Oracle 常见问题

1. ORA-12514:TNS:监听程序当前无法识别连接描述符中请求的服务。

 

  将listener.ora文件修改成如下就可以:

  SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl
      (ORACLE_HOME = D:/oracle/product/10.2.0/db_1)
      (SID_NAME = orcl)
    )
  )

 

  关闭监听：lsnrctl stop

  启动监听：lsnrctl start
