Just a quick note to say I have a new tab on the blog called “Richard Foote’s Art” where I’ll periodically upload a new piece of my art work.

As the page says, they highlight both what’s in my mind (so beware) and how I like to relax in the evenings.

All pieces are for sale for $1 Million (or nearest offer) ūüôā Actually, they’re not really, the one below has already gone to a good home.

Enjoy !!

Modify Primary Key Using Index (Learning To Fly) February 27, 2014

Posted by Richard Foote in 12c, Modify Primary Key Using Index, Oracle Indexes, Primary Key, Richard's Musings.
add a comment

One of the things I love about working with Oracle Database technologies is that there’s just so much¬†one can¬†learn. I make it an active¬†goal of mine¬†to try to¬†learn something new at work each and every day, no matter how big or small. One of these days, I might blog about a presentation I put together a while ago on the common¬†habits of highly successful DBAs (or technologists in general). One of these key habits I believe is the constant need to keep learning and to keep growing professionally.

One of the places¬†I¬†constantly turn to in order to¬†learn something new is Jonathan Lewis’s Oracle Scratchpad blog. I doubt many folks who read my blog don’t already know¬†what a fantastic source of information this is. Reading¬†a recent posting¬†of his on Modifying Primary Keys¬†was one such moment where I went “wow, I didn’t know you could do that” !!

I¬†previously blogged about¬†the new 12c capability of having Multiple Indexes On The Same Column List¬†and¬†demonstrated how it was now possible to “quickly” swap the index on say a Primary Key constraint by pre-building¬†a new index (say a Unique index to replace an existing Non-Unique index), then drop/disable the constraint and old index, make the new¬†index visible and re-applying the PK constraint.

Well, as Jonathan described, there’s an easier alternative that doesn’t require so much stuffing around with the PK constraint.

I’m¬†just going to¬†setup the same demo as I used in the initial multiple indexes discussion where I have a Non-Unique index policing the PK constraint of a table:

SQL> create table ziggy (id number, name varchar2(30))
 partition by range (id)
(partition ziggy1 values less than (1000),
 partition ziggy2 values less than (2000),
 partition ziggy3 values less than (maxvalue));

Table created.  

SQL> insert into ziggy select rownum, 'DAVID BOWIE' from dual connect by level <=5000;  

5000 rows created.  

SQL> commit;  

Commit complete.  

SQL> create index ziggy_id_i1 on ziggy(id);                

Index created.  

SQL> alter table ziggy add constraint ziggy_pk primary key(id);  

Table altered.

I then subsequently decide to replace the existing Non-Unique index policing the PK constraint with say a Unique Index instead. (Note the following also applies for Unique constraints as well). With 12c, I can pre-create another index with a different characteristic on the same column, I just have to initially make it Invisible:

SQL> create unique index ziggy_id_i2 on ziggy(id) invisible online;  

Index created.

Now comes the interesting bit (for me anyways). I can simply modify the PK or Unique Key constraint to use the new index with the USING INDEX clause:

SQL> alter table ziggy modify constraint ziggy_pk using index ziggy_id_i2;

Table altered.

And then switch the visibility of the two indexes:

SQL> alter index ziggy_id_i1 invisible;

Index altered.

SQL> alter index ziggy_id_i2 visible;

Index altered.

SQL> drop index ziggy_id_i1 online;

Index dropped.

Thereby changing the index policing the PK constraint without having to drop/disable the PK constraint in the process. I do have both indexes invisible for a brief period of time, so still exercise some caution, although the PK business rule is safe at all times without having to lock the table.

Obviously, if you wish to switch the index with one that uses a different column list (for example, if you wish to remove an unnecessary column from the policing index), then the indexes can simply be switched without having to alter their visibility attributes.

As Jonathan pointed out in his post, this capability dates back to later versions of 9i.

I wonder what I’ll learn tomorrow …

Merry Christmas !! (Love Is Lost) December 23, 2013

Posted by Richard Foote in Christmas, Kaleidoscope, Richard's Musings.

