Hi Prasanth, Thank you very much for the reply. It definitely gives insight into LS cluster operation.I can find some info in Users_Administration Document also.
I had Cluster installation experience previously with MS Sql 2005. Never installed cluster on web servers or application servers. Is there any document where i can get the detailed configuration steps for Load Balancing of LiveServer. Or Is it that easy there is no need for documentation to do that. If its second way then i can definitely do some googling and try out. Thanks, Regards, Swapna. ----- Original Message ----- From: Prasanth Nittala To: [email protected] Sent: Tuesday, September 22, 2009 12:24 AM Subject: RE: [reddot] LiveServer Cluster Operation Hi Swapna, Ø Clustered installation doesn’t have separate licenses for installation in cluster environment. You would just have your individual LS licenses, and each LS pointing to the same Database instance, and additional configs for them to operate in clustered mode. You have some additional info on how the clustered mode operates in Live Server Users_Administration document apart from LS installation document. Ø Regarding your question about both LS instances on different IP having a common IP for external world, this is achieved through load balancer operating in front of the clustered LS instances. In standard Architecture, you would have the following in that order from End user to backend Datastore. 1) Load Balancer 2) 2 or more Web Servers behind the load balancer configured, and connecting with backend Live Servers (using mod_proxy_ajp or mod_jk in case of Apache) 3) 2 or more Live Servers in clustered mode 4) Common database instance for clustered LS instances So in your case, you need a load balancer in front of your clustered LS instances. Ø I wasn’t able to understand your question about database servers. As you would be pointing to the same Database instance, I am not sure why you were having two database servers in this context.

We have 2 independent licences for LiveServer. I installed liveserver(MySQL DB) on one system. Then while setting up LiveServer on the second system i selected the config.xml,dbsettings.ksf,dbsettings.ksf.properties and dbsettings.ksf.asn from the first installation. Then it asked me to restart tomcat. Once i restarted the tomcat, i could get the login page. Now my doubt is, i Can't understand how cluster works here. Generally cluster systems have their own individual IP but to the outside world they have a single IP. We make calls to this single IP address and depending on the availability one of them responds. But here i cant find the single IP info. Other thing being Databases are shared in cluster but, herei could see RDEUSER and RDEMASTER databases on both the database servers.The second one is using the db logins of the first system. Is there any documentation for Cluster Operation.Atleast from OT site. Do we need seperate licences for installation in Cluster Environment. Anyhelp would be thankful.
