OEM Report: Last 6 month Database Space Usage and Growth

Hello All!
So I had worked in some very useful reports to have in OEM. In next weeks I’ll share some code you may like… 🙂

To create it? Enterprise -> Reports -> Information Reports. There are several nice default reports there you me like.

Now, let’s go to the first Report, as per title:

1. First you Select the Database:

Select_DB.png

2. Then you see the report:

Report3

That’s nice, right?
Here is a report for another database with actual 640GB average growth per month (its expected, once DBSize is over 60TB):

Growth

So, Mat, can you share the queries? Of course:
