Despite Specifying FQDN Using OUI_HOSTNAME, Installer Configures Single Sign-On URLs With Hostname Only (Doc ID 473639.1)

Last updated on AUGUST 16, 2023

Applies to:

Oracle Fusion Middleware - Version to [Release AS10gR2]
Oracle Application Server Single Sign-On - Version to [Release 10gR2 to 10gR3]
Information in this document applies to any platform.
Oracle Application Server Single Sign-On - Version: to
This problem can occur on any platform.


After successfully installing OracleAS 10g Rel 2 Identity Management or Oracle Identity Management, the Single Sign-On URLs unexpectedly feature only the hostname - rather than the fully qualified hostname.

For example:

Login to Single Sign-On via a partner application such as Oracle Portal.
The login works fine but the url returned by Single Sign-On only features the hostname


At install time the OUI_HOSTNAME parameter was specified e.g

runInstaller OUI_HOSTNAME=host.domain


setup.exe OUI_HOSTNAME=host.domain

This was done after reading this advice given in the Installation Guide

4.10.2 Hostname for OracleAS Single Sign-On

If you are installing OracleAS Single Sign-On, and your hosts file contains only the hostname of your computer, without the domain name, then you will only be able to sign on to the Single Sign-On server using the hostname by itself (without the domain name).

If you want to require a domain name when connecting to the Single Sign-On server, you can edit the hosts file to include the domain name. If you do not want to edit the file, you can use the OUI_HOSTNAME command-line parameter to the installer to override the value in hosts. For example:

prompt> mount_point/1012disk1/runInstaller OUI_HOSTNAME=host.domain
