Host Files for OBIEE Installation

Applies to:

Business Intelligence Server Enterprise Edition – Version: [1905] to – Release: 11g to 11g
Information in this document applies to any platform.Oracle Business Intelligence Enterprise Edition
For example:
# Do not remove the following line, or various programs
# that require network functionality will fail.
If such a setting is in place in OBIEE, or, the install will fail, or components will fail to start after install.  To prevent this from happening, you must modify the etc/hosts file before starting installation.
For example:
# Do not remove the following line, or various programs
# that require network functionality will fail. host
nslookup (lookup on the actual host name and domain)
nslookup 123.456.789.0 (where IP address specified is that of the actual OBIEE machine)
How should the etc/hosts file be configured before Oracle Business Intelligence Enterprise Edition (OBIEE) 11g Installation.
In OBIEE, the installation allowed the etc/hosts file to have an entry using the localhost IP address.
[oracle@test ~]$ more /etc/hosts

  • The etc/hosts file needs to be changed from local host ( to the physical IP address.
    [oracle@host ~]$ more /etc/hosts
  • On Windows 7, the etc/hosts does not need to include the domain: host
  • Pre-installation checks for all platforms should include nslookups to confirm network and DNS settings. For example, the following command should return without error and the IP address and host should match those listed in the etc/hosts file:
    nslookup host (where host is the “short name” or “alias” for the host machine)
NOTE: Windows 7 is not a certified platform for Oracle Business Intelligence Enterprise Edition versions or Starting with OBIEE, Windows 7 is supported for single user in a development only environment.  For further information, please see the Certification Guide posted 
Windows 7 related comments in this note are included because many customers are installing non-production instances of OBIEE on Windows7.
