As with Oracle databases, the DB2 database also uses an optimizer to analyze your SQL and generate the execution plan that it considers optimal (Access plans). The DB2 optimizer is actually a collection of standard Rules, and in general we just tell DB2 what to retrieve, not how to retrieve it. So what does the DB2 optimizer do to determine the optimal access pa

There are two ways to optimize Oracle's optimizer: Rule-based optimization method: rule-based optimization (RBO) Optimization method based on cost or statistic information (cost-based OPTIMIZATION:CBO) Rbo: When the optimizer analyzes SQL statements, it follows some rules that are predetermined within Oracle. For example, we usually go to the index when a column in a WHERE clause has an index. CBO appro
