连接Oracle 10g时ORA-12514: TNS: 监听进程不能解析在连接描述符中给出的 SERVICE_NAME 错误的解决

解决方法：
1. 打开<OracleHome>/network/admin/listener.ora文件，找到：

   SID_LIST_LISTENER =
   (SID_LIST =
     (SID_DESC =
       (SID_NAME = PLSExtProc)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
       (PROGRAM = extproc)
     )
   )
  2. 添加：
            (SID_DESC =
       (GLOBAL_DBNAME = ORACLE)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) 
       (SID_NAME = ORACLE)
      )
  3. 最后变成：
 SID_LIST_LISTENER =
   (SID_LIST =
     (SID_DESC =
       (SID_NAME = PLSExtProc)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
       (PROGRAM = extproc)
     )
     (SID_DESC =
       (GLOBAL_DBNAME = ORACLE)
       (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) 
       (SID_NAME = ORACLE)
      )
   )
  4. 保存文件，重启服务中的TNSListener，OK！
