I have been asked to look into monitoring what tables are being used in our DW.
It is a broad question. We have tonne of objects that we need to clean up. I think I will be more interested in tables that are being read than written into because we may be writing into tables in a nightly batch that is not being used.
There is a table called V$segment_statistics that stores this kind of information but only since db was last started. I am thinking I could write this view into table everyday before restarting db so that there is good data to analyze over the period of time.
Are there any other better ways to do it?
