Abstract
A fault-tolerant method and system for processing global transactions in a distributed database system. If a fault occurs in the distributed database system, a transaction management system will suspend the processing of a transaction and renew it when the fault is remedied. The transaction management system identifies one or more sites in the distributed database system that contain data needed for a global transaction and divides each transaction into subtransactions for processing at one or more identified sites. If a fault occurs in the distributed database system, the transaction management system maintains the status of each subtransaction. When a fault in the distributed database system is corrected, the transaction management system updates the status of each subtransaction and restarts processing of the transactions.
