My Oracle Life of Clubbing & Harmony March 31, 2015

Last year I promised myself I would do more conferences & presenting and that it would include more events further afield, such as in Europe. I can’t say I managed it in 2014 (Liverpool for the UKOUG Tech14 did not count as a foreign country for me, even if I found a couple of the locals hard to understand) but 2015 is proving more successful. I attended the OUG Ireland conference 2 weeks ago, for my first trip to that country, and I learnt recently that I have papers accepted for Harmony 2015. This conference is a joint event between the Oracle user group of Finland, the Oracle user group of Estonia and the Latvian Oracle user group.

The conference is on the 11th and 12th of June in Tallinn, Estonia. I know that a few of my friends I’ve met in the flesh will also be there but also some people I only know online and who I’m looking forward to meeting for real {and one who I am not sure if I have met in the flesh or not!!!}. That’s part of why I like going to conferences; It is nice to get to know people via electronic means but there is nothing like actually being in the same room and chatting, especially if it is relaxing over a coffee, beer or a meal.

However, I am particularly happy to be going to Tallinn as my wife has been there and loves it. We are trying to organise it so that she can come over as well, but she has her own travel commitments that vary from week to week. Sue knows how to say “can you punch my ticket” in Estonian – and she assures me this is not a euphemism for anything.

In case Sue cannot make it, she has given me the book she learnt from, so I can learn Estonian myself:

Learn Estonian - in Russian!

Learn Estonian – in Russian!

First I have to learn Russian though… Yes, it’s a Russian “How to learn Estonian” book.

Have you any idea how much pleasure she took in doing that to me?

So that is the Harmony. What about the Clubbing? That would be Club Oracle London, which is a user group I mention each time there is a meeting. It is in London in the evening and there are 3 talks, beer, pizza and lots of chat between the crowd & the presenters. I’m doing my Disasters talk at the next meeting on the 30th April. Click that link to register and secure your place, it’s free. The other presenters are Svetoslav Gyurov and Dominic Giles. Dom is being particularly brave and is offering to answer any questions people have about the database {“as honestly as I can”}. I’ve known Dom for years, he used to come over to the place I worked when we were doing a lot of beta testing of Oracle. He secured his place in my admiration by not only thoroughly knowing his stuff but also when he told me off for being pathetic and not pushing the new tech and that I was being a wimp. Utter honesty from the vendor works for me.

I’ve currently got nothing else organised for 2015 conference-wise (apart from the small issue of helping define the technical content for UKOUG Tech15! So I guess I will be there. Oh, and probably a couple of SIGs). I keep saying I’ll try to do Bulgaria but again I’d like to get that to work with going with Sue. And of course, I could put in for Oracle Open World 15, but it’s a loooong way to go and costs me a lot. And Larry does not seem to want to talk to me anymore.

Who Plans The Content of UKOUG Tech15? March 26, 2015

<<…Overview of what the Tech15 volunteers don't do

When you go to a conference like UKOUG Tech15 there are hundreds of talks given over several days and a dozen or so streams. Who decides what is presented and how do they decide?

You do. Well, I’d say you have about 60-70% of the input, if you are a member of the UKOUG (and I know many reading this are not – but you are probably members {via your employer, if not personally} of other user groups. And, if you are not, you can probably benefit from joining one.) The point is, the members of the UK Oracle User Group have a fair say in what gets talked about at the UKOUG conferences. And, though not all are run in the same way, I know several of the large oracle conferences run on similar principles. You also provide the raw material, the proposed talks. That is open to each and every one of you, member or not. Anyone can offer a talk.

What about the other 30-40% of the input? Well, that would be me :-). {Note, British ironic humour}. As I mentioned in my first post about organising Tech15 I am the Lead for the database area this year, and some people did blame me last year for the content – but being the Lead does not put me in charge. There is a technical committee that decides what they feel should be the overall structure of the conference and have the final 30-40% say in what talks are given.

