Thanks for the warm welcome from all of you.
Like Cary, I have been trapped in the exciting weather event that has been
ongoing here in Texas. At times no water, no power, and no fun. It’s all coming
to an end now.
I have been working with Oracle in some shape or form for over 25 years. I have
never been a formal DBA, but I started off supporting the systems that ran
Oracle instances. First at Baylor College of Medicine with about 250 DB’s with
the largest - a whopping couple of TB - to support the Human Genome Sequencing
project in the 1996-1997 timeframe. From there I went on to (no booing) Enron
and was the Director in charge of over 3000 systems globally that supported
Oracle (over 6000 total systems). My familiarity with Oracle at this point was
predominantly how to build high performance infrastructure for deployment. For
some odd reason I left Enron and started my own consulting company - Aeysis. We
focused on performance of any application environment which clearly included
Oracle the majority of the time. As Cary mentioned I have been an avid DTrace
user since its inception. In fact, I was the first person to use it outside of
the 3 person development team (please port to Linux). When I met Cary at the
Hotsos Symposium, I was actually presenting on using DTrace along side Method R
tools to account for unaccounted for time. Essentially I began working my way
up from the OS (which I am quite familiar with) more and more into the database.
Something happened to Sun and a shift from Solaris/SPARC started in earnest
(the desire for cost reduction by companies had always been there). Also, I was
traveling about 48 weeks a year. With a wife and 2 young girls that was not
ideal. I decided to join Delphix as I found the product quite useful, and I
knew a large number of people already there for which I had a great respect. At
Delphix I started out as a Solutions Architect and then moved over to the
performance engineering team. I extended Kyle Hailey and Tim Gorman’s work
(shoutout) to perform sizing for Oracle databases. It was this work that really
got me into understanding the intricacies of how Oracle works. Given that I
still focus quite a bit on infrastructure and OS, I put the new knowledge to
work and built a single Oracle instance and Delphix engine that could sustain
over 12GB/s (big B) of disk IO over the network - neither system had more than
6 CPUs.
I still will never say I come close to being a DBA, but I do have a very strong
drive to make Oracle perform at its peak now that I am back consulting at
Aeysis again. I look forward to learning as much as I can here that I can apply
to my daily work as well as providing input when I can.
Thanks,
Jarod

I'm pleased to introduce you to the newest OakTable member, Jarod Jenson. I
met Jarod back in my Hotsos days at one of our Symposium events in Dallas,
and he's been a friend since. He was at the time (and still is) renowned for
his diagnostic skills using DTrace. Funny thing: Jarod's house is about three
miles from my house. ...No small feat in a country whose perimeter exceeds 19
miles. ;-)
Welcome to the OakTable, Jarod. Please introduce yourself to the group with a
reply-all. A paragraph or two is customary. Tell us a little bit about
yourself.
