Refer to Oracle Secure Backup Licensing Information for licensing terms.
If you are upgrading an existing Oracle Secure Backup release 10.1 installation to release 10.2.0.5, then you must upgrade every host in the Oracle Secure Backup administrative domain. Oracle Secure Backup release 10.2 is incompatible with Oracle Secure Backup release 10.1.
If you are upgrading an existing Oracle Secure Backup release 10.2.0.1, 10.2.0.2, or 10.2.0.3 installation to Oracle Secure Backup release 10.2.0.5, then you must upgrade the administrative server and media server hosts in the Oracle Secure Backup administrative domain. Oracle recommends that you also update your clients in the domain to Oracle Secure Backup release 10.2.0.5. But hosts acting as clients only can remain at Oracle Secure Backup release 10.2.0.1, 10.2.0.2, or 10.2.0.3 and participate as part of an Oracle Secure Backup release 10.2.0.5 domain.
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:
Oracle recommends backing up the administrative server before upgrading.Before upgrading an existing administrative domain to Oracle Secure Backup release 10.2.0.5, you must shut down drivers and background processes related to Oracle Secure Backup 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 daemons and services related to Oracle Secure Backup on all hosts in your administrative domain. The preferred methods for stopping the Oracle Secure Backup daemons are as follows.
On Linux:
# /etc/init.d/observiced stop
On Solaris:
#/etc/init.d/OracleSecureBackup stop
On both Linux and Solaris administrative servers, it is also necessary to stop the Oracle Secure Backup Web tool processes. Use the ps
command to identify the Oracle Secure Backup httpd daemon processes:
# /bin/ps -ef | grep ob
Use the kill -9
command to stop each process.
On Windows hosts, you must stop the Oracle Secure Backup Services service:
Open the Services applet.
Right-click the Oracle Secure Backup Services service, and select Stop.
You can upgrade your Windows 32-bit administrative server, media servers, and clients from Oracle Secure Backup release 10.2.0.1, 10.2.0.2, or 10.2.0.3 to Oracle Secure Backup release 10.2.0.5 simply by running the Oracle Secure Backup release 10.2.0.5 installer. This is called an upgrade installation. The installer detects the existing installation of Oracle Secure Backup and runs the uninstaller for the previous version automatically before beginning the new installation.
When you upgrade your administrative server from Oracle Secure Backup release 10.2.0.1, 10.2.0.2, or 10.2.0.3 to Oracle Secure Backup release 10.2.0.5, the uninstaller will display 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.
You must choose the Keep option for the admin directory files. Selecting the Delete option will cause the installation to be incomplete, and then you must uninstall and reinstall Oracle Secure Backup to complete the installation. If you do not want to save the existing admin directory files, then you must exit the installation, uninstall Oracle Secure Backup release 10.2.0.1, 10.2.0.2, or 10.2.0.3, and select the Delete option. After you have uninstalled Oracle Secure Backup release 10.2.0.1, 10.2.0.2, or 10.2.0.3, you can install Oracle Secure Backup release 10.2.0.5 by running the Oracle Secure Backup release 10.2.0.5 installer.
You can upgrade your Windows 32-bit administrative server and clients from Oracle Secure Backup release 10.1 to Oracle Secure Backup 10.2.0.5 with an upgrade installation, so long as the administrative server is not also a media server.
When you upgrade your administrative server from Oracle Secure Backup release 10.1 to Oracle Secure Backup release 10.2.0.5, you should select the Keep option to keep the existing configuration of your administrative domain. If you select the Delete option, then the Oracle Secure Backup release 10.2.0.5 installation will succeed, but you will have to re-enter all of your Oracle Secure Backup configuration settings.
An upgrade installation will not successfully upgrade a media server or an administrative server that is also a media server from Oracle Secure Backup release 10.1 to Oracle Secure Backup release 10.2.0.5. In this special case, you can use the following procedure:
Uninstall the existing Oracle Secure Backup software.
You can uninstall the existing Oracle Secure Backup software by selecting Start > Programs > Oracle Secure Backup > Uninstall Oracle Secure Backup.
Select the Keep option if you are upgrading an administrative server that is also a media server.
Restart the host.
Run the Oracle Secure Backup release 10.2.0.5 installer.
Different upgrade installation procedures must be used for Windows x64 than those described in "Upgrade Installation of Oracle Secure Backup Release 10.2.0.5 on Windows 32-Bit". You can use the following procedure to upgrade a Windows x64 administrative server or client, so long as the administrative server is not also a media server:
Uninstall the existing Oracle Secure Backup software, selecting the Keep option if you are upgrading an administrative server.
