I recently upgraded from 11.6 to 12.0, and noticed the Administer->Tablespaces grid now displays all tablespace sizes as “MB” or “GB” or “TB” (depending on magnitude of that space). At first glance, I thought this would be fine; perhaps even preferable. However, I’m not hitting a problem. One of the ways I made use of this display was to track the rate at which massive load operations were adding data to a particular tablespace. Crude? Yes, admittedly. But for “quick pulse check”, it was a very handy means to check that mass-load operations were performing as expected - just open the Tablespaces grid, hit “refresh” a few times, and check how quickly “Free Space” was dropping in my tablespace (while simultaneously verifying that I wasn’t approaching 100%, that TEMP wasn’t blowing up, etc.).
Sadly (for me), with the more user-friendly rounded-display, I’ve lost the ability to do this - a 5 TB tablespace shows my used/free spaces as unchanging 1.43 TB/3.57 TB, not in MB, so I can’t get a good “at a glance” feel of approx MB/sec a load is running at. Is there any way to revert the grid to display all sizes in MB, as it did in 11.6?
