  • Virtual flight recorder hosted by system tracing facility
    Patent number: 8201027
    Abstract: A method utilizes a virtual flight recorder to harvest a subset of events being collected by an active system tracing facility during operation of a computer system. The virtual flight recorder is “virtual” from the sense that it is not specifically instrumented into a component with which the virtual flight recorder is associated, which eliminates the burden on developers to specifically instrument components of interest, and minimizes the impact on system performance as a result of performance metric collection.

  • Implementing feedback directed deferral of nonessential DASD operations
    Patent number: 7761658
    Abstract: A method, apparatus and computer program product are provided for implementing feedback directed deferral on nonessential direct access storage device (DASD) operations. A kernel DASD I/O manager maintains a queue depth count value for a DASD unit and maintains a busy flag that indicates when the queue depth count value is greater than a predefined threshold. The kernel DASD I/O manager defers optional operations responsive to the busy flag being set for the DASD unit.
