At that point, the Florida announcers start talking about the 2 Georgia players who are now wheelchair bound, one in a motorcycle accident last year and one in an on-field collision with a teammate this year. I'd have to say that the announcers got a little carried away with the drama of the moment.
Anyway, I've seen guys get hit before, perhaps I've been hit, I can't remember, but I've never seen something like this.
The pitcher appears to be OK, he suffered a mild concussion...a scary moment but he seems to be OK. Had to be hard on the kid that hit him too, who was just announced as a finalist for the Golden Spikes Award as one of the premier college baseball players in the country.

I tend to write a lot during these events, but since I decided to rebuild my laptop the day before I went, I hadn't worked out all the kinks (specifically my wireless adapter), I hardly used the thing. I spent the majority of time on "my" table, the Motorola Xoom. Since getting this device, my son has owned it...which appears to be the norm in most households with young children.
Day 1, technically Day Zero
This was a Masterclass by Mark Rittman (@markrittman) and Tony Heljula (Hallelujah!) (@aheljula).
Mark was up first and spoke about OBIEE 11g Architecture and Internals (pdf). It was nice to get a big picture view from the architecture side from someone who has been working with the latest release for quite some time. From my understanding, this is the very first Fusion-like app released...but I could be wrong. Mark ran long, everyone had lots of questions which Mark graciously answered.
Big Side Note
Please bring an extra liver to these types of events, especially if you have a number of people from the UK in attendance. I have a beer or 3 regularly, but this is just nuts. I declined invitations to go out too (which got me quite a bit of ribbing). My roommate, Jason Baer (former colleague and now RM employee) was ruthless. He'd roll in around 3 AM, wake me up, give me a hard time and then get up before me, shower and dressed before I even woke up. I'm getting old.
Next up was Tony Heljula. I had never even heard of Tony before that day...either I'm losing my touch or he's hidden himself somehow on the European Internet.
BTW, you don't pronounce his name Hallelujah, but I do now. It is easier to remember.
Tony spoke after Mark on the Spatial and Mapping Integration in 11g. I've used neither of these components; the Map Viewer in OBIEE nor the spatial stuff built into the database. Very, very cool things you can do there.
Lunch. No beer. Thankfully.
Mark was up again on OBIEE 11g BI Server New Features and RPD Modeling. To summarize some of the new features:
- ID Columns for Descriptive Columns ("Double-columns")
- Lookup Tables (Yeah!)
- Support for Ragged, Skip-Level and Parent-Child Hierarchies
- Hierarchical Subject Area Columns
- LTS Priorirty Ordering
- Repository Passwords
- Deployment of Repository Files using FMW Control
I've followed the Rittman Mead blog closely since the release of 11g, so not much of this was new to me, but it was fun to see Mark speak for the first time.
To end the day, Tony spoke on SOA integration. You might wonder WTF that has to do with OBIEE...I did, at first. As he worked through his example though, it made perfect sense. The question I didn't get to ask was whether SOA was the way forward and the OBIEE write-back functionality would be deprecated eventually...I'll get an answer to that shortly I hope. Read Tony's presentation here.
For all the presentations, both in Brighton and Atlanta, check out Mark's post today.
Great first day...it had been some time since I could just relax and take-in the presentation without worry of blogging right after, which was nice.
Brighton is on year 3, this was the first event in Atlanta. Here's to making this an annual event.

My very first post from a mobile device, so forgive my spelling please.
I arrived on Tuesday evening driving from Tampa...a wonderful 8 hours away from the computer, something I haven't done in quite some time. Upon leaving, my wife said I had become like a piece of furniture...she's most likely right.
So far I've seen Mark Rittman speak twice on 11g architecture and internals, Tony Heljula (pronounced halalujah or something) on integrating SOA, Jeff McQuigg on intermediate to advanced metadata techniques (basically making the RPD your bitch :-) , Kevin McGinley on the mobile side of OBIEE and Suyog Rao on security...which was probably the most contentious of talks so far.
The nights have been fun too....you know how much I enjoy the social aspects of these events, this has been no different. There are 50+ passionate and smart people here, so the conversations are awesome. Add beer for even more awesomeness.
Overheard tonight about me, I am eccentric. Shocking. I thought I was normal. :-)
I will write more in the coming days, just a quick update.

