me at Oracle Open World 2014

This day 3 weeks time (on the 24th Sept) I will be heading out to San Francisco for Oracle Open World. Over the course on 9 days I will be taking part in the Oracle ACE Director briefing and in Oracle Open World. The following outlines my main activities, sessions that I'm presenting at and sessions that I have been asked to attend.

25th-26th Sept. I will be at the Oracle ACE Director briefing. This will be my second briefing as it is a fantastic event where most of the SVPs and various VPs come in to tell us what plans Oracle has for the next few months and what announcements will be made at OOW. We even get Thomas Kurian in to talk to us for about 90 minutes.

Sunday 28th Sept. 9:00-9:45. I will be presenting with Roel Hartman on how to integrate Oracle Data Mining into APEX. The demonstration will involve how you can built BI dashboards in APEX and how by using Oracle Data Mining you can monitor customer sentiment over time. If we get time we home to show you how you can also use this customer sentiment (using Oracle Data Mining) to build some workflows in APEX. The presentation is part of the User Group Sunday Forum and will be in room 304 in the Moscone West building.

Monday 29 Sept. 18:30-20:00. Steven Feuerstein and Tom Kyte are hosting a special event that is a Celebration of SQL and Pl/SQL. Oracle Press has asked me and a few other authors to be at this event and this might have some copies of out books available. I was going to this event anyway as it is a great way to celebrate something that we us on a daily basis and for me for the past 21+ years.

Tuesday 30th Sept. 8:30-12:00. I will be at a Oracle Publishers Seminar. This is a special event arranged for people who have published books on Oracle with the main book publishers. I've been invited to this by Oracle Press.

Wednesday 1st Oct. is going to be a busy day between sessions, the Oracle Press book signing and the bloggers meet up.

10:15-11:00 (Moscone South 301) Fiserv will be presenting their case study on how they used Oracle Data Mining to combat fraud in online payments. Charlie Berger, the product manager for ODM, will be co-presenting. He has said he will be giving my book a plug and will point to me in the audience if anyone would like to talk to me about it.

13:00-13:00 Oracle Press has arranged a meet the authors / Book signing session. So during this time you will find me at the Oracle Press store at OOW. If you buy my book I will be on hand to sign it for you or if you have already bought the book then bring it along and I can sign it for you.

18:00-20:00 Every year at OOW this is a bloggers meet-up sponsored by OTN and Phytian. This is where us independent bloggers from around the world get to meet each other face-to-face and get to bond over a drink. As must of us blogger communicate in the virtual world this is a great event for us to put faces to names and to talk about our blogs. This will be in Jullian's beside the Moscone centre.

There are lots of other sessions and events on during OOW. I hope to get to as many as possible during the week. But the sessions above are the ones (at the time of writing this) that you will definitely find me at.

A big thank you has to go out to Oracle and OTN who are sponsoring my flights and hotel during this trip. This is part of the Oracle ACE Director programme. Also for many of the other events that go on during the week (and a bit) of OOW. Also a thank you to DIT for giving me the time to go to OOW.

