"监听程序当前无法识别连接描述符中请求的服务"通常解决办法

修改listener.ora如下：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = H:\Oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
    #增加以下内容   
   (SID_DESC =
      (GLOBAL_DBNAME = test)
      (ORACLE_HOME = H:\Oracle\product\10.2.0\db_1)
      (SID_NAME = test)
    )
  )