I’ll go into more details about aspect of the paper selection process in future posts, but the general structure is thus:

  • The steering committee meet for a kick-off meeting and decide on:
    • Who is in which committee (though this is pretty much sorted out before the meeting).
    • the general structure of the event – The major areas (Database, Middleware, Development, Business Analytics and Hardware/OS/Engineered), the number of streams each major area gets each day, the length of sessions and if anything is happening outside the main 3 days of the conference.
    • How we handle the labeling of topics in our streams (endless discussions there!).
    • Topics and considerations that we feel are important to our streams that should be mentioned in the call for papers.
    • How we will run the sub-committees and overall committee – again, this is generally known but we look at what we learnt the prior year and change accordingly.
  • The call for papers goes out (it will be the 13th April to 10th May this year). This is advertised by the UKOUG, being sent to previous paper submitters, the User Group members and is announced in the UKOUG mailings, tweeted and several other avenues. The committee will have suggested areas to submit for, but what is submitted is up to the presenting community – and this can alter our thoughts on content.
  • Judging – From 20th April to close to the Agenda Planning Day, volunteers and members of UKOUG are asked to judge the paper abstracts. These scores are important for the next step…
  • Agenda Planning Day – the steering committee members get together and spend pretty much a whole day reviewing the abstracts, the judging scores, the slots available, what we know of the speakers and presentations, the spread of topics, percentage of established and new speakers and half a dozen other things to come up with the rough agenda. It’s a bit of a bun fight, but we get there in the end. Every abstract is looked at along with it’s judging score.
  • Speakers are informed if their papers are accepted, rejected or we would like them as reserves – and the speakers confirm or decline acceptance or reserves (and occasionally question rejections). Sometimes a speaker will be asked if they would modify a submission.
  • The technical committees may well try and source some papers where we feel a topic is under-represented or to fit with some other aim (like a stream at a given level).
  • Reserves are slotted in to replace any speakers who decline and any clashes, alterations and agenda tweaks are dealt with as they arise.
  • The agenda is launched (ie we say what is on it) mid July.
  • From the agenda launch to the start of the conference, any paper changes are handled as they come up – usually a speaker pulling out or needing to change dates but occasionally other issues.

Why is it called “Paper Selection” when people are talking? Why do we talk about abstracts? Well, conferences pretty much started off as scientific conferences and you would submit you scientific paper – and then read it out to the conference. The abstract is a brief “why you should read my 35 page argument with long, impressive words for why I think hyaenas are more closely related to cats than dogs” {they are}. We inherit those terms.

So you can see that the steering committee has a fair input, so how do WE get chosen? Fundamentally, it is via a call for volunteers from the UKOUG community. The UKOUG ask people to volunteer in their regular emails to members/volunteers. (Volunteers have to be members of the UKOUG but the membership may well belong to a company. The UKOUG keeps track of the nominated contacts for an organisation, who are responsible for the membership management, but also the individuals who have helped out at any time under that membership. As an example, someone in purchasing or HR may be the nominated contact for the memberships a company has with UKOUG, but it is members of the technical IT staff who come to the events and may start helping out).
The office UKOUG staff/board members may well ask one or two of the experienced volunteers known to them to take a lead and help chose which volunteers to accept. Or, more commonly, to go and pester people they know to step up and volunteer! New volunteers are always part of the mix, we recognise that without new people and perspectives we will stagnate, and they challenge us when we say “we always do it this way”.

I have not mentioned Oracle Corporation involvement. Strictly speaking, people from Oracle are not volunteers and are certainly not members. They are Oracle Liaisons. The UKOUG gets good support from Oracle, we have talks from them, we have some SIG meetings in their offices. Oracle Corporation of course is happy to talk about the latest/greatest aspects of Oracle and if they can get us all fired up for an extra cost option, so much the better for them. But the relationship is generally balanced and varies over the years – and is influenced by individuals. Some people who work for Oracle will push to be allowed to help out the UKOUG, some product managers are more than happy to come and give talks about free, standard or old features as well as the shiny new stuff. Others I am sure see us as an annoyance. The input we get from the Oracle Liaisons is very helpful and appreciated – but don’t think it buys acceptance of whatever Oracle Corp want. I had to help deal with an Oracle product manager last year who was upset that their area had very few talks. It got as far as them almost demanding some slots. However, the number of talks submitted and the poor judging scores for those few that were told us on the committee that the user community were not currently interested in that topic. So no talks. Faye and I talked it over, I gave the logic and reason and she was good enough to then deal with Upset Product Manager.

I have helped with the agenda planning day a couple of time – I think I got pestered to help way back in 2007 or 8! – and I have been a SIG chair and deputy chair as well as a regular presenter, so I am a known soft-touch for helping the UKOUG. A key aspect to my being the Lead is simply that I have more free time than most other volunteers, so I can be got hold of and can spend a bit of time thinking about things and making decisions. This can be important on the run-up to the actual event as you sometimes need to make decisions quickly and a group discussion may not be the best way to do it. I might check with a couple of others (and I usually do) but the key thing is to make a decision in the timeframe allowed.

