  5. Project Goals (Business) • Move all business applications from RISC platform to Linux • Plan for future growth and scalability • Cost savings in terms of licensing and hardware • Rapid deployment • Save $$$’s • OM BPR • Review and update customisations

  6. Project Goals (Technical) • Standardize the installation of Oracle Applications 11.5.9 across 4 global installations in Electronic Arts • Upgrade to Oracle 11.5.9 e-business suite of products • Transition to e-business suite running on Linux RAC • Along with the upgrade • Produce a common and extensible hardware environment • That meets EA’s user and performance criteria, currently and into the future • Introduce a hardware and software architecture that would permit both scaling of capacity and continuous operations • The upgrade and platform transition, including user testing must be accomplished inside of 130 hours

  7. Fact sheet • Organizations, 1 in US, 21 in EU • Languages, 1 in US, 4 in EU • Database size, 200Gb in US, 350 in EU • Users, 175 in US, 350 in EU • Transaction volumes • 9000 order lines booked per day • 30000 picking line details per day • 10000 concurrent requests per day • Boundary systems, 15 in US, 25 in EU • Customizations, 1000 each in US and EU • Dual on-shore / off-shore delivery model

  8. Hardware Architecture & Scaling Plan • Dell was selected as the vendor of choice at EA for world wide deployment of Oracle 11.5.9 • RedHat 2.1 was the operating system at all tiers of the architecture • “Multi-node” & “Multi-tier” • Combination of both local storage and SAN storage • Intelligently deployed to get the highest performance and greatest economy from Oracle Applications • Hardware load balanced Oracle Applications servers • Easily configured and robustly implemented. • Dual concurrent process servers • Assuring rapid process completion • Confident & continuous operations, deployed with PCP (parallel concurrent processing) • Dual RAC nodes

  9. 11i Linux / RAC Architecture

  10. App 1 CM 1 DB Node1 App 2 CM 2 DB Node2 11i Linux / RAC Architecture Load Balancer RAC Database Datafiles

  11. Upgrade Process - Overview • Source • Oracle Applications Release 11.03 with 8i DB running on HPUX • Single Node Configuration • 8 Processors at 575 MHz Speed • Target • Oracle e-Business Suite Release 11.5.9 • 2 Application Servers (H/W Load Balance) • 2 Concurrent Manager Servers with PCP Configuration • 2 RAC Load Balanced DB Nodes • Upgrade Starts With • Single Node RISC Server Running 11.03 • One Intel Linux Application Server • One Linux CM Server • One Linux DB Server

  12. Upgrade Process - Overview

  13. Oracle 11.0.3 8.1.7.3 Oracle 11.5.9 9.2.0.4 CM 1 DB Node2 DB Node1 App 1 CM 2 CM 1 App 2 App 1 Upgrade Process - Overview Cat 1-3 Auto Upgrade Auto Patch 11.5.9 CM2 Cat 4-6 Export Import Index Build RAC (DB2) App2 CM2 Oracle Apps 11i – Linux Apps/CM, HP DB Export & Import HP Server Single-node Linux 11.5.9 Linux 11.5.9

  14. Upgrade Process - Overview • Customized Oracle Upgrade Approach • Heterogeneous upgrade approach • Admin node running on Linux and DB node running on RISC server • Pre upgrade steps • Rapid install (Linux application server & CM server) • 9i DB Installation (Linux DB server) • Category 1, 2 and 3 steps • Perform all relevant category steps on RISC server running 11.03 • Gather schema statistics (30%) • Backup applications • Auto Upgrade • Admin node running on Linux and DB node running on RISC server • Batch size of 10000 & max workers of 20 • Backup applications • Auto Patch • Gather schema statistics (30%) • Backup applications

  15. Upgrade Process - Overview • Customized Oracle Upgrade Approach • Patch the applications • Apply consolidated update patch 2 • Apply one off patches • Category 4, 5 and 6 steps • Perform all relevant category steps • Apply customizations (if any) • Apply conversions (if any) • e-Business suite functioning with • Linux application server • Linux CM server • RISC DB server

  16. Upgrade Process - Overview • Customized Oracle Upgrade Approach • Export source DB • Apply applications consolidated export import patch (2981815 ) for 9i on SOURCE admin node. • Direct path full DB export • Import DB • Apply patch # 2873456 • Point your APPL_TOP to the 9i DB • Full system import or • Two phased import process where structure is imported first and data is subsequently imported. • Index builds are always last with either of the import choice • Post import activities • Gather schema statistics • Modify TNS names on Admin and CM nodes to point to 9i DB

  17. Upgrade Process - Overview • Customized Oracle Upgrade Approach • Converting to RAC DB • Modify ORACM configuration file • Follow Metalink documentation • Adding Second Application Server • Change the application server name to load balancer • Review H/W load balancer setup • TAR and UNTAR the APPL_TOP onto second node • Adding Second CM Server • Create second CM node by cloning from first CM • Setup Internal Monitor (ICM) • Define Primary & Secondary nodes for all Concurrent Managers • Define the transaction managers for all the instances in RAC cluster

  18. Upgrade Takeaways • Total Production downtime of 98 hours • Perform as many iterations as possible • 12 practice iterations were performed • Impact of hardware • Import process needs lot of attention • Impact of Orgs and Languages • Be generous with your instance planning – you will need them! • Refine backup methodology, to provide total database backups as rapidly as technically achievable • Perform Validate APPS Schema script on production regularly and fix the issues • Make time for high quality testing of both standard and custom Oracle Applications code • 20 One off patches applied on consolidated patch 2 • Perform load test and regression testing The Upgrade – Category 0 The Upgrade – Category 0

  19. Infrastructure Issues • Instance Planning • Differences from Traditional Unix to Linux platforms • Impact of server numbers • Don’t forget the disk space! • Important considerations • Data Archiving • Getting it all to work! e.g. load balancing, DNS etc. • Log/out files, UTL, FTP • Individual server memory footprint

  20. Global Team Tactics • Global Project technical, functional and support teams • Managing communication • Coping with time zones • Make it work to your advantage • Sharing of knowledge • Client/Vendor sharing • Examples of success

  21. Agenda Revisited • Who we are • Description of the Goals • Hardware Architecture & Scaling Plan • 11i Linux / RAC Architecture • Upgrade Process Overview • Upgrade Takeaways • Infrastructure Issues • Global Team Tactics • Questions & Answers
