Re: Let me be the first
Bruce - Was this piece by CRN (http://www.crn.com/sections/software/ software.jhtml?articleId=193004835) supposed to discuss the optimistic concurrency isolation currently under development? Of course, that would not explain the reference to DB2 since they do not support optimistic concurrency. If so, it might have made some interesting reading. As written, it is of little value since record-level (or row-level) locking has been available in IDS for over a decade.
