1、執(zhí)行下面這個命令：
TNSPING? DB165
執(zhí)行結果：
TNS Ping Utility for 32-bit Windows: Version 9.2.0.1.0 - Production on 21-12月-2
006 15:53:23

已使用的參數(shù)文件:
E:\oracle\ora92\network\admin\sqlnet.ora
已使用 TNSNAMES 適配器來解析別名
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
(HOST = 192.168.8.165)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = db165)))
OK（20毫秒）
已經(jīng)可以正常的連接了。
2、如果ORACLE8下面的客戶端工具無法使用了，現(xiàn)在可以通過修改這個文件來實現(xiàn)從從本機來連接高版本數(shù)據(jù)庫的作用。
3、在不同版本的oracle之間導入導出數(shù)據(jù)主義一個原則，需要用oracle低版本的工具導入導出數(shù)據(jù)。
