Oracle Real Application Clusters 10g: The Fourth Generation Angelo Pruscino Oracle Corporation Session id: 40131

Agenda  The Generations  Key IT imperatives  Roadmap to Enterprise Grids  Where We Are Now – Oracle9i RAC HA and Scalability – Low Cost Clusters  Next Steps – Oracle RAC 10g Manageability “RAC for Everyone”

The Generations 1 Know Your Customer BI and CRM 2 Reach Your Customer Internet And e-Commerce 3 Consolidate Big SMP And Clusters 4 Be Adaptive Proactive AgileEnterpriseGrids

Key IT Imperatives  Highest Quality of Service – Maximum availability – Maximum scalability  Most Efficient Management – Do much more  Lowest Cost – With much less EnterpriseGrids

Roadmap Now Highest Quality Service Lowest Cost Oracle9i RAC HA & Scalability Low Cost Clusters RAC 10g For Everyone Most Efficient Management Adaptive Proactive Agile EnterpriseGrids

Oracle9 i RAC HA & Scalability  Full Cache Fusion – Cache-to-cache data shipping – Shared cache eliminates slow I/O – Enhanced IPC  Allows flexible and transparent deployment – Scale-up/Scale-out Users Shared Cache Clustered Database Servers Storage Area Network Mirrored Disk Subsystem Low Latency Interconnect VIA or Proprietary High Speed Switch or Interconnect Hub or Switch Fabric Centralized Management Console Cache Fusion

Next Steps: RAC 10g Manageability  Key part of much larger Oracle Database effort – Oracle9i -> reduced operational costs by half – The Oracle Database 10g -> reducing by another half  Advanced functionality that has been totally automated: – Rollback Segment Management – enables highly efficient support for mixed OLTP/DSS workloads (Oracle9i) – Backup & Recovery – provides mission critical protection from media failures and corruptions (Oracle9i) – Memory Buffer Management – key enabler of high performance and scalability (Oracle9i and Oracle Database10g) – Automatic Storage Management – automatically balances I/O across disks for maximum performance (Oracle Database 10g)

Next Steps: RAC 10g For Everyone  Eliminate need for 3 rd party components that add significantly to complexity and cost  Single system image management  Automation of workload management  Full integration with other key Oracle features  New and improved verification and diagnostic tools  Zero downtime patches  Performance improvements

RAC for Everyone – Integrated Clusterware  Complete Oracle cluster software solution  Single-vendor support  Low Cost – No need to purchase additional software – Easy to install, manage  High quality and functionality across all platforms  Large number of nodes  Common event and management api’s – Multi-tier HA & minimal MTTR  Support for third-party clusterware Applications RAC, Other Apps Services Framework Cluster Control/Recovery APIs Automatic Storage Management Messaging and Locking Membership Connectivity Event ServicesManagement APIs Hardware/OS Kernel

RAC Enterprise Manager Integration  Service Consumer Page  Shows alerts for SLA violations  Cluster Page  Cluster Database Page  Performance Page

RAC for Everyone – Server Provisioning – Provision software to many systems at once – Clone, store and distribute “known good” configurations – Automate patch and update management Software Inventory Enterprise Manager
