ABSTRACT:
The invention provides a method and system for re-establishing sessions between a server and its clients following a failure of the server, planned reboot of the server, or takeover by another server. At critical points within a server/client session, state is saved so as to be reliable and consistent. Upon reboot of the system, state is restored using that which was saved; returning the server to its pre-crash state and preserving sessions that were in progress prior to the reboot. Additionally, state saved by a first sever prior to failure or elective shutdown can be transferred to a second server in a takeover configuration also preserving sessions in progress.
