Short for transaction processing monitor, a program that monitors a transaction as it passes from one stage in a process to another. The TP monitor's purpose is to ensure that the transaction processes completely or, if an error occurs, to take appropriate actions.

TP monitors are especially important in three-tier architectures that employ load balancing because a transaction may be forwarded to any of several servers. In fact, many TP monitors handle all the load balancing operations, forwarding transactions to different servers based on their availability

TP Monitor位于客户机和数据库服务器之间，采用三层或多层模型。客户通过TransactionRPC(TRPC)机制在TPMonitor中调用事务，TPMonitor运行事务来连接数据库，并将处理结果返回给客户端。TPMonitor提供一系列服务，如应用管理、管理控制和应用之间消息传递等。常见的属性包括全局事务协调、分布式两阶段提交、资源管理器支持、协调故障恢复、高可用性、安全性和网络负载平衡等。
