RAC IS PROVEN

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 3rd 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

RAC for Everyone – Server Provisioning

– Provision software to many systems at once– Clone, store and distribute “known good” configurations – Automate patch and update management

SoftwareInventory

EnterpriseManager

Enterprise Grid – Workload Management

Hands-free allocation and re-allocation of servers to services based on rules

– Automated routing of service requests to appropriate server with lowest load

– On server failure, automated re-allocation of surviving servers to services