After logging into the production server that contains the client tools, go to Start ==> All Programs ==> Oracle Business Intelligence and select the BI Administration tool
That will open up a shell window and eventuall the BI Administration tool will pop up.
Select File ==> Open ==> Online
A challenge screen will then be opened:
Enter the Repository Password, User and Password
You'll then be greeted with the metadata for the online repository.
There are 3 layers to an OBIEE metadata repository:
- Business Model and Mapping (BMM)
You only need to worry about the physical.
The arrows in the above picture point to the objects that you will need to modify, the Connection Pools.
Double click on the Connection Pool you need to update. You'll be asked if you would like to check it out.
Now the important part. The Connection Pool properties box will open up. Make sure you are on the General tab and then locate the Password text field.
Enter the password for the specific user into the Password text field.
When you hit OK, you'll be prompted for the password again.
Enter it and hit OK.
Repeat this step for each of the Connection Pools in the environment. Each physical database has one or more Connection Pools, so you must update them all.
Now you must Check in your changes and then Save them.
After hitting the Check in button and the changes have been, checked in, that button will become grayed out. When that happens, click on the Save button.
These changes will be immediately applied to the repository.

OBIEE performance – get your database sweating by Robin Moffatt (@rnm1978). Much of this is common sense, or so you'd think.
Mr. Moffatt, for the past year or so has been seen getting more into the performance side of things. On Twitter, I see him engaging Mr. Millsap, Ron Crisco, Alex Gorbachev and whoever will listen on the best ways to go about 1, monitoring 2, instrumenting 3, fixing, 4, everything else. This is good news for all of us.
Earlier in the week I received this email:
WTF? I've never left a comment on a youtube video. I click through to see this:
Ugh...My son. He's pretty much ruled the Xoom since we got it a couple of months ago and he watches all the Rome Total War videos (I did learn that the History channel used the creator's graphics engine for the re-enactment of ancient battles...good to know). Anyway, I let him use it and it uses my Google account.
He had asked about a week ago how to leave comments and I told him that he wasn't allowed to. Apparently he had done this before asking. I chastised him appropriately. We banned the Xoom for a week.
I can't help but laugh though. I sent it to Kris then ran downstairs to make her look too. LC wanted to know what we were looking at and I had to kick him out of the room because I saw Kris' face start to light up in laughter. It was funny, but we have to be parents.
That's all I got...the well is dry. I was hoping this would stir some thoughts, but apparently not.

When was the last time you were in "the zone"? I'm talking about that special moment when you are able to construct a mental representation of a complex task with none of its parts missing. You've managed to take a large problem and break it apart into smaller pieces that you fully understand thus giving you a clearer picture of the original bigger problem. At this stage you are completely focused, ideas are flowing, and you feel confident what seemed like a daunting task is now under your control. This mental state is typically associated with programming or software development but it applies to pretty much any task that requires deep focus and concentration. Programmers in the movie The Social Network were known to be "wired in" when they were in the zone
For me, this is usually achieved when I'm alone at work or at home. The seating arrangement at work is great for collaboration since I share cubicles with three colleagues but makes it almost impossible for me to get in the zone.
Recently I had to optimize a large query that feeds a Crystal Report. Notice I said query, not queries, so all the data was gathered with a single query. This query was actually a UNION of several queries each joining tables, views, inline views, and a few IN clauses. It wasn't until I was able to enter the zone that I managed to make significant progress troubleshooting the monster query and develop a solution that made a significant impact.
What are some of the hurdles that prevent us from entering the zone? Are they limited to the office? Perhaps it is better to work from home, but is that even a plausible option? Emails, phone calls, instant messaging, impromptu meetings, people asking for help and casual conversations make it very difficult for someone working on a complex task to enter the zone. Working from home could aggravate the issue since the only means of communication are limited to phone calls, emails or instant messages. Nobody knows how busy you may be so interruptions might occur more frequently than if you were in the office.
How do you find the zone? As with everything else this could be a matter of personal preference. Some people (like me) prefer silence and virtually no external stimuli while others are content and strive in the midst of chaos. Regardless of what your style may be one thing is certain: it is almost impossible to achieve deep concentration if one is frequently interrupted. Unless you possess special mental abilities that allow you to context switch as quickly as a modern CPU, most everyone requires a special setting and the right conditions in order to enter the zone.
The average IT professional would be more productive and enjoy greater job satisfaction if he/she is able to enter the zone more often. We would be able to develop better designs, troubleshoot more efficiently, and devise smarter solutions. Entering the zone is a rewarding experience not only because it helps us solve complex problems but because it shows us the level of mental prowess we are able to attain.

