CHAPTER 19
Database Installation and Configuration
In this section we will cover different aspects of database management in SAP systems.
Several relational database management systems are fully supported by SAP applications,
and in this chapter we will use Oracle Database as an example to cover the database manage-
ment concepts and tools provided by SAP to support the application install and maintenance.
We will cover Oracle Database architecture and internals, database installation and configura-
tion, and database patch application. In subsequent chapters we will cover the SAP
BRTOOLS for administering the Oracle Database and database backup and restore concepts,
tools, and procedures.
Oracle Database Internal Architecture
Oracle Database internals consist of two main components: the database and the Oracle in-
stance. The database is the static part of the Oracle system, and the Oracle instance is the
memory structures and the Oracle background processes that are started when the database is
started. The Oracle Database internal architecture is shown in
Figure 19-1