OUG Mexico

We (Gorcan, Glen, Debra and I) arrived into Mexico around 10pm and had a few minutes wait for our local user group contact to meet us. They had arranged transportation to our hotel.
2014 08 08 07 35 022014 08 08 07 35 07
The next morning (Friday) was the day of the OUG Mexico conference. We were collected from the hotel and taken to the conference venue. Our transport had to made a number of trips to/from the conference venue to cater for all the speakers, so some of us arrived in the middle of the opening keynote by Noel Portugal from Oracle.
2014 08 08 09 32 302014 08 08 09 32 35
After lunch we had a group photo of all the speakers.
2014 08 08 13 56 07
My 2 sessions were on in the afternoon so I got to relax a bit and hang out with some of the other speakers. My first session was on Oracle Data Mine and my second session was on Oracle R Enterprise. Just like in Costa Rica I had a good attendance and again they seemed to enjoy the presentations as they were laughing along at my attempts at jokes :-)
2014 08 08 16 17 432014 08 08 16 17 42
The Mexico conference was on Friday the 8th August and this was an important day as my book was officially available that day. Just like in my previous countries I had a copy of my book to give away. Here is a photo of me with the winner.
2014 08 08 15 31 462014 08 08 17 10 57
I had the last session of the day. Some of the sessions before this had over ran and I was under a bit of pressure to finish up my last presentation by 5pm. So apologies if this presentation seemed rushed.
Also many thanks to everyone who came up to me afterwards for a chat, to have your photo taken with me and to get my autograph! :-)
Then it was time to catch a taxi to my next hotel in Mexico city centre. This would be my 6th hotel in 6 days :-(
After checking into the hotel it was time to go for dinner. Renne Antunez had invited some of the speakers to his house for dinner. These was a very enjoyable evening and for me marked the end of my OTN tour. Many of the other speakers were going to over countries over the next week.
2014 08 08 21 18 102014 08 08 22 01 432014 08 08 21 17 43
Many thanks to Renne and his wife for hosting this dinner, especially as it was Renne's wife birthday. I hope he bought her a good present.
The next morning (Saturday) I was up at 5am to get a taxi to the airport and my long long travels home, from Mexico to Newark to Dublin getting home on Sunday morning at 8am.
A big thank you to the organisers of the OTN Tour and to each of the countries that invited me to present at their conference. I really enjoyed the experiences and hopefully I can join in another OTN tour sometime soon. Also a special thank you to Vikki in OTN for sorting out all the funding and everything else.
The finals thank you goes out to my travel companions for the tour, Gorcan, Debra and Glen. Without your companionship throughout the week it wouldn't have been as much fun.

OUG Costa Rica

After the OUG Panama conference we arrived later that night in San Jose the capitol of Costa Rica. The whole emigration, luggage pick up and customs was the smoothest experiences I have ever experienced at an airport. All was done in a matter of minutes. All the booths for emigration and customs was open and staffed. When was the last time you have ever seen this before. It was a very positive start to our short couple of days in Costa Rica. We had arranged for our hotel to have a taxi pick us up and sure enough the driver was there with a good clear sign. From time of landing to being in my hotel room, which was a 20 minute drive, took no more than 1 hour.

The next morning (Tuesday) we (Debra, Glenn, Gurcan and I) headed out to do some exploring of San Jose on foot. Our first task was to get some breakfast but none of us had any local currency. Debra volunteered to use one of the enclosed ATM machines to get some money. But there was some issue with the machine and she got locked into the cubical. At the same time she got a phone call from her bank in the UK. Her ATM transaction was flagged as a potential fraudulent transaction. I most say Debra's bank was very quick to contact her and to make all the necessary changes so that she could withdraw some money. After which we had a local breakfast.

2014 08 05 09 09 28

Then we sent the next 3 hours walking around San Jose.

2014 08 05 08 25 322014 08 05 09 44 572014 08 05 17 05 56

Then it was back to the hotel in the early afternoon as the local Oracle User Group had arranged a mini bus to take us up to a hotel that was near the conference location in San Carlos. We had been told that the journey would take 2 hours. Well after 2 hours of driving up hill we were told we were only just over half ways there. It was a long long journey but the views were really beautiful. We had a 10 minute break at little village with a nice church and a really cool garden in front of it.

2014 08 05 19 03 502014 08 05 19 04 552014 08 05 19 03 00

After anther hour we arrived at the hotel, checked in, and we met up with some other presenters for some dinner. Then it was time for bed as we were being collected at 7:30am.

On Wednesday morning we got collected and taken to the conference venue which happened to be a local university. The User Group had proved a bus service from San Jose to the conference venue and there was a sizeable number of industry people mixed in with some of the university students.

2014 08 06 09 21 242014 08 06 09 22 262014 08 06 09 25 51

My first presentation was in the auditorium just after the opening keynote. This has to be one of finest rooms I've seen and presented in. Even better we had a HD projector. This has to be a first, so I had no resolution issues with running my VMs. I had a really good turn out for my presentation and the photo below shows only some of those who attended.

2014 08 06 10 00 09

In the after noon I had my 2nd and 3rd presentations. For my last presentation all the seats were taken and there was even some people standing. There was a lot of people who came to all my presentations which I was delighted with.

2014 08 06 13 09 572014 08 06 15 55 252014 08 06 15 55 26

After my last presentation I had a raffle for a copy of my book. There seemed to be a lot of interest in this :-). Here is a photo of me with the winner of the book and someone else who was having a read of it afterwards.

