ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务

今天新安装了一个数据库 - XE

创建数据库可以用DCA (Database Configuration Assistant)

 

连接数据库

ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务

 

打开listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = C:\oracle\product\10.2.0)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = C:\oracle\product\10.2.0) 

      (SID_NAME = orcl)

    )

  )

 

加上新的数据库listener配置

 

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = C:\oracle\product\10.2.0)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = C:\oracle\product\10.2.0) 

      (SID_NAME = orcl)

    )
    (SID_DESC =

      (GLOBAL_DBNAME = XE)

      (ORACLE_HOME = C:\oracle\product\10.2.0) 

      (SID_NAME = XE)

    )

  )

 

重起listener服务, 登陆, OK!