It’s been a pretty good year all round really.

I had the most perfect holiday in Hawaii, the mighty Crystal Palace¬†won promotion to the English Premier League, we’ve finally won back The Ashes from England¬†and David Bowie released¬†the most brilliant¬†“The Next Day” album right out of the blue. Oh and the Oracle 12c Database¬†was finally released as well ūüôā

Next year promises to be just as exciting with the eagerly anticipated Oracle Database¬†“In-Memory” Option due to be released sometime in 2014. I’m sure to have quite a bit to talk about on that subject when it finally gets released, considering the impact on database indexing strategies it will have¬†ūüôā

After a relatively quiet year on the conference front, I’m planning to get out a little more next year. As an example, I’m really looking forward in June to presenting at the excellent ODTUG¬†Kaleidoscope 2014 conference in beautiful Seattle. I have a couple of papers accepted so I hope to catch up with many of you there, a city I loved when I visited previously. More details to come.

Let me take this opportunity to wish everyone a very Merry Christmas and the very best of New Years. Stay safe and stay happy.

As a treat this year,¬†a¬†fantastic¬†digital art video¬†of one of the tracks from “The Next Day”,¬†a re-mixed version of “Love Is Lost” by James Murphy.

Enjoy !!

Top 100 Books Of All Time (I Can’t Read) November 23, 2013

Posted by Richard Foote in Richard's Musings, Top 100 Books.

And now for something completely different.

David Bowie recently revealed a list of his top 100 books. It was a really interesting list, especially considering that being such a huge David Bowie fan for so many years, I had only actually read 2 of the books on his list (“Nineteen Eighty-Four” by George Orwell and “A Clockwork Orange” by Anthony Burgess). So as an avid reader, this got me thinking, what would be in my list of top 100 books and thought it would be a bit of fun to compile and share my own list.

Well after lots of consideration and much dwelling back into my distant past, I’ve come up with a list of my favourite 100 books of all time. I’ve tackled this a little differently in that I’ve tried to view this from the perspective of my feelings and impressions of when I actually first read a book, rather than how I might view a particularly book now. So for example, it was the joy and excitement of a nine year old Richard Foote reading “Comet In Momminland” over a couple of dark winter evenings in Manchester that has an equal vote to the somewhat older current version.

I also decided to treat a series of books as being the one logical book, a “partitioned book” if you like, but only¬†when such a complete series deserves credit (for example “The Lord of the Rings”) but not so if the series¬†doesn’t hold up as a whole¬†(such as with the “Dune” series and the less inspiring follow-ups¬†after the brilliant original novel).

Getting to the 70-80 mark wasn’t actually too difficult but deciding which books get to fill the remaining slots was really quite tricky with various books and authors being in then out then in again. Then I remembered an important book or two which meant something else had to go. But in the end, I think the final 100 I’ve selected is a pretty good overall reflection of what I considered to be a really good read at the time.

Finally, the books are ordered alphabetically as it was just a task too far to try and order them in order of preference. However, there is one notable exception as I do have a clear favourite, that being J. R. R. Tolkien’s classic “The Lord of the Rings”. I remember as if it was only yesterday having a week off school, sick in bed with tonsillitis, when my parents bought me “The Fellowship of the Ring” to cheer me up. Not only did it cheer me up but my introduction to the land of Middle-Earth in many ways changed my life as so many fantasy based novels in my list will testify. It’s also about the only book on the list that I’ve repeated read over the years.

I guess that’s why all the books ultimately made it on the list, having helped in some way (some more than others) to mould me into who I am today. That and considering them a damn fine read at the time¬†of course.

So here they are, my top 100 books of all time. I wonder how many you’ve read¬†ūüôā

OTWUK13 (Battle For Britain) November 14, 2013

Posted by Richard Foote in OTWUK13, Richard's Musings.

