  1. Fall 2001 OAUGSan Diego Release 11i Upgrade Workshop November 2001

  2. Agenda • Introductions and Information • Overview of Upgrade Project • Question and Answer Panel • Breakout Sessions

  3. Our Facilitation Team • John Stouffer - Solution Beacon • Alicia Hoekstra – KPMG • Eric Riegelman – Stonebridge • Donna Flowers – Stonebridge • Mark Clark - O2Works LLC

  4. Upgrades – Easy to Understand • Why Upgrade? • What Happens During an Upgrade? • Why Such a Big Deal? • Overview of an Approach to Managing Upgrades for Success • What Resources are needed and when • What can be expected?

  5. Why Upgrade At All? • Support Issues and Maintenance Issues • Performance Improvements • New Applications Available • Architecture Changes allow leverage of Intra/Extra Nets • New Functionality provided in Existing Modules • New AOL Features like Workflow, Self Service Layers • Critical Features Needed

  6. 30,000 Feet – The Code • Standard Code Supplied by Oracle • New Tables and other objects created • Changes made to EXISTING tables and data to conform to 11i standards • New Forms and Reports are installed for use by End Users

  7. 20,000 Feet – The Path • Pre- Upgrade Steps – Users and Tech Team • Automated Steps – Tech Team – Thousand of Scripts will run Automatically and be monitored • Post Upgrade Steps – Users and Tech Team

  8. 10,000 Feet – The System • Some New Hardware • Some New Operating System • New Database Version • Lay Down Upgrade Code • New Executable Code • Pre, During, and Post Upgrade • Go Live

  9. 5,000 Feet – Milestones • Copy of Production Database – no users in the system • On a Module by Module Basis – Category One – Category Three Steps and Programs must be run – and Any Corrections Made.. Can take Many Hours. • Auto Upgrade Process Runs – Thousands and Thousands of Scrips Run – each must complete successfully before Proceeding – WILL take a LONG Time

  10. 5,000 Feet (Con’t) • Additionally Patching to fix known Issues – more scripts that must all succeed without error. • Category Four, Five and Six Post Upgrade Steps – All must Complete Successfully – Can take many Hours • Additional Patching – Can take Many Hours • Reapply Customizations, Enhancements

  11. Why Such A Big Deal? • Uncertain Downtime – Large Number of Variables. • Uncertainty regarding “Clean” Data Before the Upgrade • Uncertainty on Oracle Standard Code being 100% First Time • Uncertainty on New Functions “Fitting” ELDEC Business Requirements • Uncertainty Around Re-Integration (and Need for) Customizations/Enhancements

  12. GOAL: Remove all uncertainty • Test Upgrade One– Round One – Identify, Understand and Measure – Post Mortem • Test Upgrade Two – Review, Note Issues, and “Squeeze” Downtime – Reapply Customizations. • Make System Available for Testing • Fix Bugs, Issues, and Gaps • Optional Additional Rounds • Create Production Cutover Plan • Production Cutover

  13. Our Approach • Establish Safe Environment for Testing • Read and Re-Read the Upgrade Manual for EACH Module and Document Required Steps • Assemble List of Customizations • Check with Support for Steps where documentation is Unclear • Use Upgrade Assistant to Track To Do List • Take A Snapshot of Production

  14. Our Approach • Per MODULE - Assign Resources to Understand and Execute Category One through Category Three Steps – and Designated Resource going forward. • Document the time required for Each Step. • Note those steps that can be done Well Before – Even in Production (cleanup)

  15. Approach Continued • When complete – Take a Baseline Backup • Run AutoUpgrade – Start Timing • Capture Timing on Long Running Jobs • Note Any jobs that break, get restarted, and any Fixes – DOCUMENT • When Complete – take another Backup • Begin Post Upgrade Steps – Again – Assign Champions to do this. Capture Timings

  16. Approach Continued • Take Post –Post-Upgrade Backup • Apply Additional Patches- Capture Timings • Backup • Verify Applications • Round One – Post Mortem • Turn System Over to Developers to Begin Design Upgrades for Customizations

  17. Customizations • Identify Them All • Pre-Analysis (get rid of some) • After Round One – Design Re-Integration • Build and Unit Test • After Round Two – Install and System Test • Review and Adjust • Load Test • Incorporate into Overall Production Plan

  18. Approach in Summary - • Read and Plan • Execute and Time • Multiple Backups • Squeeze Downtime Window • Repeat and Integrate Customization – Do for “Timing” • Test Extensively • Readjust Plan • Communication and Production Cutover

  19. What Resources are Needed and When? • Technical Resources – • DBA – Planning, Auto-Upgrade, Patching, Support and more Patching • Developers – Catalog and Design Customizations • Tech Leads – Lead Team of Developers per and Across Areas • Tech Project Managers – Planning and Execution

  20. Resources and When • Functional – • Project Lead – Planning, Execution • Business Analysts – New Features, Gap Analysis, Propose Customizations and Ex-Customizations • Testing – Application Verification, System Testing • Gap Identification – Work with Developers on New Design, Build and Test

  21. What can you Expect? • Serious Project – Just like Implementation • Drain on Resources • Cooperation Across Departments • Communication on Status • Numerous “Speed Bumps” • New User Interface • Lots of time with Oracle Support

  22. Typical Upgrade Steps • System Review and Initial Project Planning – 3-8 days (Production) • System Stabilization (Production) and Detailed Project Planning – Environment/Resource Dependent • Test Upgrade and Support – 5-7+ days (use a Complete/Current Copy of Production) • Application Testing and Support – Environment/Resource Dependent • Extensions Re-Development and Remediation – Environment/Resource Dependent • Training – Environment/Resource Dependent • System Integration Testing – Environment/Resource Dependent • Production Upgrade and Support – 3+ days

  23. Upgrade Timeline – One Example System Review/Project Planning System Stabilization Test Upgrades & Support Application Testing Redevelopment Team Training User Training Integration Testing Production Upgrade
