3.2. User-Defined Batch Server

The following sections of this document will provide additional detail about each of the layers in the Distributed System Architecture.

Table of Contents Previous Section Next Section Systems or Machines

An application or suite of applications that is currently running on a Mainframe System may be transferred to a single Distributed System (at the source code level). Once the transfer is complete the source code may be compiled and executed on the Distributed System.

The application data may be transferred to a Local Server, a User Machine or left in place and accessed on the Mainframe System.

Even though it is possible to transfer and execute the application on a single Distributed System this is the exception. A typical distributed configuration would consists of three (3) machines (or Systems). The first machine would provide a foundation for the application. The second machine would provide a foundation for a Data Base Management System. The third machine would provide the foundation for overall system security. Each of these machines may be a separate physical machine or a virtual machine.

Table of Contents Previous Section Next Section Application System

The Application System provides a foundation for a business application or suite of applications. This includes the hardware, an Operating System, sub-Systems and Third-Party Software.

1. Hardware
1.1. Server Machine

3.3. MS/SQL
3.4. Oracle
3.5. ODBC

Table of Contents Previous Section Next Section Security System

The Security System provides the foundation for overall system security. A typical configuration would use Windows Active Directory with an LDAP Interface.

Active Directory is a database based system that provides authentication, directory, policy, and other services in a Windows environment.

LDAP (Lightweight Directory Access Protocol) is an application protocol for querying and modifying items in directory service providers like Active Directory, which supports a form of LDAP.

Table of Contents Previous Section Next Section Servers and Sub-Systems

The following sub-Section of this document will focus on the Servers, sub-Systems and Third-Party Software required to support the application execution on a distributed platform.
