Hi Thank you David for your response. I need Load Balancing of the database cluster formed with 2 or more database server. Several clients can to send queries request (read and write ) to the database servers, who are nodes of the cluster. So with the load balancing, the answers to the request, can response any server available, which don't attend a request in this moment. I see about master-master server, which can offer load balancing, but that say it's worse than a only server, caused by locking of the write work. and then, I search other best solution. So I mentioned the master-hot standby. In this page: http://www.postgresql.org/docs/current/interactive/high-availability.html says: one that can accept connections and serves read-only queries is called a *hot standby* server. > You say you want it for performance, but when a system dies you will need > to be able to support your entire workload on one box. > Please, Can you explain me more ? -- Sayuri Komatsu _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [email protected] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
