  • Database contention and deadlock detection and reduction within application servers
    Patent number: 8041686
    Abstract: A method in a data processing system for detecting and reducing database contention and deadlock caused from within an application server. A determination is made as to whether a set of parameters in a statistical model indicates contention. If the set of parameters in the statistical model indicates contention, an application server administrator is notified of the contention and the number of threads in an application server pool is reduced. If the set of parameters in the statistical model indicates contention is reduced, the number of threads in the application server pool is increased.

  • Software Memory Leak Analysis Using Memory Isolation
    Publication number: 20110093748
    Abstract: A computerized method, program product, and a service that allocates and isolates leaky memory during the execution of an application in a data processing system. A memory controller having several components first identifies a leaky section of memory and delegates to an allocation component to allocate more memory if possible. If, however, the problematic memory section should not be allocated more memory, an isolator component can isolate the memory section and further divide the memory section into subsections and so on. Each section and each subsection may then be tested to determine if more memory can be allocated, tested to determine if memory resources are strained so as to identify the application or its component causing the strain and then binding the memory. Each section and subsection and further divided and isolated until the leaky portion of memory is identified, and as a result, the software component causing the leak can also be identified.
