Abstract:
A method for coordinating resource modification transaction requests to reduce message traffic in a computer implemented transaction processing system, the transaction processing system operating on one or more processors each having a plurality of resources that can be changed by said transaction processing system, the method comprising the steps of:receiving a transaction request to modify one or more of said plurality of resources and assigning said transaction a global identifier;creating a first coordinator for controlling modification of said one or more resources;importing said transaction request to a plurality of subordinate transaction manager domains containing resources, said domains being organized as a hierarchy of superior and subordinate transaction manager domains, by creating a subordinate coordinator for each of said domains for controlling modification of said one or more resources in said domain, and encapsulating said global identifier, and a reference to a superior domain to which the subordinate domain is hierarchically related;dynamically registering said subordinate coordinators with the coordinator of said superior domain only when the subordinate coordinator is coordinating resources that are modifiable by a transaction;sending a transaction messages from superior coordinators only to registered, directly subordinate coordinators, thereby reducing message traffic.
