OMotion

OMotion moves a RAC-One instance from one serverto anotherwithout any downtime

Use Cases Load balancing

Server/OS patching and maintenance

Oracle supplied scripts control migration Services are not accepting connections on both nodes at thesame time

Migrated instance shutdown transactional once servicesmoved

A maximum of 30 minutes allowed for connections to migrate(then shutdown abort)


21/49

Rolling Online Patching

If the patch can be rolling upgraded with RAC then wecan do the same with RAC-One

Omotion migration followed by patching

When patching complete, the primary instance isbrought back online and the secondary instance is

shutdown (reverse Omotion)

Automatic Storage Management (ASM)

The foundation for Grid Storage

Easier to manage than file systems

Reduces storage costs

Provides best performance

Stores all data

ASM Disk

ASMDisk Group

Newin11.2


29/49

Easier to manage than file systems

Eliminates need for a cluster volume manager and filesystem Fewer components to purchase, install, manage, patch,

upgrade

Automatically creates and manages Oracle files

Just identify the disks for storage and leave rest to ASM Eliminates need to tune storage

All files distributed across all disks eliminates hot spots

Data redistributed online when storage added or removed


30/49

Reduces Storage Costs

Eliminate the need to purchase a 3rd-party volume manager orfile system

Eliminate the need to overprovision storage Can add storage just-in-time (online)

Reduce number of disks required to meet performanceobjectives

Automatically optimizes storage tuning

Increase overall utilization of storage via storage pooling

Eliminate downtime with hot pluggable (rebalanced) storage

Utilize less expensive storage

Tiered Storage

Advanced features eliminate need for high-cost storage cache


31/49

Intelligent Data Placement

Policy-based file placement forhot files on high performanceregions of disk

Classify files as hot or cold forplacement

Supports Oracle ExadataStorage Server

Save up to 35% on storage Increase storage throughput

performance up to 60%

Use Case: Place file system
