當oracle 報12584錯誤時
一、去把這tnsnames.ora,listener.ora兩個文件裏面的localhost 全部改爲127.0.0.1 包括你連接數據庫用的工具,
改完之後，重啓監聽服務。（重啓監聽服務可以從任務管理器--->服務--->Oracle???Listenter 停止，然後啓動）
如果沒有效果，則繼續下面操作
增加一段代碼至tnsnames.ora配置文件:
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = F:\app\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = ORCL)
)
如圖所示(記得改路徑)：
每次操作完，記得重啓監聽服務。還不行的話直接用我的配置文件把。
