A method and system are provided for managing application programs with non-responsive user interfaces, possibly due to a bottleneck in handling events/messages. The method and system make an apparently frozen application user interface responsive so as to permit alternative tasks be executed or close the hung application. This is enabled by implementing routines to (a) detect if an application is hung, (b) replace the user interface for the hung application with a ghost interface, implemented by a separate thread, that permits system functionality such as sizing, minimization and closing of the application, and (c) destroying the ghost interface if the hung application becomes responsive again along with restoring the application's user interface along with updated event queues. Furthermore, creation of the ghost user interface is accompanied by placing a high priority special event in the hung application's queue to detect renewed responsiveness without requiring explicit monitoring.

A system and method for enabling multiple processes to efficiently log events is described. A client executable module that needs to log an event may interface with a module or component referred to as a “client-side logging component”, passing various types of information regarding the event, such as an associated event level, one or more event associated event categories, an informational message, etc. The client-side logging component may maintain event logging criteria specifying which types of events should be logged. If the event should be logged, the client-side logging component may queue the event information and return execution control the client module. The event information may then be asynchronously retrieved from the event queue and sent to a server-side logging component. The server-side logging component may persistently log the event information in any of various ways, e.g., by storing it in a file, a database, etc. Processes running on multiple computers may call the server-side logging component to log events, via a client-side logging component instance associated with the process. A logging administration tool may be utilized in order to set event logging criteria. In response to being configured with new event logging criteria information, the server-side logging component may automatically propagate the logging criteria information to each of the client-side logging components. The client-side logging components may then being using the new logging criteria, dynamically changing the filtering of events that are sent to the server-side logging component.

A system for creating multiple independent terminals of grouped input and output devices connected to and for operation by a single computer comprising a configuration module for simultaneously providing unique output commands to ungrouped output devices to cause the output devices to respectively provide a unique input directive to a user; the configuration module also for receiving unique input commands from individual ungrouped input devices, each unique input command corresponding to a respective one of the unique output directives; and an association module for, in response to the receiving, commonly associating with a unique group identifier each of corresponding input and output devices and respective ones of multiple pointers and focuses.

A method, system, program product and computer data structure for providing for two levels of server virtualization. A first hypervisor enables multiple logical partitions to share a set of resources and provides a first level of virtualization. A second hypervisor enables multiple, independent virtual machines to share the resources that are assigned to a single logical partition and provides a second level of virtualization. All events for all of the virtual machines within said single logical partition are grouped into a single partition-owned event queue for receiving event notifications from the shared resources for that single logical partition. A request for an interrupt is signaled for the grouped events from the partition-owned event queue for the demultiplexing of grouped events, by the machine, from the partition-owned event queue into individual, virtualized event queues that are allocated on a per virtual machine basis.

Web-based event/state-driven mechanisms and methods for simplifying communication between networked multifunction devices, such as copiers, printers, facsimile machines and multifunction devices using a networked database for the creation and presentation of device metrics and status data. Web-based multifunction performance metrics and calculations themselves are created within concurrent (multiple instances) of Web objects, wherein a Web object is a self-contained entity with data and a state machine lifecycle. State changes inside and outside the Web object are made by sending events to event queues and routing them to other state machines within other Web objects or instances of the same Web object. Data and events between Web objects are formed into a regular event syntax providing a simpler method of communication than those of procedural programming approaches. The arguments of the events are processed by specific instances of state machines that compose each Web object to perform an appropriate action. The metrics displays and corresponding calculations within the Web object's state machine are highly self-contained and concurrent, hiding networked database contention and database locking, and enforcing atomicity with it's runtime software. Calculations are performed and displayed from within a very small context within each Web object's state minimizing external communications and further simplifying software application development efforts.

An Event Manager receives events requiring action. The events are parsed into event action types which are placed in an Event Queue. Program agents in a pool of agents are dynamicly instantiated and retired from the pool based on the number of queued events by type. Program agents, when available, initiate a search for a work entry on the Event Queue that is of a type that the agent can handle. When an agent finds work, the corresponding Event Queue entry is marked as assigned to the agent and the agent performs the action associated with the work entry.