Off to my local instance.
SYS@TESTING>SELECT * FROM dual;How about (I swear, this was the first one I tried), SET TERMOUT OFF. That didn't work. (Now guessing) SET ECHO OFF? Nope.
1 row selected.
To recap, I want to mimic the behavior of SET AUTOTRACE TRACEONLY where there is no result provided AND I don't want all that other stuff.

@mgralike, @hillbillytoad, @nlitchfield, @boneist and @dhaimes all jumped in the fray. @hillbillytoad was definitely the most difficult (as usual).
I'll use Storify to tell this story again (so I don't have to screenshot each and every message, in order, and put them in this post).
So the end result?
Create a script, call it test.sql. Put your query in there. From SQL*Plus, issue SET TERMOUT OFF and then run your script. Magic!

I originally thought it would be something technology related, but I recently procured myself one of these:
See it in action here:
As a pitcher, I spent a lot of time doing nothing. Take a 3 hour practice. I throw for about 10 or 15 minutes, maybe a little bullpen work, I'm up to 25 minutes. Maybe some PFP (pitchers fielding practice), 40 minutes now. I might be asked to be a runner in situational practice, 1 hour. That leaves 2 hours. That time is spent shagging baseballs during batting practice (BP). While it can be fun, it can also be incredibly boring, especially if you're stuck on home run duty (all alone across the street).
I fought that boredom by becoming really good at hitting ground balls to infielders during BP. Freshman year, coach had wooden fungo bats. He wouldn't let anyone use them because we might break them. What did I do? I used them. I didn't break them either.
The pinnacle of being good with a fungo bat is probably the ability to hit pop-ups for the catcher, you know, the ones straight up that curve back towards the field. I can do that.
I've been hitting fungo to the 7-8 year olds where I'm the assistant coach. Sometimes I'll hit them hard, mostly soft, but I just remember how much fun it was.
Wait, one more thing to go along with that. BP pitcher. I throw great batting practice (I'm not sure if that's was a good or bad thing career wise, obviously doesn't matter now). It's fulfilling to be able to throw strikes and see how far people can hit them.
There it is, my dream job. Fungo hitter and BP pitcher.
I wonder if the Rays are hiring and if they'll pay me enough to support my family?

Well, someone had to back out. I won't mention names, but they didn't really verify the time and dates. Said person had the audacity to take a vacation!
I wasn't going to name names, but I will, it's Jeff Smith, aka @HillbillyToad.
I'm not really mad (just don't tell him, I like to keep him on his toes). I like Jeff's presentation style a lot, he came down and spoke to our user group about a year ago. He makes me almost want to use Toad. Almost.
Anyway, since he couldn't speak, I had to find another speaker.
Wait, I heard there was a big name attending last week didn't I?
That's right, none other than Mr. Thomas Kyte.
Maybe he would "fill in" for Jeff?
As is my mantra, the worst thing anyone can say is "No."
So I asked, and he accepted (and I must find a gift for his wife...).
So to recap:
Cary Millsap will be kind of a facilitator. Kris Rice will be speaking twice. Robyn Sands, Sten Vesterli, Sue Harper, Marc de Oliviera and finally the Dominic Delmolino. Wow. It's gonna be a great day!

