ORA-12514问题解决

版本：11.2.0.1.0 - 64bit

本机安装Oracle后链接测试发现以下情况：

sqlplus scott/tiger 正常登陆

sqlplus scott/tiger@orcl  登陆失败，提示ORA-12514错误，应该是无法识别服务名ORCL

为此查阅资料，找到以下解决方案：

-------------------------------------------------------------------

找到oracle安装目录下listener文件：

原文件如下：

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


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


ADR_BASE_LISTENER = d:\app\Administrator

修改后如下：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = d:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:d:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
   (SID_DESC =
       (GLOBAL_DBNAME = ORCL)
       (ORACLE_HOME = d:\app\Administrator\product\11.2.0\dbhome_1)  
       (SID_NAME = ORCL)
   )
  )


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


ADR_BASE_LISTENER = d:\app\Administrator

保存，后sqlplus scott/tiger@orcl 可正常登陆。
