Display various statistics for the amount of used database space. See also Determining Space Information (Oracle).

·        The Database System Check (Transactions DB16 and DB17): Configure and check important database parameters to be able to recognize critical database situations in time.

·        Update Statistics(Transactions DB20 and DB21): Configure the cost-based optimizer, and check and update optimizer statistics
