The idea behind clustering (in terms of Tru64 TruClusters) is to provide
two options to the user. The first is to provide a mechanism for basic
failover between two or more AlphaServers. In its simplest form, you set
up a cluster with two nodes. One node runs your applications. If
something happens to that node's hardware or software, the applications
"fail-over" to the other node.
The other main reason people implement TruClusters is to use multi-instance
or distributed applications. With a TruCluster, you can run applications
like Apache on all nodes in a cluster, taking advantage of all of them for
routing and processing messages. If you use a true distributed application
like Oracle Parallel Server, you get full parallel processing across all
members of the Cluster.
This is obviously a very broad overview of what a TruCluster can do. Feel
free to ask questions. Better still, come take the TruCluster class I'm
teaching in Boston the week of 10/9. :-)
