I'm a developer working mostly on a Java application which interfaces with an iSeries back end (the iSeries is running OS 6.1). I consider myself to be reasonably strong on DBA and sysadmin topics (*nix and Windows) but the iSeries world is quite alien. I don't need to become an expert, I'll never be called upon to do admin work but I would like to talk the language of iSeries people. Terms are so loaded that it's very easy to get the wrong end of the stick but the iSeries admins have an exclusively iSeries background so it's quite difficult to gain a common understanding.
So, what I would love to find is a guide to iSeries systems for someone who already has a good knowledge of software and systems. Any suggestions would be greatly appreciated.