So that is who the Agenda Planning committee are and where we fit in. We are volunteers, filtered and guided by some old hands but with new blood each year. We aim to guide and give structure but the talks submitted are what anyone wants to submit. Judging scores by the community are key to paper selection and though Oracle Corp supports they don’t get to dictate.

And if all else fails, blame the committee Leads.

Extra session at OUG Ireland – Oracle Lego. March 12, 2015

add a comment

I’m now doing a second session at OUG Ireland 2015. {This is because one of the accepted speakers had to drop out – it sometimes happens that, despite your best intentions, you can’t make the conference and it is better to let them know as soon as you can, as they did}. This will be a talk called “Oracle Lego” and it is one I put together a couple of years ago when I decided to try and do more introductory talks – talks aimed at those who are not {yet} experts and who I think tend to get ignored by most conference and user group agenda. So it is aimed at those new to oracle or experts in other areas who have never really touched on the subject.

“Oracle Lego” is about the basics of database design. I have a personal soap box I occasionally get on that very little real database design seems to occur these days. There are exceptions, but often the database design seems to be a quick brain-dump of what the developers or business analysts know they need to store information about and the first-cut set of tables gets created – and then endlessly modified as the development rolls on.

Guess what, we don’t build houses, cars, ships, bridges or garden sheds like that – and there is a reason. If you build things piecemeal as you go along and with bits you either have to hand or have to quickly get, you end up with a pretty poor shed. In fact you don’t end up with a shed, you end up with a shack. With a leaking roof and a door that hits the potting table when you open it. I don’t want a shack and I never, ever want to go over a bridge or sail in a ship built “on the hoof” like that!

Further, just as with a proper architectural or engineering design, a database design does not fix the solution in stone, there is still scope for modification. A bespoke house plan gets tweaked and modified as you do the build and you realise what can be improved when you see it – but you do not suddenly decide to dig out a basement and change from wood walls to stone when you have already constructed the ground floor! I’ve seen database “designs” like this.

There is also more to doing a database design than coming up with tables that hold the records we want to store: We might want to consider if storing similar things in the same table could be better than a table for each “type” of something; How we index those tables and relate them together can have a huge impact on how easy it is to get the data out and store it in the first place; The expected volume and life cycle of the data may require us to consider eg archiving; The very-much-ignored aspect of physical placement of data and clustering of data.

You can spend weeks dedicated to learning about database design – but you can also learn a lot in 60 minutes, ie the basics. And it really is like Lego – once you know the basics you can build up a really complex design. And you learn stuff doing it (and turning it into a real system), just like you do the first time you build a Lego robot (or dog or house or car or bridge or spaceship or whatever). So the second time you build your Lego robot you use the same design basics and layer on top what you learnt last time.

So that is the aim of this talk, the basics of database design.

The strange thing is, last time I did this talk I asked the audience how much database design they did. Every single one of them was already an experienced and capable database designer! So why had they come to this intro talk? They had three reasons:

  1. It was the only talk on database design at the conference, and one more than they were used to getting.
  2. They had picked up their database design skills on-the-job and thought a “reminder” of the basics would be good.
  3. It was cold outside and all the other talks appealed less.

So, this time I am hoping some of the audience is new to database design and I get to teach them great stuff they did not know. If it is all experts again, I think I’ll have to retire this particular intro talk, at least for conferences.

As you can see from the agenda grid here, I’ll be talking at 10:15. You can’t link to an abstract of the talk yet, that just needs to be twiddled into place.

Update – Peter Scott stopped by this blog and it prompted a thought. He felt it was too much at a tangent to add as a comment but I felt it was a very valid and valuable point – so check it out over here on his blog.

BTW Pete has started blogging more, on his thoughts and opinions on Data Warehousing. Personally I think it is worth catching them.

{Oh, and in case any lawyers stop by, “Lego” is of course the copyright name of a popular plastic construction toy, made by the Danish company The Lego Group, that children love playing with and adults hate walking on in bare feet. Did anyone not know that?!?! I have no link to The Lego Group and no plastic bricks will form part of my talk.}

Do you want to know what Oracle conferences are run, where they are and when? Do you present (or are thinking of presenting) and want to know when the call for papers is open?

