Oracle XE停止了工作.TNS听众拒绝连接

Question

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.

我重新启动了系统,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:

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

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,我收到另一条错误消息:

ORA-01034:ORACLE不可用ORA-27101:共享内存域不存在

我的配置文件是: listener.ora

    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)

tnsnames.ora中

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

lsnrctl status返回:

你知道这可能是什么问题吗？我不是Oracle专家,所以我在这里完全处于黑暗中.

Answer 1

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.

现在我要备份listener.ora和tnsnames.ora.

顺便说一句,忘了提到我将bob.mycompany.com的文件中的主机名更改为localhost.

Answer 2

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

1. 添加

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

对我的

C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora

2. 将主机名更改为localhost

3. 在System - Services下重新启动OracleServiceXE服务解决了这个问题.

所以完整的listener.ora部分看起来像:

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)

Answer 3

您的 Oracle 数据库已关闭。启动时可能会出现一些问题。

转到命令提示符并键入：

SQL> sqlplus / 作为 sysdba

如果您收到一条消息“已连接到空闲实例”，则键入

SQL>启动

并让我知道您收到的消息。如果在 SqlPlus 启动时没有收到“连接到空闲实例”消息，请输入：

SQL>设置第 80 行第 50 页

SQL>从 v$database 选择*；

并在此处发布输出。
