In this chapter, we will describe how to install the RDBMS software using the Oracle Universal Installer and the database management tools using the Database Configuration Assistant (DBCA). An important thing to bear in mind when reading this chapter is that the RDBMS software installed for a RAC database home is identical to the installation for a single-instance database home, with one exception: it must have the software for the RAC option linked in. At any stage, the RAC option can be unlinked to use the same home for single-instance Oracle databases. You can also run a single instance database from a RAC home by setting the
cluster_database to FALSE.
