Find Oracle tables with high DML update insert delete

Oracle Database Tips by Burleson Consulting

May 17, 2016

Question: What do I do to find all Oracle tables that have high activity?  I want to see all tables that experience high DML activity, high volumes of insert, update and delete activity.  What is the script to display this?

Answer:  The Oracle diagnostic pack table dba_hist_seg_stat has information on high activity tables in Oracle.  This query against the dba_hist tables will display all Oracle tables with high activity:

SELECT seg.begin_interval_time  
      ,seg.end_interval_time  
      ,o.object_type  
      ,o.object_name  
      ,o.subobject_name  
      ,seg.db_block_changes_delta  
FROM  (  
SELECT * FROM (  
SELECT seg.snap_id  
      ,seg.dataobj#  
      ,ss.begin_interval_time  
      ,ss.end_interval_time  
      ,seg.db_block_changes_delta  
FROM  dba_hist_seg_stat seg  
JOIN  dba_hist_snapshot ss  
  ON  seg.snap_id = ss.snap_id  
WHERE  ss.begin_interval_time >= TRUNC(SYSDATE)  
AND    ss.end_interval_time <= TRUNC(SYSDATE)+INTERVAL'4'HOUR  
ORDER BY seg.db_block_changes_delta DESC  
      )  
WHERE  rownum <=15  
      ) seg  
JOIN  dba_objects o  
  ON  seg.dataobj# = o.data_object_id  
ORDER BY db_block_changes_delta;