2014 08 06 16 59 472014 08 06 17 17 18

This was a very enjoyable conference and the attendees at my sessions were laughing at some of my jokes or maybe they were laughing at me. Anyway I took it that they were enjoying my presentations. For the first time, I had people come up to me after my presentations to have their photography taken with me and to ask me for my autograph.

Here is a picture of the Oracle ACE Directors who presented at the OUG Costa Rica conference.

2014 08 06 17 30 38

We were told that our bus journey the day before was the scenic route so that is why it took 3 hours. As soon as the conference was finished we got back on the mini bus to be taken back to our hotel in San Jose. Theoretically it should have been a much quick journey as we were going back the quickest route. This time it took 2 hours 40 minutes.

On Thursday at 2:45am we were woken by a 4.7M earth quake. The room was shaking and everything was shaking in it including me. After breakfast on the Thursday morning, Debra had arranged for us to go on a tour of a Coffee plantation and factory. This coffee tour was hilarious and the best tours I have ever been on. Our tour guides were a comedy double act :-)

2014 08 07 09 42 482014 08 07 09 51 042014 08 07 10 09 56

After the tour it was back to the hotel and to get our taxi out to the airport. Did I mention how well operated the airport was. How often have you gone through security when all of the scanners were in operation and fully staffed. This meant that there was almost no queue and I was through security in no time at all. From check in to the departure gate took about 2 minutes.

Our (Glen, Debra, Gorcan and I) next stop was Mexico

OUG Panama

The OTN Tour of Latin America has come to an end and I was very lucky to have been a part of Northern part of the tour.

My OTN Tour consisted of visiting 3 countries in one week and giving 8 hours of presentations. This blog post looks back at the OUG Panama conference and I'll have separate blog posts for each of the other countries.

My travels stared the Saturday before the OUG Panama conference which was on Monday 4th. My flights consisted of flying from Dublin to Newark and then onto Panama. All of that seemed to go smoothly until I reached Panama. After passing through emigration I was then in a very chaotic baggage hall. After about 1 hour of searching for my suit case I sought help from the airline. They were able to tell me that my suitcase was scanned off in Panama. So after another 30 minutes of searching for the suitcase with airline staff, there was still no sign of it. So a lost suitcase report was filed and off I went to meet the person who was collecting me from the airport. But there was no sign of them. I managed to find some wifi and sent a few messages looking for help and how could I get to my hotel. I got a quick reply and and 45 minutes later I was on my way to the airport.

This is the 3rd time that this particular airline has "lost" my suitcase.

I was very glad to reach the hotel but I had no change of cloths or toiletries with me :-( For all future travels that involve a flight change I will be packing some of these in my hand luggage.

On the Sunday morning, after several hours trying to contact the airline, I finally got approval from them to buy some items. It was then time to meet up with Gurcan Orhan and we headed out to explore Panama city on foot (and to buy me some things). We spent about 3 hours walking around exploring Panama city where we say lots of differences in living standards right beside each other. Then it was back to the hotel as the local user group had arranged a tour for us.

Our tour guide and one of the helpers for the user group was Melin took us to see the Panama canal, the old town and lots of other areas of Panama. We finished of the evening with a dinner in a traditional Panama restaurant. On getting back to the hotel my suitcase was there :-) but no communication from the airline about what happened.

2014 08 03 14 50 322014 08 03 16 17 072014 08 03 17 45 44

On the Monday morning I met up with Gorcan, Debra and Glen who were to be my travel companions for the week. There was a bus arranged to pick us up from the hotel and off we went to the conference venue which was in one of the Universities in Panama. We arrived at the venue very early and not many knew about the conference or where we should go. After a while we worked it and found the conference location.

2014 08 04 08 52 082014 08 04 15 10 56

Many thanks to the User Group in Panama for inviting us and for all the arrangements. There was plenty of helpers on hand.

My 3 sessions were not on until the afternoon so I hung out in a session by Gurcan and also one by Dan Morgan. Then a bit of hanging around with the conference people and talking about some Oracle tech stuff. For my 3 sessions I completely over ran on my first session and then for the last 2 sessions I was playing catchup. Especially for the last presentation as there was a bus booked to take us to the airport at 4pm. So I basically ran out of the presentation and straight into the bus to the airport. But before I did that I was able to give away the very first copy of my book. It wasn't released yet (it would be on the 8th Aug). I had a raffle for everyone who attended my sessions and here is a picture of me with the lucky winner.

