This chapter introduces the interfaces that you can use with Oracle Secure Backup. The major interfaces to Oracle Secure Backup are:
Oracle Enterprise Manager
This is the primary graphical user interface for managing Oracle Secure Backup.
Oracle Secure Backup Web tool
This interface is used to manage file-system level backups and to perform certain other tasks not possible in Oracle Enterprise Manager.
This command line client exposes the full functionality of Oracle Secure Backup and is invoked by the Oracle Secure Backup Web Tool and Oracle Enterprise Manager.
Note:
Database backups are performed using Recovery Manager (RMAN). Because backup and recovery activities are discussed in Oracle Secure Backup Administrator's Guide and Oracle Database Backup and Recovery Advanced User's Guide, RMAN is not discussed in this chapter.
All backup and restore operations in Oracle Secure Backup ultimately call upon a command line tool called obtar. It is generally not necessary to call obtar directly. See Oracle Secure Backup Reference for more details about obtar.
This chapter contains these sections:
You can use Oracle Enterprise Manager 10g (10.2) or Oracle Enterprise Manager 11g to perform most Oracle Secure Backup tasks, including administrative domain and hardware configuration, managing your media, and backing up and restoring databases. Oracle Enterprise Manager is the preferred Web interface for Oracle Secure Backup tasks.
However, you cannot use Oracle Enterprise Manager to perform file-system backup and restore operations. The Maintenance page in Oracle Enterprise Manager includes a link to the Oracle Secure Backup Web tool for such tasks.
This document describes the use of Oracle Enterprise Manager for most tasks, and describes the Oracle Secure Backup Web Tool only when there is no equivalent functionality in Enterprise Manager.

Enabling Oracle Secure Backup Links in Oracle Enterprise Manager
Registering an Administrative Server in Oracle Enterprise Manager
If you are using releases 10.2.0.1 or 10.2.0.2 of Oracle Enterprise Manager Grid Control or release 10.2.0.2 of Oracle Enterprise Manager Database Control, then the Maintenance page does not include the Oracle Secure Backup section by default. If the Oracle Secure Backup section does not appear in the Maintenance page, then you must configure Oracle Enterprise Manager to enable the links.
To enable the Oracle Secure Backup section in Oracle Enterprise Manager:
Go to the ORACLE_HOME
/
hostname_SID
/sysman/config
directory and open the emoms.properties file in a text editor.
Set osb_enabled=true
and save the file.
Stop and restart the Oracle Enterprise Manager Database Control console with the emctl
command:
emctl stop dbconsole emctl start dbconsole
Go to the Maintenance page and confirm that the Oracle Secure Backup section appears, as shown in Figure 4-1.
You can make RMAN backups to the Oracle Secure Backup SBT interface three ways:
Oracle Enterprise Manager Database Control
Oracle Enterprise Manager Grid Control
RMAN command-line client
The Database Control console must run on the administrative server and can only back up an Oracle database on the administrative server. You can run the Grid Control console on any database host in the administrative domain and use it to back up any database. This section describes how to get started with Database Control.
To use Enterprise Manager to manage your backups, you must make Enterprise Manager aware of your administrative server, which stores the configuration data and catalog for the Oracle Secure Backup administrative domain. To register the administrative server in Oracle Enterprise Manager Database Control:
Log in to the Oracle Enterprise Manager Database Control console as a user with database administrator rights.
In the Oracle Secure Backup section, click Oracle Secure Backup Device and Media.
The Add Administrative Server page appears.
Log in to your Oracle Secure Backup administrative domain as follows:
Enter the Oracle Secure Backup home directory in the Oracle Secure Backup Home field. This directory is usually /usr/local/oracle/backup
on UNIX and Linux and C:\Program Files\Oracle\Backup
on Windows.
Enter the name of an Oracle Secure Backup administrative user in the Username field. For example, enter admin
.
Enter the password for the Oracle Secure Backup administrator in the Password field.
Click OK.
The Host Credentials page appears.
Enter the username and password of the operating system user on the administrative server. This user needs root
privileges.
The Oracle Secure Backup Device and Media: Administrative Server: hostname page appears. You can use this page to load tapes.
After you have registered the administrative server, you are ready to use Oracle Enterprise Manager with Oracle Secure Backup.

