Ask Jonathan

Oracle Scene, the magazine of the UK Oracle User Group is piloting a new regular feature called Ask Jonathan,  a chance to get an answer to any question you may have about how the Oracle database engine works.

I’m aiming to answer two or three questions per issue over the course of the year, using a format similar to the one Tom Kyte used in Oracle Magazine:  so if you have a question about the mechanisms, strategies, or mathematics of how Oracle does its thing then attach it as a comment to this posting.

Ideally the questions will have to be quite short (no 20MB trace files, massive schema definitions, or convoluted and exotic setup requirements or it will be too long), and I’ll aim to write something like half a page of in response.  I may summarise the question, or pick out the most interesting feature if it’s a bit too long to publish and answer in its entirety.
