Focus

Generic Oracle Applications concepts Not tied to specific installation(s) Provide background for how Apps works Help with support tasks in general Technical

– how it works– how to make it go



What is Oracle Applications? Oracle Applications is:

– Also called Oracle E-Business Suite (EBS)– Huge, takes 100Gb just to install

Doesn’t include database data or staging area– Multiple business applications– System of record

Can’t remove users for example– Built on top of Oracle database (RDBMS)– A mess, you’ll never control it– Great job security

You don’t have to be crazy, but you soon will be…



Why Use Oracle Applications?

Businesses have (or had) – Multiple business application systems

Peoplesoft for HR Siebel for CRM (Customer management) Other apps for orders, manufacturing etc.

ERP (Enterprise Resource Planning)– Provide single system for all business apps– One system of record

Latest trend is a single global instance



What is ERP?

From wikipedia

Enterprise Resource Planning (ERP) systems attempt to integrate all data and processes of an organization into a unified system. A typical ERP system will use multiple components of computer software and hardware to achieve the integration. A key ingredient of most ERP systems is the use of a unified database to store data for the various system modules.



Oracle EBS Products

Each business application is a ‘product’

Oracle Assets Oracle General Ledger Oracle Payables Oracle Receivables Oracle Cash Management Oracle Bills of Material Oracle Capacity Oracle CRM Oracle Advanced Planning & Scheduling Oracle Purchasing Oracle Business Intelligence Oracle Engineering

Oracle HRMS Oracle Inventory Oracle MRP Oracle Order Entry Oracle Order Fulfillment Oracle Payroll Oracle Project Costing Oracle Project Billing Oracle Purchasing Oracle TMS Oracle Work in Process. Oracle Process manufacturing.



Oracle Applications Modules

Business applications– Referred to as module or product– Have two or three letter short names– General Ledger – GL– Accounts Receivable – AR– Advanced Pricing – QP– Configurator – CZ– Each has a database schema

Db schema name is application short name Db user for each application Db user APPS has access to all applications schemas



Oracle Applications

Older applications– Oracle calls them “Professional”– Based on Oracle Forms– Need JDK plugin to render forms

Newer applications– Oracle calls them “Self-Service”– Browser based

Eventually, all apps will be browser based



Technical vs Functional Person

No one knows all of Oracle Applications– Don’t say you do in an interview

Technical– Database, configuration, patching– Infrastructure– How to stop/start the applications tier processes?

Functional– Business process of a product/module– How does General Ledger handle period close?



History of Oracle Applications

Major Versions– 10.7

Character based client, no java, database 7.3.4

– 11.0.x GUI client, no java in database (8.0.5)

– 11.5.x (known as 11i) GUI client, java, database 8.1.6 thru 10g

– 12.x Latest version, java, database 10g/11g



History of Oracle Applications

Versions, number of products, number of objects– 10.7 40 products, 25,000 objects– 11.0.x 50 products, 30,000 objects– 11.5.5 161 products, 200,000 objects (first version of 11i)– 11.5.6 175 products, 240,000 objects– 11.5.7 179 products, 280,000 objects– 11.5.8 191 products, 278,000 objects– 11.5.9 191 products, 308,000 objects– 11.5.10 209 products, 268,000 objects– 11.5.10.2 211 products, 284,000 objects

From Installing, Upgrading and Maintaining Oracle E-Business Suite Applications 11.5.10+, Barbara Matthews et al



Where Do You Fit In?

11.5.10.2 -- 211 products, 284,000 objects Each product is a business application All products need patching

– Patching becomes a full-time job

Each product has new features Many products are shared

– Multiple dependencies– Order management linked to General Ledger



11i Architecture

At a high level we have Tiers– (you will cry a lot while you support them)

Desktop Tier– User client

Application Tier– Lots of servers, more later

Database Tier– Oracle RDBMS

Desktop Tier Browser

– HTML for newer self-service applications– Java applet for forms-based applications– Must not block popup windows

Applet– Forms client applet– Requires JVM to run inside browser– Oracle JVM implemented as browser plug-in

JInitiator Must have specific plug-in/JRE version

Configured at installation or through patching Mozilla versus Firefox



Application Tier

Multiple servers– Web Server

Based on Apache

– Forms server– Reports server– Concurrent Processing server– Admin server– Discoverer server

optional



Application Tier

For each of these servers– start/stop scripts– Log files– Configuration files– Software patches– Version information– Troubleshooting procedures– Bugs (no! really?)



Application Tier Servers

Web server– Must be running to serve

Web-based self-service applications Oracle Applications login screen (web page)

Forms server– Must be running to serve forms-based applications

Reports server– Handles user requests for reports– Retrieves data from db and formats report– Sends report output to client browser




Concurrent Processing server– Glorified batch processing– Process long running queries in background– Schedule jobs

Work shifts Conflict resolution

– Concurrent requests Execute concurrent programs Executed by concurrent managers



Types of Concurrent Managers

Internal concurrent manager– Controls all other concurrent managers

Standard concurrent manager– Process most concurrent requests

Specialized concurrent manager– Modified for special needs– Assigned to selected concurrent programs




Admin server– Not really a server– Collection of Applications DBA tools

Hence the AD in the names of the utilities– Adadmin

Set maintenance mode required for patching Recompile applications database schemas

– Adpatch Apply applications patches

– Adconfig Apply configuration changes to multiple products




Discoverer server (isn’t Disco dead?)– Part of Oracle Application Server– Part of Oracle business intelligence (BI)– Hides complexity of database

Maps db schemas to business user terms

– Supports ad-hoc query reporting Users can bring system to a crawl…

– Predefined reports Standardize reporting across organization



Database Tier

Oracle database– APPS database user

Can access all product data Doesn’t own product tables, indexes, sequences Has grants synonyms to product schemas

– Applications users Separate and distinct from database users FND_USER table, DBA_USERS table Change passwords carefully



Applications Database

Grants and synonyms

APPS

APPS database user has grants synonyms to database schemas APPLSYS, GL, INV, AP and all other products



Applications Db Tablespaces

Before 11.5.10– Each product had two tablespaces

Tables, indexes

– 200 products, 400 tablespaces

As of 11.5.10– Oracle Applications Tablespace Model (OATM)– 12 tablespaces total



Applications Db Tablespaces

APPS_TS_TX_DATA -- transactional dataAPPS_TS_TX_IDX – transactional indexesAPPS_TS_SEED – seed data, reference dataAPPS_TS_INTERFACE – interface tablesAPPS_TS_SUMMARY – summary objectsAPPS_TS_NOLOGGING – temporary objectsAPPS_TS_QUEUES – advanced queuingAPPS_TS_MEDIA – graphics, spatial dataAPPS_TS_ARCHIVE – obsolete tables for compatibilityUNDO – undo tablespaceTEMP – temporary tablespaceSYSTEM – system tablespace



Tiers and Servers

Single tier installation– App tier servers and database on single machine

Multiple tier installation– Database on one machine– App tier servers on one or more machines– Load balancing– HA– More complicated



Traditionally

Concurrent processing, db on same server– Concurrent processing uses database heavily– Reduce network latency

Other servers on apps tier server– May have multiple apps tiers for load balancing

Today– Network performance is better– Apps tier, db tier servers in datacenter– Concurrent processing can be on apps tier server

Only need to patch once



What Does It Look Like?

Login to Oracle Applications– See user responsibilities– Select responsibility– Bring up

Form based application

Users form Web based application
