Abstract: A delay in a configuration changing operation of a computer system including a manual procedure and an automatic procedure is detected. Based on actions of a setup tool or a configuration tool operated on IT resources, an event which occurs corresponding to the start and the end of a manual procedure is detected and the actual time of the manual procedure is calculated from the detection time points. Next, a delay rate is calculated from a scheduled time and the actual time of the manual procedure, and an end time point of an incomplete operation procedure is estimated from an estimated time required for the manual procedure with the calculated delay rate taken into account and from a time required for the automatic procedure to determine whether the scheduled operation will be finished within a period.

Abstract: Exemplary methods, apparatuses, and systems determine a list of virtual machines to be subject to a corrective action. When one or more of the listed virtual machines have dependencies upon other virtual machines, network connections, or storage devices, the determination of the list includes determining that the dependencies of the one or more virtual machines have been met. An attempt to restart or take another corrective action for the first virtual machine within the list is made. A second virtual machine that is currently deployed and running or powered off or paused in response to the corrective action for the first virtual machine is determined to be dependent upon the first virtual machine. In response to the second virtual machine's dependencies having been met by the attempt to restart or take corrective action for the first virtual machine, the second virtual machine is added to the list of virtual machines.

Identifiers of the subset of the plurality of threads are presented. The subset of the plurality of threads may have their execution directly blocked and/or indirectly blocked by a lock on the mutex by the first thread. In embodiment, the first thread is halted in response to the first thread encountering a breakpoint, and the subset of the plurality of threads do not halt in response to the first thread encountering the breakpoint.

Abstract: The present invention provides discrete, depleting chips for allocating computational resources for obtaining desired service level characteristics, wherein discrete chips deplete from a maximum allocated amount but may, in an optional implementation, be allowed to be replenished through the purchase of additional chips. A number of chips are assigned to a requestor/party, known as a business unit (BU), which could be a department, or group providing like-functionality services. In one implementation, the chips themselves could represent base monetary units integrated over time.

Abstract: Configuration settings can be transferred from one machine by executing a first client application on a source machine to retrieve the configuration settings of the source machine. The configuration settings may be transformed into a platform and application independent format before being transferred to a target machine where a second client application transforms the configuration settings into platform or application dependent parameters appropriate for the target machine. In one example, the configuration parameters include a power policy that can be applied across a network.
