SQL> show parameter service_names

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
service_names                        string      SYS$SYS.KUPC$S_1_2010013113301
                                                 6.MXDELL, mxdell



結束exp動作后還是保持這個service_names, 其他兩個沒有做exp動作的是mxdell, 沒有問題
