Oracle Scratchpad

June 3, 2019

So long …

Filed under: Non-technical — Jonathan Lewis @ 2:09 pm BST Jun 3,2019

… and thanks for any Douglas Adams references.

I decided on Friday that after more than 31 years using the Oracle software and more than 37 years of being self-employed in the computer industry – not to mention a further 8 years being an enthusiastic amateur – the time had finally come for a change of pace.  As from 1st June 2019 I am retired.

I have a couple of long term commitments that I’ll still be doing a little work for over the next few months, and I wouldn’t be surprised if someone occasionally tempts me into doing a few days solving interesting problems.  I’ll still be answering questions on the Oracle Developer Community forum and (if the email gets through) on the Oracle-L listserver , and I’ll still be writing blog notes about Oracle and submitting abstracts to conferences for a few years. Who knows, I may even get round to writing another book – after all, I’ve already downloaded Oracle 19 so I’ll still be experimenting, investigating, and trying to break things Some people retire to do the Times crossword or Sudoku, my retirement pastime is going to be playing with Oracle.

But now I’ve got 3 musical instruments to re-learn, a garden to re-engineer, apple trees to train, and a lot of rowing [U.S. “crew”] time to catch up on so that I can get fit enough to get back to playing squash (which might be an interesting experience now that my eyesight has been fixed). And for relaxation I’ll be sitting in the garden watching the birds, drinking fine wine and reading a good book.

Update (6th June 2019)

Thanks for all the appreciative comments to know. It’s nice to have a record, both here and on the tweet, of the fact that I have made a difference for so many people.

  1. Jonathan, you have been an Oracle hero to many including myself. I still treasure a signed copy of your Oracle 8i book. I hope you enjoy ‘retirement’.

  3. I think it’s safe to say that everyone in Oracle community learned something from you. Most people learned from you more than what they learned from all other sources (including official Oracle documentation). But there’s still so much more we could learn from you, so I’m hoping this really isn’t a goodbye, and you’d still occasionally share your knowledge and enthusiasm with us, whether it’s in the form of books, articles or conferences talks.

    In any case, enjoy your retirement. I’m looking forward to your next tweets — whether they are about database internals or sourdough :)

  7. This is the most unconvincing retirement I’ve ever heard. :)

    So you are retired, but you are still going to:

    – Answer questions.
    – Write posts.
    – Possibly write a book.
    – Present at conferences.
    – Possibly work if someone offers you something interesting.

    Enjoy your “retirement”. :)

    Cheers

  8. Sour dough seems to be the common theme that robs the Oracle community of knowledge :-)

  9. Echoing all the previous comments. Any attempt to ratify your contribution to the oracle community is superfluous. The body of work produced is so vast I know I’ll be learning from you for years to come. All the best for the future.

  11. Thanks for all you’ve done for the community, Jonathan. I hope you enjoy “retirement” as much as you’ve enjoyed probing the nooks and crannies of Oracle Database.

  16. Jonathan, I am really happy to hear that besides other activities, you will continue to be Oracle-active and we could still expect your awesome
    posts, answers, and, … yes :) … maybe books coming.
    I wish you all the best in all your other activities and I can only hope that maybe some time in the future we will have the opportunity to meet again,
    as we did back in 2015 … now that we are kind of “fellows” … retired people that just cannot stop Oracle-ing :)
    Thanks a lot for all the deep knowledge that you have shared with us along so many years
    and thanks in advance for all your future gifts for us all :)
    Remain always with us, the Oracle world would be much more poor without knowledge like yours :)

  21. Enjoy your retirement and thanks for all of your contributions! Your book on cost based Oracle fundamentals was real eye-opened for me back when it was published! Also I met you briefly in Finland when you were delivering a seminar maybe 2004 or 2005 and as a junior DBA back then it was nice you took time to answer any questions I had. :)

  24. I would be devastated to see you go, but I’m also leaving the Oracle world. I want to thank you for all you’ve done; I’ve learned more from your books, blogs and presentations than any other source. I don’t think I ever missed one of your conference presentations, and was honored beyond belief when you attended one of mine on performance tuning.
    All the happiness in the world in your retirement!

  25. Hello Jonathan :-),

    Yesterday evening I had known you wrote total two notes from “Feedspot today”. When I’ve heard you were going to be retired I know sooner or later this day will come. Enjoy for your retired life, your intention after retiring is really awesome.

    Thank you so much for a ton of contributing on oracle community and oracle-l. Every time I submit a thread on ODC you’ve minutely and seriously replied to me and in particular I always learn something new from you.

    FYI I’m looking forward to publishing your third Oracle new book.

    Best Regards

  26. Hi Jonathan,

    Probably, the most memorably and fan-boy moments for Amardeep and I were meeting you in-person in Hyderabad and spending the evening together doing the sight-seeing. Still those memories are as fresh in mind as it happened yesterday only and we shall cherish those moments for forever. Thank you so much for all the questions that you have answered, for all the knowledge that you have shared and above all, showing us how to be so much knowledgeable and yet, so humble, approachable and helpful to all those who need to be corrected, guided and mentored. I certainly wish that your “retirement” plans will work out just the way you have mentioned and it will be so good to read another book(having it autographed will be even better but one can’t be too hopeful always, isn’t it) reading the blog posts and above all, having you around in the Oracle community.

