You use the program SDBUPD to upgrade the database instance. This substitutes the SAP DB software only.
You can use this procedure if only the build number of the version has changed between the source and target version, and also for upgrades from 7.4.03 to 7.4.04 (see also Selection of the Upgrade Strategy).
You use this upgrade strategy if your database instance is part of an SAP system.
You can use this procedure even if the database instance is not combined with an SAP system. To do this, however, the following prerequisites must be fulfilled:
· The program SDBINST was used to install the existing software (that is, with a tgz package or a zip file, and not an rpm package)
· Each database instance refers to a separate software installation.
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.
Before you start upgrading a database instance, make sure that you have up-to-date log backups and/or data backups for recovering this database instance in the event of errors.
The database parameters of the database instance you want to upgrade must not have been changed since the last restart.
· The database instance that you want to upgrade is the only instance that refers to the installation path of the software you want to update.
· The database instances is in one of the three defined operational states, which means that there are no errors.
· You have stopped all database instances, or, alternatively, the X Server program.

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 performs the upgrade, and displays a success message if the upgrade is completed successfully. It then flags the installation as complete.
The database instance and its software have been upgraded.
If you have upgraded a liveCache database instance, it is now in the operational state OFFLINE.
If you have upgraded a SAP DB OLTP database instance, it is now in the operational state ONLINE.