Then go and look at Jan Karremans’ excellent page on oracle conferences.

It lists most (all?) of the European and US conferences and is a really useful reference – I’ve not come across a similar, maintained list. The below is a static screen shot of part of the list, current of today – but visit the page to see the full, maintained list.

Jan's conference list

If you spot that a conference you know about (or are helping organise!) is missing, then Jan is happy to be contacted via the page and he will add the details.

Return of the Disasters – OUG Ireland 2015 February 23, 2015

In just under a month I’ll be off to Dublin for the 2015 OUG Ireland conference. It takes place on Thursday the 19th of March. I’m doing my favorite presentation to present, on I.T. disasters I have witnessed and what you can learn from them (so now the title of this blog makes sense and maybe is not as exciting as it suggested). It is also the talk I get most nervous about doing. I tend to put a bit of humour into any presentation I do but if it is predominantly a technical talk, it’s fine if the humour falls flat. When I am intending to be entertaining, as I do with this one, there is more at stake!

not_the_best_thing_to_drop

Back in the mid-2000’s I used to do this talk once or twice a year but these days it tends not to get accepted for conferences. I suspect it is partly as I had done it a good few times and partly as it is hard to place it under the categories Oracle Technical conferences have. Is it technical? Is it project management? Is it entertainment? It is actually a bit of all of them. They are all true stories and each one highlights how we should not do things, be it some of the pitfalls of project management or where disaster tolerant hardware turned out not to be.

I’ve mentioned this presentation a couple of times in my blog. Once early on in 2009 when no one came by here very often, where I go into why I toned down the talk {concern over impact on my career/perceived professionalism} for a while and the impact of that decision {a bland and rather poor talk}. It crops up again in a post in 2013, which I think is the last time I gave this talk. I am not sure I did a very good job of it then either, as I was not well during that trip (not helped by rough seas but I was ill for other reasons). Thus I am looking forward to giving it another airing and, as I no longer worry too much about the career, I might just let rip a little more. I have a few more disasters under my belt since I originally wrote the talk, so I might include one or two of them…

The OUG Ireland conference itself is a fair-sized event, running from 09:00 to 17:30 or so, with 7 concurrent tracks covering Applications, Cloud, BI, Database and Development. I’m astounded by the number of Oracle Aces, Oaktable members and other top knowledge sharers who will be presenting {Update – Brendan Tierney has put together a list of all ACEs presenting}. I’ll have several hard decisions about which talk I go to at any given time. I’ll certainly be at Maria Colgan’s Tech keynote at the end of the day though, I’m hoping for another offer of a date* ;-).

To my shame, I have never been to Ireland before and it’s only just over there {points West}, about 90 minutes by plane. So I am turning up Wednesday lunch time and staying to late Friday afternoon so that I can look around and spend some time with fellow presenting friends (and anyone else who I bump into).

All in all, it is a trip I am greatly looking forward to for various reasons. If you can get along I encourage you to do so. And, if you are there and see me around, come and say “hi”.

{* Note to lawyers, this is an in-joke}.

Learning for free – UK User Group Meetings Coming Up February 20, 2015

There are a few user group meetings coming up in the UK over the next week or two.

Note, you need to register to attend any of these, follow the links.

First is Club Oracle London, which are evening sessions held in London with 3 talks plus free beer and pizza. The next meeting is Thursday Feb 26th at 103a Oxford Street, kicking off at 18:30. You can register for this free event here and also see more details. In brief, Simon Haslam is talking about Oracle Database Appliance, Martin Bach on 12C new features the marketing guys don’t push and finally Phil Brown giving a virtualisation case study, how NOT to do it.

On the 3rd March there is the 8th meeting of Oracle Midlands – again an evening event but this one is in Birmingham. Again, it’s free and samosas {lots of samosas!} turn up half way through to keep you going. Held at Innovation Birmingham near Aston University, there will be Chris Saxon on using Edition Based Redefinition to release PL/SQL to busy systems (ie the PL/SQL code is constantly being executed) and Tim Hall talking about Pluggable Database and why this new feature can “break” things. Tim is good enough to say how you fix the broken (I wonder if the single logwriter will crop up?). They give away some free stuff too!

