3. Agenda Why Linux? Trends in the Linux Marketplace Migrations Project Considerations Project requirements –Resources and project timeline Linux Platform Migration Utility Roadmap to two-step migration TUSC working with Linux

4. Why Linux? Cost Performance Security Stability

5. Trends in the Linux Marketplace Increased market share Dominant Oracle database presence Sensible solution for Oracle Applications

6. Increased market share Total Server Market : $53B Unix Sales: $19.4B – 6% Decrease Linux Sales: $3.23B – 47% Increase TechWeb News, June 17, 2004

7. Dominant Oracle database presence Oracle has 32.6 percent RDBMS market share ($2.31B) Linux RDBMS has 4.2 percent Oracle has 69% of the Linux RDBMS market –Up 360% –Oracle 9i RAC Clustering a big factor IBM Linux has 28.5% of the Linux RDBMS market CRN, May 26, 2004

8. Sensible solution for Oracle Applications High availability and scalability Substantially reduced cost Run on Intel-based hardware Proven technology for E-Business Suite Proven technology for 9i Real Application Clusters Easy migration with the Linux Platform Migration Utility Oracle Corporation, 2004

9. Migrations Project Considerations –Certified OS and Software versions –Pre-requisite Patching –Create and Upload Manifest –Upgrade Dot Release and Migrate Upgrades Applications; New functionality Users need to test at least once for migration and upgrade

10. Migrations Project Considerations –Migrate Users need to test migration Future upgrade requires additional testing –Production Cutover Downtime –Post Go-Live Support –Operating System Support Training vs. Outsourcing

11. Project requirements Timeline: –Database migration to Linux –Applications migration to Linux Resource requirements: –Database Administrator (full time) –Testing Team (functional and technical resources)

12. Linux Platform Migration Utility Provides a way to quickly move an existing Oracle Applications Includes Technology Stack Upgrade to 11.5.10 Retains exact application patch level therefore no APPL_TOP/Database synchronization is necessary Retains many customizations

13. Migrate Oracle Applications to Release 11i High level steps: –Apply Migration utility patch –Generate and upload manifest –Copy source files and directories to Linux –Install 11.5.10 Tech Stack –Configure applications on Linux Documentation: Metalink Note 238276.1

14. High level steps: –Export source Release 11i database (any OS) –Prepare a target Release 11i database (Linux) –Import target Release 11i database (Linux) –Update imported Release 11i database (Linux) Documentation: Metalink Note 230627.1 Migrate database to Linux

15. TUSC working with Linux Supported an Online E-Commerce site a 4 node 10g RAC cluster on RHEL 3. Upgraded standalone / Windows / 8i to 9i RAC on Linux RH Enterprise 3.0. (Performance improved quite a bit) 9204/RAC database on Red Hat ES 2.0. Upgrade from 8.1.7 on SCO to 9.2.x on Red hat ES 2.0. Conversion for ERP from 8.1.7/Win32 to 10g on Red Hat 3.0. Moving a 3-node RHEL RAC to 6-node.

16. TUSC working with Linux 2 articles on OTN on installing/configuring 10g single instance and 10g RAC on every Linux version supported by Oracle. 3 presentations on the RAC SIG website. TUSC RAC class uses a two-node Linux cluster using a single firewire shared drive for storage. It runs both 9.2.0.4 and 10g RAC on the same cluster without problems. Of course, it's not meant to perform well, just to demonstrate functionality.
