Explain how a TP Monitor manages memory and processor resources more effectively than a typical operating system?

Answer 1

An application server permits a large number of users to execute applications using a minimum of system resources. An application server can be extended to allow coordinated transactions to be invoked from applications executed by the application server. This transaction coordination is generally known as a Transaction Processing (TP) monitor. A TP monitor works in conjunction with an application server.

A transaction can be thought of as a routine event, usually a request for service, in running the day-to-day operations of an organization. The orderly processing of transactions is the type of work for which TP monitors were designed.

Transaction processing

Every organization has rules and procedures that describe how it is supposed to operate. The user applications which implement these rules can be called business logic. The transactions these business applications execute are often referred to as Transaction Processing or Online Transaction Processing (OLTP).

The key characteristics of commercial OLTP are:

Many Users

It is common for transaction processing to be used by the majority of the people in an organization, since so many people affect the current state of the business.

Repetitive

Most interactions with the computer tend to be the same process executed over and over again. For example, entering an order or processing payments are used many times every day.

Short Interactions

Most interactions that people in the organization have with the transaction processing system are short in duration.

Shared Data

Since data represents the state of the organization, there can only be a single copy of the data.

Data Integrity

The data must represent the current state of the organization, and must be internally consistent. For example, every order must be associated with a customer record.
