What are the OpeN/2 ComponentsWhat are the OpeN/2 Components

OpeN/2: Engine

OpeN/2: EFT

OpeN/2: Applications

OpeN/2: Engine

A platform designed to provide a distributedobject oriented processing environment for

the development of OLTP (On Line

Transaction Processing) applications.

OpeN/2: EFT

An online transaction processing (OLTP)

application designed to support electronic-based financial consumer transactions.

OpeN/2:EFT contains the common code for all

financial and retail applications and uses the

common code of the OpeN/2:Engine.

OpeN/2: Applications

The applications that sit on top of OpeN/2:EFT

contain the business logic needed to process

certain types of transactions. They use the

common code from both OpeN/2:EFT and the

OpeN/2:Engine.

Engine ConfigurationManagerA configuration program that

defines the components

necessary for On-Line

Transaction Processing

(OLTP) tooccur. It is the user

interface for the OpeN/2:

Engine.

Engine Command andControlAn interface designed to track

messages in the system, record

errors that have occurred in the

system, and monitor

applications for activity

Engine Message MapperAn interface that allows the

creation of message maps

used by an application. Thesemessage maps associate the

contents of a set of fields

contained in a linear record

format into a set of named

variables.

Blue Print SecurityAn interface that allows

administrators and developers to

limit the kinds ofoperations eachuser can perform on various

objects. This maintenance

application is provided to assist

in maintaining the security

system

What is the OpeN/2: Engine Database?What is the OpeN/2: Engine Database?

A database named config

is created on the database

server

The config database is

used to storeconfiguration and

operational data for the

OpeN/2 processes and

environment.

The database is created by

OpeN/2: Engine utilities

during installation.

What is Vertical Scaling?What is Vertical Scaling?

Vertical scaling is the process ofadding resources to a single server to

improve transaction throughput.

Two methods exist to scale vertically:

Additional applications can be added

to an existing node. This also

includes the ability to add worker

tasks to existing applications.

Second, an additional node can be

added to the server.

AccessibilityAccessibility

Open access to data

Since OpeN/2uses a relational database, the data is readily

available. Full access to the data depends upon the database

security that is in place for the particular user.

Leverage 3rd party software tools

The relational database used by OpeN/2 allows any third party

software tool that can access the database vendor to generate

reports and queries.
