Abstract: In accordance with an embodiment, described herein is a system and method rule-based elasticity support in an application server environment. The method can begin with providing, at one or more computers, including an application server environment executing thereon, a plurality of deployable resources which can be used within the application server environment, one or more partitions, an administration server, the administration server comprising a diagnostic framework, a rules framework, and an elastic service manager, and a dynamic cluster for use by the one or more partitions. The method can continue with monitoring, by the diagnostic framework, metrics associated with the one or more partition and the dynamic cluster. The method can then trigger, by the rules framework, the action based upon a comparison between one of the one or more rules and the monitored metrics associated with the one or more partitions and the dynamic cluster.

Abstract: In accordance with an embodiment, described herein is a system and method for supporting interceptors in an application server environment. The method can provide, at one or more computers, including an application server environment executing thereon, a plurality of deployable resources which can be used within the application server environment, one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain, and an interceptor framework, the interceptor framework comprising a plurality of interceptors. The method can further select and trigger, on a call for a method invocation, an interceptor chosen from the plurality of interceptors. The method can interrupt, by the triggered interceptor, the call for the method invocation, wherein the interceptor is selected based at least upon the call for a method invocation.

Abstract: In accordance with an embodiment, described herein is a system and method for dynamic debugging in an application server environment. An exemplary method can provide, at one or more computers, including an application server environment executing thereon, a plurality of deployable resources which can be used within the application server environment, one or more running managed servers, the one or more managed servers being within a domain, and a debug framework, the debug framework comprising a debug patch directory, the debug patch directory containing one or more debug patches. The method can activate a selected debug patch within the domain, the selected debug patch comprising at least one class, the selected debug patch designed to gather information about the problem within the domain. The managed servers, upon activation of the selected debug patch, can remain running. The method can also deactivate the selected debug patch without requiring a restart.

Abstract: A system and method for monitoring and diagnostics in an application server environment. A system can comprise one or more computers, which can include an application server environment executing thereon, together with a plurality of deployable resources configured to be used within the application server environment, and a plurality of partitions, wherein each partition provides an administrative and runtime subdivision of a domain. A diagnostic framework, such as a WebLogic Diagnostic Framework (WLDF) can also be provided, wherein the diagnostic framework is configured to perform at least one action from the group consisting of partition scoped logging, partition scoped monitoring, and partition scoped diagnostic imaging.
