- About this Webcast --
Join Anjo Kolk, Chief Oracle Technologist at Precise Software and
renowned Oracle performance author, for his views on Oracle
performance tuning. Anjo will discuss how conventional tuning
approaches rely too heavily on checking the buffer cache hit ratio.
Many DBAs do their best to get a 99% or better hit ratio but discover
that the performance of their database isn't really improving when
the hit ratio gets better. Anjo will discuss these points and others:
- If the hit ratio was tuned to 99% or better, why is end user
response time still bad?
- If tuning the hit ratio is not the answer to end-user response
time, what is?
- Why does a hit ratio do exactly the opposite of what you would
think?
- Logical I/Os -- The myths dispelled.
- How to calculate the cost of a logical I/O.
- How to use the response time model in Oracle to find performance
problems.
