在正确安装和配置普元平台以后，我们就可以登录到普元管理控制台 http://localhost:8088/eosmgr 进行更进一步的配置。这里就包括数据库的初始化工作。为了方便起见，我们只需要在oracle的样例数据库ORCL中添加一个用户xuwei，然后将普元的数据库初始化到xuwei账户下。oracle创建用户的方法请参考前一篇博客：使用Oracle SQLDeveloper连接数据库并创建用户。
登录普元管理控制台 http://localhost:8088/eosmgr，然后选择“应用管理->数据库初始化”，填写数据库连接配置，如下图所示。填写完毕以后点击“测试”以验证数据库是否正确连接。
消息：测试数据库连接成功！则表明我的数据库连接时正确的，这时候我们只需要点击“初始化”即可。
不过点击初始化以后会报错，这里我们不需要管这些错误。之所以出现这些错误是因为在创建数据库的时候，在建表前会删除同名的表，但是我们的数据库是空的，所以才会报错。错误如下：

这时候我们连接到ORCL数据库的XUWEI账户下查看新建的数据库表，如下图所示：
一共有57张表，这些表都是普元自带的系统表。在使用普元平台开发系统的时候，我们还需要设计我们自己的数据，只需要往xuwei账户中添加表即可。
