I've been tuning Oracle queries has more than two decades now. The CBO(Cost Based Optimizer) got the most job done. And most of the time we have to see things like: Normalization and Denormalization, Cardinality Ratio, Index Cluster Factor, etc. And as always has been true: 95% of Oracle performance is upon the design of the application.

Hello. The optimizer (CBO) works very poorly. For its successful work it is necessary to collect statistics constantly for tables, this can't always be done quickly. Therefore, if you have tables in which the number of records varies greatly in short time, the optimizer may build incorrect query plans. In this case, you must configure each query with hints to select the correct plan.