I’ve been fortunate to attend and present at many Oracle conferences over the years but the one I would love to get to one year is the UKOUG conference. It always seems to have a great line-up of speakers and I’ve heard lots of positive feedback. Unfortunately, it’s a long long way from home, but it might be a good way to get to also see my beloved Crystal Palace football team live in action ūüôā

For those attending this year, there’s a extra treat in that running in parallel literally across the road will be the OakTable World UK 2013 conference. It has a fantastic line-up of speakers including:

James Morle
Jonathan Lewis
Alex Gorbachev
Iloon Ellen-Wolff
Niall Litchfield
Doug Burns
Joel Goodman
Marcin Przepiorowski
Christian Antognini (now the latest Oracle ACE Director)
Pete Finnigan
David Kurtz
Moans Nogood

The event is free to all those attending the UKOUG conference but you need to register here first.

Maybe next year I’ll finally have a crack at getting to the UK and attending …

1,000,000 Blog Visits (How I Made My Millions) April 30, 2013

Posted by Richard Foote in Richard's Musings.
add a comment

Things have certainly been busy lately so I haven’t had much of a chance to get back here for a while. Busy at work, busy at home, busy at play and even busy with a new David Bowie album to enjoy !! And yes, “The Next Day” is an absolutely stunning album by the great man ūüôā

While answering a backlog of questions today however, I noticed the blog has recently just passed a rather significant milestone. A little like driving the car and being too busy listening to David Bowie on the stereo to notice that the odometer has just passed 200,000 kms (yes my car is getting on a bit), I missed out on seeing the blog visit counter go past 1,000,000 visits. I kinda get excited by these milestones, see how I was when I passed 10,000, so I’m a little sad to have missed the party. That said, 1 million is quite a number for a humble little blog that doesn’t discuss Lady Gaga or religion (very often).

So thank-you to everyone that has visited and contributed to all the various discussions over the years.

The good news, I have a couple of new articles that will hopefully make an appearance in the next few days so the drought is nearly over ūüôā But first, I have a new episode of Game of Thrones Season III to get through ūüôā

I’m Back !! Oracle Index Internals Seminar Scheduled in Europe For June. April 3, 2013

Posted by Richard Foote in Oracle Index Seminar, Richard's Musings.

It’s been quite a while but I’ve recently been asked to present my Indexing Seminar in Europe for Oracle University and at this stage, all the planets seem to be aligning themselves to make this a distinct possibility.

Seminar details are as follows:

Location: Bucharest, Romania

When: 17-18 June 2013

Cost: 2000 RON (approx. 450 EUR)

Enrolment: Follow this link

This will be a unique opportunity as I just don’t get the chance in my schedule to present this any more,¬†to learn some rather interesting and useful information on all things to do with Oracle indexes. Note there are currently no plans to schedule other events in the foreseeable future, this is it.

Hopefully you’ll get the opportunity to attend and I’ll get to meet you in beautiful Bucharest ūüôā

5 Year Anniversary (5 Years) December 20, 2012

Posted by Richard Foote in Richard's Musings.

It’s just occurred to me that I’ve just recently past the 5 year anniversary of when I started this humble little blog !!

My first real post on Invisible Indexes was written back on 11 December 2007. Some 256 posts later and I’m still here, posting occasionally on Oracle Indexes with as many David Bowie references as I can manage ūüôā

There have been roughly 923,000 page views in that time and more importantly some 3,000+ comments in total, some of them driving shall we say “interesting and lively” debates. The entry with the most comments is this one on how execution plans can suddenly when the statistics remain unchanged, although this one on rebuilding indexes every Sunday afternoon was up there as well.

The most views on any given day was back on March 13, 2010 with 3606 views, when this entry on block and tree dumps was particularly hammered. The most popular blog entry of all time however goes to this one on the change of behaviour of dbms_stats with 10g, with this one on the differences between an index rebuild, coalesce and shrink a very close second.

My all-time favourite blog entry however is this April Fool’s one on my retirement announcement and plans to work in the adult film industry. Some of the comments on this one are just classic ūüôā

A very sincere thank-you to all my loyal readers and to everyone who has contributed to this blog over the years, I hope you’ve learnt something new along the way. I certainly have !! With the Oracle 12c database due for release sometime in 2013, I’m sure there will be lots to write about for a while longer yet ūüôā

Pushing through the market square, so many mothers sighing, news had just come over we had 5 years left to cry in

Back At Oracle Corporation (The Return Of The Thin White Duke) November 30, 2011

Posted by Richard Foote in Richard's Musings.

I’ve been very quiet on the blogging front lately, so apologies for that.

One of the main reasons is that after a period of nearly 10 years, I’ve decided to take up a position back at Oracle Corporation as a “Principal Solutions Consultant” in sunny Canberra. So things have been rather hectic, finishing up in my previous job and starting up afresh at Oracle. Things have certainly changed a lot over this time, with new offices and a much larger workforce than worked in Canberra previously. Some things haven’t changed such as I’ve still got my old email address and the same employee number (2020)¬†as before. I’ve got that feeling of being really excited again at work which I’ve missed recently so I’m really looking forward to my many¬†new adventures to come at Oracle.

The good news is that I’ve been given the green light to continue on with my blogging activities so expect action on that front here again¬†soon. I’ll still be keeping it¬†technical (unless there’s a new David Bowie album or Pink Floyd Box-set to discuss of course) and I’ll still be talking mainly about indexes as there’s heaps that I’ll still¬†like to cover such as Secondary Indexes on IOTs¬†as promised previously, as well as looking at more “exotic” indexes such as those for Spatial, XML, Oracle Text etc. There are also a few “rumours” regarding not needing indexes with Exadata which might potentially become full-blown myths if I don’t do something about it ūüôā

I’ll also get back to answering the various questions that have been building up over the past few weeks.

So stay tuned !!

The Dark Side Of The Moon Immersion Box Set September 4, 2011

Posted by Richard Foote in Pink Floyd, Richard's Musings, The Dark Side of the Moon.

It’s Father’s Day here today in Australia and because I’ve naturally been a really really good Dad all year, my family have given me a real treat for my present¬†this year, the Immersion Box Set of the Pink Floyd classic, The Dark Side Of The Moon (although unfortunately, I have¬†to wait a couple of weeks¬†for it to get released until I can get my hands on it).

As the days of actually having a physical format for music (be it record or tape or CD or whatever) to hold and hug are fast disappearing in this age of digital downloads, Pink Floyd have decided to re-release their back catalogue in physical format one last time with some style.

All their albums are being re-released in new digitally remastered formats, but three of their very best albums (The Dark Side Of The Moon in late September, Wish You Were Here in November and The Wall in February 2012) get the special treatment with the release of Immersion Box Sets.

So what do you get in TDSOTM Immersion Box Set ?

The answer is heaps !!

In a very large box (naturally), you get:

Disc 1 , a CD containing a digitally remastered version of the album

Disc 2, a CD containing a previously unreleased live concert at Wembley dating back to 1974.

Disc 3, an audio DVD containing various 5.1 Surround Sound and Quadraphonic (as originally released in 1973) mixes of the album

Disc 4, a visual DVD containing various live performances, documentaries and all the original concert screen films (makes me want to go out and buy a circular TV !!)

Disc 5, a Blu-Ray containing both audio and video highlights of what I’ve listed already

Disc 6, a CD containing previously unreleased material, including demos and the various live sequences that didn’t quite make it onto the final album.

You also get a whole bunch of other goodies, including colour booklets, a photo book, Storm Thorgerson artwork and cards, a set of 9 coasters, a scarf (just in time for our Canberra summer), Pink Floyd marbles (of course) and replicas of various memorabilia.

I can’t wait !!

I’m almost pitying the neighbours already as I fully plan to sit in the middle of my surround sound system and play all this as it was intended.¬†REALLY REALLY LOUD !!

If you want more details or you’re interested in buying this as well, simply click on the picture of the album artwork above.

