Abstract
Provided are a method, system, and article of manufacture for recovery of application faults in a mirrored application environment. Application events are recorded at a primary system executing an instruction for an application. The recorded events are transferred to a buffer. The recorded events are transferred from the buffer to a secondary system, wherein the secondary system implements processes indicated in the recorded events to execute the instructions indicated in the events. An error is detected at the primary system. A determination is made of a primary order in which the events are executed by processes in the primary system. A determination is made of a modified order of the execution of the events comprising a different order of executing the events than the primary order in response to detecting the error. The secondary system processes execute the instructions indicated in the recorded events according to the modified order.