    Thank you once again and enjoy your retirement.

    King regards,
    Aman….

    • Thank you Jonathan for everything. Your comments on Oracle-L, OTN forums & books; everything has been a great source of information for the community. We are gonna miss you. As you mentioned, hope you will continue to write. Now even more as there will be no work pressure ;)

      Wishing you the best. Enjoy your retirement !

    good to know that you will continue to write here (and on ODC and Oracle-L): beeing a great admirer of your style I would miss your writing almost as much as your technical knowledge. Enjoy your retirement.

  28. Jonathan,

    I join the chorus of praise and thanks for all your contributions and for the peerless example you have set. Having enjoyed your company a few times, what I am most grateful for is not what you have presented, posted or published but simply who you are.

    Since you’re not abandoning the Oracle community completely, we’ll “expect you when we see you”…

    May the future bring every possible delight to you and all you hold dear.

    Kindest regards,
    Stew

  29. Times, they are changin’ …

    It feels like yesterday when I started reading columns from you and other people regarding Oracle (for example Tom Kyte, who also left the scene).

    In reality we’re now talking about almost 20 years. Now you too are going in retirement and so are other people around me, which I’ve worked with for a couple of years. Can’t say I like that change, but that is life. There’s a new generation taking over now, which I hope will learn from the experience of their predecessors – I’m doing the best I can, using the vast knowledge that you and others offer in your blogs and other sources.

    I still remember one talk in Vienna you did a couple of years ago (but can’t say what year or which session it was, so much for my memory) and your example “the DB is slow when it rains”. ;-) Good times.

    What I really want to say: Enjoy your retirement but keep “working”, whether it’s a new verison of Oracle DBMS or any other topic that keeps you interested.
    My hope is that I’ll see new and interesting entries in your blog until it’s my time to retire, selfish as I am. ;-)

  30. i would say YOUR retirement is only possible if you find a person that can replace 100% of your articles / blogs / posts / comments the next 5 years :-)
    Just joking, Thanks for all. Best wishes from Munich. If you ever want to taste a real beer:-), i would spend one, mayby two (but not in the small glasses you use …. )

    • I wrote two books, one was loosely about Oracle, but I don’t find the effort worth while. I am writing articles instead, whatever I find interesting. Writing a book is a hard work, which takes slightly less than a year, and financial rewards are not particularly good. Speaking of articles, I am writing a blog entry about Oracle 19c HS (Heterogeneous Services) connecting to SQL Server on Linux. It will satisfy my inner feeling of being a good community member, but without the huge effort needed to complete a book. Anyone who has ever written a book, like Jonatha, Dom Brooks or Jared Still will tell you the same thing.

  46. About 5 years ago we had a brief chat at a UKOUG SIG event in Reading. You predicted then that you’d be out of work in….spookily…about 5 years. At the time you thought it would be NoSQL databases that caused the demise of your Oracle consultancy work. Who would have known it was squash instead! Thanks for all the hard work you’ve put into supporting the Oracle community. I learned enough about the Optimizer from your CBO book to carve out a career in Oracle application tuning, and for that I’ll be forever grateful. Enjoy rowing (really!?).

  48. All the best, my friend :-) I still remember when we met first time in 2002 in Steve Adams’ house and you some day later delivered your “when shit hits the fan”-presentation. But I don’t know if you and the junta accepted me as an OakTable member because of my two whisky bottles (one was an Ardbeg, 1975 if I remember) or my solution to your question “how can you prove how Oracle internally finds the key in the index leaf block”. But Mogens forwarded your comment to my solution that my investigation skills were a little bit unusual but brilliant. Thanks for that, the fish and everything. /Jocke

  52. I still remember reading the first article of yours in the 90’s when partitioning was released (8.0), while everyone cheered it, your article pointed out how the partition view (the only “partitioning” available until then) was superior in certain query performance with an example. I have been a follower ever since. I still have a copy of Practical Oracle 8i book of yours, which I consider is the best Oracle book that has some useful insights still valid even today.
    Thanks for all your contribution over the years, I learned a lot from your articles. I am glad you aren’t completely giving up, and would continue contributing online.

    Wishing you the best!

  54. Jonathan,

    Honestly, I’ve been pretty heads down busy lately, not attending many conferences or reading many blogs, but I saw your ‘in case you missed it’ Tweet, which lead me here.

    Congratulations on your retirement, or, as someone else said, ‘retirement’…. :-)

    It’s been a pleasure knowing you and learning so much from you over the years! I hope to see you at a conference in the future!

  56. I still remember when I started learning Oracle in earnest and I had two books constantly with me – the “Blue Book” (your “Practical Oracle 8i”) and the “Red Book” (Tom’s “Expert one-on-one Oracle”), whose cover images I still remember vividly nowadays (even if a few drops of water have passed under the bridge), and that bring back happy memories of the good old times.
    And I still remember your kindness in accepting to read my paper about the Histograms, even if you were very busy … not to mention all other interactions we had during those early, exciting years.
    So many thanks for everything, for all the fish and the pudding as well :)
