Unlike
normal tablespaces, true temporary tablespace information is not listed in
DBA_FREE_SPACE
Instead use V$TEMP_SPACE_HEADER view
SQL>SELECT tablespace_name, SUM (bytes_used), SUM (bytes_free)
FROM V$temp_space_header
GROUP BY tablespace_name
Open your terminal and type mysql -u root -p Enter your password. Hopefully your MySQL is logged in now.
