You use the program SDBUPD to upgrade the database instance. First you make a complete data backup for the database instance that you want to upgrade. Then you use the SDBUPD program to substitute the software.
You use this upgrade strategy if your database instance is part of an SAP system. This strategy is currently valid only for the instance type liveCache in the SAP APO system, when you are changing the version of the database software without changing the APO release (Selection of the Upgrade Strategy).
It is valid for all supported operating system platforms.
There can not be any remote communication between the database instances and applications during the upgrade, since the X Server software may need to be substituted, depending on the source and target version of the upgrade. Therefore, stop all database instances, so that SDBUPD can stop any X Servers that are still running. Alternatively, you can stop the X Server program yourself, before the upgrade.
· You have stopped all database instances, or, alternatively, the X Server program ( Xserver service).
· The database parameters of the database instance you want to upgrade have not changed since the last restart.
· You have made a complete data backup in the operational state COLD (up to Version 7.3) or ADMIN (from Version 7.4), and have not transferred the database instance to the operational state ONLINE.
...
1. 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 <sapdb_user>, the administrator group <sapdb_admin>, and the support group <sapdb_support> (according to the Authorization Concept for UNIX Operating Systems) if you are upgrading to software version 7.4.04.
SDBUPD updates the software. You see a message about the successful installation of the software, and you are prompted to recover the database instance from the backup.
2. Log on to the Database Manager CLI with the data from the database instance that you want to recover, and start the database instance recovery.
3.
Exit the
Database Manager CLI with the command
exit | release | quit |
bye.
4. Restart 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> |
SDBUPD loads the system tables, and displays a success message if completed successfully. It then flags the installation as complete.
5.
Now start
liveCache, so that the system can update it (Starting
liveCache).
The specified liveCache database instance in the SAP APO system and its software have been upgraded.
liveCache is in the operational state ONLINE.