You can use this link when you need access to Oracle Secure Backup Web tool functions, such as file-system backup information.
To access the Oracle Secure Backup Web tool through Oracle Enterprise Manager Database Control:
Log in to the Oracle Enterprise Manager Database Control as a user with database administrator rights.
Go to the Oracle Secure Backup section of the Maintenance page.
If the Oracle Secure Backup section does not appear in the Maintenance page, then see "Enabling Oracle Secure Backup Links in Oracle Enterprise Manager".
Click File System Backup and Restore.
The Oracle Secure Backup Web tool interface opens, as described in "Starting a Web Tool Session".
The Oracle Secure Backup Web tool is a browser-based interface that does not require installation of Oracle Enterprise Manager. It is also the only graphical interface to the file-system backup capabilities of Oracle Secure Backup.
Note:
You can access all functionality of Oracle Secure Backup through the Oracle Secure Backup Web Tool, including file-system level backups. However, Oracle Enterprise Manager is the preferred interface for most functionality, and provides the only graphical interface for Oracle Database backups to tape.You can access the Oracle Secure Backup Web tool from any supported browser that can connect to the administrative server through SSL. The Apache Web server supplied with Oracle Secure Backup must be running to respond to these requests. Supported browsers are listed on Certify on My Oracle Support, at the following URL:
Note:
The PHP software installed with Oracle Secure Backup is not supported for direct use by customers. It is only supported for use in implementing the Oracle Secure Backup Web tool.This section contains these topics:
This section explains how to use the Oracle Secure Backup Web tool to access your Oracle Secure Backup administrative domain.
To start an Oracle Secure Backup Web tool session:
Launch your Web browser and supply the URL of the host running Oracle Secure Backup. Use the following syntax, where hostname can be a fully qualified domain name:
https://hostname
For example, you might invoke the following URL:
https://osblin1.oracle.com
The browser displays a warning that the certificate is not trusted. Oracle Secure Backup installs a self-signed certificate for the Apache Web server. The Web server requires a signed certificate for data encryption purposes. The security warning appears because the browser does not recognize the signer as a registered Certification Authority (CA). This alert does not mean that your data is not encrypted, only that the CA is not recognized.
Accept the certificate. It is not necessary to view the certificate or make any configuration changes.
The Oracle Secure Backup Login page appears.
Enter an Oracle Secure Backup user name in the User Name box and a password in the Password box.
If you are logging into the Oracle Secure Backup Web tool for the first time, then log in as the admin
user. You can create additional users after you log in.
Note:
Oracle recommends that you not use browser-based password managers to store Oracle Secure Backup passwords.Click Login. The Oracle Secure Backup Home page appears.
The Home, Configure, Manage, Backup, and Restore tabs are explained in detail in the following sections.
After you log in to the Oracle Secure Backup Web tool interface, the Oracle Secure Backup Home page appears. This page provides a summary of the current status of each Oracle Secure Backup job and tape device. Figure 4-2 shows an example of the Home page.
Figure 4-2 Oracle Secure Backup Home Page
The main page includes the schedule times, status, job IDs, job type, and job level of recent jobs. Oracle Secure Backup provides a link for failed jobs, alerting users and administrators to potential trouble spots.
The Devices link lists the tape devices associated with each job along with information concerning tape device type, device name, and status. This page provides you with an overall picture of the various backup or restore processes that are going on.
Note:
A status of "device not in use" means that the tape device is present but is not currently being utilized for backup or restore operations.A menu bar at the top of the Oracle Secure Backup Home page enables you to select among the Configure, Manage, Backup, and Restore tabs.
Note:
When using the Oracle Secure Backup Web tool, ensure that your browser is configured to reload the page every time it is viewed. Otherwise, the browser might display stale information. For example, changes made in obtool might not be visible in the browser.The top and bottom panels of the Home page, and every page of the Oracle Secure Backup Web tool interface, have the following persistent links:
Help
Use this link to access online documentation for Oracle Secure Backup in PDF format.
Logout
Logs the current user out of the Oracle Secure Backup Web tool, clears user name and password cookies, and returns to the Login page.
Preferences
Use this link to access settings for the following options:

obtool is the primary command-line interface to Oracle Secure Backup. The obtool
executable is located in the bin subdirectory of the Oracle Secure Backup home. You can start obtool
on any host in the administrative domain, log in to the domain as an Oracle Secure Backup user, and issue commands.
