About Oracle Enterprise Manager Cloud Control
Oracle Enterprise Manager Cloud Control (Cloud Control) is a browser-based management interface for Oracle Database. Cloud Control provides a graphical front end and scheduling facilities for RMAN. You enter job parameters, specify a job schedule, and Cloud Control runs RMAN at the designated time or designated repeat interval to conduct the backup and recovery operations.
关于Oracle Enterprise Manager Cloud Control
Oracle企业管理器云控制（Cloud Control）是Oracle数据库的基于浏览器的管理界面。 Cloud Control为RMAN提供了图形前端和调度功能。 您输入作业参数，指定作业计划，Cloud Control在指定时间或指定的重复间隔运行RMAN以执行备份和恢复操作。
Cloud Control provides access to RMAN through a set of wizards. These wizards lead you through a variety of recovery procedures based on an analysis of your database, your available backups, and your data recovery objectives.
Cloud Control通过一组向导提供对RMAN的访问。 这些向导将根据对数据库，可用备份和数据恢复目标的分析，引导您完成各种恢复过程。
By using Cloud Control, you can perform the simpler restore and recovery scenarios outlined in this documentation. You can also use more sophisticated restore and recovery techniques such as point-in-time recovery and Oracle Flashback operations, which allow for efficient repair of media failures and user errors. Using Cloud Control is often simpler than the RMAN command-line client.
通过使用Cloud Control，您可以执行本文档中概述的更简单的恢复和恢复方案。 您还可以使用更复杂的恢复和恢复技术，如时间点恢复和Oracle闪回操作，从而可以有效修复介质故障和用户错误。 使用Cloud Control通常比RMAN命令行客户端更简单。
To use Cloud Control, you start by accessing the Database Home page as described in Accessing the Database Home Page Using Cloud Control
Performing Backup and Recovery Tasks with Cloud Control describes how to use Cloud Control for backup and recovery.
要使用Cloud Control，首先需要访问Database Home页面，如使用Cloud Control访问数据库主页中所述
使用Cloud Control执行备份和恢复任务介绍如何使用Cloud Control进行备份和恢复。
Accessing the Database Home Page Using Cloud Control
The Database Home page is the main database management page in Oracle Enterprise Manager Cloud Control (Cloud Control). After you log in to Cloud Control, you go to the Database Home page for the target database for backup and recovery tasks.
访问数据库主页使用云控制
数据库主页是Oracle Enterprise Manager云控制（云控制）中的主数据库管理页面。 登录Cloud Control后，请转到目标数据库的数据库主页以进行备份和恢复任务。
To access the Database Home page in Cloud Control:
- Start Cloud Control.
The URL for accessing Cloud Control has the following syntax:
http://hostname.domain:portnumber/em
Obtain the URL from your Oracle Enterprise Manager administrator or your
database administrator. - On the Welcome page, enter your Cloud Control user name and password, and
then click Login. - From the Targets menu, select Databases.
- On the Databases page, if not already selected, select Search List to display a list
of the available target databases. - Select the target database that you want to modify by clicking the database name.
The home page for the target database appears. The first time that you interact
with the database (for example, by selecting from the menu options), the Database
Login page appears. - On the login page for the target database, log in as a user with the appropriate
privileges. For example, to log in as user SYS with the SYSDBA privilege:
User Name: Enter SYS
Password: Enter the SYS
user's password.
Connect As: From the list, select Sysdba Role.
