Missing UKOUG Tech13 — But Still in Manchester at OakTable World UK 2013

This is the first year since 2006 that I don’t present or attend the UKOUG Technology annual conference. Sad, but I had to withdraw because I didn’t believe UKOUG had been making the right choices in the past little while. The trigger was the introduction of the limit of six presentations per company to present at the conference. I believe this doesn’t really serve the conference, attendees or my company well (which I’m so passionate about,) nor my colleagues that I’m so proud to work with.

IOUG Collaborate Deep Dive slides — Deploying Oracle Database 11gR2 for High Availability by Alex Gorbachev

Quick blog post from Collaborate 2012 in Vegas. I’m only doing one session this year but it’s a very long session — I’ve just done a deel dive on deploying Oracle Database 11gR2 for High Availability. It’s a broad topic and my plan was to focus a lot on basic concepts and how they are [...]

Alex Gorbachev Presenting at TOUG’s DD Day on 28-Oct-2011 in Toronto

While Oracle OpenWorld is still hot in our memories, I’m going to be presenting two of my OOW11 sessions at the Toronto Oracle User Group’s DD Day 2011 on 28-Oct-2011 — in just a bit over 2 weeks. Last time I presented for TOUG at their summer meeting in 2008 which makes it a tad [...]

Presenting at TCOUG 2011 Winter Meeting

I just arrived to Minneapolis, MN and will be speaking tomorrow at the Twin Cities Oracle Users Group 2011 Winter Meeting. It’s the first time I’m speaking for this user group so I’m excited to meet the new audience. I will present one hour version of my Grid Infrastructure Internals session. Of course, no demos during presentation as it’s just enough to cover the theory slides but I’ll leave the demo as a homework as usual. :)

Big thanks to Klara Hribkova, Vice President of TCOUG, for picking me up at the airport and organizing a dinner. I’ve had a lovely meal — Bison Pot Roast — melting in my mouth.

I’m staying at Doubletree Hotel Minneapolis-Park Place. Nice and clean and very friendly staff but what’s interesting about this hotel is that they have DSL modems in the rooms so each connection is going via its own DSL line. Isn’t that cool? As I logged in, I realized that complimentary internet is shaped to 512Kbit only and faster connections are charged extra. Oh well, I can’t complain about free. Still, having DSL modem in the hotel room is kind of unusual! :)

I should also mention that it’s really cold here with temperature just like in Ottawa — about -20 °C or below zero in Fahrenheit. At least, no wind chill like in Ottawa.

I want to mention that my experiment on collecting database consolidation stories was a *relative* success — we’ve got slump of participants and I can announce the book winner — Noons, it’s yours! :)

If you are at the TCOUG meeting tomorrow by any chance (well, today already), please catch me to say hello!

News from UKOUG 2010 Conference

Right now I’m sitting in the speaker lounge with Jeremy Schneider after hacking some RAC ASM stuff as a follow up to my last presentation. We were testing some failure scenarios but that’s a topic for another blog post.

Dan Fink cheated with his tiny blog post which was more like a twitt-long (and so did Christo.) so I thought to write something properly.

Monday started early for me — 6am. Quick run through my demos again and early breakfast. Registered before 8am while it was still empty and then joined Tom Kyte in the speaker lounge. We both had our sessions starting at 9am but Tom is a Pro when it comes to presenting — while I was taking the last minutes to go through my slides and do minor adjustments, Tom was calmly replying AskTom questions. Oh well, such is life.

My 2 hours presentation was a little slow and I wish the audience was a little more engaging but maybe it was just because all the locals hit the hibernate mode following “extreme” cold weather and didn’t quite wake up after the weekend (of course, there is not chance that it was bad presentation material or speaker…. no, no!). This was the same presentation as I’ve done at the OpenWorld but I included demonstrations of 11gR2 Grid Infrastructure and that was the tricky bit. In the end, everything pretty much worked with one small surprise. My last demo was troubleshooting of startup and I decided that I will screw up 3 things and troubleshoot online *first* time. I.e. I decided deliberately not to practice it. The latter wasn’t very smart as I had less then 10 minutes left. After few minutes of shame I had to move this demo in the list of homework. :) The good news, that I did go through my last slides briefly and I wanted to be brief there as Frits Hoogland was covering this area in more details later that day in his own session.

