Additional Background Reading

• The JTA spec at Sun is the Java mapping of XA distributed transaction technology.
• The original XA specification by the X/Open Group: You will need this to understand the depth of XA.
• Distributed Transaction Processing, another X/Open Group spec around XA.
• Nice background reading on XA: can be used to understand why XA is the way it is.
• Transaction Processing Concepts and Techniques :this book is the bible of transaction systems.
• Concurrency Control and Recovery in Database Systems: another classic book - mainly explaining database transaction theory.
• Composite Transactions: Guy Pardon's PhD thesis - the inspiration and foundation of the Atomikos transaction model. Warning: has a heavy focus on compensation (a feature available to customers only).
