Establishes a new connection to an Oracle server and logs on.

<para>

Unlike <function>oci_connect</function> and

<function>oci_pconnect</function>, <function>oci_new_connect</function>
|

does not cache connections and will always return a brand-new freshly
|

opened connection handle. This is useful if your application needs
|
|
transactional isolation between two sets of queries.