2014 08 04 16 21 35 2014 08 04 08 46 19

We arrived at the airport, with a minor detour via the hotel, with lots and lots of time to spare for our flight. Our next location was Costa Rica.

my Oracle Data Miner Book

Some of you may be aware that I have been writing a on Oracle Data Miner. Actually the book covers the Oracle Data Miner GUI that is part of SQL Developer, the SQL and PL/SQL functions, procedures and packages that form the Oracle Data Mining option in the database and lots of other topics for the DBA, Developer and BI/DW people.
Today is a bit day for this book as it is officially released and available for purchase. See below for some links to where you can but the book in print and e-book formats. It has been published by McGraw-Hill/Oracle Press.
The book is aimed at a variety of people and the aim of the book is to introduce them to using the Oracle Data Miner tool and how to perform various data mining and predictive analytics tasks using SQL and PL/SQL.
The book will not teach you about how each of the data mining algorithms works. There is a bit of an assumption that you know a bit about these already. There are lots of books and resources about that cover that material. You can look on my book as an getting start / how to use type of book.
Below are are the images of the front cover and the back cover.
Book Cover            Book Back Cover
For more details of the book and for some updates keep an eye on my ODM Book page. On this page I'm adding a FAQ secion. This will be based on questions that I receive about the book.
If you buy the book then I hope you will find it helpful. If you are going to attend one of my presentations at an Oracle User Group meeting then bring the book along and I can sign it for you. Alternatively if you are at Oracle Open World 2014, come along to the Oracle Press Book Store, as I will be there to sign books on Wednesdays 1st October between 13:00 and 13:30.
Where can you Buy my Oracle Data Miner book (print and e-book).

Oracle Magazine-November/December 2000

The headline articles of Oracle Magazine for November/December 2000 were on how application service providers are changing the way that business operate, everything from project management collaboration, professional services, online marking and how to go about becoming one.

Ora mag 2000 nov dec

Other articles included:

  • Tom Kyte has an article on how working with Java is simpliernow that it is a native part of the Oracle database. He gives some examples of how to get some of the typical DB information and processing the results.
  • Oracle backs the development of a Common Warehouse Meta-model. This is and XML based metadata standard that was developed by the OMG. This will allow the exchange of e-business information and hopes to accelerate a company's ability to move from data to decisions..
  • There was a number of articles on the Oracle Internet Platform, how it all works and its various parts. These articles helped to support the article on the application service providers.
  • Doug Obeid gives a good introduction article on the Secure Sockets Layer(SSL). He looks at securing transmissions, cryptography, authentication, various protocols and messaging.
  • The part 2 of the article on Indexing Oracle 8i interMedia for managing and deploying rich data on the internet.
  • Locally Managed Tablespaces looks to explain how the DBA can setup and manage tablespaces, so that the amount of space required can be minimized.
  • Steven Feuerstein has an article on using Native Dynamic SQL using DBMS_SQL.
  • Following up on previous articles (in previous editions) we have another article on how to go about analysing the Statspack Report. Statspack came with release 8.1.6 of the Oracle Database. The Statspack report is extremely useful for analysing and monitoring your database.

Tokenizing a String : Using Regular Expressions

In my previous blog post I gave some PL/SQL that performed the tokenising of a string. Check out this blog post here.

Thanks also to the people who sent me links examples of how to tokenise a string using the MODEL clause. Yes there are lots of examples of this out there on the interest.

While performing the various searches on the internet I did come across some examples of using Regular Expressions to extract the tokens. The following example is thanks to a blog post by Tanel Poder

I've made some minor changes to it to remove any of the special characters we want to remove.

column token format a40

define separator=" "

define mystring="$My OTN LA Tour (2014?) will consist of Panama, CostRica and Mexico."

define myremove="\?|\#|\$|\.|\,|\;|\:|\&|\(|\)|\-";



                 REGEXP_SUBSTR( '&mystring'||'&separator', '(.*?)&separator', 1, LEVEL )

                           , '&separator$', ''), '&myremove', '') TOKEN




    REGEXP_INSTR( '&mystring'||'&separator', '(.*?)&separator', 1, LEVEL ) > 0




When we run this code we get the following output.

