重命名listener.ora（使用默认设置）

Question

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

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）

我收到一个错误：

ERROR:ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
Additional information: 4376
Additional information: -1774770425
Process ID: 0
Session ID: 0 Serial number: 0

我的环境如下：

show pdbs;
    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
     2 PDB$SEED                       READ ONLY  NO        
     3 ORCLPDB                        MOUNTED              
     4 PDB                            READ WRITE NO     

$ echo $ORACLE_HOME
/oracle/product/19/dbhome
$ echo $ORACLE_SID

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

Answer 1

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！

Answer 3

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。

无法连接到PDB，Oracle 19C Linux RH7.7 ORA-01034，ORA-27101

3 个答案:

重命名listener.ora（使用默认设置）

重新启动监听器

哦，是的！服务在那里

我的PDB命名为：pdb1.oradb3.private
