EXPLAIN and get some statistics on your SQL
- Haven't you ever thought there should be an easier way to do the EXPLAIN PLAN and TKPROF statistics than to edit your queries to add the commands (like EXPLAIN PLAN SET...), or to have to find or write a script that automates this? It should be an automatic part of SQL*Plus. Well, as of SQL*Plus 3.3 it is!! The command is called 'SET AUTOTRACE ON'!

- This is possibly one of the most useful tuning scripts available. The V$SYSTEM_EVENT dynamic performance view is the highest-level view of the "Session Wait Interface". Information in this view is cumulative since the database instance was started, and one can get a very good idea of what types of contention a database instance is (or is not) experiencing by monitoring this view.
