Abstract: A system includes determination of a plurality of database configuration checks, execution of the plurality of database configuration checks against database configuration data to generate, for each of the plurality of database configuration checks, a respective result, display of one of the respective results, the displayed respective result associated with a negative result outcome, and display of information to assist resolution of the negative result outcome.

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.

Abstract: 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.

Abstract: A system and a method for installing software upgrades in a distributed computer system with no downtime. 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. An execution in progress of a service request is also redirected from the first instance of the cluster to the second instance of the cluster. The execution in progress proceeds from a state that is saved on a public store by the first instance of the cluster. 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. An execution in progress of a service request is also redirected from the second instance of the cluster to the upgraded first instance of the cluster.

Abstract: 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.
