I've now completed this upgrade on both Sun Ray servers. Users conveniently logged out on the weekend. I'm impressed with the upgrade procedure. They are set up in the same primary/secondary failover configuration as before. Most users do not use smart cards. Only the few that do have persistent sessions. I notice that after the upgrades, almost all of the idle sessions (dtgreet processes) are on the first server that was upgraded. Two that I killed from the GUI moved to the second server. One more moved by itself overnight. I notice also that people who log in without a smart card always have sessions on the server where dtgreet was running. There seems to be no load balancing in this case. Is that supposed to be how it works? I know that if you do a control-moon on an idle Sun Ray, it will switch over to the other server most of the time, but we don't want to teach users that. I thought that load balancing was more dynamic than this. -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking- _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
