Pythian at HOTSOS Symposium 2012
Pythian continues its streak of events and speaking engagements in 2012 with HOTSOS 2012 on March 4-8, 2012, at the Omni Mandalay Hotel in Irving, TX. HOTSOS is the most important conference dedicated to Oracle system performance and we are honoured to have two great speakers representing us there. Alex Gorbachev and Gwen Shapira‘s abstracts are listed below and a full list of conference abstracts is available on the HOTSOS site here.

| Benchmarking Oracle Performance with ORION | Alex Gorbachev | Every time Alex demonstrates charts he produces during IO benchmarks with ORION tool (Oracle I/O Numbers), he hears “Wow! How do you create these?” In this presentation, Alex will provide practical tips and tricks on how to benchmark your storage subsystem and capacity, how to stress test it, and determine the limits. You will learn how easy it is to setup ORION benchmark and collect I/O performance characteristics of your platform and assess scalability of small random IOs, impact of writes on I/Operformance, impact of different RAID levels, how backups can affect your OTLP traffic, performance of outer areas of disks vs inner areas, compare SSD with HDD performance, and etc. Because ORION test scenarios are very repeatable, it’s a great measuring tool in your Measure, Analyze, Change, Measure cycle. |
| Queues, Pools, and Caches: The Right Way to Scale OLTP | Gwen Shapira | Transaction processing systems are generally considered easier to scale than data warehouses. Relational databases were designed for this type of workload, and there are no esoteric hardware requirements. Mostly, it is just matter of normalizing to the right degree and getting the indexes right. The major challenge in these systems is their extreme concurrency, which means that small temporary slowdowns can escalate to major issues very quickly. In this presentation, Gwen Shapira will explain how application developers and DBAs can work together to built a scalable and stable OLTP system – using application queues, connection pools and strategic use of caches in different layers of the system. |
