Set the Environment Variables on UNIX and Linux Systems

Before you can back up your database, you must set the following environment variables on UNIX and Linux systems:

• CASAP_HOME (to the path of the option)
• ORACLE_HOME

In addition, you must set the path to CASAP_HOME when you upgrade from a previous release of the option.

The following table describes the library path required for each operating system:

You can now submit a backup through SAPDBA or BR* Tools.

How to Configure User Accounts to Access SAPDBA and BR* Tools

SAPDBA and BR* Tools let you log in to SAP Oracle databases using any user account that is recognized by your computer's operating system. For example: oracle user, sap administrator, and so on.

To help ensure that the operating system account can perform SAP backup and restore operations using SAPDBA and BR* Tools, verify the following configurations:

• User Accounts--The user account must have privileges that allow it to access SAP Oracle databases while logged in to SAPDBA and BR* Tools.

  The following steps describe an example of how to configure this requirement on Oracle 10gr2 platforms:

  1. Verify that the Oracle user account is a member of the SAP Oracle installation group. The following screen describes how to allow user accounts to join a group named oinstall.

  

  1. Next, use the SQL*Plus utility to configure the operating system to authenticate the user.

     Obtain the value of the Oracle OS_AUTHENT_PREFIX initialization parameter as illustrated by the following screen:

  

  1. Create an Oracle user account using standard procedures. However, you must create the Oracle account by concatenating the value of OS_AUTHENT_PREFIX with the user.

     Example: ops$ + sapadmin = ops$sapadmin

  2. To verify that the user name does not exist, execute SQL*Plus using the following commands:

  

  1. If the account does not exist, create the account using the following SQL*Plus commands:

  

  1. After you create the account, verify that the account contains the DBA and CONNECT roles using the following SQL*Plus commands:

  

  1. If the Oracle user account does not contain these roles, grant the roles DBA and CONNECT to the account using the following SQL*Plus commands:

  

  1. Verify that the newly created account can access SAP Oracle databases. To do this, log in with newly created account and execute the following command:

  

• SAP BR* Tools--The SAP BR* Tools executables (for example, brbackup and brrestore) must have read and write privileges to the subfolder named sapbackup. sapbackup is located in the SAP Oracle data file folder when you log in using the operating system account.
