DB2 LUW, that is
There are two flavors of DB2, the one that runs on IBM Z and the one that runs on Linux, Unix, and Windows (LUW). Last I knew, they did not share a code base, or shared very little. This affects the LUW version. In future I would suggest making that clear in the article. Perhaps even the headline.
Yes, yes, I know IBM is a failure as a company because it's losing money (except for Z) and no one uses Z (except those who trumpet about their third 5-year plan to migrate to whatever is trendy these days) and so on and so forth ad infinitum ad nauseam etc. etc. etc.