Finally, on the 4th March and back in London there is the next next UKOUG RAC, Cloud, Infrastructure & Availability SIG. Bit of a mouthful that but we can’t come up with a snappy name that covers the remit of the SIG. We are trying a new format for this SIG, inspired by the two above events. We still have a full-day’s-worth of content but we start at 15:00 and go on into 20:00 in the evening. We hope that this will allow more people to attend without feeling they need to lose the whole working day to it. NB this event is free to UKOUG members but you can pay to come if you (or usually your employer) are not a member. We have talks by Jason Arneil on 12C ASM, Dave Burnham talking about free text searching, David Hickson presenting on linux OS resource management and Jamie Wallis from Oracle on TFA – Diagnostics for the Cloud. Plus a panel session where we discuss whatever you want to discuss!

I’ll be along to Club Oracle London and the RAC CIA SIG but sadly not Oracle Midlands – just can’t squeeze it in which is a real shame as it’s an excellent event.

If time, travel requirements and inclination allow, there are usually beers at a local pub after all the above where you can continue to talk about oracle stuff. Or not. It’s usually a mix :-)

Finally, a quick plug for the OUG Ireland on 19th March. This is a full, one-day conference with more speakers than I can cover, held in Dublin. There are loads of excellent presenters, many are Oracle Aces, Oaktable members and experts in their field. I’ll be there doing my favorite talk, but I’ll do a separate blog about that.

UKOUG Tech14 Suggestions for Intro Talks and My Picks of the Rest December 4, 2014

Posted by mwidlake in conference, Meeting notes, UKOUG.
Tags: , ,
1 comment so far

As I mentioned in my last post, we tried to organise a thread of intro talks into day one and two of this year’s UKOUG Tech14 conference (you can see the agenda grid here). It was not complete but I thought I should pull it into it’s own post and add in what I would recommend from the overall agenda for people who are relatively new to Oracle RDBMS.

Monday 8th

  • 08:50 – Welcome and Introduction
    • Get there in time for the intro if you can, as if you are newish to the tech you are probably newish to a conference.
  • 09:00 RMAN the basics, by Michael Abbey.
    • If you are a DBA type, backup/recovery is your number one concern.
  • 10:00 – How Oracle Works in 50 Minutes
    • My attempt to cover the basic architecture in under an hour.
  • 11:30 – All about Joins by Tony Hasler
    • Top presenter, always good content
  • 12:30 – Lunch. Go and talk to people, lots of people, find some people you might like to talk with again.
  • 13:20 – Go to the Oracle Keynote.
    • The keynote itself is shorter than normal and afterit there is a panel discussion by technical experts.
  • 14:30 is a bit tricky. Tim Hall on Analytical Functions is maybe a bit advanced, but Tim is a brilliant teacher and it is an intro to the subject. Failing that, I’d suggest the Oracle Enterprise Manager round table hosted by Dev Nayak as Database-centric oracle people should know OEM.
  • 16:00 – Again a bit tricky for someone new but I’d plump for The role of Privileges and Roles in Oracle 12C by Carl Dudley. He lectures (lectured?) in database technology and knows his stuff, but this is a New Feature talk…
  • 17:00 – Tuning by Explain Plan by Arian Stijf
    • This is a step-by-step guide to understanding the most common tool used for performance tuning
  • 17:50 onwards – go to the exhibition drinks, the community drinks and just make friends. One of the best thing to come out of conferences is meeting people and swapping stories.

Tuesday 9th

  • 09:30 Maria ColganTop 5 things you need to know about Oracle Database in-Memory Option
    • This is actually the Database technical keynote, about one of the key new technologies.
  • 10:30 Introduction to Oracle Application Express by Joel Kallman
    • APEX, as it is often called, is a simple but powerful way to develop applications. It’s probably THE most common thing that DBA-types don’t know and  wish they did?
  • 12:00 If you know any Java then Jacob Landlust on What all DBAs need to understand about JDBC Configuration or else Pete Finnigan on Secure, Review & Lock Down your Oracle Database.
  •  14:00 Chris Lawless on Zero Downtime Migrations using logical Replication
    • Good as he covers the principals of such things which teachers you a lot
  • 15:00 A bit of a struggle for a general Intro talk so I will plump for…Tim Gorman on RDBMS Forensics: Troubleshooting Using ASH as I know Tim will explain why understanding and solving performance issues is a science, not an art
  • 16:30 Tom Kyte on SQL is the best Development Language for Big Data
    • If you are new to Oracle, you pretty much have to go to at least one Tom Kyte presentation.
  • 17:30 Jonathan Lewis Five Hints for Efficient SQL
    • If you are new to Oracle, you pretty much have to go to at least one Jonathan Lewis presentation :-)

