如何在oracle XE中创建数据库？

Question

在oracle XE中，有一个预安装的数据库，关于员工和部门等等，但我想创建一个新的数据库，我知道我可以在命令行中完成，但我查了数据库主页，我只发现创建表，在GUI或浏览器中，我需要创建自己的数据库，并使一个只能访问该数据库而不是员工数据库的用户

Answer 1

  

我认为你的意思是＆＃34;架构＆＃34;而不是＆＃34;数据库＆＃34;。安装程序创建名为XE的数据库，该数据库内部是名为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，您所要做的就是创建一个新的用户帐户（因为user = schema）。但是，Oracle可能比SQL Plus更喜欢的是您访问XE＆＃34; Home Page＆＃34;在计算机上使用他们放在Win2K桌面上的快捷方式，然后单击“管理”链接

以下是文本模式中的步骤，其中img-snapshots被丢弃......

＆＃39;＆＃39;＆＃39;先决条件：应具有管理员权限

＆＃39;＆＃39;＆＃39;本文档仅涵盖Microsoft Windows版本的Oracle XE

＆＃39;＆＃39;＆＃39;我已经为Oracle XE 11g做了这个....我希望所有版本的Oracle XE都一样....

1）安装Oracle XE

2）确保您记下了在安装过程中提供的系统密码。

3）安装完成后，单击Start Database

启动Oracle XE服务

4）打开oracle web仪表板， - 单击“入门”页面。

5）在网络信息中心中创建新用户。

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）创建db_user后，打开sql_plus

7）connect sys as sysdba并提供system用户密码，

8）将sysdba角色授予created-db

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

9）现在你已经完成了在XE中创建新数据库（因为它限制了。）

10）尝试从Oracle SQL Developer进行连接。

Answer 4

在oracle xe中我发现它有点奇怪;你必须创建一个用户。以该用户身份登录，然后您可以创建数据库对象。

您可以从所谓的数据库主页进行此操作;如果你想真正探索你的选择;在您创建用户之后;你可以安装sql developer并与之连接;它对我来说更直观。

将以下代码保存在批处理文件中（例如createOraDbWin.bat）。更改app_name，ora_dir等参数值，使用管理权限运行文件。批处理文件创建一个基本的oracle数据库：
