Preparing to Install Oracle Secure Backup on Linux and UNIX

Perform the following actions before you begin:

Select hosts for the administrative server, media server and client roles, as described in "Planning Your Administrative Domain".
For Linux media servers, ensure that the SCSI Generic (SG) driver is installed. It is required for Oracle Secure Backup to interact with media devices.
If you are running setup or installob on a Linux host, then the compress and uncompress utilities must be installed on the system.
Determine the SCSI parameters for each tape drive and library attached to your Linux and UNIX media servers, as described in "Determining SCSI Device Parameters on Linux and UNIX". You can configure these devices as part of your initial installation process or later, but you need the information in any case.
Decide whether to perform an interactive or batch-mode installation.

In interactive mode, the installob program installs the software on one host at a time, prompting for the host name, roles, SCSI device information (for media servers), and any other required information for each installation. After each installation, you are asked whether you want to install Oracle Secure Backup on another host.

In batch mode, you must create or modify a network description file, which is a text file that describes your network configuration. The installob program uses the information in this file to perform a push installation, transferring the software across the network to the designated hosts and performing required installation and configuration steps.

Examine the sample network description file ./install/obndf for information on creating a network description file. The file contains extensive comments that document the required contents. If you plan to modify the file, then save a copy of the original.

Note:
The example in "Installing Oracle Secure Backup on Linux or UNIX with installob" describes installation in interactive mode.
Ensure that each host has a network connection and runs TCP/IP.

If using push installations, then configure destination hosts to allow rsh access for root from the administrative server without requiring a password. For more details on configuring rsh access for root without a password on your media servers and clients, refer to the operating system documentation for your platform.

If not using push installations, then decide how to make the installation media for Oracle Secure Backup available on each Linux or UNIX host in your administrative domain. For example, ensure that each host has a CD-ROM drive, or can mount a directory over NFS across the network containing the extracted archive of Oracle Secure Backup installation files.

Note:

Consider the security implications of configuring your hosts to permit rsh access for root without passwords when deciding whether to use remote installation.
If support for rsh access for root without passwords across your administrative domain is not part of your normal system configuration, then remember to disable it on each host in your administrative domain when the installation process is complete.

You must log in to each host with root privileges to perform the installation.
If you are installing Oracle Secure Backup in an Oracle Real Application Clusters (RAC) environment, then you must install Oracle Secure Backup on each node in the cluster.
