因为要做毕业设计，所以就给我的windows7 小系统安装了个10g的oracle数据库，安装上以后我的小电脑非常的慢，所以我把就OracleOradb10g_home2TNSListener,OracleJobSchedulerORCL,OracleDBConsoleorcl三个服务给关掉了，这样的话用命令行还是可以用数据库的，但是如果用jdbclpk连数据库的话就会报错：java.sql.SQLException: Io 异常: The Network Adapter could not establish
the connection，这时候把OracleOradb10g_home2TNSListener这个服务开起来就不会再出现这个问题了，不过出现这个问题的原因也可能是其它原因造成的，比如ip地址，端口号，或数据库的名字写错等，这个错误就是说不能连接数据库了，具体是什么问题就具体分析了
