Extensible patch management

摘要

Extensible patch management provides mechanisms by which data, database and binaries for one or more components of an application may be updated. The patch framework extends patch related functionality at different devices as needed to perform a software patch in a manner that allows such functionality to be retained at the device. Additionally, the patch framework is platform independent and thus allows the same patch related software to be distributed and executed across different platforms.

1. A method comprising:
receiving by a data processing device a list of tasks that define a patch for application at the data processing device; instantiating a virtual machine on the data processing device for use in applying the patch; determining whether a task declared in the list of tasks is unsupported by bytecode currently associated with the virtual machine; upon determining that a task is unsupported by the bytecode currently associated with the virtual machine, obtaining additional bytecode to implement the unsupported task; and executing the additional bytecode at the virtual machine to perform the unsupported task with other tasks in the list to apply the patch.
