Impressions from #ukoug_tech14

ACC Liverpool

The Oracle circus went to Liverpool this year for the annual conference of the UK Oracle User Group and it was a fantastic event there! Top speakers and a very knowledgeable audience too, I was really impressed by the quality we have experienced. Together with my friends and colleagues Iloon and Joel, I was waving the flag for Oracle University again – and it was really fun to do so :-)

One little obstacle was that I actually did many presentations and roundtables. So less time for me to listen to the high quality talks of the other speakers…

Joel and I hosted three roundtables:

About Exadata, where we had amongst others Dan Norris (Member of the Platform Integration MAA Team, Oracle) and Jason Arneil (Solutions Architect, e-DBA) contributing

Exadata Roundtable

About Grid Infrastructure & RAC, where Ian Cookson (Product Manager  Clusterware, Oracle) took many questions from the audience. We could have had Markus Michalewicz also if I only would have told him the day before during the party night – I’m still embarrassed about that.

About Data Guard, where Larry Carpenter (Master product Manager Data Guard and Maximum Availability Architecture, Oracle) took all the questions as usual. AND he hit me for the article about the Active Data Guard underscore parameter, so I think I will remove it…

Iloon delivered her presentation about Apex for DBA Audience, which was very much appreciated and attracted a big crowd again, same as in Nürnberg before.

Joel had two talks on Sunday already: Managing Sequences in a RAC Environment (This is actually a more complex topic than you may think!) and Oracle Automatic Parallel Execution (Obviously complex stuff)

I did two presentations as well: The Data Guard Broker – Why it is recommended and Data Guard 12c New Features in Action

Both times, the UKOUG was so kind to give me very large rooms, and I can say that they haven’t looked empty although I faced tough competition by other interesting talks. This is from the first presentation:

A big THANK YOU goes out to all the friendly people of UKOUG who made this possible and maintained the great event Tech14 was! And also to the bright bunch of Oracle colleagues and Oracle techies (speakers and attendees included) that gave me good company there: You guys are the best! Looking forward to see you at the next conference :-)

#DOAG2014 bits of info for DBAs

Just wanted to share some pieces of information from the recent DOAG annual conference that you may find interesting.

From Mike Dietrich’s presentation about Database Upgrade:

Mike Dietrich

Database Replay is extremely useful to predict after-upgrade performance on a test system,

especially we can record the production load on 10g even.

From Carsten Czarski’s talk about XML DB:

Carsten Czarski

With 12c, XML DB is mandatory and it provides an easy way to upload BLOBs via ftp into the database.

From Ulrike Schwinn’s talk about the Resource Manager I took away that

The resource manager becomes more and more popular and important, especially for Multitenant

- something Hans Forbrich reinforced later on.

Particularly I liked way she presented later on about ADO: Very many live demonstrations – that’s how I try to do my own presentations also :-)

Ulrike Schwinn

Frank Schneede did a great job debunking Exadata myths. For example,

You don’t need to have all cores enabled with Exadata X4 in order to save license cost. That’s called Capacity on Demand.

Frank Schneede

If I should name one presentation that was most useful for me, it’ll be probably Frank’s.

Markus Michalewicz delivered an excellent talk as expected about RAC cache fusion:

Markus Michalewicz

Two important messages:

RAC scales well (far) beyond three nodes because there are never more than three nodes involved for cache fusion intercommunication.

And Multitenant and RAC are a perfect fit.

One Data Guard snippet out of Larry Carpenter’s talk about Global Data Services (GDS):

GDS makes it possible to automate the failover of the Real-Time Query service to the primary in case the physical standby has an outage.

Larry Carpenter

Hans Forbrich talked about Multitenant. He showed great presentation skills and although I knew the technical details before, the way he highlighted certain aspects was still very helpful for me.

Hans Forbrich

One key message was that

Multitenant is here to stay.

DBAs should learn about it and become familiar with it as soon as possible,

because sooner than later it will have to be administered in production!
