Linux Developer Survey Vol. 1, 2002, Evans Data Corp. 25 20 Percent of 15 Programmers 10 5 0 IBM BEA Oracle ColdFusion Jrun iPlanet Borland Other Oracle – Dell – Red Hat “Dell has worked extensively with Oracle to deliver the first Oracle9i Database Certified Configuration running Red Hat Linux and the first Oracle clustering certification on Dell / EMC storage” – Dell press release, 4/29/2002 Oracle Direct Support June 5, 2002 Oracle provides direct support for Red Hat Linux Advanced Server – First and only operating system that Oracle supports directly Typical Customer Quotes in the Press “(In the past,) no one could point to a version of Linux with Enterprise support…. With Oracle supporting it, that is a huge advantage.” – David Brown, Sr. Emerging Technologies Architect, Vector SCM, eWeek 6/10/2002 The Linux-on-Intel combination should give businesses a lower-cost alternative to running Oracle on Unix systems – Bernard Havlik, IT director of Menasha Corp., (InformationWeek, 6/10/2002). Typical Reactions by Analysts Gartner Group – "None of the other databases Linux supports have the shared, concurrent scaling potential of Oracle9i RAC." Meta Group – Senior Analyst Mark Shinman said: “…customers running Oracle9i Database on Red Hat Linux only have to work with one vendor to receive support, such as bug fixes and patches. This is actually giving some validity for Linux in the enterprise." Giga Information Group – Analyst Stacey Quant said: "The potential price-performance with Oracle on Red Hat will be much more preferable over (Microsoft)."

The environment allows us a lot more flexibility in hardware and increased cost savings.” John Kelly, Project Manager, KENROB & Associates Total Cost of Ownership (TCO) TCO study comparing databases on a single RISC server vs. an Intel-based Linux cluster – – Includes hardware and software license prices (including typical discounts) Includes maintenance fees, support staff costs, cost of money Hardware Pricing RISC based single server • 16-way Sun E6500 • 8 Sun Sbus Fibre Channel Network HBAs • 2 EMC Clarrion FC4500 disk arrays (576 GB disk) Intel based with RAC • 8 Dell PowerEdge 1550 2-way Pentium III 1.13 GHz rack servers, 2 GB RAM each • 8 Qlogic Fibre Channel QLA2200f • 2 EMC Clarrion FC4500 disk arrays (576 GB disk) Software Pricing For single Sun server, Oracle9i Enterprise Edition & Veritas For Dell - Linux cluster, Oracle9i Enterprise Edition with Real Application Clusters option, PolyServe Matrix Server – See http://www.polyserve.com for more information on PolyServe cluster file system for SANs Time of Purchase Costs With RAC, purchase servers as needed, reducing cost of capital – – – Quantifiable cost-of capital benefit Unquantifiable benefit from increased capital and infrastructure flexibility Later purchase may benefit from Moore’s Law Human Support Costs Support costs grow as size of cluster grows Slightly higher rate for RISC system administrators and DBAs Total Cost of Ownership $8.0 $7.0 Millions $6.0 $5.0 $4.0 $3.0 $2.0 $1.0 $Intel/Linux Matrix RISC Linux solution is 22.8% less expensive than RISC solution. High Availability Benefits? Real Application Clusters provide a higher level of availability than a single machine – – Hot standby Rapid failover Cost of Downtime Gartner Group estimates downtime costs $89,000/hour Standby configuration delivers 99.9% uptime Cluster delivers 99.999% uptime 8.5 hours more downtime with single machine Cost of Preventing Downtime To match availability characteristics, add a standby database server for the RISC solution Total Cost of Ownership $14.0 $12.0 Millions $10.0 $8.0 $6.0 $4.0 $2.0 $Intel/Linux Matrix RISC Linux solution is 53.1% less expensive than RISC solution.
