2.4. Managing Backups with Enterprise Manager

Managing backup can be configured using Enterprise Manager (EM). As stated in Chapter 1, "Configuring Recovery Manager," EM is a web-based console that allows most DBA activities to be performed from a GUI screen instead of from the typical command-line interface (CLI).

NOTE

In the examples in this book, you have installed Database Control opposed to Grid Control, which is an additional software component to support 10g Grid Control options.

The following steps demonstrate how to access EM Database Control. Once in the web application, you will see the screens that are capable of modifying managing backups. Let's look at the EM Database Control screens that allow the management of RMAN backups:

  1. First, enter http://hostname.domain:5500/em in the web browser. The hostname is the name of the server or computer that you are running EM on. In this example, the hostname is dstuns-xp. The domain is the network domain that you have EM installed on. The domain value will vary depending on the network that you are running EM on. This will take you to the EM Database Control home page, where you can find the following login screen. At this point, enter the username SYS and SYS accounts passwords and connect as SYSDBA.



  2. After you log in, the EM Database Control home page appears. (Notice that we saved this as two screens because of the size.) Choose the Maintenance tab to navigate to the maintenance screens that contain the screens that allow configuration modifications.



  3. On the Maintenance screen, in the Backup/Recovery section, click the Manage Current Backups link, which will navigate to the Manage Current Backups screen available in EM Database Control.



  4. On the Backup Set tab, notice four buttons: Catalog Additional Files, Crosscheck All, Delete All Obsolete, and Delete All Expired. These are the backup management options with EM.



NOTE

It is important to know that the Windows Administrator account or an account with the same privileges should be used in the Host Credentials section of the Manage Current Backups screen for the Windows environment. In a Unix environment, the Oracle user or similar privileged account should be used. This is because the EM Database Control web applications essentially host out to the operating system to execute these commands with the RMAN command-line interface