See Also:
"Upgrade Installation of Oracle Secure Backup Release 10.2.0.5 on Windows 32-Bit" for more information on uninstalling Oracle Secure Backup software and the Keep optionRun the Oracle Secure Backup release 10.2.0.5 installer.
You can use the following procedure to upgrade a Windows x64 media server or administrative server that is also a media server:
Uninstall the existing Oracle Secure Backup software, selecting the Keep option if you are upgrading an administrative server that is also a media server.
Restart the host.
Run the Oracle Secure Backup release 10.2.0.5 installer.
To upgrade a Linux or UNIX installation of Oracle Secure Backup, follow the setup and installation process described in Oracle Secure Backup Installation and Configuration 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]?
Enter yes
to perform the upgrade installation, retaining your previous configuration.
Oracle Secure Backup release 10.2.0.5 supports the administrative server, media server, and client roles on AIX platforms. The previous version of Oracle Secure Backup must be uninstalled before installing Oracle Secure Backup 10.2.0.5.
Note:
Oracle Secure Backup Installation and Configuration Guide states that AIX support is limited to the client role. This statement is no longer correct.During Oracle Secure Backup installation, the Oracle Secure Backup admin
user is mapped by default to UNIX user root
and UNIX group root
. In this configuration, Oracle Secure Backup requires that the user root
be a member of the group root
to back up the file system successfully. AIX does not define a group root
by default. If the group root
does not exist on your AIX system, then you must create it and make user root
a member of it.
Note:
This mapping of the Oracle Secure Backupadmin
user can be changed post-installation.In order to access SCSI or Fibre Channel tape devices, Oracle Secure Backup requires the following identifying information about how the devices are attached to their hosts:
SCSI bus name
Target ID
Logical Unit Number (LUN)
This information might not be readily available for all attached devices using standard operating system commands. To assist with gathering device information in AIX environments, Oracle Secure Backup includes the standalone tool obscan
. The obscan
executable is in the cdtools directory of the Oracle Secure Backup CD or CD image.
Note:
The information obtained fromobscan
is required when running the Oracle Secure Backup makedev
command. See "Creating Device Special Files with makedev" in the Oracle Secure Backup Installation and Configuration Guide for more information.You must have operating system privilege to access devices, which is often root access, to run obscan
. The syntax for obscan
is as follows, where device_filename
is the device file name of the SCSI bus or Fibre Channel fabric to scan:
obscan device_filename
Run obscan
for each SCSI and Fibre Channel adapter with tape devices to be used by Oracle Secure Backup. In the following example, obscan
gathers information about the tape devices connected to the SCSI bus identified by the device file /dev/scsi2:
obscan /dev/scsi2 obscan version 10.2.0.3 (AIX) Copyright (c) 2008, Oracle. All rights reserved. DEVICE information for /dev/scsi2 Target-id : 0, Lun : 0 Vendor : ADIC Product : FastStor 2 Target-id : 5, Lun : 0 Vendor : HP Product : Ultrium 2-SCSI Total count of Media Changers and/or Tape devices found : 2
In this second example, obscan
gathers information about the tape devices connected to the Fibre Channel fabric identified by /dev/fssci0:
obscan /dev/fscsi0DEVICE information for /dev/fscsi0 Target-id : 6423827, Lun : 0 Vendor : ADIC Product : Scalar 24 World Wide Name : 2001006045175222 Target-id : 6423827, Lun : 1 Vendor : IBM Product : ULTRIUM-TD2 World Wide Name : 2001006045175222 Target-id : 6423827, Lun : 2 Vendor : IBM Product : ULTRIUM-TD2 World Wide Name : 2001006045175222 Target-id : 6491411, Lun : 0 Vendor : ADIC Product : Scalar i500 World Wide Name : 2400005084800672 Target-id : 6491411, Lun : 1 Vendor : IBM Product : ULTRIUM-TD3 World Wide Name : 2400005084800672 Target-id : 6491411, Lun : 2 Vendor : IBM Product : ULTRIUM-TD3 World Wide Name : 2400005084800672 Target-id : 6491411, Lun : 3 Vendor : IBM Product : ULTRIUM-TD3 World Wide Name : 2400005084800672 Target-id : 6491411, Lun : 4 Vendor : IBM Product : ULTRIUM-TD3 World Wide Name : 2400005084800672 Total count of Media Changers and/or Tape devices found : 8
