Where in the World Has Goth Geek Girl Been

I’m on track to fly home tomorrow, March 11th after nine days and three events.  I’m pretty exhausted and just ready to go home and catch up on some sleep…:)

I started out last weekend in Victoria BC and was thrilled to be on this emerald island of the Pacific Northwest.  British Columbia is gorgeous as it is, but Victoria is a special place that quickly became one of my favorite places in the world.

Hotsos 2016 Recap

I wanted to go to Hotsos Symposium for quite some time, having heard so many great topics from there for years. And every time I was a bit lazy to think about what I can talk about. Apparently I thought that everything I know is well covered elsewhere, so why would I be accepted. Plus all these complexities of budget, getting a visa, travel arrangements, jet lag, and personal matters in between. Last year, when call for papers was still open, I realized that there’s a good chance I can make it to Hotsos in 2016: I had a budget, visa is a doable thing, and most importantly I knew I had a topic to talk about which most likely will not be in competition with other speakers.

Presentation “Real-Time SQL Tuning” at Hotsos Sym2014 and UTOUG TD2014

This presentation was delivered at the Hotsos Symposium 2014 and at the Utah Oracle Users Group (UTOUG) Training Days 2014.

It describes a PL/SQL package that I put together called “ash_xplan.sql” which can be used to display real-time information about a SQL statement currently executing.  This package combines information from the Active Session History (V$ACTIVE_SESSION_HISTORY) or “ASH” view with information from the DBMS_XPLAN package.

As of Oracle12c v12.1, nothing in Oracle displays elapsed time while the SQL statement is still executing, not even SQL Monitor.

The source code for the “ash_xplan.sql” script is on the Scripts page of this website, along with sample spooled output.

HotSos Symposium and IOUG Collaborate 2016

I fly out on Sunday for HotSos and am looking forward to giving a joint keynote with Jeff Smith, as well as giving two brand new sessions on

Hotsos 2016

I’m going to Hotsos 2016 soon for the first time. I’ll speak about Middleware and the issues I see commonly everywhere. It took me quite some time to prepare for this trip: budget, visa, and, most importantly, presentation – required at least 120 hours of my time (which is a lot). In fact presentation is still work in progress and I hope to finish it just before March 8 when I’m presenting. I feel a bit nervous about my topic since the conference is all about Database Performance, the quality of presentations is always high and they are super technical, while I’m planning to have a light talk focused not on the Database mainly – just my rants on the things done wrong I usually see in the wild everywhere. It’s not something on the cutting edge, and some of my notes are so bloody old.

Hotsos 2013 – From Unstructured to Structured…

It has been a while that I have been attending Hotsos, although that is how it feels. In 2011 I flew to Hotsos to see, among others presentations from Maria Colgan, but I ended up being sick the whole week while learning on my hotel room to enjoy American TV. In 2012 I skipped Hotsos …

I’ll be speaking at HOTSOS 2011!

Hotsos is an annual conference that is devoted on Oracle system performance and the people presenting there are really passionate about their research and highly specialized about their subject area. Kinda geeky, but hey, performance is never boring.. and for me there’s still a lot of things to learn on each of the areas of performance and these are as follows:
