Hi, Haha..these points I brought up I feel are pretty important ones to the success of clustering. I was told that Orion's clustering capabilities are no where near as good as big-name app servers, and I fought hard to disagree with that. But now I need to see proof. While the argument of replicating sessions to all servers versus a "buddy" setup like WebLogic and SilverStream do it (only two servers do object replication, thus making it faster since the traffic on the network to hit every server on the farm is reduced, as well as object creation time is reduced, as well as memory overhead (all systems having to have enough memory for all the servers objects each) ). My main need is that when a server goes down, then comes back up, that it immediately gets replicated the rest of the sessions on the farm, as well as if we add a new server to the mix. I would think Orion employs some sort of pinging system to every 15 seconds or so ping on the port and ip, and every server "broadcasts" on the same port. As soon as it "hears" the other server..it is replicated to or replicated from (which ever way it may go). The other thing..ofcourse, is to make sure that if we use a load-balancer and two servers, and one goes down, that the clients session stays alive and they don't know what is happening..other than maybe a little drain if there is a lot of activity. I am anxiously awaiting the replies on these questions..because I can't deploy on Orion if it can't do this type of session fail-over and automatic session replication when servers restart or are added. On the other hand, at least I am getting the chance to deploy on Orion now..instead of WebLogic. I almost cried when my boss finally agreed to use Orion, even if its for a time so that we can evaluate iPlanet and WebLogic. At least it moves us off of IIS/JRUN 2.3, and into the Servlet 2.2/JSP 1.1 domain, along with the ability to start EJB deployment. > -----Original Message----- > From: Dylan Parker [mailto:[EMAIL PROTECTED]] > Sent: Friday, August 25, 2000 9:59 PM > To: Orion-Interest > Cc: Kevin Duffey > Subject: Re: Orion clustering..need some detailed info > > > My, god.. you have expressed every single point that we are also fighting > with over here =) Orion team... you mentioned earlier that there was > Cluster-Guide in the works... what's happening with it?