This will definitely make my Recommendations Page ūüôā

A Few Random Notes June 18, 2011

Just a few random notes.

Oracle Mix have the Oracle OpenWorld 2011 Suggest-A-Session again this year with lots of good presentations as always. Follow the link to vote for my Q & A session on Oracle Indexing.

Jonathan Lewis has an interesting quiz on Oracle Indexes in answer to a question from the OTN forums:

‚ÄúIf I delete 90% of the rows¬†from a table which has a few indexes, without rebuilding or coalescing indexes afterwards, will this improve the performance of index range scans ?‚ÄĚ

Check out his Night Quiz blog entry for an excellent discussion on how things might be better, worse, unchanged or possibly all three in answer to the question.

I’ve received¬†quite a number of emails and blog comments regarding errors in trying to access some of my older demos. There appears to be a problem with later versions of WordPress not supporting plain text files. I have on my to-do list the¬†task of converting these files to PDF format so they can be generally viewable again. I hope to complete this thrilling task in the¬†next week or so. Will keep you informed.

Finally, I had my paper on “10 Things You Possibly Don’t Know About Oracle Indexes” accepted for this years InSync11 Conference, to be held this year on 16-17 August 2011 at the Convention Centre in Sydney. As usual, there’s a great array of presenters including Tom Kyte, Connor McDonald, Chris Muir, Tim Hall, Graham Wood¬†and Marcelle Kratochvil to name but a very few. Follow the link for the Full 2 Day Programme. Looking forward to it already and the opportunity to catch up with a lot of folks.

For those of you wondering, my negotiations with Manchester United, Barcelona and South Cooma Over 45’s Second 11¬†are still ongoing ūüôā

The Best Goal Ever !! (Fearless) June 12, 2011

Posted by Richard Foote in Richard's Musings.

Australia (and Canberra specifically) had recently been suffering from two very long and difficult droughts.

One had been a severe lack of rain, which left dams at record low levels. After many years, this ended earlier in the year with rain aplenty and with local dams at long last back at 100% capacity.

The other drought however only just ended last week. That being for nearly three very long and difficult years, I had not managed to score a single goal for my local football team, the mighty Lanyon¬†United. Well at long long last, this drought was also finally broken last week with arguably the best goal in the history of the game (well OK, perhaps I’m exaggerating just a tiny bit with the quality of the goal).

Here it is !!

Time (Hanging On In Quiet Desperation) !! September 14, 2010

UPDATE: My first presentation at OpenWorld on Sunday “Session S318615: ‚ÄúIOUG Oracle Indexing Tips, Tricks and Traps” is now FULL. Hopefully you have already pre-registered although sometimes with these things, the presentation might be moved to a bigger room.

For those of you who may have been wondering why it’s been so quiet here lately, no, while driving home from work one dark evening, I haven’t been taken by aliens¬†on board¬†their mothership, to a¬†beautiful but mysterious¬†galaxy far far away, to be experimented on and mind probed into why earthling indexes in Oracle databases need to be rebuilt so infrequently …

I’ve just been really really busy !!!

The InSync10¬†Conference in Melbourne last month was excellent, a really good 2 days and it was nice to catch up with lots of my Oracle friends such as John Bushell, Tom Kyte, Connor McDonald, Mogens¬†Norgaard, Debra¬†Lilley, Kyle Hailey, Penny Cookson, Jeannie Dobney, Tony Jambu,¬†as well as¬†meeting lots of other nice people as well. My talk was well attended (considering the stiff competition) and seem to go well considering the nice feedback I’ve received.

However, the biggest thrill of all was catching up with Stanley the ACE vest again. You can just see the excitement on my face in this picture of me with Stanley !!

Since then it’s been non-stop. I’ve been on Oracle training courses, I’ve been finalising my presentations for OpenWorld, updating my seminar materials for the upcoming seminars in Europe next month, in heavy training trying to overcome various injuries so I can compete in the football final series (we managed to make the grand final again this year only to be beaten by Canberra FC 0-1), helping kids with their homework revision (I had forgotten just what fun maths and simultaneous equations can be !!), trying to learn and experiment¬†and pick up as much 11g release 2 knowledge as I possibly can at work ready for our upcoming upgrades, and on and on it goes.