Oh, what the heck…

Wednesday 10th

  • 09:00 Jonathan Lewis Fundamentals of trouble shooting Pt1
  • 10:00  Jonathan Lewis Fundamentals of trouble shooting Pt2
  • 11:30 Tim Gorman on three types of table compression
  • 12:30 Tom Kyte More things about Oracle Database 12C
  • 14:30 Alex Nuijten Oracle 12C for developers
  • 15:30 Neil Chandler Goldengate – Migrating my first TB

 

Each year I struggle more and more to get to all the talks I want to, partly as there are so many clashes of good talks but also I end up in interesting conversations with old friends and suddenly realise I’ve missed a talk. Or my brain hits “full” and I have to take a breather.

However, my intended agenda is:

  • 08:50 Welcome and Intro to delegates prior to…
  • 09:00 Martin Bach on Oracle 12C features that didn’t make the marketing top 10
  • 10:00 Myself, HOw Oracle works in 50 minutes
  • 11:00 Coffee and recovering!
  • 11:30 Hmm, I want to go to four… Maybe Robyn Sands, Why Solid SQL still delivers the best ROI.
  • 13:30 Oracle Keynote panel
  • 14:30 Tom Hall on Analytical Functions..Or maybe Larry Carpenter on Active Data Guard…
  • 16:00 Antti Koskinen , Undocumented 11g.12c Features Internals
  • 17:00 Graham Wood, AWR: looking Beyond the Wait Events and Top SQL

Tuesday

  • 09:30 I have the pleasure of chairing Maria Colgan’s Database Keynote, Top Five Things you need to know about Oracle Database in-Memory option
  • 10:30 Joze Senegacnik, Most common Databse Configuration Mistakes
  • 12:00 Richard Foote, Oracle database 12XC New Indexing Features
  • 14:00 Damn… I’ll plump for Maria Colgan on IN-memory and the optimizer. Sorry Tim and Chris
  • 15:00 Now Tim, on RDBMS Forensics and Ash
  • 16:30 Chris Antognini on adaptive query optimization
  • 17:30 it better be Pete Sharman, hot over from Aus, doing deployment best practices for Private cloud, as I am chairing him

Wednesday

  • 09:00 Patrick Hurley, Adventures in Database Administration.
  • 10:00 Me, on boosting performance by clustering data
  • 11:30 Richard Foote, indexing in Exadata
  • 12:30 Tom Kyte, More things about Oracle 12C
  • 14:30 chairing Ganco Dimitriov on the importance of having an appropriate data segmentation
  • 15:30 Last one, 3 to chose from… Neil Chandler on Goldengate I think

Drive home and sleep

 

Conferences and the Etiquette of Meeting New People November 25, 2014

Posted by mwidlake in conference, Perceptions.

One of the reasons I like user group conferences is meeting new people in my “area” – these people at the conference not only like technology and probably some of the same technology I do but, as they are at a conference, are probably inclined to learn stuff, meet people and maybe share ideas. I’m not actually very good face-to-face socially with people I do not know, so I like to tilt things in my favour if I can!

But sometimes you have odd experiences.

I was at a conference a couple of years back that was not in the UK. I was loving it as I was meeting some people I knew electronically but never met and others who I had only met when they visited UK conferences – but most people I had no real connection to, so I was a bit quiet (yes, loud-mouthed, always-comments-in-talks me was quiet), especially as it was the first day. I was late for the lunch event, I don’t remember why, but it was a little unusual for being a sit-down meal and there was to be some meet-the-expert tables and I wanted to be able to identify some people I knew by name and never met. The big signs on tables would be a bit of a help there.

As I came in I saw half the tables were full and most of my friends were already on a full table. I wandered over to a half-full table and as I sat down I said “Hello, I’m Martin Widlake, How you doing?” or whatever to the half-dozen guys there. They all looked at me. A couple nodded or said “hi” but one said “We’ve got other friends turning up soon”. Hmm, that was code for “sod off”, I think.

I turned on the full English Accent so they could tell I was not from around those parts. “That’s nice – always good to have friends when you are at a conference….especially one where you don’t know many people?”. Some smiled, they all understood my mild reprimand. Mr Friendly who had mentioned all his other friends did not smile though. After this opening “chat” no one else really said anything more to me.

