Managing Authorized OSB Accounts
Problem
You want to create and manage an operating system user account to perform backup and recovery tasks with OSB.

Solution
You can create the special OSB user and perform the necessary preauthorization during the OSB installation.
In this Solution, we'll show you how to handle user management after tse installation is complete by using obtool ,
the OSB command-line interface. Execute the obtool command mkuser to create the OSB user, as shown in the
following example:

ob> mkuser --class oracle --preauth prod1:+rman obuser

The previous command creates the account named obuser . Note the following about the mkuser command that
creates the new OSB user:
• obuser is the name of the new OSB user.
• class denotes that the new user obuser is assigned to the oracle class.

preauth option +rman preauthorizes sbt backups through RMAN. The prod1 here stands
for the host of the operating system user who has been granted preauthorized access to OSB.

• The

You've now successfully configured an RMAN preauthorization, wherein you authorized an operating system
user to make RMAN tape backups using OSB.
In addition to the mkuser command, obtool provides several other commands that help you manage OSB
accounts. The following examples show how to employ the most useful of these commands.

Listing Users
Use the lsuser command to list the names and attributes of one or more users. The simple lsuser command
provides the names of the users:

ob> lsuser

Use the lsuser command with the --long option to get a user's attributes, as shown here:

ob> lsuser --long salapati

Changing User Attributes
Use the chuser command to change an OSB user's attributes, as shown in the following example:

ob> chuser --password sammyy1 --email [e-mail]
