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.

Zero downtime mechanism for software upgrade of a distributed computer system

A system and method are described for performing application loading and visualization. In one embodiment, an application is accessed on a client to be deployed on the server. The client is in communication with machines having resources corresponding to the application. The application is then deployed on the server, and the deployed application on the server references a copy of the resources that already resides on the server.

Application loading and visualization

A system for an accounting infrastructure, including monitoring and reporting, for individual services within a composite service. An accounting engine integrates with the composite service to monitor components and parameters of at least one service in the composite service, to provide reporting on the measurements and statistics associated therewith over time. The accounting engine aggregates data for components and services. One example provides the accounting infrastructure as an object-oriented program model, instantiating statistics as objects. The reporting distinguishes each statistic allowing analysis and optimization of processes and services.

Service accounting method and apparatus for composite service

According to one aspect of the invention a graphical user interface is provided. The graphical user interface includes a window displaying a first item and a menu listing a second item. Selection of the first item within the window and the second item in the menu helps to define a reference created between the first item and a target software component. The first item may be a source software component, a page, or a servlet. The second item may be the target software component or an interface to the target software component. The graphical user interface may also include a second menu listing the interface to the target software component. The source and target software components may be session or entity beans. The interface may be a remote, remote home, local, or local home interface.
