Tablespace usage pattern

Gurus,
what i need to find out is which tablespace tends to demand the most space,showing the growth pattern for each TS over the last week or so. determine the TS that’s grown the most and by how much over the last couple of weeks.How can i generate such a report?

as far as I know there is no such reports exists. you need to maintain spread sheet with growth rates every week.

However, if you want to find the growth trend for a particular object based on the current load you can use the below procedure.

Quote:

---

select * from table(dbms_space.OBJECT_GROWTH_TREND ('SCHEMA','OBJECT NAME','OBJECT TYPE'));

Thanks,

How accurate is this. I have a table defined like this (see below).

Today at 4PM, it had 10 million rows in it. I deleted approx to 91,000 rows and ran the report again and I still get the same numbers for 8/2 and 8/3 after the delete. At the minimum I would suspect that the space_usage should have decreased.

What am I missing?

agree with you. did you run this immediately after delete?

Thanks,
