1、数据来源。

控制台地址:172.30.252.164:7001/console 登陆: weblogic/weblogic#123
数据库jdbc:oracle:thin:@172.30.252.123:1521:pndb smartposdb_test/CDE#4rfv

根据上面的内容可以得到：

（1）数据库类型是oracle.

（2）采用的是java的jdbc的thin瘦方式连接数据库。

（3）数据库服务器的ip和端口分别是172.30.252.123和1521。

（4）数据库SID是pndb。

（5）数据库服务器的用户名和密码分别是smartposdb_test和CDE#4rfv。

（6）控制台地址就是浏览器中的网址，因此在浏览器中直接输入。控制台的用户名和密码分别是weblogic和weblogic#123。