Note:
All examples in this section assume that the bin subdirectory of the Oracle Secure Backup home is in your PATH.This section contains these topics:
See also:
Oracle Secure Backup Reference for a more detailed discussion of invokingobtool
and for more information on obtar, which is mostly used internally by obtool
Assuming that the bin subdirectory of the Oracle Secure Backup home is in your system path, you can obtain online help about obtool invocation options by running the following command at the operating system prompt:
% obtool help invocation
Enter obtool
at the command line to use obtool in interactive mode.
The first time you invoke obtool
, you are required to establish your identity as an Oracle Secure Backup user. If you have not yet established a user identity, then obtool
prompts you for a user name and password.
Note:
The installer for Oracle Secure Backup creates theadmin
user automatically, and prompts for a password. Use these credentials when you log in to Oracle Secure Backup for the first time after installation.
The practice of supplying a password in clear text on a command line or in a command script is not recommended by Oracle. It is a security vulnerability. The recommended procedure is to have the user be prompted for the password.
You can enter the commands described in Oracle Secure Backup Reference at the obtool prompt. For example, the lshost
command displays information about the hosts in your administrative domain:
ob> lshost brhost2 client (via OB) in service brhost3 mediaserver,client (via OB) in service br_filer client (via NDMP) in service stadv07 admin,mediaserver,client (via OB) in service
You can use the <
command in interactive mode to read text files containing multiple obtool commands. For example, you can create a file called my_script.txt with multiple obtool
commands and redirect the obtool
input to this script as follows:
ob> < /my_dir/my_script.txt
obtool
runs the commands from the file and then returns to the ob>
prompt for your next command.
You can run obtool in noninteractive mode from the Linux or UNIX shell or from the Windows command prompt with arguments that specify the command to run. obtool
runs the specified command immediately and exits. Use the following syntax:
obtool [ cl-option ]... command-name [ option ]... [ argument ]...
The following example runs the lshost
command and then returns to the operating system prompt:
% obtool lshost Output of command: lshost brhost2 client (via OB) in service brhost3 mediaserver,client (via OB) in service br_filer client (via NDMP) in service stadv07 admin,mediaserver,client (via OB) in service %
You can run multiple commands in one invocation of obtool by separating the commands with a semicolon on the command line.
Note:
Follow the quoting conventions of your host operating system shell or command line interpreter when entering a semicolon in the command line. For example, in a bash shell session, quote the semicolon as follows:$ obtool lshost ';' lsdev
You can use the <
command in noninteractive mode to read text files containing multiple obtool commands. For example, you can create a file called my_script.txt with multiple obtool
commands and redirect the obtool
input to this script as follows:
% obtool < /my_dir/my_script.txt
obtool
runs the commands from the file and then returns to the operating system prompt for your next command.
You can end an obtool session by using one of these commands:
exit
This command ends the obtool
session, but a login token preserves your credentials, so that the next time you start obtool
you are not prompted for a user name or password.
quit
This command is a synonym for exit
.
logout
This command ends the obtool
session and destroys the login token, so that you are prompted for credentials at the start of your next obtool
session.
In the following example, login credentials are required for the first session, because the login token has expired. This first session is ended with an exit
command, and a second session is started. No login credentials are required for this second session, because the login token was preserved. The second session is ended with a logout
command, and a third session is started. The third session requires login credentials because the login token was destroyed by the logout
command.
[cfoch@stbcs06-1 ~]$ obtool Oracle Secure Backup 10.4.0.4.0 Warning: auto-login failed - login token has expired login: admin ob> exit [cfoch@stbcs06-1 ~]$ obtool ob> logout [cfoch@stbcs06-1 ~]$ obtool Oracle Secure Backup 10.4.0.4.0 login: admin ob>
You can force obtool to use different credentials when starting, destroying any existing login token. To do so, use the -u
option with obtool
, specifying the name of the user for the session. For example:
[root@osblin1 ~]# obtool -u admin Password: ob>
Note:
The practice of supplying a password in clear text on a command line or in a command script is not recommended by Oracle. It is a security vulnerability. The recommended procedure is to have the user be prompted for the password.
