无法连接到Oracle DB - ORA-01033：正在进行ORACLE初始化或关闭

Question

当我尝试连接oracle DB时，会抛出以下错误：

ORA-01033: ORACLE initialization or shutdown in progress

我在网上搜索并得到了一些解决方案，但没有运气。即使我重新启动数据库并且数据库启动也没有任何错误。以下是日志：

Enter user-name: /as sysdba

重新启动后，我检查了以下内容：

SQL> select status, database_status from v$instance;

STATUS       DATABASE_STATUS
------------ -----------------
OPEN         ACTIVE

SQL> select open_mode from v$database;

OPEN_MODE
--------------------
READ WRITE

任何帮助都将不胜感激。

当可插拔数据库未打开时，可能会发生这种情况。要打开它，请使用

# Start the mypdb pluggable database (if not already running)
SQL> alter pluggable database mypdb open read write;

# Make the read/write state permanent across reboots
SQL> alter pluggable database all save state;
