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 (Selection of the Upgrade Strategy).
This procedure is currently valid only for the instance type liveCache 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 7.5.00 or higher, and on which operating system you work.
If you work on 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 the 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 the X Server is running. In this case, you no longer need to stop the X Server and the database instances.
If you work on Microsoft Windows, you must always stop the X Server and all database instances.
· You have backed up the liveCache transactions to the APO database.

...
1. If necessary, stop each database instance with the following command:
dbmcli –d <database_name> -u <dbm_user>, <password> db_offline
2. If necessary, stop the X Server.
x_server stop
3. Start the SDBUPD program with the following command:
UNIX, Linux: |
Microsoft Windows: |
./SDBUPD –d
<database_name> -u <dbm_user>,<password> |
sdbupd –d <database_name> -u <dbm_user>,<password> |
You only need to specify the special operating system user <sdb_user> and the group <sdba_group> (according to the Authorization Concept for UNIX Operating Systems) if you are upgrading to software version 7.5.00.
4. SDBUPD performs the upgrade, and displays a success message if completed successfully. You are prompted to start liveCache.
5.
Start
liveCache (Starting
liveCache).
6. Recover the data from the APO system to liveCache (see the above link to Upgrade for SAP SCM 4.1: SAP liveCache 7.5.).
The specified liveCache database instance in the SAP APO system and its software have been upgraded.
liveCache is in the operational state ONLINE.
