database - 无法连接到 Oracle 数据库 - ORA-01033 : ORACLE initialization or shutdown in progress

Question

当我尝试连接 oracle 数据库时，它抛出以下错误:

ORA-01033: ORACLE initialization or shutdown in progress

我在网上搜索了一些解决方案，但没有成功。即使我重新启动了数据库，数据库也没有任何错误地启动了。以下是日志:

Enter user-name: /as sysdba

重启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

如有任何帮助，我们将不胜感激。

当可插入数据库未打开时，可能会发生这种情况。打开它使用

# 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;
