问题描述
所以我在Oracle上挣扎了将近2天，于是我放弃了。我相信我已经检查了Google叔叔可用的所有解决方案。
总结我的问题：
- 我已经在Linux RH 7.7上部署了Oracle 19C。 SID = orcl，PDBS = orclpdb和PDB
- 我可以从主机和远程计算机连接到Oracle实例 我可以更改会话集容器= PDB；更改可插入数据库PDB的状态;
但是当我尝试通过以下方式登录到pdb时
-sqlplus（localhost）-oracle / product / 19 / dbhome / bin / sqlplus system / password @ pdb
-Impdp（localhost）
-sqldeveloper（远程）
ERROR:ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

有什么想法为什么不起作用？以及如何使其起作用？
问候 皮奥特
解决方法
这是您在listener.ora中的SID_LIST_LISTENER配置
其中具有“ SID”的可插拔列表意味着侦听器将这些名称当作实例提供。这就是为什么您获得“共享领域等”的原因，因为那些实例不存在（因此被启动）。
典型的listener.ora看起来像
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")
)
)
在这里您可以看到条目仅用于支持主机/端口和外部程序。每个可插拔都将愉快地向侦听器注册，然后将其提供为 services 。
,在我的Vagrant / Virtualbox环境中：
重命名listener.ora（使用默认设置）
[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
重新启动监听器

确保可以使用EZConnect进行连接，然后更改tnsnames.ora以反映您公开的服务。
祝你好运！
,感谢您的重播以及花费的时间。
通过在Listener.ora和tnsnames.ora中的PDB名称中添加FQDN后缀来解决。
也要进行远程连接，我也需要添加此后缀。
