Teradata 12 Client on 8.3/AIX/WebSphere

[jue]

Has anyone set up Teradata to work on Cognos 8.3 in an AIX/WebSphere environment. The documentation isn't brilliant and having done all I think i need to do....it still isn't working. When I test the data source, I get the very useful Cognos message "The report server is not responding". I must be missing something, but can't see the wood for the trees.

Does anyone have a do this, do that guide???
