If youchoose to create a database, youcan then select the type of database youwant
to create, as shown in Figure 3-3 for Oracle Database 11g. The different types of
databases will be created with different default configuration values.
The alternative method for creating a database is to create or edit an existing SQL
script that executes the various required commands. Most Oracle DBAs have a preferred
script that they edit as needed. In Oracle7 and Oracle8, youexecu ted the
script using a character-mode utility called Server Manager; since Oracle8i, you
could use SQL*Plus. The Oracle software CD-ROM also includes a sample script
called BUILD_DB.SQL, described in the Oracle documentation. Today, most users
choose to create the database with the standard installer interface.
Configuring Oracle Net
Oracle Net (known as Net8 for Oracle8 and Oracle8i and SQL*Net prior to Oracle8)
is a layer of software that allows different physical machines to communicate for the
purpose of accessing an Oracle database.
