DB2 Express for RTC 3.0 on Linux

I am trying to install RTC 3.0 on Linux using DB2 Express as the enterprise database. I can't seem to find the correct installation image for DB2 Express nor instructions on how to do the DB2 install and setup with RTC 3.0.

From https://jazz.net/downloads/rational-team-concert/releases/3.0?p=optionalPrograms

Jazz Team Server and the Change and Configuration Management application support IBM DB2 Enterprise Server Edition. For platforms that don't support Enterprise Server Edition (32-bit Linux), IBM DB2 Workgroup Server Edition may be used. You can obtain a trial download of one these DB2 editions or the free DB2 Express-C for deployments of fifty developers or less.
