Background documentation Background Installation Locate the document in its SAP Library structure

You can perform an installation or upgrade of the SAP DB database software with SDBINST in the background, specifying the relevant SDBINST options.

Advantages of Installation in the Background

Performing an installation or an upgrade in the background takes less time.

You can use a call script to generate identical software installations on different computers.

Disadvantages of Installation in the Background

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 at this location, and an upgrade is possible for this version, an upgrade is performed. As a rule, an older package can be replaced by a new one.
On operating system platforms that support 32 bit and 64 bit applications, you can mix the software packages as desired (exception: SAP DB packages for Microsoft Windows 64 bit operating systems and the combination of Database Kernel and APO COM. These must always be either 32 bit or 64 bit applications.)
