After modifying the Size of a datafile to 1.05 TB from 1.04 TB, the Size display switched to GB, but the modification was indeed made in TB
I modify to 1,05 TB
After click on OK, I have the window 10-20 seconds :
But the file size is good with 1,05TB :
We can't modify the tablespace to "1,05 TB". Oracle doesn't take that command with decimal places. So we do some math:
1,05 TB * 1024Gb/TB = 1075,2 Gb
But Oracle can't take the ,2 either, so we drop that.
Then we run: Alter database datafile blah resize 1075G
I see in your screen shot that we changed the units, but not the value in the dialog. I'll take a look at that. Thanks for reporting it.
No, the unit changed by itself after the click
