In that case, you'd be looking at the last option - create a custom class
that is called from the OIR. The class would simply open the file and read
the next value. You could still use an Oracle sequence to keep track of
which line in the file to use next.
The file concept might be a little clumsy, however. Instead, you could
create a database table and populate it with two columns, an index and the
value. This would be a more efficient way of retrieving the numbers. You
would still use a custom class to retrieve the value from the database.
