“SQL plan management is a preventative mechanism that enables the optimizer to automatically manage execution plans, ensuring that the database uses only known or verified plans.”

SPM has three main components:
• Plan Capture: OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES = TRUE (Automatic Initial Plan Capture), OPTIMIZER_USE_SQL_PLAN_BASELINE=TRUE
• Plan Selection
• Plan Verification/Evolution
