Access Path Scientific Analysis Part III
Now that we have an understanding of how we can influence access paths using hints and session parameter changes, let’s continue our discussion by reviewing the various types of indexes as well as indexing strategies that affect Oracle access path selection. We’ll complete this series next week when we use all of the information we have learned to perform our own scientific analysis on Oracle optimization.

We continue to analyze the affects that initialization parameters, statistics and hints have on SQL statement access paths. In this blog, we'll take a look at the hints we will be using to influence the optimizer to select an access path that is different from the one it would normally choose. We'll also review a few of the tools that we will be using to monitor and compare SQL statement access paths and performance for our upcoming tests.

We are breaking in to our regularly scheduled blog with the following emergency message: “Are you ready for the impact that the 2007 Daylight Saving Time Changes will have on your Oracle Ecosystems?” I think that after reading this blog, you’ll agree that much work needs to be done to ensure that our systems are able to handle the new Daylight Saving Time dates for 2007.
