Understanding PeopleSoft Analytic Calculation Engine Chapter 2

• Map individual record fields to data cubes and dimensions within the cube collections.

Analytic Type

Both PeopleSoft Analytic Calculation Engine and PeopleSoft Optimization Framework use analytic types. Use

PeopleSoft Application Designer to create an analytic type definition, which defines the caching behavior of

the records that the analytic model uses, specifies the records that are accessible b y all end users, and specifies

the records that are only accessible by certain users for what-if scenario forecasting.

See C

hapter 12, “Understanding the Relationship of Analytic Types to Analytic Models,” Purpose of

Analytic Type Definitions, page 201 and Enterprise PeopleTools 8.49 PeopleBook: PeopleSoft Optimization

Framework, “Designing Analytic Type Definitions”.

Analytic Ins

tances

Analytic instances are runtime instances of analytic types that are loaded into analytic se rver instances

by means of the AnalyticInstance class Load method. The AnalyticInstance class is one of the Analytic

Calculation Engine classes. To view and edit analytic model data, an end user selects an analytic instance ID

within an application’s PeopleSoft Pure Internet Architecture pages.

Analytic Calculation Engines

Analytic cal

culation engines run inside analytic server instances. They calculate analytic instance data by

using the re

lationships and rules that are defined in the analytic model.

Analytic Server Instances

When used with PeopleSoft Analytic Calculation Engine, a na l ytic server instances are processes in the

application server domain that contain and run analytic instances and analytic calculation engines. When a

user selects an analytic instance ID within an application, the system generates one analytic calculation engine

and one analytic server instance. One analytic server instance can contain one and only one analytic instance,

and one and only one analytic calculation engine. All three of these components—plus the application

server—exist in one application server domain. An application server can only communicate with analytic

server instances that exist in the same application server domain as the application server. For this reason,

a PeopleSoft application that exists in one application server domain cannot communicate with an analytic

model that exists in a different application server domain.

The PSANAL

YTICSRV table contains a row that provides information about each analytic server instance

that is ru

nning within an application server domain. You administer analytic server instances by using the

Summary a

nd Servers pages that display the data from the PSANALYTICSRV table.

See Enterprise PeopleTools 8.49 PeopleBook: System and Serv er Administration, “Managing Analytic

Servers,” Administering Analytic Servers.

Analytic Calculation Engine Classes

You use t h

e Analytic Calculation Engine classes for all runtime operations between PeopleSoft applications

and analy

tic calculation engines. Use the Analytic Calculation Engine classes to either retrieve or specify

data in an

instance of an analytic model loaded into the system, and also to calculate (or recalc ulate) data

cube val

ues. The Analytic Calculation Engine classes run on the application server and use Tuxedo service

request

s to communicate with analytic server instances.

The Analytic Calculation Engine classes contain the AnalyticInstance classes, which are used by PeopleSoft

Analytic Calculation Engine and PeopleSoft Optimization Framework to manipulate analytic instance

definitions with PeopleCode. Use the AnalyticInstance classes to manipulate analytic instance definitions

at runtime.
