Abstract: Replacement of software in an operating computer system, and in particular, synchronization of state transfer between processes within the old software to processes within the new software. The synchronization of state transfer between processes executing in the old and the new software includes the following steps: preparing the old static process within the old software for a forthcoming shutdown, activating it for the state transfer, preparing the new static process within the new software to take over, transferring all resource objects in the old static process to the new static process; ordering the old static process to remove all services, terminating the old static process; and committing the new static process to take over, indicating that the new static process is the sole owner of all the resource objects previously claimed from the old static process.

Abstract: In telecommunications switching system, software is frequently modified, enhanced or replaced altogether by new versions. The implementation or integration of the new or revised software into the operational system must be accomplished in accordance with strict requirements for not disturbing the ongoing activities of the system. Therefore, it is desirable that the system not be halted while the change to the new software is made. Rather, the preferred approach is to be able to replace software modules with new versions on the fly, during system operation. The smooth modification made possible in the disclosed system allows such changes with minimal disturbance to ongoing activities. The disclosed system provides the ability to change software during operation by treating the dynamic operations of a telecommunications system as a set of parallel, independent transactions, with each transaction consisting of a series of connected activities.
