I am not able to see users account status when connected to the database as Database Vault Owner or Database Vault Account Manager account using Toad, although I am able to successfully run "select account_status from dba_users" on the same section.
Has anybody ever had such scenario?
Can you provide a screen shot of what you are missing?
Edit:
It sounds like Toad thinks that you don't have privileges to select from the DBA_ views and is selecting from ALL_ instead. ALL_USERS does not have the STATUS column.
That might happen if there is some error when Toad is making its privilege checks immediately after a connection is made.
Try this:
Start Toad but don't make a connection yet.
Go to Database -> Spool SQL -> Spool to Screen. This will capture all of Toad's internal SQL.
Now make your connection and go to Schema Browser -> Users, and select a user
Post the Spool SQL output here (or send it to me in a direct message if you prefer)
