When Oracle suddenly loses power during operation, when logging in again through PL/SQL, an error is reported
[ORA-01033: ORACLE正在初始化或关闭]
The reason for this may be that the database suddenly stops, and the LOG in the cache area has not been archived in time, so the log file cannot be matched when it is opened next time.
solution:
1. Open the command line interface and enter sqlplus system/sys as sysdba (login as administrator)

2. Enter the command startup mount to load the database, but the prompt statement "ORA-01081: cannot start the running ORACLE - please close it first" is reported. So use the command shutdown immediate to unload the database, and then load it. This process takes a little time, so be patient.
SQL> startup mount
ORA-01081: 无法启动已在运行的 ORACLE - 请先将其关闭
SQL> shutdown immediate
ORA-01109: 数据库未打开
已经卸载数据库。
ORACLE 例程已经关闭。
SQL> startup mount
ORACLE 例程已经启动。

3. Enter the alter database open; command. If there is an error message "ORA-01589: RESETLOGS or NORESETLOGS option must be used to open the database", then use the command alter database open resetlogs; [be
sure to enter a semicolon, otherwise the relevant content cannot be output correctly. 】
SQL> alter database open;
alter database open

4. Enter the command recover database using backup controlfile; [need to enter a semicolon]
