Hi Peter,
In Toad 12.10, we switched to DBA_LMT_FREE_SPACE because we had reports from several users that DBA_FREE_SPACE was painfully slow. I figured that even though it does not include recyclebin objects, the difference in result would be relatively small and the improved time to the SB would be welcomed. If you need a more precise measurement, here are a few options, perhaps in the order of difficulty...
- Purge the recycle bin, at least for the tablespace in question.
- Pull down the Toad 12.11 beta and use that instead. In the beta, the SB Tablepsace filter option "Include usage info" has been changed from a checkbox to a dropdown that allows you to exclude usage, or include it, specifying to use either DBA_FREE_SPACE or DBA_LMT_FREE_SPACE. Database -> Administer -> Tablespaces also has an option to specify which view to get free space info from.
- Use Spool SQL to grab the query that we run, paste it into the Editor, and swap the subquery that includes DBA_LMT_FREE_SPACE with the following, then just run it in the Editor.
(select tablespace_name, sum(bytes) bytes_free
from DBA_FREE_SPACE
group by tablespace_name) b
- Create a role for your users that does not include DBA_LMT_FREE_SPACE and grant that instead of SELECT_CATALOG_ROLE or DBA or whatever privilege you are using. Toad will revert to DBA_FREE_SPACE if you can't select from both DBA_LMT_FREE_SPACE and either SYS.TS$ or V$TABLESPACE.
Sorry for the inconvenience. As you see, we've taken care of it in the current beta and for Toad 12.11.