The Starter turned up and the guys all spoke to each other – and ignored me. Some other lone gun wandered up and asked me if he could sit next to me – “Sure, feel free – I’m Martin Widlake, I’m from the UK”. He introduced himself and sat down. Mr Friendly piped up “There are more people joining us at this table, I’m not sure there is gonna be room”. Some of his already-present friends had the decency to look a bit apologetic and I simply said “Well, it’s pretty full on all the tables now – and he’s got his starter” as the waitress put down a plate. And I pointedly started talking to the new chap.

Main turns up and so do a couple of late members for Mr Friendly’s group, who sat down at the remaining spare seats. “I told you” he said “you might have to move”.

I’m losing my patience a bit now. “Well they can sit somewhere else I’m sure, seeing as they are late.”

Mr Friendly is getting angry “I warned you when you sat down – when the others turn up, you’ll move”.

“I won’t move, this is my seat. I’m staying here”.

“Who the hell do you think you are?” demands Mr Friendly. Oh, thank you, I think to myself. I’m so going to enjoy this….

“Well, I did introduce myself when I arrived and….” pointing to the large sign with ‘Martin Widlake’ on it above the table “there is a large reminder of my name just there”. I paused a couple of seconds before adding “So this is my seat and my table and I’m kind of obliged to stay here, whether you want to talk to me or not”.

Maybe I could have handled the situation better from the start and stressed that the reason why I was staying was I was supposed to sit at my table. But I was smarting a little from the fact that no one apparently wanted to come to my table and talk to me. Maybe not surprising, as I don’t think I had done a presentation at the conference at that point – but my massive ego was already bruised.

So what about the etiquette of meeting people at conferences? It was just a title for a story I felt like telling…

However, there are a couple of things I do want to mention about the etiquette of meeting people at conferences. If you do not know many people there – just talk to people. People you don’t know. Just make a few observational or open comments, nothing to direct – “This queue for the coffee is a bit long”, “Have you seen any good/bad presentations yet?”, “what do you think about ansii join syntax” (OK, last one is a bad suggestion). Most people will respond and those that do not are probably just very nervous – more nervous than you! – and almost no one will be like Mr Friendly above. And if they are like Mr Friendly, where there are a few hundred other people you can go and try the odd comment on to see if you get a response.

At the social events you can see dozens and dozens of people just at the side or wandering around, not speaking to anyone. If you are one of them, few people are likely to come up to you and start a conversation (I’ve tried approaching the odd lone person but I stopped when I got Seriously Stalked at one of the UKOUG conferences). But if you go talk to other people, most of us will respond. And if someone does respond – Don’t stalk them!!! – have a conversation and then, having found it is possible, go and try some other people. The next day, if you see the people who responded last night, go and have a small chat again. But Don’t stalk them!!!.

Finally, talk to the presenters. We are actually the easy targets and not the hard ones. Those of us who present tend to be attention seekers so we are happy for you to come up and chat. And if you pretend you liked our talks we will certainly warm to you, so it’s an easy opening. However, it’s not like we are pop-stars or TV celebrities, we are just average people and you can come and chat to us (actually, I feel the same about pop-stars and TV celebrities, I don’t get easily star-struck but I know a lot of people do, even over Oracle Names).

But Don’t stalk them!!!.

And if someone insists on joining you at a table that has a name above it – listen carefully when they introduce themselves…

Conference Organisation from the Inside – UKOUG Tech14 November 20, 2014

An interesting experience I have had this year is being more involved in helping organise the annual UKOUG Oracle Technical Conference – Tech14. I fully intended to blog about things as we progressed, but it never happened got going so I did not.. But I thought it would be interesting to do a couple of blogs about it now, for anyone interested, as the conference itself approaches.

If you have never helped organise a conference or user group meeting then you probably think there is not a lot of work involved. You would be quite wrong. If you have been a volunteer at one, as in you have presented or chaired sessions, then you will have more understanding – but still probably fall short of the mark in estimating the effort involved. There is a lot involved.

