Abstract: Methods, media and systems for managing a distributed application running in a plurality of digital processing devices are provided. In some embodiments, a method includes running one or more processes associated with the distributed application in virtualized operating system environments on a plurality of digital processing devices, suspending the one or more processes, and saving network state information relating to network connections among the one or more processes. The method further include storing process information relating to the one or more processes, recreating the network connections using the saved network state information, and restarting the one or more processes using the stored process information.

Abstract: Systems for recording, searching, and outputting display information are provided. In some embodiments, systems for recording display information are provided. The systems include a virtual display that: intercepts display-changes describing changes to be made to a state of a display; sends the display-changes to a client for display; records the display-changes; and a context recorder that records context information describing a state of the display derived from a source independently of the display changes and independently of screen-images. In some embodiments, the systems further include a display system that generates an output screen-image based at least in part on at least one of the display-changes and in response to a search of the context information. In some embodiments, the virtual display further records screen-images; and the display system further generates the output screen-image based at least in part on a recorded-screen-image of the recorded screen-images.

Abstract: Methods, systems, and media for enabling a software application to recover from a fault condition, and for protecting a software application from a fault condition, are provided. In some embodiments, methods include detecting a fault condition during execution of the software application, restoring execution of the software application to a previous point of execution, the previous point of execution occurring during execution of a first subroutine in the software application, and forcing the first subroutine to forego further execution and return to a caller of the first subroutine.

Abstract: A method for recording and replaying execution of an application running on a computer system using a program module is provided. The method includes recording events which result from the execution of the application including a non-deterministic event, wherein the program module deterministically records the non-deterministic event, saving the recorded events for deterministic replay of the recorded execution, restoring the saved recorded events, and deterministically replaying the recorded execution of the application.

Abstract: Methods, media and systems for maintaining execution of a software process are provided. In some embodiments, methods for maintaining execution of a software process are provided, comprising: suspending one or more processes running in a virtualized operating system environment on a first digital processing device; saving information relating to the one or more processes; restarting the one or more processes on a second digital processing device; and updating an operating system of the first digital processing device.

Abstract: Methods, media and systems for enabling a consistent web browsing session on different digital processing devices are provided. In some embodiments, a method includes storing data relating to one or more virtualized processes associated with a web browsing session on a first digital processing device in a storage device; connecting the storage device to a second digital processing device running an operating system; and restarting the one or more virtualized processes in the operating system of the second digital processing device using the stored data.
