Abstract
In a distributed computer system with cluster architecture, a number of service requests are redirected from a first instance of the cluster to a second instance of the cluster for execution. A software patch is applied to one or more software components running on an application server node of the first instance of the cluster. A number of service requests are redirected from the second instance of the cluster to the first instance of the cluster for execution. The software patch is applied on the one or more software components running on an application server node of the second instance of the cluster. A number of new service requests are directed to the upgraded second instance of the cluster for processing.
