Have problems occurred? Depends, of course. For starters the weight is relative to the aggregate for the CEC - if that is only, say, 2 (with 2 LPARs weighted at 1 each) you ought not expect to have any problems at all. Probably not your case though. Is your LPAR sharing any resources with any others? GRS or MIM come to mind here... if you need to "run" those on your resource challenged LPAR then you are a troublemaker. If your whimpy LPAR is a monplex, sharing nothing then no, it isn't a problem per se. More of an opportunity to catch up on your reading while you wait for it to respond. (We do it with a sandbox system and it is pretty pokey when the other LPARs are guzzling MIPS. Still, it all works but at an HO-scale. Just not the way to run a real railroad.) -- Tom Schmidt Madison, WI