Exhausted after my session (and slightly disappointed by inactivity of the audience), I was very hungry but decided to wait until the official lunch time so ended up in Graham Wood’s session on some hidden free gems along with Christo and Jeremy. We did have a plan to switch to the Exadata round table and did just that. I’ve got a little disappointed with the round-table format (as I’m writing this — discussed it with round-table moderator, Joel Goodman, here in the speaker lounge and we agreed on this) – it was more like a presentation without slides with introduction to Exadata for folks who don’t have any background knowledge. It should have been a presentation while the round-table should have been left for the folks with experience or knowledge of Exadata technology.

Having been late from Exadata round-table I was late to lunch. This means I was late to the next session and managed to sneak in the last 10 minutes for Frits Hoogland‘s Oracle Clusterware 11gR2 In-depth. It looked like the audience wasn’t very active during his session either. When I spoke to Cary Millsap later, he also mentioned that it was somewhat a struggle to get the audience to laugh so he had to leverage his special jokes from the reserve list. I might borrow some of them in the future. :)

Next I went to the Tanel Poder‘s presentation on Exadata migrations and related performance tuning. Very insightful as you can expect from Tanel. He also confirms that Exadata performance rocks but it can be tricky to run stable. I think our experience was somewhat better with stability except early months when lots of issues were not fixed.

Afterward, I went to Cary Millsap‘s presentation on reading 10046 trace files. My intention was not to learn the subject that I was already familiar with but to learn how Cary can present this topic in his new style (with very few words on the slides). Turned out that he did put trace content on the slide but it was interesting to see how he emphasizes what he really wants to talk about in the 20 lines of code on the page. I will borrow this for my future presentations.

The final session of the day was Julian Dyke’s replication internals. It’s been a while I wanted to dig into replication deeper so it was a good move to go there. However, after such an active day (and night), I was struggling to stay awake even though my brain was desperately trying to keep up. The good news is that Julian have very well illustrated slides so I can always get back to it.

That evening, we had OakTable dinner. It was, of course, at the Indian restaurant. I admit I abused that place and barely was able to walk after dinner and struggled to consume anything more that evening. Still, nothing stopped us from hanging in Tap & Spile until almost 2am and even catch the last order of scotch at Jury’s. That was another abuse of the night especially that I had a presentation to deliver next day. Fortunately, the next day consequences were very mild but that evening brought me the idea of a demo for my presentation (thanks Christo) and most of Tuesday I spent getting this demo ready. It worked very well but I will need to improve few items to run it faster.

It’s already Wednesday as I’m finishing this post now. The night was lots of fun and it was long and… very late. I recall that the most bizarre idea of that evening was robbing a bank (don’t ask how we got there… it was not my fault). I didn’t really pay attention when I was back in my room and crashed but I see my last email from the phone was sent at 4:25am (Hi Doug!).

I missed the presentation on marrying Grid Control and Nagios — very interesting topic for me as some of our customers happen to use both. I struggle to understand why one would want to integrate these tools but that’s why I really wanted to see it. Oh well, I have to review the slides offline and I’ve met the author the evening before so I could always contact directly (thanks Eter!).

Half more day to go. Still struggling to decide whether I should go to Julian Dyke‘s presentation on memory (I know Christo did his this morning but it was way too early for me) or to the session on RAC Server Pools by Bob Mycroft (somehow, his name is associated with Windows – is it just me?).

Oh… I completely forgot to mention that the highlight of Monday night was Doug Burns shaving ceremony and finalizing it at Tap & Spile. I have captured some videos but they need some post-processing before I can publish them. Another highlight was watching photos of previous UKOUG conferences I attended and I specifically liked one photo that was not supposed to be there! It won’t make sense to you my dear reader but please forgive me and ignore it — it’s meant only for one of you. ;-)

Pythian at UKOUG Technology and E-Business Suite Conference 2010

Hello Birmingham!

It’s past Sunday midnight and I’m stuck in my room in the last couple hours finishing my slides for my masterclass tomorrow. Turns out that I’m presenting the very first session of the conference at 9am. I wish there is a keynote instead so that I could grab one more hour of sleep (it’s going to be deep into the night back home in Canada). Strange that the keynote was moved to Wednesday — I hope UKOUG has really good reason for that!

