Information About Updating an Existing Database Instance 
You can perform an update of the SAP DB software for an existing SAP DB database instance with the
SDBUPD installation file. You can perform the update interactively or in the background, with the specification of the appropriate SDBUPD options. SDBUPD performs all necessary checks and selects the appropriate update strategy.
Prerequisites
To be able to perform an update of the desired database instance, the following prerequisites must be fulfilled:
- Only this one database instance is registered for the relevant SAP DB software installation.
- If other SAP DB software installations are present on your host, you must ensure that the database instances of these software installations are in the OFFLINE operational state, or stop the X Server with the command
dbmcli –d <database_name> -u <userid>,<password> x_server stop
The database instance must be in a status from which it can be restarted (that is, data and log areas have the required information, and the database parameters are set in such a way that the last start of the database instance ran successfully with these settings).
The system tables for the database instance have been loaded at least once.