Last week I started watching Glee on Netflix. I was bored and the selection on Netflix (streaming), well, sucks.
I have enjoyed the show, must to my surprise. It would fun to sing "responses" to stuff...mostly for the cheesy factor. I really hope that's the comedian in me.
Tired of the Fat Jokes
I wrote about this earlier in the week. I tend to write "on-the-fly" without editing or any such thing, so it was natural that I left out quite a bit.
What I did not mention is probably more important as that article focused mainly on how I felt.
As a dad of 2, one with special needs (and I'm not just saying that because she is a girl :) ), I have a lot of work to do outside of my professional responsibilities. Playing with them is #1 on that list. Mom deals with the day to day operations while I'm like the Cruise Director, maybe Captain of Fun. At least I should be. This weight thing affects how I interact...in that I get tired way too easily or I just simply don't want to (or can't) play. That blows.
We lived in Simi Valley, CA from 1979 to 1983. My dad worked in downtown L.A. off of Wilshire Boulevard. During the week, it was a 2 hour commute, each way. Despite this, he would still come home and play catch with me or take me to the local school for some batting practice. I want to be more like that.
And then there's the, "I'm gonna die" thoughts, if I let this continue. That might be overstating things just a tad, but to fall so far from grace, those thoughts are hard to shake. I don't know what "normal" people are like, i.e. ones who never exercised like I once did. Maybe I'm crazy for thinking like this, but that wouldn't be much of a surprise.
Finally, there's the thought (related to the previous) of what would happen if I fell over? Currently, I don't have life insurance (working on it though) and we have $0 in savings. Since I'm on a 2 month schedule consulting, that would be good, but doubtful that would cover the costs of my funeral (Roman Pyre, Irish Wake, perhaps a New Orleans Jazz Band in there somewhere...). I can't leave my family in a lurch like that (Yes, I would be missed, I understand that, by housing and food, the basics, are my primary concern).
Finally Part II, the fear of not seeing the little monsters grow up, or simply growing old with Kris. That more than anything, scares me. I remember a time where I never concerned myself with such things, then LC showed up and suddenly I had a sense of mortality.
So the little monster requires surgery next week. Ugh. Didn't go over well in this household, last time was teh suck.
We know her record with Death, and it's good. She's given him The Bird twice so far. That's why she's a Rockstar.
Besides, this one is not GA, it's just to remove some ear tubes that never fell out. Should be in and out in a short period of time.
Dang, initially, I had some funny ones in here. I started out funny, then devolved into the morbid.
I'll do better next time. :)

