Oracle侦听器未运行且无法启动

普拉纳夫·纳斯

我从lsnrctl status命令中收到以下错误：

C:\Users\pna105>lsnrctl stat

在重新启动之前，它工作正常，但现在不工作，而且我也无法访问我的Oracle主页。

我的tnsnames.ora是：

  ORACLE = 
  (DESCRIPTION =  
    (ADDRESS_LIST =  
      (ADDRESS = (PROTOCOL = TCP)(HOST = Localhost)(PORT = 1521))  
    )  
    (CONNECT_DATA =  
      (SERVICE_NAME = ORACLE)  
    )  
   )

   LISTENER_ORACLE =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


  ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
  )
   (CONNECT_DATA =
   (SID = CLRExtProc)
   (PRESENTATION = RO)
  )
  )

我的listener.ora是：（这是由于括号放错位置而导致的错误，增加了几个空格，从而解决了TNS-12518的问题）

   SID_LIST_LISTENER =
   (SID_LIST =
   (SID_DESC =
    (SID_NAME = ORACLE)
    (ORACLE_HOME = C:\app\PNA105\product\11.2.0\dbhome_1)
  )  
  (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = C:\app\PNA105\product\11.2.0\dbhome_1)
    (PROGRAM = extproc)
   )
   (SID_DESC =
  (SID_NAME = CLRExtProc)
  (ORACLE_HOME = C:\app\PNA105\product\11.2.0\dbhome_1)
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=ONLY:C:\app\PNA105\product\11.2.0\dbhome_1\bin\oraclr11.dll")
  )
  )

  LISTENER =
 (DESCRIPTION_LIST =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
  )
  )

  ADR_BASE_LISTENER = C:\app\PNA105

以下是lsnrctl start命令的输出

试图解决TNS-12518，并且侦听器已启动，但仍然无法访问Oracle主页

命令成功完成

皮特·凯普卡（Piotr Kepka）

1.检查环境变量（必须为系统而不是用户设置）：

ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server
ORACLE_SID = XE

2.检查listener.ora中的定义是否正确

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

DEFAULT_SERVICE_LISTENER = (XE)

3.重新启动服务（服务> OracleServiceXE）

之后，您可能会看到一个名为OracleXETNSListenerXE的新服务。
已经有一个旧的OracleXETNSListener。

我同时启动了这两个程序，然后建立了成功的连接。

编辑：

如果一切正常，但是仍然无法连接，请检查是否没有错误：ORA-12557：TNS：协议适配器不可加载。

要更正错误，请返回到Environment变量，这次编辑一个叫做Path的变量。确保C：\ oraclexe \ app \ oracle \ product \ 11.2.0 \ server \ bin位于开头，肯定在指向其他版本的Oracle DB的其他路径之前。
