1 Oracle 10G Lindsey M. Pickle, Jr. Senior Solution Specialist Technologies Oracle Corporation Oracle 10g Goals Highest Availability, Reliability, Security Highest Performance, Scalability Problem: Islands of Computation Limited scalability, no resource sharing Must be configured for peak loads Single point of failure Slow to adjust to business needs Sales HR Files Procurement Supply Chain Financials Service Computing Eliminates Islands of Computation Introducing Oracle 10g Coordinated use of many small servers acting as one large computer. IT Problem High h/w & s/w costs Separate servers Configured for peak Single point of failure Hard to change Difficult to manage Solution Low cost components Shared servers Capacity on demand Fault tolerant Flexible Unified management Complete, integrated grid infrastructure Page 1 1

2 Automatic Automatic Eliminates need for conventional file system and volume manager Capacity on demand Add/drop disks online Automatic I/O load balancing Stripes data across disks to balance load Best I/O throughput Automatic mirroring Easy ASM How it Works Automatic No volumes: just a pool of storage Partitions total disk space into uniform sized megabyte units ASM How it Works No volumes: just a pool of storage Partitions total disk space into uniform sized megabyte units Efficient, online add/remove of disk with automatic rebalancing ASM How it Works No volumes: just a pool of storage Partitions total disk space into uniform sized megabyte units Efficient, online add/remove of disk with automatic rebalancing Automatic Automatic Page 2 2

3 Automatic Summary - Highest Data at Lowest Cost Low Cost Eliminates need for volume manager and file systems Works well with inexpensive, modular storage Gives better storage utilization Easy up to 50% less DBA/Sys Admin work Fault tolerant Raw disk performance Capacity on demand Automatic I/O load balancing ASM Mirroring Failure Flash Recovery Area Corruption Flashback Human Error Data Guard Site Failure Server Real Clusters Runs Real s Proven Over 500 production sites Certified with leading s Runs on standard, low cost servers Fault tolerant Server - Integrated Clusterware Portable to all platforms Low Cost No need to purchase additional software Easy to install, manage Easy Deploys in hours not days Improved single system image Single-vendor support Remains open to third-party clusterware Server Automatic Workload Push-button, online add/drop server to cluster via Automatic Workload Based on service concept Automatic routing of service connection requests to appropriate server with lowest load On server failure, automatic re-allocation of surviving servers to services Page 3 3
