帮助Task Center用户快速迁移到Job Manager
Job Manager 是 Data Studio web console 产品中提供的替代 Task Center 的功能。Data Studio web console 是一款基于 web 的产品，可以方便地通过浏览器访问。
本文旨在帮助 Task Center 用户快速迁移到 Job Manager。它指导您如何使用 Job Manager 来执行 Task Center 工具中提供的相同管理任务等。本文主要从 Job Manager 与 Task Center 的不同之处进行比较，介绍 Job Manager 如何创建，调试，运行，浏览 Job。如何从 Task Center 导入任务到 Job Manager，以及 Job Manager 不兼容的任务和调度。
IBM Data Studio 包含三个独立的功能组件：Data Studio 完整客户端，Data Studio 管理客户端，Data Studio web 控制台（DSWC）DSWC 是独立的 web 应用，也可以和 Data Studio 集成使用。DSWC 提供对的健康监控工具和作业创建与管理工具。Job Manager 就是 DSWC 提供的替代 Task Center 的作业管理工具。
Job Manager 最早发布于 2011 年 10 月，包含在 DSWC 3.1 版本中。DSWC 3.1.1 版于 2012 年 4 月推出，其中 Job Manager 有一些功能的增强，还增加了从 Task Center 导入任务的新功能。
要使用 Job Manager，用户需要安装 DSWC。与 Task Center 不同的是，用户安装好 DSWC 后，可以通过浏览器在任何机器上进行访问，而不仅是在安装 DSWC 的机器上访问。安装了 Data Studio 基于 Eclipse 的客户端（完整客户端或者管理客户端）的用户如果想从该客户端访问 Job Manager，必须先安装 DSWC 并在客户端进行配置。从 Data Studio 信息中心 Getting Started 章节了解更多关于安装和使用的信息。
存储数据库 vs 工具目录数据库
使用 Task Center 必须配置工具目录数据库，用于保存任务信息。要使用 Task Center，用户必须先配置好工具目录数据库。与之对应的是，Job Manager 中的作业数据都保存在存储数据库中。实际上，DSWC 的共享数据，管理信息等都存放在存储数据库中。
用户可以指定一个数据库作为存储数据库，也可以使用 DSWC 自带的一个数据库（如果用户不指定存储数据库，该数据库是系统默认的存储数据库）。
用户通过以下步骤配置存储数据库：
- 从“打开”目录中选择“配置库”页面打开它，如图 1；或者直接从打开的“任务启动程序”页面中点击“选择存储库数据库”打开“配置库”页面，如图 2。

- 在“配置库”页面点击“选择存储库数据库”按钮，如图 3；在打开的“编辑数据库连接概要文件”对话框中输入数据库信息，点击确定。添加成功后，用户会看到“配置库”页面显示的存储库数据库信息和状态，如图 4。

Log in to Ubuntu as superuser
Mar 20, 2024 am 10:55 AM
In Ubuntu systems, the root user is usually disabled. To activate the root user, you can use the passwd command to set a password and then use the su- command to log in as root. The root user is a user with unrestricted system administrative rights. He has permissions to access and modify files, user management, software installation and removal, and system configuration changes. There are obvious differences between the root user and ordinary users. The root user has the highest authority and broader control rights in the system. The root user can execute important system commands and edit system files, which ordinary users cannot do. In this guide, I'll explore the Ubuntu root user, how to log in as root, and how it differs from a normal user. Notice

What is sudo and why is it important?
Feb 21, 2024 pm 07:01 PM
sudo (superuser execution) is a key command in Linux and Unix systems that allows ordinary users to run specific commands with root privileges. The function of sudo is mainly reflected in the following aspects: Providing permission control: sudo achieves strict control over system resources and sensitive operations by authorizing users to temporarily obtain superuser permissions. Ordinary users can only obtain temporary privileges through sudo when needed, and do not need to log in as superuser all the time. Improved security: By using sudo, you can avoid using the root account during routine operations. Using the root account for all operations may lead to unexpected system damage, as any mistaken or careless operation will have full permissions. and

The whole step is very simple. The user imports the picture in the new layout application, and then clicks the "removebackground" button on the toolbar to delete the background in the picture. The user can also use a rectangle to select the area to remove the background.