Token fun 3

So we have a number of options open to use to tokenise strings using SQL and PL/SQL, using a number of approaches including substring-ing, using pipelined functions, using the Model clause and also using Regular Expressions.

BUCKET_WIDTH: Calculating the size of the bucket

Some time ago I had some blog posts introducing some of the basic Statistical function available in Oracle. Here are the links to these.

Most people do not realise that Oracle has over 250+ statistical functions that are available (no addition cost) in all the database versions.

I've had a query about one of the functions BUCKET_WIDTH. The question was wondering if it was possible to get the width of the bucket in each case. There does not seem to be a build in feature to get this value, so we have to calculate this ourselves.

Here is an example of how to calculate the bucket width, as on the example I used in my previous blog post.

SELECT bucket, max(age)-min(age) BUCKET_WIDTH, count(*)

FROM (SELECT cust_id,



                         (SELECT min(age) from mining_data_build_v),

                         (select max(age)+1 from mining_data_build_v),

                      10) bucket

          FROM mining_data_build_v

          GROUP BY cust_id, age )

GROUP BY bucket

ORDER BY bucket;

Bucket width

What this query gives is an approximate value of the size of the Bucket Width based on the values/records that are in a bucket. The actual values used cannot be determined exactly as there is not function/value in SQL that tells us the actual value.

Tokenizing a String

Over the past while I've been working a lot with text strings. Some of these have been short in length like tweets from Twitter, or longer pieces of text like product reviews. Plus others of various lengths.

In all these scenarios I have to break up the data into individual works or Tokens.

The examples given below illustrate how you can take a string and break it into its individual tokens. In addition to tokenising the string I've also included some code to remove any special characters that might be included with the string.

These include ? # $ . ; : &

This list of special characters to ignore are just an example and is not an exhaustive list. You can add whatever characters to the list yourself. To remove these special characters I've used regular expressions as this seemed to be the easiest way to do this.

Using PL/SQL

The following example shows a simple PL/SQL unit that will tokenise a string.


    vDelimiter VARCHAR2(5) := ' ';

    vString    VARCHAR2(32767) := 'Hello Brendan How are you today?'||vDelimiter;

    vPosition   PLS_INTEGER;

    vToken     VARCHAR2(32767);

    vRemove    VARCHAR2(100) := '\?|\#|\$|\.|\,|\;|\:|\&';

    vReplace   VARCHAR2(100) := '';


    dbms_output.put_line('String = '||vString);





    vPosition := INSTR(vString, vDelimiter);


    WHILE vPosition > 0 LOOP


       vToken := LTRIM(RTRIM(SUBSTR(vString, 1, vPosition-1)));

       vToken := regexp_replace(vToken, vRemove, vReplace);


       vString := SUBSTR(vString, vPosition + LENGTH(vDelimiter));

       dbms_output.put_line(vPosition||': '||vToken);

       vPosition := INSTR(vString, vDelimiter);





When we run this (with Serveroutput On) we get the following output.


A slight adjustment is needed to the output of this code to remove the numbers or positions of the token separator/delimiter.

Tokenizer using a Function

To make this more usable we will really need to convert this into an iterative function. The following code illustrates this, how to call the function and what the output looks like.

CREATE OR replace TYPE token_list





                                     pDelimiter IN VARCHAR2)

RETURN token_list pipelined


    vPosition       INTEGER;

    vPrevPosition   INTEGER := 1;

    vRemove         VARCHAR2(100) := '\?|\#|\$|\.|\,|\;|\:|\&';

    vReplace        VARCHAR2(100) := '';

    vString         VARCHAR2(32767) := regexp_replace(pString, vRemove, vReplace);



       vPosition := INSTR (vString, pDelimiter, vPrevPosition);

       IF vPosition = 0 THEN

          pipe ROW (SUBSTR(vString, vPrevPosition ));



          pipe ROW (SUBSTR(vString, vPrevPosition, vPosition - vPrevPosition ));

          vPrevPosition := vPosition + 1;

       END IF;




Here are a couple of examples to show how it works and returns the Tokens.

