Dynamic Statement Cache optimization with Click4DB

31 January 2018

Optimizing the Dynamic statement cache is like other DBMS management tasks : it is not complicated but it requires a series of steps that are time consuming :

  1. Show cache usage repartition by application
  2. Show cache usage repartition by programs
  3. For each candidate program :
    • Analyze the DSC to avoid statement with LIKE
    • Analyze the DSC to avoid statement using INDEX ON EXPRESSION
  4. Show a repartition that simulates the usage after implementation
  5. Show the CPU impact of the CONCENTRATE option on a specific program
