You can perform an installation or upgrade of the SAP DB database software with
SDBINST in the background. You can use the appropriate SDBINST options to define the necessary parameters.Advantages
Performing an installation or an upgrade in the background takes less time.
You can use call script to generate identical software installations on different computers.
Disadvantages
You must enter all the required options in the call script correctly and completely. Some options are only determined from the software packages at runtime. As a result, it is not possible to check whether the option list is complete at the start of an installation. This means that the system will terminate installation if it needs an option that is missing.
Installation or upgrade
During background installation, the installation program SDBINST itself decides whether it is dealing with a new installation or an upgrade. If the relevant
software package already exists in the location in question, an upgrade is carried out, providing it is allowed for the version. As a rule, an older package can be replaced by a new one. The software packages can be combined as required on operating system platforms that support 32 and 64 bit applications.Procedure