SELECT column_value TOKEN

FROM TABLE(tokenizer('It is a hot and sunny day in Ireland.', ' '))

, dual;

Token fun 1

How if we add in some of the special characters we should see a cleaned up set of tokens.

SELECT column_value TOKEN

FROM TABLE(tokenizer('$$$It is a hot and sunny day in #Ireland.', ' '))

, dual;

Token fun 2

OTN Latin America (North) Tour 2014

For a few years now I (and I'm sure you have too) have heard about and followed the various Oracle User Group tours that OTN arranges/facilitates. A tour consists of a number of Oracle User Groups in a region coordinating together to have their conferences organised so that they can get speakers from across the world to come and present.

For most presenters it involves lots of travel. So instead of them doing all that travelling to present at one conference, they can now extend their travels a little and present in a number of countries. Most of the speakers are Oracle ACE Directors and OTN is very generous with their support in that they pay for all the flights, transportation and hotels. Without the generous support of OTN these tours and perhaps many of the conference would not take place.

With envy I used to follow the various speakers on tweeter as they talked about their travels from country to country and their experiences of meeting the people and exploring the various countries. Yes their time in each country seemed to be limited but they always got to see and do so much.

Earlier this year there was an call for presentations for the various OTN Tours in 2014. I submitted 3 presentations that coverd Oracle Advanced Analytics Option (Oracle Data Mining and Oracle R Enterprise). I thought I didn't stand a chance given the speakers that have participated in previous years.

A couple of weeks ago I received an email saying that I had been accepted onto the OTN Latin America (North) Tour. So you can imagine my excitement. The full OTN Tour North leg covers a number of countries across central and south America and is over a 2 week period. Unfortunately I'm not able to be away for that long, so I was accepted for the conferences on the first week of the tour. This will include Panama, Costa Rica and Mexico :-)

Some of you might think this is a bit of a golly and a holiday. What I've discovered over the past week or more is that it will be far from that. There is a lot of work in preparing the presentations, giving the presentation, setting up live demos between presentation, various meetings with people at the conferences etc etc etc. Then there is all the travel, all the airports, all the airport transfers, all the overnights in hotels. Over the course of 7 days I will be staying 6 different hotels.

I have spent the last week just trying to arrange my flights and hotels. This also involved trying to coordinate with other speakers so that we can travel together as much as possible.

Here are the dates and the presentations that I will be giving at these conferences:

4th August : Panama (in Panama City)

     10:00-11:00 : Getting Started with Oracle Data Miner & Predictive Analytics

     11:00-12:00 : Combining the Power of R and in-Datbaase Data Mining. Running R in the Database. Seriously!

     13:00-13:40 : Sentiment Analysis Using Oracle Data Mining

6th August : Costa Rica (in San Carlos)

     10:00-11:00 : Getting Started with Oracle Data Miner & Predictive Analytics

     13:00-14:00 : Sentiment Analysis Using Oracle Data Mining

     16:00-17:00 : Combining the Power of R and in-Datbaase Data Mining. Running R in the Database. Seriously!

8th August : Mexico (in Mexico City)

     14:00-15:00 : Getting Started with Oracle Data Miner & Predictive Analytics

     15:00-16:00 : Combining the Power of R and in-Datbaase Data Mining. Running R in the Database. Seriously!

When the agenda for the conferences are available I will have another blog post with their details.

If you are at one of these conference do please say hello :-)

I've finally booked all my flights and hotels. Many thanks to my fellow ACE Director presenters for your research and sharing of travel plans. It looks like there will be a groups of us all travelling together.

Now the next challenge is to prepare the presentations and live demos (yes live demos).

I hope to blog about each of the conferences and my travels to/from each country. It really depends on what time I will have and access to the internet. Perhaps this is something I will try to do on my various plane flights or waiting at the airports. So watch out for these :-)

Updated with some stats on my travels

My travel plans for the OTN Latin America tour of user group conferences involves

  • 12,200 flying miles,
  • 29.75 of flying time,
  • way too many hours hanging around in airports
  • over 8 days
  • staying in 6 hotels
  • plus 1 over night flight,
  • giving 8 hours of presentations in 3 countries

Why do we do this? Because we love sharing with the Oracle User Groups around the world. I'm only doing 1 week of the tour. Some people are doing 2 weeks :-(
