Here is one of the queries that was put across to me (Sumant Renukarya) by one of our clients using IBM Rational Team Concert; a question that was a bit like a puzzle:

'Where can I find a specific Apache Tomcat patch for AIX server? An AIX specific patch is not available for download'.

Though it sounded like a simple FAQ, it had to be answered judiciously as the number of AIX servers which were being patched, were in the range of 90 to 100!

After thorough research and brainstorming, it was confirmed that there is no separate installer for different flavours of UNIX, for Apache Tomcat server. Essentially, you need to download and use the default installer available for the single flavour of UNIX from the Apache Tomcat website, which serves for AIX as well.

Here is a Sample Scenario:
An issue was reported with Apache Tomcat Release bundled with Jazz V4.0.0.1 and there was a need to upgrade the patch of Apache Tomcat server from the default 7.0.25 to 7.0.34. This was for an AIX server installation of the Apache Tomcat server, bundled with IBM Rational Team Concert.

From the http://tomcat.apache.org site, all the installer needed to download and use was 'apache-tomcat-7.0.34.zip', found by browsing into the location: http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.34/bin/
This particular patch is for general UNIX flavors and holds good for AIX servers as well.

I hope this helps some of you avoid the time in researching which download to use when updating your AIX Apache Tomcat server!
