This program was recorded on Wednesday, September 21, 2016, during Oracle OpenWorld in San Francisco. "During" is the operative word, since the podcast was actually recorded in my hotel room, several blocks from Moscone Center, where OOW16 was held. The topic was suggested by Oracle ACE and frequent OTN contributor Arturo Viveros, who, along with other panelists, was in town for the big Oracle event. Listen.

I’ve written notes in the past about the improvements 12c introduces for histograms – particularly the frequency and top-N histograms which can be generated “free of charge” while the basic “approximate NDV” scans are taking place to gather stats. Gathering histograms in 12c is much safer than it used to be in earlier versions of Oracle even in the case of the new hybrid histograms (which are still sampled on a very small sample and (more...)
I love technology- ALL TECHNOLOGY. This includes loving my Mac Air and loving my Microsoft Surface Pro 4. I’ve recently went back to a Mac when I joined Delphix, trimming down the power I had on my Surface Pro 4, knowing the content I was providing would be required to run on hardware with lesser resources.
With the release of Microsoft SQL Server 2016 on Linux, I (more...)
In the previous post I threw out a couple of options for addressing the requirement to transfer data from one table to another (“cut and paste” rather than just “copy”) without running into odd inconsistency errors. This triggered of a wonderful comment trail of alternatives based on how large the volume might be, how relaxed the concurrency requirements might be, and so on.
#DOAG2016, the largest Oracle Community gathering in Europe. Taking place in Nuremberg, at the Nuremberg Convention Center NCC, one of the more impressive places to hold such a conference, towering 4 stories high, with a big central atrium!!
It is a huge effort to get all of this together!
The Conference is the premier event for Oracle users in the UK (and beyond). This year has another cracker of an agenda: check it out.
The session (more...)
If you try the newest version 220.127.116.11 (or maybe earlier versions too) you see, that your managed server does not restart, when
- you have deployed your ADF application(s)
- you try to restart the managed server with ADF
- you use intentionally or not shared libraries in your weblogic-application.xml (see example below)
<?xml version = '1.0' encoding = 'UTF-8'?> <weblogic-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/weblogic-application http://www.bea.com/ns/weblogic/weblogic-application/1.0/weblogic-application. (more...)
The challenge of coding, is that you sometimes need to be aware of what can be impacted outside of your code to make it appear guilty.
I wrote a blog post a short time back on my first time scripting with Apple Script with a goal of automating my weekly status reports to my new manager of my tasks in OmniFocus. After seeing some cool stuff one of (more...)
If you fancy coming along to my session, it’s on Wednesday 11:30 – 12:20 and it’s called Put Your Feet Up & Have a REST. Take a Tour of JSON Support in the Oracle Database.
We might be celebrating my nephew’s birthday on the Saturday this (more...)
Many of the questions that appear on OTN are deceptively simple until you start thinking carefully about the implications; one such showed up a little while ago:
What i want to do is to delete rows from table where it matches condition upper(CATEGORY_DESCRIPTION) like ‘%BOOK%’.
At the same time i want these rows to be inserted into other table.
The first problem is this: how carefully does the requirement need to be stated before (more...)
VirtualBox 5.1.10 has been released.
I’ve only tried it on Windows 7 at work so far. I’ll try it out on Mac and Oracle Linux 6 hosts when I get home and put an update on the post.
VirtualBox 5.1.10 was first posted on November 22, 2016 at 1:17 pm.

I noticed an interesting security problem (exploit?) on Oracle Enterprise Manager Cloud Control 13cR2 (I tested on EM13cR1 and it also exists on there). When you create an Enterprise Manager administrator, you need to grant some special privileges to that administrator if you want them to access the performance pages, but it seems there’s an alternative way to access the performance pages without requiring extra privileges.
Let’s say I created a new administrator with (more...)
I had a great time at DOAG 2016. It’s one of the best run conferences I’ve been to! I did a quick cameo during the keynote to talk about performance in Oracle’s cloud. Nothing like being on stage with a guy wearing a tie. :) Thanks Andrew for inviting me to say a few words.
That was fun! Here’s a link to the paper I referenced:
Then I did (more...)