My two hours masterclass will start at the same time as Tom Kyte’s a-la keynote session — what a competition. On the other hand, there is no other sessions in server technology so I expect that folks without interest of database development will automatically end up in my session. I’m in Hall 5 – quite large room. Is it the second biggest room after the Hall 1?

I will need to work hard to keep the audience… maybe I shouldn’t plan for any breaks to make sure I don’t let folks slip out to the next sessions like James Morles’ Sane SAN 2010 or Jeremy Schneider’s Large Scale ASM.

My masterclass is based on the slides that I presented at the Oracle OpenWorld few months ago which, in turn is reworked session on Oracle Clusterware internals that I’ve done number of times as long session with demos. I thought updating this material to 11gR2 would be easy… Boy was I wrong!

11gR2 Grid Infrastructure has changes so much that it took me much much longer to get something sensible ready. I also had to limit the scope a bit as Grid Infrastructure has become so much more complex than older pre-11gR2 Clusterware. (stop complaining Alex!)

Anyway, everything is ready now and demos look reasonable. It will be a bit rough doing it first time – I’m sure I’ll stumble few times but fingers crossed we get to the end timely. I actually hope to finish early and allocate a bit more time for Q&A and potential ad-hoc demos at the end. But enough about me…

Who from Pythian are at the UKOUG conference this year? In additional to myself, it’s Christo Kutrovsky, Daniel Fink, Paul Vallee and Andrew Poodle. Christo, Dan and myself are presenting, Andrew is helping organization of MySQL track as a MySQL SIG Chair and Paul… well, I’d say Paul is a slacker so he is covering the beer tap to pay up! :)

It’s close to 2am – gotta get some sleep before tomorrow. Few words against Jurys Inn Hotel this year. It’s the first year I’m having so much troubles here including no early check-ins, not working phones, no internet in two rooms (I had to switch twice!), and somewhat unfriendly stuff this year. Has hotel management change since last year or what? Will consider another hotel next time I think.

Oh… and it’s indeed bloody cold here! So cold that it seems to impact the amount of girls-who-forgot-their-skirts-at home at the Broad Street. This unusually cold weather does impact travel plans of other conference speakers and attendees. Doug Burn seems to have been delayed for like a day and barely made it to have a pint at Tap&Spile – I wish I could accompany the crowd there until late but thanks to the awesome schedule (and unfinished state of my presentation, to be fair) I had to miss some of the fun.

PS: I have another session on Tuesday — Analysis of Oracle ASM Failability (should be Fallibility I guess but I’ll keep it misspelled simply because I can!). If anybody wants to catch up for any reason (like buying me a beer) — text me at +1 613 219 7031. iPhone doesn’t work with data-plans here for unknown reason so no twitter/email on the go.

OOW10 Bloggers Meetup Agenda — T-shirts are Back and More…

Almost time for the Annual Bloggers Meetup @ OOWCounting down. The details are finally organized — this year, we have not one, but TWO great prizes at the Oracle OpenWorld Bloggers Meetup.

1) T-shirt art contest on stylish Pythian designer t-shirts — one lucky blogger will receive an HP X310 Data Vault, generously sponsored again this year by HP.

2) For the best, most creative blog post about the meetup itself, Pythian is giving away an Apple TV. But, there are a few small rules:

  1. the blog post must use as many names of people in attendance as possible.
  2. the blog post must be readable. It needs to make sense to someone who wasn’t there. It must be a story and not a list.
  3. the blog post must contain one other small tidbit of information about each individual that you’ll uncover during your “networking” as you weave your fascinating stories of the evening (like their blog name, a contact detail, favorite color, title, hobby, cat’s name, certification, what they were drinking, how much they had to drink…).
  4. the entry must be posted by midnight on Sunday the 26th of September. Please reference this post in your blog and it should be automatically picked up by the blog engine and posted in the comment as a track-back (if it doesn’t appear in the comments for some reason — please do post the link in your comment!

Can you tell we’re trying to encourage a little more mingling? :)

And last but not least — all this couldn’t be happening without Vanessa Simmons who’s been orchestrating all of the fun this year. Thanks Vanessa!
