This Readme document applies only to Oracle Secure Backup Release 10.1.0.2. This Readme documents licensing, supported platforms and devices as well as known and fixed issues.
For documentation, use your Web browser to access the Oracle Secure Backup documentation library. The library home page is named
index.htm and is located in the
doc directory of your CD-ROM image. You can also access the library online at the following URL:
The CD-ROM image for each platform contains all necessary tools, documentation, and software to install and operate Oracle Secure Backup on the selected platform.
Note:Each supported platform requires its own separate CD-ROM or installation Zip file. For example, if you are running an administrative domain using both Windows and Linux clients, you require separate installation media (CD-ROM or downloaded Zip file) for Windows and for Linux.
You can access the installation files from a physical CD-ROM or through a Zip file downloaded from the following product site:
The contents of the CD-ROM and Zip file for a given platform are identical.
The only product in this release is Oracle Secure Backup.
Refer to Oracle Secure Backup Licensing Information for licensing terms.
In an upgrade installation, the Oracle Secure Backup catalogs (contained in the
admin directory) are preserved retaining configuration information and backup metadata for your administrative domain. This state information for your administrative domain, such as the backup catalog, host, user and device configuration information, and any scheduled backup jobs, is stored in the
admin directory under the Oracle Secure Backup home on your administrative server.
Note:As with any upgrade, we recommend backing up the Administrative Server prior to upgrading.
Before upgrading an existing Oracle Secure Backup administrative domain to 10.1.0.2, you must shut down Oracle Secure Backup-related drivers and background processes on all hosts. Upgrade the administrative server, host first, and then the other hosts in the domain.
Brief instructions on each step are described in the following sections.
Before performing an upgrade installation, you must stop the Oracle Secure Backup-related daemons and services on all hosts in your administrative domain.
On Linux or Unix, use the
ps command to identify the Oracle Secure Backup daemon processes:
# /bin/ps -ef | grep ob
kill -9 command to stop each process.
On Windows hosts, you must stop the Oracle Secure Backup Services service, and, on media servers, disable the Oracle Secure Backup device driver.
To disable the driver, in Device Manger, under Tape Drives, right-click Oracle Secure Backup Device Driver, and select Disable. Then reboot the system.
To stop the Oracle Secure Backup Services service, open the Services applet, right-click the Oracle Secure Backup Services service, and select Stop.
To upgrade a Windows installation of Oracle Secure Backup, follow the Windows installation process described in Oracle Secure Backup Installation Guide.
Before the new version of Oracle Secure Backup can be installed, the previous version must be uninstalled. When the installer detects the existing install of Oracle Secure Backup, it runs the uninstaller program for the previous version automatically, before beginning the new installation.
Note:On a Windows administrative server, the uninstallation program displays the following prompt:
This system was configured as an Oracle Secure Backup Administrative Server. Oracle Secure Backup creates files specific to this administrative domain in the "admin" directory. Would you like to keep these files in case you reinstall Oracle Secure Backup? If you choose "Delete" all files related to Oracle Secure Backup will be removed from this system. If you choose "Keep" the files specific to this administrative domain will be retained.
Click Keep to retain the files in the
admin directory. The new installation of Oracle Secure Backup uses these files to keep the configuration of your administrative domain.
Complete the rest of the installation process as described in Oracle Secure Backup Installation Guide.
Note:Specify the same host roles for each host as were used in the previous installation.
To upgrade a Linux or Unix installation of Oracle Secure Backup, follow the setup and installation process described in Oracle Secure Backup Installation Guide.
During the upgrade process, the installer displays the following prompt:
Oracle Secure Backup is already installed on this machine (myhostname-sun2). Would you like to re-install it preserving current configuration data[no]?
yes to perform the upgrade installation, retaining your previous configuration.
The following sections describe outstanding bugs and known issues with Oracle Secure Backup.
On Windows Server 2003 and Windows 2000, on hosts that are only configured for the media server or client roles, the Oracle Secure Backup Services service is not started automatically after installation. You must start it manually.
This issue does not apply to Windows XP.
This issue does not apply to hosts configured for the administrative server role.
This issue only occurs immediately after the installation. The service is started automatically whenever Windows is rebooted.
To start the Oracle Secure Backup Services service, open the Services applet, right-click the Oracle Secure Backup Services service, and select Start.
On Windows administrative servers, if the title for a backup job contains upper case characters, email notification of the backup job summary fails.
On SUSE Linux, permissions for the Generic SCSI device files
/dev/sgp must be changed from 640 to 666 for Oracle Secure Backup to operate properly.
The Preferred Network Interface (PNI) capability supports bidirectional specification of communication between hosts. The PNI behavior is described below.
In cases where hosts have more than one network interface, you can specify which interface is used to transmit data to be backed up or restored between hosts by configuring Preferred Network Interface (PNI) settings for each host.
Configuring host A to specify a Preferred Network Interface on host B identifies the network interface on host B to use when host A and host B communicate.
When host A attempts to establish a connection with host B, the PNI settings on host A and host B are applied in the following manner:
Host A queries the administrative server for the PNI settings configured for host B, to see if a specific interface on host B should be used for transfers from host A. If an interface at host B is specified for communications with host A, then it is used for the transfer.
Host A also queries the administrative server for the PNI settings configured for host A, to see if a specific interface is preferred for transfers to host B. If an interface at host A is specified for communications with host B, then it is used for the transfer.
For example, suppose the host storabck10 has the following PNI setting configured:
ob> lspnistorabck10: PNI 1: interface: storabck10-rac clients: stacx53
When the host stacx53 connects to storabck10, it consults the configured PNI settings and determines that it must connect over the interface on storabck10 named storabck10-rac.
Now suppose that storabck10, acting as a client, wants to connect to a device connected to stacx53 (that is, stacx53 is now acting as a media server). storabck10 also references the PNI settings for both hosts, and discovers that it should use the local interface storabck10-rac in order to establish the connection with stacx53.
obtar command reports which interfaces are in use for a connection between
obtar and a remote backup device. To display this information in the
obtar transcript, use the
-J option on the
obtar command line, or as part of the
backupoptions policy. In the example above, the connection would be shown as:
09:38:38 A_O: sock 8 connects (local) storabck10.rac to (remote) stacx53
The following globalization restrictions apply to Oracle Secure Backup:
The Oracle Secure Backup Web Tool and command line interface are English-only, and are not globalized. Localizations or multi-byte character set data are not supported. All messages and documentation are in English.
Oracle Secure Backup does not support filenames or RMAN Backup names that are encoded in character sets that do not support null termination, such as Universal Character Set (UCS).
On a Linux host running Enterprise Manager Database Control or Enterprise Manager Grid Control, support for managing Oracle Secure Backup is not included until you apply the first Oracle Database 10g Release 2 patch set.
Also, in releases 10.2.0.1 and 10.2.0.2 of Enterprise Manager Grid Control and release 10.2.0.2 of Enterprise Manager Database Control, the Oracle Secure Backup section of the Maintenance page is not displayed by default.
Follow the steps in the section "Using Enterprise Manager" in the "Getting Started" chapter of Oracle Secure Backup Administrator's Guide to configure Enterprise Manager to include the Oracle Secure Backup section in the Maintenance page.
The clocks on the administrative server, clients and media servers must be synchronized to within 60 minutes of each other. If the time skew among hosts in the administrative domain is more that 60 minutes, then you may encounter problems when attempting to issue the
mkhost command to configure new hosts. The error that appears in the
observiced log file on the client or media server is "
failed to validate certificate".
The solution is to synchronize the clock on all hosts in the administrative domain to match the clock on the administrative server, and then retry the failed operation.
You cannot edit the
RMAN-DEFAULT media family when using Enterprise Manager.
Use the Oracle Secure Backup Web tool or
obtool to edit the
RMAN-DEFAULT media family.
Configuring a Linux host for the Oracle Secure Backup media server role requires that the SCSI Generic driver be installed on that host. The host must also be configured to automatically reload the driver after a reboot.
Kernel modules are usually loaded directly by the facility that requires them, if the correct settings are present in the
/etc/modprobe.conf file. However, it is sometimes necessary to explicitly force the loading of a module at boot time.
For example, on RedHat Enterprise Linux, the module for the SCSI Generic driver is named
sg. Red Hat Enterprise Linux checks for the existence of the
/etc/rc.modules file at boot time, which contains various commands to load modules.
rc.modulesshould be used, and not
rc.modulesis executed earlier in the boot process.
The following commands can be used to add the
sg module to the list of modules configured to load as
root at boot time:
# echo modprobe sg >> /etc/rc.modules # chmod +x /etc/rc.modules
On Windows platforms, when the
securecomms security policy is enabled (the default setting), you must be logged in as Administrator (or your logged-in account must belong to the Administrators group) in order to run the Oracle Secure Backup
obtool command line tool.
If you configure the media server role on a Windows 2000 host with no attached media devices, then the operating system will continuously try to load the Oracle Secure Backup driver. Continuously trying to load the driver uses most of the available CPU cycles on that system, and renders the system unusable.
Microsoft has provided a hotfix which should be applied to any Windows 2000 host configured for the media server role. For a description of the Windows 2000 issue that causes this problem and the hotfix that resolves it, refer to the following URL:
To avoid this issue, when there are no media devices attached to a Windows 2000 host, do not configure that host for the media server role.
