Commitment of transactions in a distributed system

a distributed system and transaction technology, applied in the field of distributed systems, can solve the problems of not being able to achieve the effect of two-phase commit protocol, not being able to efficiently commit transactions, and still being more message-intensive than necessary

Problems solved by technology

The two-phase commit protocol, however, is not really message efficient because during phase one, the coordinator node sends a message to each participant node to prepare to commit the transaction.
Thus, although a 2IC system requires less messaging than a 2PC system, it is still more message-intensive than necessary.

Abstract

A computer program product and system for committing transactions in a distributed system are provided. The method, computer program product, and system provide for receiving a request from a client to commit a transaction at a coordinator node in the distributed system, tracking a tail log sequence number for every other node in the distributed system, determining a max log sequence number associated with the transaction for each participant node in the distributed system, and committing the transaction at the coordinator node when the tail log sequence number for each participant node is greater than or equal to the max log sequence number associated with the transaction at the respective participant node.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Under 35 USC §120, this application is a continuation application and claims the benefit of priority to U.S. patent application Ser. No. 11 / 312,994 entitled “Commitment of Transactions in a Distributed System”, all of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates generally to distributed systems. More particularly, the present invention is directed to commitment of transactions in a distributed system.BACKGROUND OF THE INVENTION[0003]A distributed system is a multi-node system in which data is stored in various databases. Nodes can be any data processing system, such as a computer system. Although each database can only be accessed through one node, more than one database may be accessible through a node in the distributed system. The nodes in a distributed system can be connected to one another through a network, such as a local area network (LAN) or a wide area network (WAN). In addi...