Using the information from the obscan
tool, you can create attach points used within Oracle Secure Backup to identify devices for backup and restore operations. In the following example the attach point /dev/obl8 is created for the ADIC FastStor 2 library attached to scsi2 having the target id 0 and lun 0:
makedev Enter logical unit number 0-31 [0]: 8 Enter 'd' if this device is a tape drive or 'l' if a SCSI-2 addressable tape library [d]: l Enter SCSI bus name: scsi2 Enter SCSI target id 0-16777215: 0 Enter SCSI logica l unit number (lun) 0-7 [0]: 0 /dev/obt8 created
In this second example the attach point /dev/obl9 is created for the ADIC Scalar 24 library attached to fsci0 having the target id 6423827 and lun 0:
makedev Enter logical unit number 0-31 [0]: 9 Enter 'd' if this device is a tape drive or 'l' if a SCSI-2 addressable tape library [d]: l Enter SCSI bus name: fscsi0 Enter SCSI target id 0-16777215: 6423827 Enter SCSI logical unit number (lun) 0-7 [0]: 0 /dev/obl9 created
Note:
Theobscan
tool is not included as part of the Oracle Secure Backup installation. It is provided as an optional tool for device identification in AIX environments.Supported platforms, web browsers and NAS devices are listed on Certify on Metalink, at the following URL:
Tape drive and library matrixes are available at the following URL:
This section discusses Oracle Secure Backup release 10.2.0.5 outstanding bugs and known issues.
Oracle Secure Backup supports the use of Fibre Channel-attached tape devices on media servers running Solaris 10. The Oracle Secure Backup install script and makedev utility cannot be used to create the needed links in the /dev directory to the device special files for such devices.
The Solaris sgen
driver must be disabled before installing Oracle Secure Backup. If it is not disabled, then it might attach to your media changer or tape devices and prevent Oracle Secure Backup from attaching to them.
To disable the Solaris sgen
driver:
Comment out all entries in /kernel/drv/sgen.conf.
Check the /etc/driver_aliases file for any sgen
entries and remove them using the update_drv
command. Suppose, for example, that /etc/driver_aliases contains the following entries:
sgen "scsa,08.bfcp" sgen "scsc,08.bvhci"
To remove these entries you would run the following commands:
/usr/sbin/update_drv -d -i '"scsa,08.bfcp'" sgen /usr/sbin/update_drv -d -i '"scsa,08.bvhci'" sgen
Restart your system to release the tape devices.
During installation, the Oracle Secure Backup driver automatically identifies Fibre Channel-attached devices by their World Wide Names. After installing the driver, you must determine the World Wide Name for each device, and then manually create symbolic links in the /dev directory that point to the actual attach points for the devices.
To create device special files for Solaris 10 tape devices:
Run the Oracle Secure Backup install script on your media server.
When the Oracle Secure Backup driver is installed, the install script prompts:
NOTE: The Oracle Secure Backup device driver has been successfully installed. Would you like to configure (or reconfigure) any Oracle Secure Backup devices that are attached to dlsun1976 [no]?
Enter no
.
After install completes, run the dmesg
command and examine the output.
The Oracle Secure Backup driver adds messages to the log that contain the World Wide Names for the Fibre Channel-attached tape devices. The attach points for tape drives contain the string sgen
. The attach points for tape libraries contain the string st
.
For example, the following output contains the World Wide Names and corresponding attach points for a tape drive and a tape library:
Dec 12 17:12:53 storabck22 scsi: [ID 799468 kern.info] ob30 at fp0: name w500308c162680e24,1, bus address 6119e8 Dec 12 17:12:53 storabck22 genunix: [ID 936769 kern.info] ob30 is /pci@1f,4000/fibre-channel@2/fp@0,0/sgen@w500308c162680e24,1 Dec 12 17:12:53 storabck22 scsi: [ID 799468 kern.info] ob31 at fp0: name w500308c162680e24,0, bus address 6119e8 Dec 12 17:12:53 storabck22 genunix: [ID 936769 kern.info] ob31 is /pci@1f,4000/fibre-channel@2/fp@0,0/st@w500308c162680e24,0
For each device listed in the dmesg
output, assign an Oracle Secure Backup logical unit number.
Create symbolic links in the /dev directory that reference the attach points.
The name for the symbolic link should be /dev/obt
n
for tape drives and /dev/obl
n
for tape libraries, where n
is the Oracle Secure Backup logical unit number you assigned to the device in step 3.
