Abstract
Disclosed are techniques for migrating the execution of a task from a first host system to a second host system by copying a snapshot of data required for starting the execution of a task from memory of the first host system to memory of a coupling facility, monitoring the execution of the task on the first host system, and, upon detecting failure of the execution of the task on the first host system, initiating execution of the task on the second host system by copying the snapshot of data from the memory of the coupling facility to the memory of the second host system.
