Tom Kyte – How do you know what you know…

Tuesday Morning Keynote….. Tom Kyte

there have been 14 production releases of the database since I have been at Oracle. When a question comes up I have to think of the answer and think of what version the answer is correct for.

New ideas almost always come from those uncommitted to the status quo – from outsiders

educated incapacity – a barrier to creative ideas can be experience

assumptions – incorrect assumptions are barriers to creativity
                   – incorrect assumptions laed down the wrong roads

things like group by sorts the data. This assumption is wrong. order by sorts the data, group by sorts it by hash values. Emperical evidence is not always the correct view.

judgements – we tried that once…. it never worked….. the will never buy that

An exercise was done yesterday comparing a DBA with scripts against someone who is trained with the tools. The result was that the DBA with scripts could detect the problem quicker but could not fix the problem. The DBA with the tools was able to find the problem in a similar amount of time but the tool fixed the problem quicker.The focus for the tools that are being developed are to replace the mindane tasks, not to automate the function of the DBA.

Interesting comment. What I am good at today didn’t exist when I was 12 years old. It is important to remember that everything is transient. It is important to know the how and why and not the technology. The data is the important part that lasts, the process, application, and technology are what changes.
