操作步骤:

1. File菜单->New->User;

2. A窗口显示;分别选择标签显示B、C、D、E窗口。

说明:创建一个用户,需要确定用户名,口令,然后赋予用户一定的权限、规则、系统权限,和占用表空间的配额。

The user definition editor

The user editor allows you to create or modify a user, its privileges, and tablespace quotas:

Note that you need specific system privileges (such as provided by the DBA role) to view and modify user information.

General page

On the general page you basically only need to enter the name and password. All other properties have a default value:

  • Default tablespace ?SYSTEM

  • Temporary tablespace ?SYSTEM

  • Profile ?DEFAULT

  • Password expire ?Off

  • Account Locked ?Off

If you modify an existing user, the current password will not be displayed. Enter a new password to change it, or leave it empty to leave the password unchanged. If the user is identified externally, you cannot enter a password.

用户定义编辑器(原创图示一A图)

使用用户编辑器允许你创建、修改用户和分配用户权限及表空间;

注意:你需要指定系统权限例如DBA规则的提供来显示和修改用户信息;

基本标签页

在基本标签页,你主要工作只需要键入用户名和口令。而其它的属性都有默认值:

  • 默认表空间-SYSTEM
  • 临时表空间-SYSTEM
  • 配置文件-DEFAULT
  • 口令过期-关闭
  • 帐号锁定-关闭

如果你想修改已经存在的用户,则当前使用口令不被显示。输入一个新口令可以更改,或者不输入口令(即空着)则未有更改。如果用户使用外部认证,则你不能输入口令。

Object privileges page

This page allows you to view and modify the object privileges granted to the user. This does not include the privileges that are indirectly granted through a role.

In the first column you can see the object on which privileges are granted to the user. All other columns represent a specific privilege. Each privilege can have the following value:

  • (Blank) ?The user does not have the privilege

  • Yes ?The user has the privilege

  • Grantable ?The user has the privilege, and can grant it to other users or roles

对象权限页(原创图示一B图)

这个页面允许你查看和修改赋予用户的对象的权限。这里面不包括通过一些规则间接的赋予的权限。

在第一行,可以看到赋予用户权限的对象。而其它行表示指定的权限。每个权限可以被赋予下列值:

  • 空-指用户不具有该权限
  • 是-指用户具有该权限
  • 可授予的-指用户有该权限,可以通过其它用户或规则来授予

Role privileges page

image.IMG00062.gif

This page displays the roles that are granted to the user. Each role privilege can be grantable, so that the user can grant it to other users and roles. If a role privilege is default, the role will be enabled when the user logs on. If it is not default, the role privilege must explicitly be enabled for the session by executing a set role command after the user has logged on.

规则权限页(原创图示一C图)

这个页面显示赋予用户的规则权限。

如果规则权限是“被赋予的”,则其它用户或规则就可以赋予。

如果规则权限是“默认”,则当用户登录后即可使用规则。

如果规则权限不是默认的,则在用户登录后,需要执行“SET ROOL”命令,必须明确的指出可以行驶权限的进程。

System privileges page

系统权限页(原创图示一D图)

这个页面显示赋予用户的系统的权限。系统权限设置为“被赋予的”,则用户可以被其它的用户或规则赋予相关权限。
