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.
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.
This section contains these topics:
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
/sysman/config directory and open the emoms.properties file in a text editor.
osb_enabled=true and save the file.
Stop and restart the Oracle Enterprise Manager Database Control console with the
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
Enter the password for the Oracle Secure Backup administrator in the Password field.
The Host Credentials page appears.
Enter the username and password of the operating system user on the administrative server. This user needs
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.

The Oracle Enterprise Manager console for a database provides a link to the Oracle Secure Backup Web tool. 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:
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:
For example, you might invoke the following URL:
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.
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:
Use this link to access online documentation for Oracle Secure Backup in PDF format.
Logs the current user out of the Oracle Secure Backup Web tool, clears user name and password cookies, and returns to the Login page.
Use this link to access settings for the following options:
Extended command output
This option displays obtool commands used to perform actions and generate output pages for the Oracle Secure Backup Web Tool at the bottom of each page.
This option sets the maximum idle time for
obtool background processes used by the Oracle Secure Backup Web tool to retain state information across requests.
Operations such as catalog browsing, data restore operations, and on-demand backup operations use a background
obtool process to retain state information across HTTP requests. When the time between requests exceeds this limit, the process exits gracefully and the associated user's session state is lost. The default is 24 hours.
Select table size
This option sets the number of rows in the display window of the Oracle Secure Backup Web tool interface. The default is 8 rows.
This link displays information about the Oracle Secure Backup software, including release date, system information, administrative server name, and IP address.
Click the Configure tab from the menu bar to display configuration options. Figure 4-3 shows an example of the Configure page.
The Configure page is divided into basic and advanced sections. The basic section contains the following links:
Click this link to configure one or more user accounts for logging into and employing Oracle Secure Backup.
Click this link to configure one or more hosts. A host is a computer that participates in the Oracle Secure Backup administrative domain.
Database Backup Storage Selectors
Click this link to configure one or more tape devices and media families for use during Oracle database backup and restore operations.
The advanced section contains the following links:
Click this link to create a job summary schedule for generation of job summaries for email distribution.
A job summary is a generated text file report that tells you whether a backup operation was successful. Oracle Secure Backup can generate and email job summaries detailing the status of each scheduled backup.
Defaults and Policies
Click this link to edit defaults and policies. Defaults and policies are sets of configuration data that control how Oracle Secure Backup runs throughout an administrative domain.
Click the Manage tab to display management options. Figure 4-4 shows an example of the Manage page.
The Manage page is divided into two main sections. One is for Maintenance, and the other is for Devices and Media. The Devices and Media section includes the following links:
Click this link to view and control libraries.
Click this link to reserve and unreserve tape devices for private use.
The Maintenance section includes the following links:
Click this link to manage jobs in an administrative domain. You can view the status of backup and restore jobs.
Click this link to filter and then view all volumes in the catalog. You can filter the results to scale down your search. A volume is a unit of media, such as 8mm tape. A volume can contain multiple backup images.
Click this link to manage backup images. A backup image is the work product of a single backup operation.
Click this link to view and remove backup sections. A backup section is that part of a backup image that occupies one physical volume.
Click this link to list and delete checkpoints describing certain in-progress, failed, and completed Network Data Management Protocol (NDMP) backups.
Click this link to manage daemons and control and view daemon properties.
The Backup page is divided into Operations and Settings sections. The Operations section contains the following link:
Click this link to perform one-time backups of data described by an existing dataset file.
The Settings section contains the following links:
Click this link to configure dataset files. A dataset file describes the data to back up.
Click this link to configure a backup schedule. The backup schedule describes the frequency with which a backup runs.
Click the Restore tab to display restore options. Figure 4-6 shows a sample page.
The Restore page has a single Operations section with the following links:
Click this link to browse data associated with backup and restore operations.
Directly from Media
Click this link to perform raw restores, which require prior knowledge of the names of the file-system objects you want to restore. You must also know the volume IDs and the file numbers on which the volumes are stored.
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 invoking
obtooland for more information on obtar, which is mostly used internally by
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
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 the
adminuser 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.
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:
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.
This command is a synonym for
This command ends the
obtool session and destroys the login token, so that you are prompted for credentials at the start of your next
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
[cfoch@stbcs06-1 ~]$ obtool Oracle Secure Backup 10.4.0.3.0 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 10.4.0.3.0 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.
