CHAPTER 6
SAP ABAP and Java Stack Installation
In the last chapter we studied the planning and preparatory steps that have to be done in order
to perform a successful SAP system installation. In this chapter we will go into details of the
actual SAP installation steps, such as usage of SAP and database installation tools, verifying
the UNIX build before starting SAP installation tools, setting up the environment variables
before starting the actual install, starting the installation process, entering the parameters in
the SAP installation tool, executing the installation, troubleshooting any installation issues,
restarting the installation after troubleshooting the issue, and uninstalling the SAP software
when there is a need to delete a SAP system. In this chapter, one example of a SAP NW
ABAP stack installation (NW 7.0 ABAP System) and one example of a SAP NW 7.0 Java
stack installation (BI 7.0 Java System) will be covered in detail. In studying the installation
procedures, Oracle Database and UNIX operating systems are used for examples in this
chapter. Similar procedures can be used when installing SAP solutions in other operating sys-
tems and databases as well. In this chapter, practical aspects of performing an actual SAP in-
stallation are emphasized in detail, and a number of illustrations are included. The entire life-
cycle of an installation process will be discussed in this chapter.
SAP software can be shipped to a customer location to a designated person or it can be
downloaded to a central secure location at a customer data center from the SAP Portal (ht-
tp://service.sap.com/swdc) by a Basis administrator with high-level user authorization. Most
customers have moved to downloading the software on demand in recent years, because it is
convenient and easy to get the most current versions of the SAP software. Usually, the soft-
ware is downloaded to a shared network directory so that the same software inventory can be
used to build all the SAP systems of the organization. The downloaded software is in a
zipped format and needs to be unzipped before the installation media can be accessed.
Installation Tools
SAP media has the installation tools necessary to perform an SAP install. SAPinst and Oracle
Universal Installer are the main tools used to perform SAP and Oracle Database software in-
stallations. Oracle Database software should be installed ahead of the SAP software installa-
tion. This will allow Basis administrators to install SAP software using SAPinst without hav-
ing to install the Oracle Database software during the course of the SAP install. SAPinst will
create a new custom SAP database once the underlying Oracle Database software has been
installed. Please download the Oracle software from the SAP software download location and
not directly from the Oracle site. The reason is the SAP download location has the version of
