所以我和甲骨文斗争了将近两天，我放弃了。我相信我检查了谷歌叔叔提供的所有解决方案。

总结一下我的问题：

  1. I已经在LinuxRH7.7上部署了Oracle19C。SID = orcl，PDBS = orclpdb和PDB
  2. I可以从主机和远程机器
  3. 连接到Oracle实例，可以更改会话集容器= PDB；更改可插拔数据库PDB打开；

但是当我尝试登录pdb时

-Sqlplus(本地主机)-甲骨文/产品/19/dbhome/bin/sqlplus系统/密码@pdb

-Impdp (本地主机)

-Sqldeveloper (远程)

​

我收到一个错误：

这是SID_LIST_LISTENER在listener.ora中的配置

将可插入的列表作为"SID“，意味着监听器提供这些名称，就像它们是实例一样。这就是您获得“共享领域等”的原因，因为这些实例不存在(因此启动)。

一个典型的listener.ora可能看起来像

代码语言：javascript
复制
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1519))
    )
  )

SID_LIST_LISTENER19 =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oracle\product\19)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\oracle\product\19\bin\oraclr19.dll")
    )
  )

在您可以看到条目的地方，只需要支持主机/端口和外部程序。每个可插拔程序都会很高兴地向监听器注册，然后监听器会将可插入性作为服务提供出去。

在我的Vagrant/Virtualbox环境中：

重命名listener.ora (使用默认设置)

复制
[oracle@localhost ~]$ mv /u01/app/oracle/product/19.0.0/grid/network/admin/listener.ora /u01/app/oracle/product/19.0.0/grid/network/admin/listener.ora.1

确保可以使用EZConnect进行连接，然后修改tnsnames.ora以反映公开的服务。

祝你好运！

谢谢你的重播和你花在它上的时间。

解决了在Listener.ora和tnsnames.ora中将FQDN后缀添加到PDB名称中的问题。

此外，为了远程连接，我也需要添加这个后缀。
