What is a TP monitor, and why do I need one?
Generally speaking, a TP monitor is software that brings the benefits of resource management to the distributed computing environment. Applications comprised of many services and distributed across many servers can be managed from a graphical user interface, even during run time. A TP monitor that supports a two-phase commit protocol ensures the atomicity, consistency, isolation, and durability (ACID) properties of all transactions, even across different database management systems. Transaction IDs and context are sent between applications. TP monitors handle distributed transaction processing, inter-application messaging, and other enterprisewide application services. TP monitor software enables applications to encompass heterogeneous databases as well as non-DBMS data. For more details about transaction processing, two-phase commit protocols, and related topics, see one of the many texts available on the topic.
