Oracle XE停止了工作。 TNS听众拒绝连接

标签: oracle11g database-connection

我正在开发一个使用Oracle XE 11g作为其RDBMS的应用程序。它工作了几个星期,但现在我开始收到有关连接被拒绝的错误消息。

我重启了系统,但没有帮助。我卸载了XE,删除了所有剩余的文件(甚至从注册表中删除)并重新安装它。现在我收到另一条错误消息:

  

侦听器拒绝连接时出现以下错误:ORA-12505,   TNS:监听器当前不知道connect中给出的SID   描述符

我已经读过这个错误,其他人建议在listener.ora文件中添加一个新的SID:

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

如果我这样做,我会收到另一条错误消息:

  

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

我的配置文件是: 的的listener.ora

    SID_LIST_LISTENER =   (SID_LIST =

你知道可能出现什么问题吗?我不是Oracle专家,所以我在这里完全处于黑暗中。

我有完全相同的问题,花了将近4个小时试图找到并回答,最后添加

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

到我的listener.ora并重启两个XE服务解决了这个问题。我在Windows 7 x64上使用11.2.0(XE),直到昨天都没有任何故障。今天早上重启我的电脑导致听众找不到SID。

现在我正在备份listener.ora和tnsnames.ora。

顺便说一句,忘记提及我将bob.mycompany.com中的文件中的主机名更改为localhost。

在Windows 7 64位,Orcale XE 11上 我的OracleXXETNSListener服务没有运行,并在我尝试启动时立即终止。

  1. 添加
  2.   

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

    到我的

    C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora
    
    1. 将主机名更改为 localhost

    2. 系统 - 服务下的
    3. 重新启动OracleServiceXE服务解决了这个问题。

    4. 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)
      

答案 2 :(得分:3)

我有类似的问题,我通过删除" IPC"来自listener.ora和tnsnames.ora的行。

listener.ora,我删除了:

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

tnsnames.ora,我删除了:

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

这可能是一种矫枉过正,但几个小时后它终于得到了修复!

答案 3 :(得分:2)

您的Oracle数据库已关闭。启动时可能会遇到一些问题。

转到命令提示符并键入:

SQL> sqlplus / as sysdba

如果收到“连接到空闲实例”的消息,请键入

SQL>的启动

让我知道你得到的信息。如果在SqlPlus启动时没有收到“连接到空闲实例”消息,则输入:

SQL> 设置行80页50

SQL> 从v $ database中选择*;

并在此处发布输出。

答案 4 :(得分:1)

我遇到了同样的问题,错误是我更改了我的机器名称。这是通过编辑listener.ora并重命名HOST来解决的:

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