    1. 1. Contents  Introduction  Pluggable & Container Database  Database Cloud & Consolidation Architectures  New Multitenant Architecture  Managing Shared Resources  Manage Many Databases as One
    2. 2. Introduction  Oracle announced general availability of Oracle Database 12c on June 25, 2013.  Oracle Database 12c introduces a new multitenant architecture that makes it easy to deploy and manage database clouds.  Oracle Database 12c provide private and public cloud deployments for the users.
    3. 3. Oracle 12c Database Editions  Oracle Database Standard Edition One  Oracle Database Standard Edition  Oracle Database Enterprise Edition
    4. 4. Oracle Database Options  Data Warehousing  High Availability  Management  Multitenant  Security  Storage Management
    5. 5. Pluggable Database (PDB)
    6. 6. Container Database (CDB) Database Link  The Pluggable Databases architecture can currently support up to 252 PDBs in a single CDB Database.  You can utilize Database Links between PDBs and between PDBs and non-CDB databases.
    7. 7. Database Cloud & Consolidation Architectures Virtual Machines Share servers with “VM isolation” Multiple DB Instances NEW DB 12c Multitenant Share servers and OS with “DB Instance Isolation” Share servers, OS and database with “Pluggable DB Isolation”
    8. 8. The need for Database Consolidation Why…?  Customers have 100s or 1000s of databases across their enterprise.  They want to lower costs by operating these databases on a centrally managed platform.  With only hardware consolidation, each database has an overhead, that prevents 100s of database from being placed on the same physical server.
    9. 9. Database Consolidation Requirements  No change to applications  No performance degradation  Centralized resource management  Simplify patching and upgrades ERP CRM BI DW
    10. 10. Oracle Database Architecture Each Databases requires memory, processes and database files System Resources
    11. 11. New Multitenant Architecture Memory and processes required at container level only System Resources
    12. 12. New Multitenant Architecture Memory and processes are shared and managed at container level System Resources
    13. 13. Managing Shared Resources Resource management Low Priority Medium Priority High Priority
    14. 14. Manage Many Databases as One Backup databases as one, recover at pluggable database Level One Backup Point-in-time recovery at pluggable database level
    15. 15. Manage Many Databases as One One standby database covers all pluggable databases
    16. 16. Simplified Patching Apply changes once, all pluggable databases updated Upgrade in-place
    17. 17. Simplified Upgrades Flexible choice when patching & upgrading databases
    18. 18. Creating Databases for Test & Development Fast, flexible copy and snapshot of pluggable databases
    19. 19. Benefits of Multitenant Architecture  Reduced TCO  Administrative costs  Operational costs  Data Center costs  Storage costs ERP CRM  Improved.. BI  Resource utilization DW  Manageability  Service Management
    20. 20. Conclusion  A new option for Oracle Database 12c, Oracle Multitenant helps customers reduce IT costs by simplifying consolidation, provisioning, upgrades, and more.
