OUG Ireland 2016 – Summary

oug-ireland-2016

The day started at 05:00. I lay in the bath for 20 minutes in denial, wondering how I would manage to stay awake for the day. I’ve been ill for ages, so I felt like I was running on empty anyway. Once I had managed to drag myself out of the bath and get dressed, I picked up my laptop and took a taxi to the airport.

The taxi to the airport was smooth enough. I was already checked in and had no bags to drop off, so I went straight for the security and was greeted by the biggest queue I had ever seen at Birmingham airport. To all those people that laugh at me getting to the airport 2+ hours before a short flight like this I say, “Better to be safe than sorry!”

Loss Aversion and the Setting of DB_BLOCK_CHECKSUM

Within Accenture Enkitec Group, we have recently been discussing the Oracle db_block_checksum parameter and how difficult it is to get clients to set it to a safer setting.

Clients are always concerned about the performance impact of features like this. Several years ago, I met a lot of people who had—in response to some expensive advice with which I strongly disagreed—turned off redo logging with an underscore parameter. The performance they would get from doing this would set the expectation level in their mind, which would cause them to resist (strenuously!) any notion of switching this [now horribly expensive] logging back on. Of course, it makes you wish that it had never even been a parameter.

VirtualBox 5.0.16

VirtualBox 5.0.16 was released yesterday.

Downloads and changelog are in the usual places.

The installation went fine at work on Windows 7 and on Mac OS X (El Crapitan) at home.

HotSos Symposium and IOUG Collaborate 2016

I fly out on Sunday for HotSos and am looking forward to giving a joint keynote with Jeff Smith, as well as giving two brand new sessions on

Hotsos 2016

I’m going to Hotsos 2016 soon for the first time. I’ll speak about Middleware and the issues I see commonly everywhere. It took me quite some time to prepare for this trip: budget, visa, and, most importantly, presentation – required at least 120 hours of my time (which is a lot). In fact presentation is still work in progress and I hope to finish it just before March 8 when I’m presenting. I feel a bit nervous about my topic since the conference is all about Database Performance, the quality of presentations is always high and they are super technical, while I’m planning to have a light talk focused not on the Database mainly – just my rants on the things done wrong I usually see in the wild everywhere. It’s not something on the cutting edge, and some of my notes are so bloody old.

DBaaS RESTful API Cook Book

Having a GUI tool like Enterprise Manager Cloud Control to manage your entire data center is an imperative for most enterprises these days. But in the cloud paradigm, you must also have a uniform API that can be used to tailor the cloud to your business processes and economic models. That API is known as the REST API, and services based on that are known as RESTful services.

OUG Ireland 2016

oug-ireland-2016

Early tomorrow morning I will start my journey to Ireland for the OUG Ireland 2016 conference.

I’ve got back-to-back sessions in the afternoon on database consolidation and analytic functions. I was invited to a panel on the Friday also, but I had already booked my flights before that invite, so sadly I had to decline.

This year is going to be another day trip for me, with the flight costing a gigantic £27 on ChavAir. :)

See you there!

EM13c DBaaS, Part 1 On-Premise and the Test Master

With EM13c, DBaaS has never been easier.  No matter if you’re solution is on-premise, hybrid, (on-premise to the cloud and back) or all cloud, you’ll find that the ability to take on DevOps challenges and ease the demands on you as the DBA is viewed as the source of much of the contention.
