To find the top SQL statements that have caused most block buffer reads:

Select buffer_gets, sql_text
    from v$sqlarea
    where buffer_gets > 10000
    order by buffer_gets desc;
    
    
To find the most frequently executed SQL:

round(s.allocated_memory_size/1024/1024/1024,2) as "Alloc Mem (GB)",

from

where
s.connection_id = c.connection_id and c.connection_status != 'IDLE'
