Step1: At first we need to identified the high load SQLs or
top SQLs that are responsible for performance problem or in
another word the sql that consume application workload and
system resources. We can easily identify them by reviewing
past SQL execution history available in the system.
Step 2: Now generate execution plan of those high load sql

execution plans for poorly performing SQL statements. While
taking corrective actions there is many considerations.
