OTN APAC tour stop 3 – Tokyo, Japan

I woke up on Tuesday Morning with a bit of shock on confusion. Where was I? Did I oversleep? What day is it? Do I have to be at the airport and fly somewhere again? When you travel to a … Continue reading

Will the REAL Snap Clone functionality please stand up?

Every so often our competitors like to spread false information about our solutions so as to gain unfair advantage. I wanted to address this for the Enterprise Manager Snap Clone functionality, so this blog post describes the Snap Clone solution as it currently stands (November 2014). Let’s start by introducing…

OTN APAC 2014 : Tokyo to Beijing

Not much sleep last night. When I know I’ve got an early start I don’t sleep well because I’m worrying about waking up late. At 04:00 I started getting everything ready to leave.

Parallel Fun

As I write, there’s an ongoing thread on Oracle-L that started with the (paraphrased) question: “I’ve got this query that returns 7 million rows; when I change it to ‘select count(*)’ it returns in 4 seconds but when we display the full result set on screen it takes hours, and every second or two the screen pauses; how […]

Quick Links to Helpful Literature on Oracle Database In-Memory Column Store.

I’m surprised to find that Google is not cleanly ranking the helpful set of blog posts by Oracle’s Maria Colgan on the Oracle Database 12c In-Memory Column Store feature so I thought I’d put together this convenient set of links. Google search seems to only return a few of them in random order. Over time […]

OTN APAC 2014 : Tokyo – Day 1

Day 1 of the Tokyo event started with a taxi ride over to the conference venue. The traffic was not as bad as I expected, based on the stuff you see on TV. Does that mean TV has been lying to me all this time? Who’da thunk it? The event has 1 (mostly) English speaking […]

OLTP Compression, Drop Column, Partition Exchange

With Basic Compression, you cannot drop a column. But with Basic Compression, you can set as unused. With OLTP Compression, on the face of it, you can drop a column. But this is a lie/misdirection. In reality, the dropped column is just renamed. We see the column is not dropped but hidden: Note 1. The […]
