Hotsos Symposium Speaker – Jarod Jenson
Mr. Jenson is a prior Hotsos Symposium presenter.
Biography
Jarod Jenson is Chief Technology Architect at Forsythe Solutions Group, Inc. (www.forsythe.com). Jarod has a background in designing and implementing business critical systems. His areas of expertise are in system performance, reliability, and security.
In assessing the performance of a customer's system, Jarod profiles each tier and layer involved in the application. This includes everything from the Oracle database, to custom or third party applications, and the operating system. Over the past five years, Jarod has looked at hundreds of unique solutions throughout dozens of industries.
Routinely, Jarod uses DTrace in the Solaris Operating system to assist in the remediation of performance problems of Oracle-based implementations. The observability of DTrace coupled with the extensive Oracle based profiling tools has yielded a 100% success rate to date.
Jarod has also presented at JavaOne, SunNetwork, and various other conferences and symposiums.
Presentation Title
Dealing with Software Agoraphobia: The World Outside Oracle's Walls
Abstract
For any business critical application, there is really only a single metric necessary to determine the overall performance of the system – the relative happiness of the end user. When the end user is not happy, the responsible technologists find themselves scrambling to determine the source of the underlying issue. Generally, this involves each person (or team) working in isolation and focusing only on the components of the application for which they are directly responsible.
The attendees of the Hotsos Symposium are either already quite well equipped to dive into the substantial diagnostic tools available with Oracle (extended trace data, AWR and ASH tables, statspack, etc.) or will soon be so equipped. However, Oracle is rarely the only moving part in today's complex applications. To truly understand the performance profile of an application, we must be prepared to move across the layers of abstraction in an effort to find the underlying source of a performance pathology. The ability to correlate observations at one layer with the behavior at another layer are essential.
This presentation is intended to augment and expand the metrics available from Oracle in an effort to understand the role of the operating system, network, disk IO, and dependent middleware applications in the role of overall systemic performance. Tools and methodologies available in today's operating systems have expanded, giving us new means to cut across the layers of abstraction and identify performance inhibitors that exist at these points of interaction.
In addition, advances in the underlying hardware (multi-core chips and chip multi-threading (CMT)) have altered time honored traditions in the world of capacity planning and performance analysis. Some of the subtle nuances of these platforms will be discussed as well to understand their proper role in the modern datacenter.
This presentation will be littered with copious demonstrations of these tools and techniques.
