How about creating a results table and putting insert triggers on each of your two existing tables. The results table could have one field for the date, one for the time interval and one for total users. A person logging on would cause the counter for that date and time segment to be incremented. Someone logging off would decrement the same field.

An alternative would be to just perform a count from v$session at some point in the five minute interval and save the total number of records to a report table.

select count(*)
from v$session
where username is not null;
