Oracle11g Oracle XE停止工作。TNS侦听器拒绝连接

我正在开发一个使用OracleXe11g作为RDBMS的应用程序。它已经工作了几个星期，但现在我开始收到一条关于连接被拒绝的错误消息

我重新启动了我的系统，但它没有帮助。我卸载了XE，删除了所有剩余的文件（甚至是从注册表中），然后重新安装了它。现在我收到另一条错误消息：

侦听器拒绝连接，出现以下错误：ORA-12505， TNS:侦听器当前不知道connect中给定的SID 描述符

我已经阅读了有关此错误的信息，其他人建议将新SID添加到listener.ora文件：

(SID_DESC =
  (SID_NAME = XE)
  (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
)

如果执行此操作，则会收到另一条错误消息：

ORA-01034:ORACLE不可用ORA-27101:共享内存领域不可用 不存在

我的配置文件是： listener.ora

你知道有什么问题吗？我不是甲骨文专家，所以我对这里一无所知。

您的甲骨文数据库已关闭。它可能在启动时遇到一些问题

转到命令提示符并键入：

SQL>sqlplus/as sysdba

    SID_LIST_LISTENER =   (SID_LIST =
    (SID_DESC =
      (SID_NAME = XE)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
    )
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )   )

LISTENER =   (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = AAROLD.in.mycompany.com)(PORT = 1521))
    )   )

DEFAULT_SERVICE_LISTENER = (XE)

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = AAROLD.in.mycompany.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

ORACLR_CONNECTION_DATA = 
  (DESCRIPTION = 
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

      (SID = CLRExtProc) 
      (PRESENTATION = RO) 
    ) 
  ) 

如果收到消息“已连接到空闲实例”，请键入

SQL>启动

让我知道你得到的信息。如果在SqlPlus启动时未收到“连接到空闲实例”消息，则类型：

SQL>设置行80页50

SQL>从v$数据库中选择*

---

然后在这里发布输出。

我遇到了完全相同的问题，花了将近4个小时试图找到答案，最后添加了

(SID_DESC =
  (SID_NAME = XE)
  (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
)

到my listener.ora并重新启动这两个XE服务解决了问题。直到昨天，我还在Windows7x64上使用11.2.0（XE），没有任何问题。今天早上我的电脑重新启动导致侦听器找不到SID

现在我正在备份listener.ora和tnsnames.ora

---

顺便说一句，忘了提及我将两个文件中的主机名从bob.mycompany.com更改为localhost。

在Windows 7 64位或CALE XE 11上 我的OracleXXETNSListener服务没有运行，并且在我尝试启动它时立即终止

添加

（SID_DESC=（SID_NAME=XE）（ORACLE_HOME）= C:\oraclexe\app\oracle\product\11.2.0\server）

对我

将主机名更改为localhost

重新启动系统-服务下的OracleServiceXE服务解决了问题

因此，完整的listener.ora部分如下所示：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\servers\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\servers\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = XE)
      (ORACLE_HOME = C:\servers\oraclexe\app\oracle\product\11.2.0\server)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

更新： 5年后的今天，我在Win10上遇到了与OracleXE 18c相同的问题。TNS侦听器在成功安装后不会立即启动，因为oracleXE\dbhomeXE\NETWORK\ADMIN\listener.ora

---

指向localhost.docker.internal而不是localhost。

我遇到了一个类似的问题，我通过从listener.ora和tnsnames.ora中删除“IPC”行修复了它

在

listener.ora

上，我删除了：

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

在

tnsnames.ora

上，我删除了：

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

---

这可能有点过分了，但几个小时后终于修好了

我也遇到了同样的问题，错误是我更改了我机器的名称。通过编辑listener.ora并重命名主机解决了此问题：

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = hostname_of_my_machine)(PORT = 1521))
    )
  )

您是否尝试启动数据库？请搜索“oracle xe启动数据库”将引导您找到有希望的信息。这没有帮助。我仍然收到相同的错误消息。请重新运行lsnrctl status以查看数据库是否已注册。我得到的输出与您在我的帖子中看到的完全相同。那是什么意思？我已经试过了。提示将启动，但如果我尝试连接，则会收到一条错误消息，说明oracle无法检查凭据。我知道SYS和系统用户的密码，只是不起作用。谢谢！现在，第二个有趣的部分是为什么Oracle配置会自动停止工作…？是的，知道这一点很有意思。我的Oracle今天停止工作，并将其添加到我的listener.ora（以及本论坛其他有用答案中建议的许多启动和停止）修复了该问题。然而，这些线路以前是不必要的。其间发生的只是一次蓝屏致命的崩溃，这很可能与Oracle无关。将此更改为上述localhost是否意味着重命名计算机不会再次破坏它？
