如何在oracle XE中创建数据库？

Question

在甲骨文XE，有一个预装的数据库中，有关员工和部门以及什么的，但我想创建一个新的数据库，我知道我可以在命令行中做到这一点，但我检查了数据库的主页，我只找到创建表，在GUI或浏览器，我需要创建自己的数据库，并让谁只能访问这个数据库，而不是员工数据库

Answer 1

我想你指的“模式”，而不是“数据库”。安装程序会创建一个名为XE的数据库，并且该数据库内部是一个名为HR的模式。要创建其他模式，您可以使用任何Oracle工具（如SQL Plus或Database Control），并且只需创建一个新的用户帐户（因为user = schema）。然而，甲骨文可能更喜欢在SQL Plus是您在使用他们把你的Win2K系统桌面上的快捷方式访问您的计算机上的XE“主页”，然后单击管理链接

我有这个链接，你的用户。 Go through it。
你可能会觉得它有帮助。

编辑：我已经改变了链接，请再次提及...

Answer 3

在甲骨文XE我觉得有点不可思议;你必须创建一个用户。以该用户身份登录，然后创建数据库对象。

您可以从所谓的数据库主页做到了;如果你想真正探索你的选择;在创建用户之后;你可以安装sql开发人员并与之连接;它对我来说更直观。

保存在一个批处理文件（例如：createOraDbWin.bat）下面的代码。更改参数值，如app_name，ora_dir等。使用管理权限运行该文件。该批处理文件创建一个基本的Oracle数据库：

注：可能要花费很多时间（大约基于资源可用性30分钟）

这里与丢弃IMG的快照文本模式步骤...

“”“先决条件：应具有管理员权限

‘’”这个文件只包括甲骨文XE的Microsoft Windows版本只有

'''我这样做是为Oracle XE11克....我希望它是相同的Oracle XE的所有版本....

1）安装Oracle XE

2）确保您记下了您在安装过程中提供的系统密码。通过点击入门页面 -

3）安装后点击Start Database

4）打开Oracle网络仪表盘，启动Oracle XE服务。

5）在Web仪表板中创建新用户。

a. In the Getting Started web page, click on – “Application Express” 

b. Login as system user 

c. Now create new-user under Application Express, give the db-username,application-express-user-name as same for convenience. 

6）一旦创建了DB_USER，开放sql_plus

7）connect sys as sysdba并给system用户密码，

8）格兰特SYSDBA角色创建-DB

grant sysdba to {database};例如grant sysdba to pcbscheduler;

9）现在你已经完成了在XE中创建新的数据库（因为它李）

10）尝试从Oracle SQL Developer连接。
