## Upgrading with APO Extract/Load

### Use

You use the SDBUPD program for an upgrade with APO Extract/Load. You must first back up the transaction data of the application system from the liveCache database instance to the APO database, and then substitute the software (Selecting an Upgrade Strategy).

This procedure is currently valid only for the liveCache instance type in the SAP APO system. It is valid for all operating system platforms supported by the database system.

The procedure depends on whether your source version is lower than 7.5.00, or is 7.5.00 or higher, and on your operating system.

If your operating system is UNIX or Linux and your source version is lower than 7.5.00, then you must stop the X Server and all database instances before the upgrade. Remember that this interrupts communication between the clients and all local database instances. If your source version is 7.5.00 or higher, then the X Server software supports an update of the database software while X Server is running. In this case, you no longer need to stop the X Server and the database instances.

If you are working on Microsoft Windows, you must always stop the X Server and all database instances.

### Prerequisites

● You need to have backed up the liveCache transactions to the APO database.

For more information, see the SAP Service Marketplace under service.sap.com/upgradeNW2004s

● The database parameters of the database instance that you want to upgrade must not have changed since the last restart.

● The database instance may be in any operational state.

### Procedure

...

1. If necessary, stop each database instance with the following command one by one:

>dbmcli –d <database_name> -u <dbm_operator>,<dbm_operator_password> db_offline

2. If necessary, stop every individual scheduler:

>dbmcli –d <database_name> -u <dbm_operator>,<dbm_operator_password> scheduler_stop

3. If necessary, stop the X Server:

>x_server stop

4. Start the SDBUPD program with the following command one by one:

UNIX, Linux: | Microsoft Windows:
>./SDBUPD –d <database_name> -u <dbm_operator>,<dbm_operator_password> [-o <sapdb_user> -g <sapdb_admin>] | >sdbupd –d <database_name> -u <dbm_operator>,<dbm_operator_password>

You only need to specify the <sdb_user>special operating system user and the <sdba_group> group if you are performing an upgrade for a software version lower than 7.5.00 (see Concepts of the Database System, Special Operating System Users and Groups UNIX/Linux)).

5. SDBUPD performs the upgrade, and displays a message to indicate that it has been completed successfully. You are prompted to start liveCache.

6. Start the liveCache (Starting liveCache).

7. Restore the data from the APO system to liveCache.

### Result

The specified liveCache database instance in the SAP APO system and its software have been upgraded.

The liveCache is now in the ONLINE operational state.
