Cary Millsap is the founder and president of Method R Corporation. He is widely known in the Oracle community as a speaker, educator, consultant, and writer. He is the author (with Jeff Holt) of Optimizing Oracle Performance and a contributor to Oracle Insights: Tales of the Oak TableMethod R Corporation is a Cary Millsap company that is committed to genuinely satisfying software performance. The company creates software tools, education courses, and consulting services dedicated to helping software application systems run faster and more efficiently. Method R focuses predominantly on Oracle-based systems, but it has the worldwide network in place today to assist with Microsoft SQL Server performance issues as well. Career SummaryOracle CorporationCary worked at Oracle Corporation from 1989 through 1999. In the early 1990s, he created Oracle's OFA Standard, which became the default configuration standard for Oracle software installations worldwide. Many of the SQL scripts he distributed throughout his Oracle career (called "Oracle APS") are still in use today. At Oracle, he accumulated various honors including Oracle Consulting's "Consultant of the Year" award. He visited hundreds of clients on performance and architectural projects and spoke to thousands of architects, DBAs, and developers in courses, seminars, and user groups. He was a founding member of the Massive Open Systems Environment Standards group, where he worked directly with Oracle Development and Marketing to help shape features that Oracle would release in versions 7 through 11. When he departed Oracle in 1999, he was a Vice President in charge of 85 performance consultants and a 15-person service line group that constructed system architecture and system management services for Oracle Consulting practices worldwide.Hotsos Enterprises, Ltd.In 1999, he co-founded Hotsos Enterprises, a company dedicated to Oracle performance. At Hotsos, he pioneered the idea that a full and unambiguous account of an Oracle session's end-user response time (called a profile) could be obtained from Oracle extended SQL trace data. The motive and means for obtaining this information helped to revolutionize the way Oracle performance analysts work. To explain the process, he wrote Optimizing Oracle Performance with Jeff Holt, which earned Oracle Magazine's 2004 Author of the Year award. He led the design and development of the Hotsos Profiler software package, which automates the most difficult part of implementing Method R for Oracle applications. He created and taught courses and seminars to Oracle practitioners at events all over the world. He co-founded the Oak Table Network, a loose association of like-minded people who make their livings from their expertise with the Oracle database engine and their skill at handling performance issues. In 2007, Oracle Corporation granted him the status of Oracle ACE Director.During production of Optimizing Oracle Performance, Cary established and proved the theory that the location of the "knee" in an M/M/m queueing system's response time curve depends only upon the system's number of parallel service channels (m) and is in fact independent of the arrival rate (λ) and service rate (μ). This result makes it possible to plan computer capacity requirements with much simpler models than practitioners had tried to use in the past.
