Abstract

Various examples are directed to systems and methods for coordinating a non-repudiable atomic commit transaction. A client may direct a transaction request to a transaction manager, where the transaction request comprises a transaction origin token. The transaction manager may create a transaction submission token and provide it to the client. The transaction manager may create a digest of a first work item to be executed by a first resource manager and send the digest to the first resource manager. The first resource manager may send the transaction manager a work item receipt token. The transaction manager may send the resource manager the transaction origin token.

Claims20

Dependent claims

A computer-implemented system for coordinating a transaction, the system comprising:

at least one processor and operatively associated memory, wherein the at least one processor is programmed to execute a transaction manager for coordinating an atomic commit transaction, wherein the transaction manager is programmed to:
receive from a client a transaction request, wherein the transaction request comprises a description of the transaction and a transaction origin token digitally signed with a private key of the client;
create a transaction submission token digitally signed with a private key of the transaction manager;
send the transaction submission token to the client;
generate a digest of a work item from the transaction;
send the digest of the work item to a resource manager for performing the work item;
receive from the resource manager a work item receipt token digitally signed with a private key of the resource manager;
send the work item and the transaction origin token to the resource manager;
receive from the client a commit instruction and a completion token digitally signed with the private key of the client;
send the resource manager a prepare instruction;
receive from the resource manager a prepare token digitally signed with the private key of the resource manager;
determine that all resource managers taking part in the transaction have returned prepare tokens;
and
send the commit token to the resource manager.

A computer-implemented method for coordinating by a transaction manager executed by at least one processor, the method comprising:

receiving, by the transaction manager and from a client, a transaction request, wherein the transaction request comprises a description of the transaction and a transaction origin token;
creating, by the transaction manager, a transaction submission token;
sending, by the transaction manager, the transaction submission token to the client;
generating, by the transaction manger, a digest of a work item from the transaction;
sending, by the transaction manager, the digest of the work item to a resource manager for performing the work item;
receiving, by the transaction manager and from the resource manager, a work item receipt token digitally signed;
and
sending, by the transaction manager the work item and the transaction origin token to the resource manager.
