Install Oracle Middleware products on Oracle Enterprise Linux

If you trying to install Oracle Application Server or another middleware product (OAS, SOA Suite, OIM, etc..) on Oracle Enterprise Linux and receives the following error:

Starting Oracle Universal Installer...

Checking installer requirements...

Checking operating system version: must be redhat-Red Hat Enterprise Linux AS release 3, redhat-Red Hat Enterprise Linux AS release 4, redhat-Red Hat Enterprise Linux ES release 3, redhat-Red Hat Enterprise Linux ES release 4 or SuSE-9
Failed <<<<

This is because the product was released before Oracle Enterprise Linux, so the installer is not aware of this release.

You can use two diferents workarounds for this situation:

1. Run installer with -ignoreSysPrereqs argument
./runInstaller -ignoreSysPrereqs

2. To change the /etc/redhat-release file to have the version name to that of "Red Hat Enterprise Linux AS release 4 (Nahant Update 4)" (or something else sopported by installer)


Enjoy.