I'm hearby naming all my future DBAs that meet certain criteria, &DBA.
Over the years, at about a million different organizations, I have met many DBAs. Many, at first glance, fit the DBA stereotype; cranky, condescending, arrogant, etc. After further review, many of those traits still apply. Some however turn out to be the opposite; they just put on a game face for the new guy or gal because they've been through this before...probably to be disappointed again that the developer will 1, leave them out of design discussions 2, throw bad SQL over the wall, 3, not use bind variables, ever and 4, well, all the other bad things we developers do.
The type that I have least encountered are the DBAs who actively seek out and engage developers. Hey, can I help you with that? Hey, you aren't using bind variables, here are the reasons you should. They know that in the long run, the better the developer, the easier their job will be.
I love that aspect of my job. I like helping others learn to do something better or more efficiently. I like to encourage others to download and install the database. But that's not the point of this post...
I needed a name for those DBAs who are 1, less qualified than I am to be a DBA (short list, I am under no illusions), 2, are wholly incompetent and 3, are jerks.
After a recent incident, as relayed by others, the &DBA was born.
What does the & mean?
In SQL*Plus, the & is a special character. If you run scripts you can parameterize them with &COLUMN_VALUE or something, right?
That's great for scripts.
It can go horribly wrong with code. At least the first time you try to load code via SQL*Plus. Here's the original
CREATE OR REPLACEand here's what happens when I run it:
FUNCTION foo RETURN VARCHAR2
l_value VARCHAR2(30) := 'Barnes & Noble';
SELECT 'IT WORKS!'
WHERE 'Barnes & Noble' = l_value;
CJUSTICE@NO_CLUE>CREATE OR REPLACEThis is how it is stored in the database:
FUNCTION foo RETURN VARCHAR2
3 l_retval VARCHAR2(10);
4 l_value VARCHAR2(30) := 'Barnes & Noble';
6 SELECT 'IT WORKS!'
7 INTO l_retval
8 FROM dual
9 WHERE 'Barnes & Noble' = l_value;
11 RETURN l_retval;
13 END foo;
Enter value for noble: show errors
old 3: l_value VARCHAR2(30) := 'Barnes & Noble';
new 3: l_value VARCHAR2(30) := 'Barnes show errors';
Enter value for noble: testing
old 8: WHERE 'Barnes & Noble' = l_value;
new 8: WHERE 'Barnes testing' = l_value;
Warning: Function created with compilation errors.
FUNCTION foo RETURN VARCHAR2Yeah, that won't work.
l_value VARCHAR2(30) := 'Barnes show errors';
SELECT 'IT WORKS!'
WHERE 'Barnes testing' = l_value;
12 rows selected.
To fix this, you simply set an attribute/directive? in your SQL*Plus session, SET DEFINE OFF (I believe there is another, but this is the one I use). Like this:
CJUSTICE@NO_CLUE>SET DEFINE OFFAll is now well in the world.
CJUSTICE@NO_CLUE>CREATE OR REPLACE
2 FUNCTION foo RETURN VARCHAR2
4 l_retval VARCHAR2(10);
5 l_value VARCHAR2(30) := 'Barnes & Noble';
7 SELECT 'IT WORKS!'
8 INTO l_retval
9 FROM dual
10 WHERE 'Barnes & Noble' = l_value;
12 RETURN l_retval;
14 END foo;
CJUSTICE@NO_CLUE>SET DEFINE ON
Now this might be vexing on your first couple of weeks on the job, but you quickly pick it up.
This is where the name comes from...
SET DEFINE OFF
SET DEFINE ON
said that this was a known Oracle bug.
In January, we talked Tanel Põder into taking a vacation from his vacation. Now, we get Cary Millsap of...well, fame.
If you don't know who Cary (@carymillsap) is, you should. From his blog:
Hmm...I thought he had Teacher in there. Here it is from his Google Profile:
I really like that, Teacher. Teaching.
Like Tanel, I don't understand many of the finer details, I do not have that kind of experience. What makes Tanel, and Cary, stand out, is that they can make these complex topics easily consumable by mortals.
Sign up details are here.

What's sad, to me, is I used to have a resting heart rate in the low 30's. Now, and for a number of years, I walk up a flight of stairs and I'm winded. FFS.
My last triathlon was an ironman distance race, you know, 2.4 mile swim, 112 mile bike and a marathon just for fun. I didn't finish that race, I didn't really train for it either. I quit at the beginning of the last lap around the lake...I had already passed the Finish Line twice, to cheers, which wasn't very nice.
The 2 years prior I had trained, but I got hurt right before the race both times. It also happened to coincide with 1, getting married (2 months later), 2, turning 30 (1 month after), c, changing careers (4 months later) and IV, buying my first house (4 months later). I like to go Big it seems. 30 was a banner year. Oh wait, how could I forget, one week prior to the wedding (and a couple of weeks after the race), Kris and I found out LC was on his way. Big.
I don't expect to get back to former glory:
If you've met me in person, I've probably shown you this picture within about 12 minutes of meeting you. I'm proud of that picture and I probably show it to everyone because...I'm embarrassed of how far I've let myself go.
Last doctor's visit, 257. I weighed about 170 there.
I used to joke and say I retired during my 30's, that's when competition is brutal in triathlons. Seems to be the sweet spot for getting good. I went the other way, I'll skip all the craziness and come back in my 40's.
I'm 39. 40 in November. I'd like to race again.
That said, I'm the proud owner of this little baby:
I had one...10 years ago too, but sold it to start my own business in 2004. Actually, here's the eBay pic of it:
I've also purchased an HR monitor, that will give me some feedback (about how out-of-shape I really am). In true nerdly fashion, I'm tracking it here. My desire to keep that up to date...and just get data in there, will help motivate me. Gamification?
So there it is. Hopefully it will be "Fat Guy Loses 60 lbs" come my 40th birthday.