The default configuration of the Windows Firewall in Windows XP can block ports used by Windows hosts running Oracle Secure Backup. This can prevent Windows hosts from connecting to other hosts in the administrative domain.
Instructions for configuring the Windows Firewall to not interfere with Oracle Secure Backup are contained in the Oracle Secure Backup Installation Guide.
When uninstalling Oracle Secure Backup on a Windows administrative server, the uninstaller allows you to click Keep, to keep files containing the record of your administrative domain and backups for use by a future installation of Oracle Secure Backup, or Delete, to delete these files and create a new administrative domain in a future installation.
However, the release 10.1.0.1 uninstaller does not correctly preserve these files. Running the installer from release 10.1.0.1 deletes the administrative domain configuration, even if you choose Keep.
To upgrade an installation of release 10.1.0.1 and preserve the configuration of the administrative domain, run the installation program for release 10.1.0.2. Do not uninstall release 10.1.0.1 first. The installer for 10.1.0.2 upgrades an existing installation of release 10.1.0.1 transparently, and preserves the administrative domain configuration.
If you run the installer for Oracle Secure Backup release 10.1.0.2 on Windows on a system with release 10.1.0.2 already installed, the installer displays the Modify, Repair and Remove options. Only the Remove option is correctly supported in release 10.1.0.2. Do not use the Modify or Repair options in the installer when installing in place over an existing 10.1.0.2 installation.
When upgrading an existing Windows 64-bit installation of Oracle Secure Backup release 10.1.0.0.0 to release 10.1.0.2, you must uninstall release 10.1.0.0.0 before you can run the installer for release 10.1.0.2.
However, the Microsoft Installer reports an internal error, if the file
%WINDIR%\system32\orasbt.dll is present when you run the Windows installer for Oracle Secure Backup release 10.1.0.2. Therefore, delete this file manually before running the installer for Oracle Secure Backup release 10.1.0.2.
The following bugs have been addressed in Oracle Secure Backup Release 10.1.0.2:
Very Long Volume IDs Became Corrupted
When a volume ID of 25 or more characters is used, the last six characters are required to be numeric. Previous versions of Oracle Secure Backup did not correctly enforce this requirement and generated Volume IDs that did not end with numeric characters.
Oracle Secure Backup now replaces the last six characters of long volume IDs with numeric characters.
"Device Already Opened By This Process" Error
When testing whether a locally attached tape device was already in use, Oracle Secure Backup compared the SCSI channel, SCSI ID and SCSI LUN but did not compare the addresses of the SCSI adapters. This meant that a process could not simultaneously open two tape devices whose addresses differed only on adapter address. As a result, backups or other operations failed with a "Device already opened by this process" error if two media devices on different SCSI adapters had the same SCSI channel, SCSI ID and SCSI LUN values.
Windows 2000 Client Host Database Backup Fails with Repeated Warning "unsupported message 0.0 received"
A database backup from a Windows 2000 client could fail with repeated error messages sent to RMAN. The communication between RMAN and the Windows 2000 client was handled incorrectly, and caused repeated zero-length messages to be sent. In this case, the
RMAN database backups no longer fail in this manner.
"Page Not Found" Errors in Web Tool After Login
Selecting a user password that was a multiple of eight characters long would make the Web tool inaccessible.
Can Only Use Lower-Case Letters in Host Names on Windows Administrative Servers
Windows administrative servers now support upper-case letters in host names.
Tape Device Debug Logging Can Cause Backup Failures
Restriction on enabling tape device-related debug logging has been removed.
RMAN Backup Failed with RMAN-00600 Error
An RMAN database backup could fail when a file system backup job was started by the scheduler during a long-running backup job. This failure no longer occurs.
Restriction on Number of Hosts and Tape Drives with Windows Administrative Servers
The previous limitation on the maximum number of hosts and tape drives supported when using a Windows host as administrative server has been removed.
Restart Windows Media Servers and Clients When Changing Policy Parameters
It is no longer necessary to restart Windows media servers when changing policy parameters.
Database Backup Jobs Fail If Tape Device Becomes Temporarily Unavailable During Backup
If the device becomes available again within the user-configured RMAN resource wait time, then the database backup job will now continue when the tape device becomes available again.
Backup of Oracle Sparse Files Fails if Exclude Oracle Files Option is Specified
The backup of a database sparse file of size greater than 2GB now succeeds on Linux when the backup excludes database temporary files.
Device Restrictions Cannot Be Removed Via Web Browser
Web tool can now remove device restrictions
Obtool LSBU Command Not Handling '\' in Path
Obtool now supports the backslash character
Administrative Server Role Not Supported on Non-English Windows Installations
Oracle Secure Backup can now be successfully configured as an administrative server on supported non-English versions of Windows. Previous limitations have been removed.