So unfortunately, my poor little blog has been rather sad and neglected lately as a result.

Things don’t appear to be slowing down anytime soon with my packing nearly done for my trip to Oracle Openworld¬†nearly upon me !! I’m again really looking forward to catching up with lots of people in San Francisco, should be another excellent experience. Received an email recently from Oracle marketing to say that my first presentation on the Sunday is filling up fast, which is nice to know. My agenda is:

Session S318615: ‚ÄúIOUG: Oracle Indexing Tips Trick and Traps‚ÄĚ ‚Äď Sunday September 19, 12:30pm Moscone¬†West L2 Room 2005

Session S319069: ‚ÄúOracle Indexing New Features In Oracle11g¬†R1¬†and R2‚Ä≥ ‚Äď Monday September 20, 2:00pm Moscone South Room 303

‚ÄúUnconference: Oracle Indexing Q & A With Richard Foote‚ÄĚ Tuesday 21 September, 10:00am Hotel Parc 55 Mason Room

Hopefully, I’ll have the chance to catch up with a lot of you in the coming week at OpenWorld. ¬†To gurantee a place in the first two sessions, I would recommend booking ASAP via the Scheduler Builder facility.

A sad thing about going to Oracle OpenWorld this year¬†however is that I’ll miss my local rugby league team, the Canberra Raiders playing a home final against the Western Tigers. I’ve a feeling this could finally be our year and I’ll miss on most of the final series while in the US. Go the mighty Green Machine !! Hopefully, I’ll be back in time to watch them win the grand final.

Finally, just want to quickly mention the Michigan OakTable Symposium 2010 Conference that’s on this week. I would dearly love to go but my schedule made it impossible. However, it’s a fantastic conference with a truly quality list of speakers and if you have the chance to go, I would strongly recommend grabbing that chance.

Hoping to write a few blog posts in the coming days, to complete my little series on block dumps, to write a few things from OpenWorld, cover some of the nice little goodies from 11g that are index related and review the fantastic deluxe re-release of the classic David Bowie album, “Station to Station”.

But for now, it’s back to the packing and making sure I have enough undies for the trip to OpenWorld ūüôā

World Cup, Insync10 and Coming Index Block Dumps July 12, 2010

Posted by Richard Foote in InSync10, Richard's Musings, World Cup.

Well after a month of watching the World Cup during these long cold Canberra nights, my beloved Spain have finally, at long long last, after years and years of bitter disappointment and despair, have deservedly won the World Cup !! Iniesta, you legend, you will never have to buy a drink ever again, whenever or wherever you walk into any bar in Spain !!

Life now¬†just isn’t going to be quite the same again …

My dream now is for Australia to both host the World Cup in 2022 and to win it one day as well.

With Cadel Evans now leading the Tour de France, perhaps I have a few more weeks of sporting late nights ahead of me still …

For those of you in Australia, just a reminder that the InSync10 Conference¬†in Melbourne is fast approaching.¬†I’ll be both attending and presenting this year and will be joined by a host of great speakers including Tom Kyte, Mogens¬†Norgaard, Debra Lilley, Steven Feurestein, Connor McDonald, Kyle Hailey, Guy Harrison¬†and¬†Penny Cookson to name but a few. Should be a great event and I strongly¬†recommend making it to Melbourne if you can.

My session on “Indexing New Features in 11g R1 & R2” is in Room 106 on Tuesday, 17 August 10:00am-10:45am.

I’ll soon be posting a series on Index Block Dumps, discussing how to read and interpret them and how they can be incredible useful in learning not only how Oracle indexes actually work¬†and behave but also the internals to many core Oracle concepts such as row level locking, concurrency and read consistency.

But for tonight, a long night’s sleep finally awaits. Buenos noches …
