem in login!
