From an architectural point of view, the LIXA project adopts an original approach: an Application Program links the LIXA client library and embeds the Transaction Manager logic. Every Application Program instance runs its own Transaction Manager instance and every Transaction Manager instance uses the LIXA server daemon to save and retrieve the state of the managed transactions. LIXA project was designed to allow massive parallelism and embedding at the same time: the parallelism is necessary to support high volume workloads while the embeddable property is necessary to avoid conflicts with the process and thread management feature of any Transaction Monitors.

LIXA architecture when used in conjunction with XTA is explained in Chapter 8, Developing Application Programs using XTA (XA Transaction API) interface.

Generic LIXA architecture is explained in Chapter 3, Configuration
