Question 2.
Describe a TP monitor environment. How can a TP monitor stop an operating system being overwhelmed?
A TP monitor is a Transaction Processing monitor. In a distributed client/server environment, a TP monitor provides integrity by ensuring that transactions do not get lost or damaged. It may be placed in a separate machine and used to balance the load between clients and various application servers and database servers. This ensures that one single server is not overwhelmed. It is also used to create a high availability system by switching a failed transaction to another machine. A TP monitor guarantees that all databases are updated from a single transaction.
