ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务 的解决方法

今天通过Oracle SQL*Plus连接远端服务器的时候提示“监听程序当前无法识别连接描述符中请求服务”,遂在网上找到了解决方案:

①打开Oracle服务器安装目录\NETWORK\ADMIN\listener.ora文件,你会看到如下信息:

 

# listener.ora Network Configuration File: D:\database\Oracle\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\database\Oracle)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ms-c459ece7aa7f)(PORT = 1521))
    )
  )

 

②在(SID_LIST=...)后面添加一句话,其中Demo是Oracle监听的实例名:

 

# listener.ora Network Configuration File: D:\database\Oracle\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\database\Oracle)
      (PROGRAM = extproc)
    )
    (SID_DESC =
       (GLOBAL_DBNAME = V3X)
       (ORACLE_HOME = D:\database\Oracle)   
       (SID_NAME = V3X)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ms-c459ece7aa7f)(PORT = 1521))
    )
  )

 

 

③重启Oracle Listener再连接即可
