What Is Transaction Processing Monitor (TPM)?

It doesn't matter if your application is single-threaded or multi-threaded—you need to know that every transaction goes through every step in its process with no errors. That's where the Transaction Processing Monitor comes in. It monitors each transaction from one stage to the next, ensuring that each completes successfully; if not, or if an error occurs, the TM Monitor takes the appropriate action. The TM Monitor is a gatekeeper for transactions, ensuring they don't get lost in cyberspace and never make it to their intended recipient. A TPM's main purpose/objective is to allow resource sharing and assure optimal use of the resources by applications. Transaction processing monitors are most commonly used in enterprise resource planning systems and ERP. However, they can also use them in other business areas, such as supply chain management systems, where sharing resources is critical. In the case of transaction processing monitors in ERP systems, monitoring transactions can help prevent financial losses to the organization. As undertaking resource planning systems are designed to control the flow of material and information within the enterprise, they can also use transaction processing monitors to manage the flow of sensitive information to protect the venture from unauthorized access. TPM is the "ghost" of your business transactions. It's a process that runs behind the scenes, ensuring that each transaction goes off without a hitch. TPM handles all load balancing in a multi-tier architecture. When processes run on different platforms, and a given transaction may be forwarded to several servers, the TPM handles all load balancing. After completing each transaction, it can process another without being influenced by the prior transaction. In other words, the TPM model essentially is stateless—it doesn't keep track of anything else except what's happening right now and what needs to happen next!
