Typically, the computer on which you want to install Oracle Database is connected to the network. The computer has local storage to store the Oracle Database installation. It also contains a display monitor and DVD drive. This appendix describes how to install Oracle Database on computers that do not meet the typical scenario. It describes the following cases:

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 host name. In addition, you can set up aliases for the host name. By default, Oracle Universal Installer uses the
ORACLE_HOSTNAME environment variable setting to find the host name. If
ORACLE_HOSTNAME is not set and you are installing on a computer that has multiple network cards, then Oracle Universal Installer determines the host name from the
Clients must be able to access the computer either by using this host name or by using aliases for this host name. To verify, ping the host name from the client computers using the short name (host name only) and the full name (host name and domain name).
Note:Both tests must be successful.
In Bourne, Bash, or Korn shell:
$ ORACLE_HOSTNAME=somehost.example.com $ export ORACLE_HOSTNAME
In C shell:
% setenv ORACLE_HOSTNAME somehost.example.com
A computer with multiple aliases is registered with the naming service under a single IP but with multiple aliases. The naming service resolves any of those aliases to the same computer. Before installing Oracle Database on such a computer, set the
ORACLE_HOSTNAME environment variable to the computer whose host name you want to use.
You can install Oracle Database on a non-networked computer. If the computer, such as a laptop, is configured for DHCP and you plan to connect the computer to the network after the Oracle Database installation, then use the
ping command on the computer on which you want to install the database to check if the computer can connect to itself. Perform this step by first using only the host name and then using the fully qualified name, which should be in the
Note:When you run the
pingcommand on the computer itself, the
pingcommand should return the IP address of the computer.
ping command fails, then contact your network administrator.
If you connect the computer to a network after installation, then the Oracle Database instance on the computer can work with other instances on the network. The computer can use a static IP or DHCP, depending on the network to which you are connected.
