Hello. I am trying to find a SQL query that will show me the total amount of free space that I have left within my database. I am database/system administrator, and when I receive requests to create a new table space, I would like to be able to check how much space I have left within my database through SQL developer, instead of having to check each Oracle database manually by remoting into the server and checking the free space on the hard drive. Thank you for your assistance.
