If Oracle DBA want a preconfigured database installed, Oracle DBA can select one of the following
database types, optimized according to usage:
If Oracle DBA want to create an custom database where Oracle DBA configure your own database
structure, you can select an advanced install.
What are your Database Configuration Options? These include your Global
Database Name, Oracle System Identifier (SID), and whether to install the example
schemas. The Global Database Name is the full name of the database which
uniquely identifies it from any other database. The global database name is of the
form database_name.database_domain as in sales.us.acme.com. The database name
portion sales is a simple name you call your database. The database domain
portion us.acme.com specifies the database domain in which the database is
located. Together database name and domain make up the Global Database Name.
Oracle recommends that you install the example schemas so that you can run
many of the examples in the documentation.
You will also be prompted to enter your database schema password for the
pre-loaded schemas such as SYS and SYSTEM, which enable you to manage and
administer the database.
What kind of storage mechanism do you want your database to use?
A database comprises several files which stores the Oracle DBA data, database meta data,
as well as information required to recover from failures. As an administrator, you decide what kind of storage sub-system to locate these files on.You can select from
the following options:
File System—Creates database files that are managed by your operating
system’s file system. You can specify the directory path where database files
are to be stored. Oracle can create and manage the actual files.
Automatic Storage Management—This is new functionality that enables you
to define a pool of storage (called a disk group) in which Oracle automatically
manages database file placement and naming. For environments with a large
number of disks, this option simplifies database administration and
maximizes performance. Disk mirroring and striping are done automatically.
Automatic Storage Management requires a separate instance to configure and
manage disks groups. Oracle DBA are guided through the creation and launching of
an Automatic Storage Management instance and its components by the
database installation process. For more information, see Oracle Database
Raw Devices—Enables Oracle DBA to manage your storage devices outside of the
operating system file system by providing Oracle with unformatted physical
disk space called raw devices. This method is primarily used in Oracle Real
Application Clusters environments. If Oracle DBA selected this option, Oracle DBA must
ensure that the raw devices have been created using an operating system
command, and that they are not being used for any other purposes or by other
If you are not certain of which option to use, go with the default selection of File
What are your Database Management Options? Here you specify whether to
manage your database centrally or locally. The central deployment mode enables
you to manage multiple targets, such as databases, and application servers from a
single console. The local deployment mode on the other hand can manage only a
single database instance. The central deployment mode requires a special agent to
be installed on the database machine. If no such agent is found, this option is
If you are setting up a single database for the first time, it is recommended that
you deploy Enterprise Manager locally. You can later install additional databases
and migrate your deployment mode to central management.
At the end of the interview a summary page displays the options that you have
chosen, space requirements, and the components that will be installed. If Oracle DBA have
chosen to install a database, that will be done immediately after the software
installation is complete.
Sufficient paging space is available.
Appropriate operating system service packs or patches are installed.
Appropriate files system format is being used.
The installer automatically sets any operating system environment variables that the
Oracle database server requires for its operation.
The Oracle Universal Installer guides Oracle DBA through an interview phase that asks Oracle DBA to specify your choices for installation and database creation. The exact sequence of pages depends on your platform. All platforms include the following choices:
What database product do Oracle DBA want to install?
Oracle DBA can install one of the following:
Oracle Enterprise Edition—Oracle’s most full featured database product providing data management for high-end applications.
Oracle Standard Edition—A less-expensive and somewhat scaled down version of the Oracle database suitable for workgroup or department level applications
Custom Install—Allows Oracle DBA to customize the Enterprise Edition by selecting products to install. Do this if Oracle DBA want to add a component to your database that would not normally be installed or prevent certain components from being installed.
