You Asked

Hi Tom,

Please can you help me to identify the easiest method to figure out the users who had modified a Database Object like tables,indexes etc.

I am a new DBA and would be very helpful if you could advice.

Thanks,
Vish

By default, we dont track it.

You might want to consider the AUDIT command, or

a DDL logging trigger,

or you could do

alter system set enable_ddl_logging = true;

(but there are license implications on this last one).

Well...if you doing hundreds of ddl's per second, then *logging* them is the least of your problems :-)
