What isMicrosoft Transaction Server

Microsoft Transaction Server (MTS) is a TP monitor for Windows NT servers that supports transaction-based applications on LANs, intranets, and the Internet. It acts as an intermediary between the client and database server in the middle layer of a multi-tier system, making it an essential part of a scalable and distributed architecture.

MTS is based on Microsoft’s component software architecture (COM) and hosts business logic that is developed as ActiveX Server Components. After a component is built for a single user, MTS scales the process for numerous users. The server components can use ADO, OLE DB, or ODBC interfaces to retrieve the necessary data.

One of the key features of MTS is its support for two-phase commit, which is enabled by its integrated Distributed Transaction Coordinator (DTC). This ensures that transactions are either committed or aborted so that data consistency is maintained and errors are handled accordingly.

It’s important to note that MTS is not a standalone component in Windows 2000 but is instead a part of the operating system. This means that it operates seamlessly with other Windows 2000 services and can be easily configured and managed through the Microsoft Management Console (MMC).


What is a TP monitor?

A TP monitor is a software application that manages and monitors transactions in a distributed system. It ensures that transactions occur reliably and efficiently, usually by providing features such as transaction tracking, connection pooling, and load balancing.

What is a multi-tier architecture?

A multi-tier architecture is a software system that’s divided into layers or tiers, each with a specific role and responsibility. The tiers commonly include a presentation tier (for user interaction), an application tier (for business logic), and a data tier (for data storage and retrieval). This type of architecture allows for greater scalability, modularity, and flexibility.


Microsoft Transaction Server (MTS) is a powerful TP monitor that plays a crucial role in multi-tier applications. Its support for distributed transactions and its scalability make it an effective tool for building enterprise-level systems that can handle large volumes of users and data. Additionally, since it’s a part of the Windows 2000 operating system, it’s easy to configure and manage using familiar tools like the Microsoft Management Console (MMC).
