Where the real technical talks are at OOW

What are the real technical talks at OOW amid all the marketing fluff? I don’t know all of them but I can vouch for the following

 

Openworld day minus 3

Its day minus 3, or day +1 depending on your point of view at Openworld 2014.

I’m here a few days early for the Ace Director briefings, where a selection of product managers provide an insight into what is coming in the Oracle world, either at Openworld or in the coming year.

I must admit, I arrived to the briefings somewhat sceptical because a couple of years ago, when I was last at the briefings, the managers seemed very hesitant to share anything with us, generally waving us off with “you’ll need to wait until the conference”, which of course defeats the entire purpose.

Oracle OpenWorld 2014 : The Journey Begins

I did my normal last minute packing last night. After a quick panic this morning, I was off in the taxi I for the airport.

I find it amazing how sense goes out of the window at airports. There was a big sign saying “Put empty trays on rollers”, so people were either leaving them or stacking them up. Either way, they were getting in the way. WTF? RTMF!

The first flight to Frankfurt was fine. While waiting to board I was staring at the guy in front thinking, “I’m sure I could do his fade better than that!” I might have to start hairdresser-base.com… :)

Is X a Big Data Product?

class="l-submain">
class="l-submain-h g-html i-cf">

Virtually everyone in data space today claims that they are a Big Data vendor and that their products are Big Data products. Of course — if you are not in Big Data then you are legacy. So how do you know whether a product is a Big Data product?

While there might not be fully objective criteria (and mainly because Big Data definition is still in the air and people interpret it as they see fit for their purpose), I think I can provide one good suggestion on how to determine when a certain product is NOT a Big Data product. Of course, it will depend on the definition of Big Data that you believe in. /> id="more-68979">

New 12c Default: Controlfile Autobackup On – But only for Multitenant

This a a little discovery from my present Oracle Database 12c New Features course in Copenhagen: The default setting for Controlfile Autobackup has changed to ON – but only for Multitenant, apparently:

Oracle Open World schedule

Here is my schedule of presentations at Open World this coming week.

I most excited about my talk on Sunday. The Phoenix Project is a awesome book everyone should read, DevOps is the rising star of IT and this talk will empower DBAs to take their careers to the next level with data virtualization – virtualize, govern and deliver data efficiently boosting your companies efficiencies and bottom line much greater than any other change one could make as a DBA.

Lock Time

Here’s a little detail I was forced to re-learn yesterday; it’s one of those things where it’s easy to say “yes, obviously” AFTER you’ve had it explained so I’m going to start by posing it as a question. Here are two samples of PL/SQL that using locking to handle a simple synchronisation mechanism; one uses a table as an object that can be locked, the other uses Oracle’s dbms_lock package. I’ve posted the code for each fragment, and a sample of what you see in v$lock if two sessions execute the code one after the other:

Table locking – the second session to run this code will wait for the first session to commit or rollback:

#Oracle Certification: Always go for the most recent one!

It is quite often that I encounter attendees in my Oracle University courses that strive to become OCP or sometimes even OCM, asking me whether they should better go for an older versions certificate before they take on the most recent. The reasoning behind those questions is mostly that it may be easier to do it with the older version. My advise is then always: Go for the most recent version! No Oracle Certification exam is easy, but the older versions certificate is already outdated. The now most recent one will become outdated also sooner as you may think :-)
