OSB Users and Classes
An OSB user is an account defined within an OSB administrative domain. These users are separate from OS users.
OSB user information is stored in the OSB administrative domain server. You are required to enter a username and
password when accessing OSB through its interfaces, such as
obtool
or Oracle Secure Backup web tool.
An OSB class is a set of privileges and rights granted to a user. Each user can be assigned to only one OSB class.
OSB classes help maintain a consistent user experience across all servers in an administrative domain.
OSB Daemons
OSB uses seven different background processes (daemons) to manage the configuration, backup, and restore
operations. The executables that start the daemons are in the
OSB_HOME/etc
directory on each of the servers. These
processes are as follows:
Schedule daemon (
obsheduled
) runs only on the admin server and manages the scheduled
backups.
Index daemon (
obixd
) runs only on the admin server and manages the backup catalog for
each client.
Apache web server daemon (
obhttpd
) runs only on the admin server and services the
Oracle Secure Backup web tool.
Service daemon (
observiced
) runs on the admin, media, and client servers. On the admin
server, it runs jobs as requested by the schedule daemon. When running on the media or
client server, it allows for remote administration of the host.
Network data management protocol (NDMP) daemon (
obndmpd
) runs on the admin,
media, and client servers. It provides data communication between servers in the
administrative domain.
Robot daemon (
obrobotd
) runs only on the media server and helps manage
communication to tape devices.
Proxy daemon (
obproxyd
) runs only on the client server and verifies user access for system
backup tape (SBT) backup and restore operations.
Now that you have a basic understanding of the OSB architecture, you are ready to download and install
theOSB software.
Download and Installation
You can download the OSB software from the Technology Network area of the Oracle web site
For the examples in this chapter, I downloaded OSB version 10.4.0.2.0 and saved the zip file
osb-10.4.0.2.0_linux32_cdrom120606.zip
under a staging directory
stage/osb
of my admin server in the OSB
administrative domain. You can stage this binary file in a location of your choice on your server.
