Setting the HEAT_MAP initialization parameter to ON causes the database to track read and write access of all segments, as well as modification of database blocks, due to DMLs and DDLs. The activities are not tracked for objects in SYSTEM and SYSAUX tablespaces.
Use this initialization parameter to enable or disable both the Heat Map and Automatic Data Optimization (ADO) features.
