Troubleshooting

If it’s a long night, and you’ve got nothing better to do waiting for the new year, then here’s some reading to keep you entertained. A collation of Tanel Poder’s trouble-shooting blog postings, dating from June 2007 to September 2013:

Public Speaking Tip 2 : Rehearse!

I can almost hear the chorus of, “Well durr!”, but stick with me…

Do you remember the kids at school that always said stuff like, “I’ve done no revision at all for these exams!”, when you knew full well they had been slaving away for weeks to prepare. Speak about rehearsing for a presentation at a conference and those kids all come out of the woodwork, but in the guise of Oracle geeks… :) Now I’m not calling these people liars, but rehearsal means very different things to different people.

For me, rehearsing involves the following to a greater or lesser degree:

“Twas four nights after Christmas” and Other Reasons Not to Eat McDonalds at 11PM

I’ve been working a good number of hours this December between project/clients for Enkitec and co-author work on the EM CLI book with Seth Miller and Ray Smith, plus my additional responsibilities as the Training Days Conference Director for RMOUG’s big conference coming up in 6 weeks.

Public Speaking Tip 1 : Do some public speaking!

A number of people have asked me how they can improve their public speaking. I don’t consider myself an expert, but I thought I’d share my thoughts over a series of posts. Why a series? Because I figured if I tried to write an all encompassing post on the subject it would become long and boring, so small sound-bites it is! :)

So the first suggestion I would make about improving your public speaking, is to actually do some public speaking. There’s a pretty simple rule in life, you tend to get good at things you do regularly. I would suggest that very few people in life can stand up in front of an audience for the first time and feel the audience is about to witness greatness. No matter how bad you are at presenting, after you’ve done 20, you will be better than you were at the start. After 40 you will be better than you were at 20…

Oracle Database 12c : Some Backup and Recovery Stuff

In a previous post, I had already listed an article on backup and recovery when using the Oracle 12c multitentant option.

In that article I made reference to a restriction when using flashback database against a CDB with a PDB that has had a point in time recovery. I finally got my head round this and posted a note about it here.

Dreaming of Google Searches (La La La Human Steps)

You know you’re a geek when you are dreaming of a conversation with someone, reach for your tablet to search for the answer to something and can’t find it. Due to your frustration in the dream, you wake up in real life, reach for your tablet and continue to search for the thing you couldn’t find in your dream!

That is exactly what happened to me this morning. In my dream I was recounting watching The Word as a kid and seeing Louise Lecavalier from La La La Human Steps. I was totally blown away! This was before the days of YouTube, so I had never seen anything like it before. I can’t find that performance on YouTube, but if you are interested, this was what the “dream conversation” was about.

Articles on Oracle Database 12c Multitenant Option

From a technology perspective, the Multitenant option is really cool, but it can be rather difficult to get to grips with some aspects of it. Everything is so intertwined and every feature in 12c somehow links back to the Multitentant option. As I’ve been working my way through the features the same pattern keeps repeating.

  • Write an article on a feature X.
  • Put it live.
  • Move on to looking at feature Y.
  • Notice something about feature Y that affects the article I’ve written about feature X.
  • Go back and revise the article on feature X.
  • Rinse and repeat.

This pattern has made me rather reluctant to post anything on the blog about new articles, because although I don’t release articles until I think they are finished, all these Multitenant articles feel very much like a work-in-progress. I fully expect to step back and revise/rewrite all of them as I figure more out about this stuff.

November/December Highlights

In the Oracle technical universe, it seems that the end of the calendar year is always eventful. First there’s OpenWorld: obviously significant for official announcements and insight into Oracle’s strategy. It’s also the week when many top engineers around the world meet up in San Francisco to catch up over beers – justifying hotel and flight expenses by preparing technical presentations of their most interesting and recent problems or projects. UKOUG and DOAG happen shortly after OpenWorld with a similar (but more European) impact – and December seems to mingle the domino effect of tweets and blog posts inspired by the conference social activity with holiday anticipation at work.

I avoided any conference trips this year but I still noticed the usual surge in interesting twitter and blog activity. It seems worthwhile to record a few highlights of the past two months as the year wraps up.

The worst enemy of companies today is thinking that they have the best processes that exist, that their IT organizations are using the latest and greatest technology and nothing better exists in the field. This mentality will be the undermining of many companies.
