In Oracle Database 10g, only one query optimizer is supported: the Cost-Based Optimizer (CBO). Oracle's legacy optimizer, the Rule-Based Optimizer (RBO), is no longer supported. While the majority of applications running on Oracle today use the CBO, some applications continue to use the RBO. This paper describes the steps in migrated an application from the RBO to the CBO. The purpose of this paper is to describe how to migrate an existing application from the RBO to the CBO, a necessary pre-cursor for migrating RBO-based application to Oracle Database 10g.
