Try using postgres, Heroku is well known to work with it

ok can u tell me how can i chage to sqlite3 to postgres for the
application that i have already developed..infact i does not need any
database(for this particular application) as all my webpages are
static ones,...

You don't need to, since Heroku knows how to find its own database.
Just make sure you're not requiring the sqlite3 gem.

infact i does not need any
database(for this particular application) as all my webpages are
static ones,...

Then don't use Rails or Heroku. Just upload the static HTML files to
your ISP's hosting space and have done with it.

Best,
