Sometimes the speed of Oracle releases is hard to keep up with, as Antony Reynolds discovered and shared with us in his blog. Even when product combinations are certified with each other.
Oracle 11g database
The 11g release 1 of the database has been out long enough. It cannot be considered bleeding edge nowadays. So both from a features and longevity perspective it makes sense to deploy SOA Suite on a 11g R1 database. This blog post will show you the additional steps that are needed to install SOA Suite 10.1.3. on 11g R1.
Oracle Enterprise Linux
The SOA Suite installer checks whether the OS it is running on, is supported. At the time 10.1.3 was first released, Oracle Enterprise Linux 5 (OEL) wasn´t on the list. The result is that the installer fails. There is a patch (6339508) available and a blog post that describes the solution.
