Redirecting a restore to a different client (SAP on Oracle databases only)

You have the option to restore an SAP database to a client other than the one that originally supplied the backup. This process to restore data to a different client is called a redirected restore.

Note:

In some situations, you can restore from lower to higher release levels of Oracle. For more information, see your Oracle documentation.

To perform a redirected restore, the following conditions must be present:

  • The source client and destination client must have identical computer system architectures, OS versions, and bit levels.

  • The source client and destination client must have identical Oracle RDBMS levels.

The redirected restore has the following process:

  • Configure the NetBackup server.

  • Copy files from the source client to the destination client.

  • Configure the NetBackup for SAP destination client.

  • Perform the redirected restore.

The following procedures explain each part of the process. For more information on redirected restores, see the NetBackup Administrator's Guide, Volume 1.

To configure the NetBackup server

  1. Verify that you are logged on as the NetBackup administrator.

  2. Configure the NetBackup server to allow redirected restores.

    • Allow restores from any client.

      Continue with step 3.

    • Allow restores from only selected clients.

      Continue with step 5.

  3. To allow any client to restore the backups of any other client, create the following file on the NetBackup master server:

    Windows:

    install_path\NetBackup\db\altnames\No.Restrictions

    UNIX or Linux:

    /usr/openv/netbackup/db/altnames/No.Restrictions
  4. Continue with step 7.
  5. To allow only the destination client to restore from all other clients, create the following file:

    Windows:

    install_path\NetBackup\db\altnames\client_name

    UNIX or Linux:

    /usr/openv/netbackup/db/altnames/client_name

    where client_name is the name of the destination client that is allowed to perform the redirected restore.

  6. If you performed step 5, and want to restrict the destination client to only restore from the source client, add the name of the NetBackup for SAP source client to the client_name file.
  7. On the destination client, back up the existing control files to preserve the original configuration.

    These files are usually in the $ORACLE_HOME/dbs (%ORACLE_HOME%\database) directory.

To configure the NetBackup for SAP destination client

  1. Change the client parameter on the destination client.

    Do one of the following:

    • Change the client parameter in the initSID.utl file on the destination client to the name of the source client.

    • Set the SAP_CLIENT environment variable on the destination client to the name of the source client. For example:

      SAP_CLIENT=source_client 
export SAP_CLIENT

    The SAP_CLIENT variable has higher priority than the value in the initSID.utl file.

  2. (Windows) On the destination client, create a file path like the one on the source client.

    For example:

    • Source client actual path is:

      C:\Oracle\SAP

    • Destination client actual path is:

      C:\Oracle\SAP
  3. (UNIX or Linux) Create a symbolic link on the destination client that resembles the actual path of the source client. Point it to the directory that points to the SAP files.

To copy the configuration and the control files (UNIX or Linux)

  • Copy configuration and control files from the NetBackup for SAP source client to the NetBackup for SAP destination client.

    • Copy the following files from the source client, usually $ORACLE_HOME/dbs, to the same location on the destination client:

      initSID.sap 
initSID.utl 
initSID.ora 
initSID.dba

    • Copy the $SAPDATA_HOME/sapbackup directory from the source client to the same location on the destination client.

To copy the configuration and the control files (Windows)

  • Copy configuration and control files from the NetBackup for SAP source client to the NetBackup for SAP destination client.

    • Copy the following files from the source client, usually %ORACLE_HOME%\database, to the same location on the destination client:

      initSID.sap 
initSID.utl 
initSID.ora 
initSID.dba

    • Copy the %SAPDATA_HOME%\sapbackup directory from the source client to the same location on the destination client.

To perform a NetBackup for SAP redirected restore

  1. Log onto the NetBackup for SAP destination client.
  2. Enter the following command:
    brrestore -d util_file -b last -m full

    Do not use the -m dest_dir option with brrestore. This option restores the files to the directory you specify, rather than to the original directories.
