A method, computer program product and computer system for coordinating data collection from a component of a data processing system is disclosed. The component registers with a dispatcher, wherein the component is a computer resource of the data processing system and is configured to accept at least one query, and the registration comprising data types handled by the at least one component, wherein the dispatcher is allocated computer resources of the data processing system. The component receives from the dispatcher a notification to perform the query against specified data structures, wherein the query comprises an action. The component, responsive to receiving notification, determines whether data structures of a data type specified in the query are handled. The data processing system runs the query to determine whether the query is satisfied. The data processing system executes the action.

A method, system, and computer program product for fast cancellation of an I/O request in a data processing system are provided in the illustrative embodiments. A first component in a stack comprising a plurality of components determines whether a memory buffer associated with the I/O request is valid, the memory buffer being an addressable area in a memory in the data processing system. The first component, responsive to the memory buffer being valid, creates a first request data structure corresponding to the I/O request, wherein the first request data structure includes a reference to the memory buffer. The first component passes the first request data structure to a second component in the stack.

Provided are techniques for the tracing of computer processes and, more specifically, to techniques that enable a work unit to be traced across multiple processing components. A data structure is created and associated with a work unit. The first time a unit of work is processed a tracing context is retrieved form a pool and associated with the data structure. As the unit of work is passed from component to component, the data structure is passed so that each component has access and is able to augment the same tracing context associated with the unit of work.

In a method for managing resources in a virtualized computing environment, a command to initiate execution of an operating system image dump process for a logical partition of the virtualized computing environment is received while the logical partition is in a process of terminating. One or more resources that are allocated to the logical partition that will not be utilized by the logical partition during execution of the operating system image dump process are determined. A notification to a hypervisor program in the virtualized computing environment is sent. The notification identifies the one or more resources. One of the one or more resources is reallocated. The operating system image dump process is executed.

Threads of a multithreaded application may be scheduled to different cores and executed in various orders and at various frequencies. Controlling how the threads are scheduled and clock rates of processor cores enables testing multiple possible execution scenarios, which may force previously unknown timing window problems to occur. These timing window problems may then be detected.

A method, system, and program product is provided for reducing redundant validations for live operating system migration. A control point caches at least one validation inventory that is associated with a logical partition (LPAR). The control point sends the cached validation inventory to a virtualization manager upon an activation of the LPAR associated with the validation inventory. The control point invalidates the cached validation inventory upon notification from the virtualization manager that the validation inventory is changed and is no longer valid. The control point re-validates the validation inventory.

The present disclosure includes a method for migration of a first virtual function of a first device located on a PCI bus and accessible by a device driver using a virtual address. A second virtual function is created on a second device. A base address is determined for the second virtual function as a function of a logical location of the second device within the PCI structure. An offset is determined for the second virtual function as a function of the base address and the virtual address. The device driver is notified that the first virtual function is on hold. The offset is stored in a translation table. The device driver is notified that the hold has been lifted. Accesses to the virtual address and by the device driver to memory of the second virtual function are routed based upon the offset in the translation table.
