Abstract
Problems of unplanned dynamic backward error recovery for asynchronous process systems are considered. A new recovery technique that allows transparent dynamic structuring of processes based on the concept of d ynamic conversations is proposed. The properties of these conversation s are investigated, and a dynamic scheme of consistent recovery (rollb ack) relying on them is proposed. To check resource expenditures durin g recovery, four types of control over conversations are introduced. B oth centralized and decentralized algorithms of the scheme's operation are discussed. Problems of nested rollback of dynamic conversations a re also examined.
