System for detecting global deadlocks using wait-for graphs and identifiers of transactions related to the deadlocks in a distributed transaction processing system and a method of use therefore
 In a distributed transaction processing system, deadlocks generated between global transactions so as to stretch over a plurality of resource managers which access database can be detected, thus aiming at effective use of resources. For this reason, the system is configured in such a manner that a transaction manager for collectively managing global transactions is provided with global deadlock detector for detecting deadlocks generated so as to stretch over a plurality of resource managers between a plurality of global transactions which result from wait-for relation as to occupation of hardware resources.
