2-22 Oracle Application Server Installation Guide
2.10 Network Topics
Typically, the computer on which you want to install Oracle Application Server is
connected to the network, has local storage to contain the Oracle Application Server
installation, has a display monitor, and has a CD-ROM or DVD-ROM drive.
This section describes how to install Oracle Application Server on computers that do
not meet the typical scenario. It covers the following cases:
■
Section 2.10.1, "Installing on Multihomed (Multi-IP) Computers"
■
Section 2.10.2, "Copying CD-ROMs or DVD-ROM to Hard Drive, and Installing
from the Hard Drive"
■
Section 2.10.3, "Installing from a Remote CD-ROM or DVD-ROM Drive"
■
Section 2.10.4, "Installing on Remote Computers"
■
Section 2.10.5, "Installing on NFS-Mounted Storage"
■
Section 2.10.6, "Running Multiple Instances from One Installation"
■
Section 2.10.7, "Support for NIS and NIS+"
2.10.1 Installing on Multihomed (Multi-IP) Computers
You can install Oracle Database on a multihomed computer. A multihomed computer
is associated with multiple IP addresses. This is typically achieved by having multiple
network cards on the computer. Each IP address is associated with a hostname;
additionally, you can set up aliases for the hostname. By default, Oracle Universal
Installer uses the OUI_HOSTNAME environment variable setting to find the hostname.
If OUI_HOSTNAME is not set and you are installing on a computer that has multiple
network cards, Oracle Universal Installer determines the hostname by using the first
name in the /etc/hosts file.
Clients must be able to access the computer using this hostname (or using aliases for
this hostname). To check, ping the hostname from the client computers using the short
name (hostname only) and the full name (hostname and domain name). Both must
work.
2.10.2 Copying CD-ROMs or DVD-ROM to Hard Drive, and Installing from the Hard Drive
Instead of installing from the Oracle Application Server CD-ROMs or DVD-ROM, you
can copy the contents of the CD-ROMs or DVD-ROM to a hard drive and install from
there. This might be easier if you plan to install many instances of Oracle Application
Server on your network, or if the computers where you want to install Oracle
Application Server do not have CD-ROM or DVD-ROM drives.
(You can install from remote CD-ROM or DVD-ROM drives; see Section 2.10.3,
"Installing from a Remote CD-ROM or DVD-ROM Drive" .)
When you install from the hard drive, the installer does not prompt you to swap
CD-ROMs. It can find all the files if they are in the proper locations (see
Figure 2–1 ).
Space Requirement
Ensure that the hard drive contains enough space to hold the contents of the
CD-ROMs or the application_server directory on the DVD-ROM. Each CD-ROM
contains approximately 650 MB. This means that if you are copying three CD-ROMs,
you need approximately 1.9 GB of disk space.
On the DVD-ROM, the application_server directory is approximately 1.6 GB.
