Oracle Enterprise Manager rounding tablespace size?
Does Oracle Enterprise Manager round values or am I missing something in my SQL query?
OEM is showing the tablespace size for SYSAUX as 2GB. But, when I query the dba_data_files table, I get 1940 MB. You can see the query I'm using in the image below.
Solution
Have a look at this topic: Binary prefix
You have 2,034,237,440 Bytes.
When you do 2,034,237,440 / 1024 /1024 then you get 1,940 MiBytes (not MBytes!)
2,034,237,440 Bytes is equal to 2.034237440 GBytes, I assume this is just rounded to 2 GB.
However, Oracle Enterprise Manager may does the same error as so many other people, see section Inconsistent use of units
