Use when you are about to write or edit a comment in PL/SQL you are changing, or in a .sql deliverable headed for the database. One line, one fixed shape, and anything longer goes where it belongs instead. It fires on the act of commenting rather than on a request - catching yourself opening a second comment line above one statement is the trigger.
Use when a query, report or PL/SQL unit is slow, before adding an index or a hint, or when someone says "cham", "toi uu truy van", "optimize this query", "why is this report slow", "full table scan". Measures with the optimizer's own plan and statistics, changes one thing at a time, and proves the gain with the same measurement - license-safe, no AWR/ASH or Tuning Pack.
