This question is somewhat associated with my lsuosstats global area latch question recently posted. We were running a load test and so many of the queries where probably doing the exact same thing. So the event "cursor: pin S wait on X" which bubbled to the top. From Tanel Poders web site: "A mutex differs from a latch in that there would be many more requestors backed up on a latch, whereas a mutex in this case protects just one cursor." Since this was a test, I am assuming that this is nothing to be concerned about now, but if I were to become concerned about it, does anyone know how they could approach this event specifically? Is there anything we can do about it now - because we are testing? Joel Patterson Database Administrator 904 727-2546
