Announcement: Singapore Oracle Sessions

When I knew that the ACE Director, Bjoern Rost of Portrix Systems was coming to Singapore on his way to begin the OTN APAC tour, I suggested he stay at mine for a few days and sample all that Singapore has to offer.

Then a thought occurred to me. While he was here, why not setup an informal Oracle users meetup, much like the various ones at cities around the world like Sydney, Birmingham and London (to name but three I’m aware of). Morten Egan, my new colleague and Oak Table luminary had already suggested to me months ago that we should get something going in Singapore, so why not start now?

Well, in a matter of a few days, we’ve put together an agenda, a room, we will be having pizza and beer and other drinks and three hopefully useful sessions from experienced speakers. 

Here is the agenda (SingaporeOracleSessions.pdf) and a map (SOSMap.pdf) to help you get to the venue which is very handily placed near Bugis MRT. All that’s required to register is to email me at dougburns at Yahoo. There are currently 21 people registered but the room holds (believe it or not) 42, so spread the word!

Hopefully, it’s just the beginning ….

A Zone being a range of contiguous (8M) blocks. I […]

Metric Thresholds and the Power to Adapt

Metric thresholds have come a long way since I started working with OEM 10g.  I remember how frustrating it could be if an ETL load impacted the metric values that had to be set for a given IO or CPU load for a database when during business hours, a much lower value would be preferable.  […]

A World View

I’ve mentioned this before, but I thought I would show something visual… The majority of my readers come from the USA and India. Since they are in different time zones, it spreads the load throughout the day. When I wake up, India are dominant. In the afternoon the USA come online, by which time Russia have […]

Google Glass, Android Wear, and Apple Watch

I have both the Google Glass and Android Wear (Samsung Gear Live, Moto 360), and often times I wear them together.  People always come up with a question:  “How do you compare Google Glass and Android watches?”.  Let me address couple of the view points here.  I would like to talk about Apple Watch, but […]

phpBB 3.1 Ascraeus Released

Just a quick heads-up for those that use it, phpBB 3.1 Ascraeus as been released. It’s a feature release, so the upgrade is a bit messy. I did the “automatic” upgrade. There was so much manual work involved, I would recommend you take the approach of deleting the old files, replacing with the new ones, then […]
