    Is there any way I can find out if a table has a very high insert, update, delete activity?

    Using the Log Miner will be the best option, if you are using 8i. See there us a link on how to go about Using LogMiner

    Check for the i/o activity on that particular datafile(tablespace) where that table belongs to, If its not too big table and on across many filesystems.

    Simplest way to find the high deletes ,insert,update on a table is through Monitoring.

    analyze table table_name com....

    Alter table tablename monitor;

    select * from DBA_TAB_MODICATIONS will tell you exactly how many inserts,deletes,updates have taken in a table.

    You just cannot insert in a table and see the readings on dba_tab_modifications immedtialy.These readings will be seen when smon wakes up .As and when smon wakes up it will update the dba_tab_modifications .for testing purpose you can shutdown the database and startup then you will get the readings....Otherwise normally for 3 hours or once ot will smon will wake and update...

    Audit will not give any data's that in a table 5 rows has been inserted,10 rows deleted ,8 rows updated ...

    where as monitor option you know all these.Further it is so simple to use...

    This is a cool feature (monitoring). The biggest pain is waiting for SMON to wakeup. Anybody know of a way to force SMON to wakeup?
