Oracle Scratchpad

Public Appearances

1st July 2015 Reading, UK: I’ll be presenting at the DBMS/RAC SIG of the UKOUG. The topic will be “Why Exadata needs In-memory DB”. I’ll be covering a critical performance problem with Exadata systems that starts to show itself with large complex queries, and explain how this makes the (licensed) optimisation strategy of “Vector Transformation” a necessity rather than a luxury.
7th July 2015 Birmingham, UK: I’ll be presenting at Oracle Midlands (see latest event here) on the topics of “Creating test data to model production” and “Five hints for optimising SQL”.
6th Aug 2015 London, UK: Provisional date for the next session of ClubOracle with e-DBA, beer, pizza and technical chat.
9th – 10th Sep 2015 Zurich, Switzerland: Christian Antognini is chairing his annual event on Oracle Performance and has asked me to deliver a couple of presentations. I’ll be speaking on  “Calculating Join Cardinality” and “Understanding Parallel Execution Plans”. Full speaker list and agenda at this URL.
5th – 9th Oct 2015 Johannesburg, South Africa: Provisional: Oracle University is organising an Expert Summit event, and has asked me to be one of the speakers.
25th – 29th Oct 2015 San Francisco, USA: I’ve put in a couple of abstracts for OpenWorld, but it’s fairly safe to assume I’ll show up even if I don’t get a speaking slot. My topics are: “Designing Tests”, “Core principles of trouble-shooting”, and “Reading parallel execution plans”
17th – 19th Nov 2015 Nuremberg, Germany: I’ve put a few abstracts in for the DOAG annual conference – the same three that I’ve submitted for OpenWorld and the “Five Hints” presentation I’m doing in Birmingam for Oracle Midlands.
7th – 9th Dec 2015 Birmingham: UKOUG Tech Conference 2015. I’ve put in an abstract on optimising by not doing the work you don’t need to do; and I’ve also proposed a couple of panel session on the Cost Based Optimizer, one for beginners and one for advanced users. If the panel proposals are accepted I’ll put out a call for a few questions to prime the sessions.
1st – 5th Feb 2016 London, UK Provisional: Oracle University is organising an Expert Summit event, and has asked me to be one of the speakers.
