Migrating to Database 12c Multitenant - New Opportunities To Get It Right!
1 like715 views
The document discusses a webinar led by Dan Morgan on migrating to Oracle Database 12c multi-tenant architecture, highlighting the benefits such as lower total cost of ownership, improved stability, security, and performance. It emphasizes the necessity of knowledge transfer and careful planning for successful implementation to gain tangible organizational benefits, rather than simply upgrading for the sake of a new version number. The session is aimed at IT management to better understand the achievement and advantages of this migration strategy.

- 14. The More Things Change
- 15. Reasons We Upgrade • Loss of vendor support • Loss of compa&bility • Leverage new feature • Regulatory and Governance requirements • Employee reten&on
- 16. Tradi&onal Upgrade Considera&ons • What is it going to cost? • How fast can we do it? • How much down &me will be required? • Are there compa&bility issues? • What is our fallback if the upgrade fails?
- 17. What We Miss When a new feature is included, at no cost, Oracle sales does not know it exists: Rarely are they discovered and implemented Edition Based Redefinition Predefined Inquiry Directives Online Data Comparison DBMS_COMPARISON Table Compression Save Exceptions PragmasBigfile Tablespaces Virtual Columns Hidden Columns Function-Based Indexes Pipelined Table Functions Block Change Tracking Setting Optimizer Statistics Copying Optimizer Statistics Native Compilation User Profiles Password Verify Function Consumer Groups Advanced Rewrite Online Object Redefinition Feature Usage Reports Automated Partition Maintenance Resumable Transactions Sparse Collections Distributed Trust Administration If you buy food today and throw it away next week ... you wasted your money If you licensed valuable technology but didn't use it ... Conditional Compilation If I taught a class tomorrow titled "Oracle New Features" and included nothing in the class that wasn't at least 10 years old almost no one in my seminar would know the difference.
- 18. What Never Materializes • Lower Total Cost of Ownership • Greater Stability • Improved Security • Improved Performance • Improved Systems Compa&bility
- 19. Why They Never Materializes • We focus is on implementa&on not planning • Our goal is a higher version number not on what, specifically, will be gained by the organiza&on • LiLle aLen&on on knowledge transfer
- 20. Focus
- 21. What 12c Mul&tenant Can Offer • Lower Total Cost of Ownership – You pay for Oracle licenses by cpu core – 50% u&liza&on = 50% of your investment wasted – Today, by default, essen&ally all of Oracle's customers are was&ng ~10% of their investment in storage array

- 26. What 12c Mul&tenant Can Offer • Greater Stability – The DBMS_RESOURCE_MANAGER package has been in the Oracle database since version 8.1.5 – Greatly enhanced func&onality in Database 12c – Resources can be priori&zed by • Database • Applica&on • User
- 27. What 12c Mul&tenant Can Offer • Improved Security – Unified Audit Policies – New Security Creden&als – Common Users and Common Roles – Secure Provisioning from Seed Databases – New Data Masking Technology
- 28. What 12c Mul&tenant Can Offer • Improved Performance – Superior op&mizer algorithms – Superior SQL rewrite capabili&es – Improved resource management
- 29. What 12c Mul&tenant Can Offer • Improved CompaCbility – SQL Transla&on Profiles
- 30. Planning To achieve benefits you must: 1. Transfer knowledge to your team 2. Iden&fy what has value 3. Deploy with a focus on quan&fiable business benefits Some things cannot be done in a 2 week sprint
- 31. Summary • During the next 24 months most of you will upgrade to Database 12cR1 • If you do not leverage the advantages in the new architecture you may get liLle more for your effort other than a new version number
