I might agree with you, but I would want to try it first. :Just remember that HP-UX 10.20 does not like to have more than two (2) :Informix virtual shared memory segments, remember? More than two (2), :and they get paged out. HP-UX problem, right? I believe that was more than 3 segments and they got swapped out. We always shot to tune the virtual seg size large enough so that additional virtual segments were never allocated under HP/UX. Since you commonly have a shared memory message segment along with the resident and virtual portion, 3 was the magic number. Dave ********** "Everybody plays the fool, sometimes."