For example, assume that you assign the devices listed in the output of step 2 the Oracle Secure Backup logical unit number 0. The resulting device names are /dev/obl0
for the tape library, and /dev/obt0
for the tape drive. The following commands create the required symbolic links in /dev:
ln –s /devices/pci@1f,4000/fibre-channel@2/fp@0,0/sgen@w500308c162680e24,1:fp0 /dev/obl0 ln –s /devices/pci@1f,4000/fibre-channel@2/fp@0,0/st@w500308c162680e24,0:fp0 /dev/obt0
Use the mkdev
command in obtool or the Oracle Secure Backup Web tool to add these devices to your administrative domain.
Volumes created within one Oracle Secure Backup domain can be imported into an alternate Oracle Secure Backup domain. Best practice recommendation is to use a different Volume ID naming scheme for each domain to avoid duplicate Volume IDs when volumes are imported into an alternate Oracle Secure Backup domain (catalog). With the same Volume ID naming scheme in multiple domains, importing volume metadata between domains could potentially be problematic, allowing multiple volumes with the same Volume ID maintained within one domain.
Associated with Bug 6631412.
You must restore the NDMP media server user name and password after upgrading to Oracle Secure Backup release 10.2.0.5. You can use the obtool chhost
command:
# chhost –ndmppass <ndmp-password> --ndmpuser <ndmp-username> <host-name>
Associated with Bug 6893306.
The encryption algorithm displayed in the Oracle Secure Backup Web tool Configure: Hosts page is incorrect. You must use the obtool lsh
command to display the correct setting:
# lsh –l <host-name>
Associated with Bug 6894525.
You cannot change the encryption algorithm for a host on the Oracle Secure Backup Web tool Configure: Hosts page. You must use the obtool chhost
command:
# chhost –algorithm <algorithm-type> <host-name>
Associated with Bug 6894525.
The TCP/IP buffer size displayed on the Oracle Secure Backup Web tool Configure: Hosts page is blank when the buffer size is set to the default. You must use the obtool lsh command:
# lsh –l <host-name>
Associated with Bug 6911984.
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 Oracle Enterprise Manager Database Control or Oracle 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 Oracle Enterprise Manager Grid Control releases 10.2.0.1 and 10.2.0.2 and Oracle Enterprise Manager Database Control release 10.2.0.2, the Oracle Secure Backup section of the Maintenance page is not displayed by default.
Follow the steps in "Enabling Oracle Secure Backup Links in Oracle Enterprise Manager" in Chapter 4 of Oracle Secure Backup Installation and Configuration Guide to configure Oracle Enterprise Manager to include the Oracle Secure Backup section in the Maintenance page.
Note:
The Oracle Secure Backup section of the Maintenance page might not appear in Oracle Database Control, even after enabling display of Enterprise Manager links using the procedure described in Oracle Secure Backup Installation and Configuration Guide. The resolution for this problem is described in Metalink note 399826.1.Oracle Secure Backup release 10.2.0.5 for Windows x64 installation cannot upgrade an existing Oracle Secure Backup release 10.1.0.2 installation. The upgrade will fail and cause the Install Wizard to be interrupted. The failure will not modify the current Oracle Secure Backup installation. You must first uninstall the current Oracle Secure Backup installation before installing Oracle Secure Backup release 10.2.0.5.
Steps 4 and 5 of the Catalog Recovery Procedure in the Oracle Secure Backup Administrator's Guide are different for the Windows platform. All other steps in the recovery procedure should be followed.
Step 4 for Windows is the following:
Load your OSB-CATALOG-MF
backup volume into the drive and verify the volume and file number by indexing the tape using the obtar -tf drive_name -F file_number
command as shown in the following example:
C:\>obtar -tf t4_d1 -F 1 > outt C:\>more outt C:\osb\backup\admin ... C:\osb\backup\db ...
Step 5 for Windows is the following:
Extract the backup directory to an alternate location using the obtar -xf drive_name -F file_number -s,P,R,
(Replace prefix P with string R) command.
Note, the path substitution syntax for obtar
is "-s,P,R,
(Replace prefix P with string R)."
You absolutely must restore the catalog backup to an alternate directory. Restoring the catalog backup to its original location leaves Oracle Secure Backup configuration in an inconsistent state.
C:\>obtar -xf t4_d1 -F 1 -s,C:/osb/backup,C:/osb/backup-restored, C:\osb\backup-restored>dir *. <DIR> admin <DIR> db
