Brian, glad I made your day! :-) :-) :-)
Actually, I knew the fact that ISGLOCK has only *locks* in its structure. After all, I use response times and error times of ISGLOCK as a performance indicator on the basis 'if it's bad for ISGLOCK, it must be worse for everyone else'. Note that I was rather vague about how the IRLM structure and the DB2 buffer pools work! (Because I simply don't know about it!) And I had hoped to get Bill Neimans attention because I always wanted to know *if* the sizer determines sizes by knowing about *how* the structure is used. (In the old days, there was a general section in the PR/SM book that gave this information. The book wasn't really updated on a regular basis to include the new(er) structures!) But thanks for the reference to the book. One of these years, I'll try to read it, too! But having thought about Martins question last night while working in the garden: I am convinced that the answer for basically *all* structures is the same: The ever famous "it depends!" (Now Martin, as a performance guy, don't you just like an answer like this?) Best regards, Barbara -- GMX startet ShortView.de. Hier findest Du Leute mit Deinen Interessen!