The UKOUG is, I think, the largest Oracle User Group in the world and the annual conference has grown significantly since I first got involved around the turn of the millennium {which is now quite a while back – yes, we are all getting quite old}. In fact, it is now a set of conferences and events dedicated to Oracle E-Business suite, JD Edwards, PeopleSoft, Hyperion and regional conferences for Ireland and Scotland (sorry Wales) as well as the annual technical event that used to be the single conference. This year Tech14 is in the same location as Apps14, which covers most of the application areas I just mentioned. I rather like the fact we are returning to being in the same place but still have two events as it matches the reality of the two groups. There is a lot of cross-over between apps and tech for some of us whereas for many, you belong in one camp or the other. It’s a bit like do you like football or rugby…

So where did I fit into the picture? Each year the UKOUG approach some of it’s volunteers and asks them if they would mind giving them a little bit of help with the conference that year. Any that do not run away quickly are corralled into a room at head office in Wimbledon and bribed them with tea, coffee and biscuits. We are arranged into being the content committees for various areas. I was part of the committee for the Database stream and ended up being the Chair. This does not make me any more significant, it just means if someone has to make a decision when the committee is split or they just want a quick answer to a question (such as “can Dave swap his presentation slot with Senthil’s”), then it will be me the office contacts. OK, I suppose it means I have a little more input but as everything is open, others on the database committee (or others) can cry foul.

There are also committees for Middleware, Development, OS & Engineered systems, Business analytics… I am sure I have forgotten one! In many ways the Database stream is easiest as I do not think it has as broad a remit as, for example, development, and the core database is the core database. But we also have the largest community and thus the largest number of papers put forward and streams to organise.

So What do the committees do? Our responsibility is primarily to agree on the technical content of our steams. ie What presentations go into it, the order of them, plan any threads or themes to run through a day or several days and ensure that at any given time there are talks, roundtables and workshops across a spectrum of topics and not 4 all on backups or ADF. Sounds easy? No, it’s not. I’ll go into why in a later post.

We also help with decisions about wider issues for the conference – when the keynotes occur, who to ask to do the keynotes, the evening events and some wider issues like that. However, the actual location and timing of the event is set in stone before we get involved – it has to be as those major decisions have to be made over a year in advance. Personally, I think the venue at The Liverpool ACC is a good one. I can understand some people feeling Liverpool is a bit far to go but in reality it only takes an hour or two longer to get there than to what was the traditional home of the conference in Birmingham. And frankly, I was tired of Birmingham and the usual pub I ended up in was getting truly ratty and unpleasant. The ACC is at Albert Doc and a lot of bars, restaurants and ,I suspect, nightclubs (for those who like loud music and terrible lager at a premium price) are in the area.

Most of the work planning the actual conference is of course done by the office staff and I know that for smaller user groups all the work is done by volunteers – I’ve done a couple of myself too – so some of you might think we volunteers for the UKOUG conference have it a bit easy. But the conference is massive and we do {most of us} have proper jobs to do too. So if something is not as you would like at the UKOUG conference, or in fact at any conference, it is probably not through lack of effort. Just let us know {nicely, please} and we will try and not make the same mistake next time.

Audio semi-Visual Presentation on Clustering Data in Oracle November 12, 2014

I suppose it had to happen eventually but one of my presentations has ended up on YouTube. It’s a recent presentation I did for the Oracle Midlands user group in September.

The topic is (as the title of this blog post hints at!)Boosting select performance by clustering data. The video consists of the slides I presented, changing as the presentation progresses, with my audio over the top. It goes on for a bit, close to an hour, but you could watch a section and then go and do something else before watching a bit more.

I have to say, it is very odd hearing my voice (and the slight touch of the “brummie” {Birmingham} accent coming through) and I do wince at the places where I blather or say something slightly wrong or make a joke that involved a visual element that is lost. Oh well, at least you don’t see me wandering around and jumping up,literally, to point out bits on the slides.

I’m glad to say I will be repeating a slightly more polished version of the presentation at this year’s UKOUG Tech14 conference in December. I was a bit under the weather back on September the 16th, due to having just returned to the Working Life, and with this perfect example of what I did then I should be able to make the next shot at it a cracker… maybe.

On the topic of Oracle Midlands, I like this user group that is run by Mike Mckay Dirden, the meetings consist of evening presentations in Birmingham with a bit of support from Redgate. This includes half-time samosas to keep you going. The next meeting is described here and is on Tuesday 25th November. This meeting has two presentations by my friend Bjoern Rost, who is an Oracle Ace Director {gasps of appreciation from the audience} and a consummate presenter. I wish I could make it there as I would like to share a pint with Bjoern (well, he’ll have wine or a cocktail I suspect as he is not a beer fan) as well as some of my other friends up that part of the country.
