The Python module is based on ESQL/C, which uses an entirely different
philosophy than JDBC. You can't expect to be able to translate a JDBC
connection string into an ESQL/C CONNECT statement.

There is NOTHING appropriate in the proposed documentation. Only this here:

ESQL/C applications don't connect directly to IP-Address/Port combinations.
They connect to abstractly defined servers that are defined in the sqlhosts
file. Information about how to write an sqlhosts file can be found on Google
by searching for "Informix sqlhosts file."
