I haven't logged in to the Oracle server for a long time. I forgot my password.

Sql > conn sys/sys as sysdba

Sql > alter user system identified by *

The result is ORA-01219: the database is not open: only queries in fixed tables / views are allowed-did you encounter an error if you want to change the password?!

Sql > startup

ORA-01081: unable to start ORACLE that is already running-Please close first

Then sql > shutdown immediate

Sql > startup;-- error persists

In the execution: select open_mode from v$database

Display:

OPEN_MODE

-

MOUNTED

-- return mounted to indicate that the database has been mount

-- return read write or read only to indicate that it is open

-- No mount is not returned

After countless web searches, it is finally solved as follows:

SQL > alter database open

Alter database open

*

An error occurred on line 1:

ORA-01157: unable to identify / lock data file 5-see DBWR trace file

SQL > shutdown immediate
