Application Engine Overview

What is it? Simply, a graphical development tool for high-

volume, batch processing

Offered as an alternative to COBOL or SQR

(for non-report processing)

First introduced in Release 5

AE has become incorporated into many

products, some use AE exclusively forbatch processing


4/25

By the Numbers

PeopleSoft 8.0 381 AE programs in HRMS

474 AE programs in Financials/Supply Chain

144 AE programs in Enterprise Performance

Management 12,000 AE Sections

PeopleSoft 7.5 56 AE programs in HRMS

132 AE programs in Financials/Supply Chain


5/25

AE Architecture Prior to 8.0

AE built as an application usingPeopleTools

Design timeAE application is launched under the Tools -

Application Engine Menu

AE program definitions are defined usingstandard application panels

Runtime Implemented in COBOL

Limited to the same functionality as COBOLprograms


6/25

Challenges for 8 and Beyond

Provide batch support for our XML-based internet integrationtechnologies

Continue to enhance features Provide a rich development environment

Runtime performance improvements

Leverage PeopleTools features


7/25

The Solution

Introducing the new Application Engine

Complete redesign of AE New design time tools

New runtime engine

Feature rich

Faster

UpgradableIntegrated

Open to the internet via XML

9/25

New Features

Meta-SQL New suite of Meta-SQL functions and variables

Fully leverage the data dictionary

Improved performance via programcaching Dramatic improvement in row-by-row

processing

File ProcessingMultiple state records


10/25

New Features

Parallel Processing Support Temporary tables are defined once and

expand many physical tables

%Table references for tables enables parallel

processing with no changes to source code Temporary tables (or a suite) are assigned to a

program

AE runtime program chooses an availableinstance and locks the tables until a successful

completion Tables can be released manually via process

monitor


11/25

New Features

Code sharing Program library feature

Marking sections Public

Code flexibility via the AESection ObjectAllows AE sections to be created inPeopleCode

Allows dynamic vs. static sections

Enhanced commit control Commit after x iterations of a loop


12/25

Internet Integration

PeopleCode within AE is the key tointegration

From AE PeopleCode, you can Publish an Application Message

Invoke a Component Interface

Invoke a Business Interlink

Read, write and convert files (XML, CSV orfixed)


13/25

AE Program Architecture

AE Program Basically the high level program definition

SECTIONS Each application is made up of one or

more SECTIONS

STEPS Each SECTION is made up of one or more

STEPS

STEP Actions Each STEP is made up of one or more

STEP ACTIONS


14/25

A Closer Look at Step Actions

An action is really a programstatement PeopleCode

SQL Do Select

Do When

Do While

Do Until Log Message

Multiple actions can be combinedwithin a step


15/25

AE Designer

AE is now integrated into the ApplicationDesigner

Operate on your entire application

Works like existing PeopleTools objectsAE programs can be added to projects

AE programs are available to theupgrade/compare facility


16/25

AE Designer

Leverage the Application Designercommon tools Cut/Copy/Paste

Printing Find in

AE program views Use filters to narrow scope of your

application The program flow view to visualize your

application in program execution order


17/25

SQL Objects

Three types of objects Standalone

AE

View Text

Common approach for re-using SQLstatements or fragments

Platform specific and effective datedSQL

Add SQL via the Application Designer

Add, modify or execute SQL viaPeo leCode


18/25

SQL Objects and AE

All AE SQL actions are stored as SQLobjects

Re-using standalone SQL objects via%SQL

Modify SQL objects in PeopleCode Use PeopleCode (online) to create or modify

SQL objects

Access those objects from AE using %SQL

AE program remains constant while the SQLdynamically changes


19/25

SQL Editor

Once a SQL action is defined, the SQLdesigner can be launched from the AEworkspace

SQL is formatted and validated at savetime

META SQL can be expanded in the outputwindow


20/25

PeopleCode Editor

Once a PeopleCode action is defined, thePeopleCode designer can be launchedfrom the AE workspace

PeopleCode is formatted and validated atsave time

All PeopleCode functions are availableexcept for user-interface related functions

internet-only functions


21/25

Transaction Control

Calling AE from PeopleCode Use the CallAppEngine PeopleCode

function

Can be executed in FieldChangePeopleCode and will be in a separate Unitof Work

Can be executed outside of FieldChangePeopleCode and will be in the same Unit

of Work

Calling Existing COBOL programs fromAE Called via RemoteCall function and will

execute in a separate Unit of Work


22/25

Conversion

AE program definitions are now stored innew tools tables

The PeopleTools upgrade process willconvert your existing AE programs to thenew format (for compare purposes)
