In my local server(WAMP) it´s ok, the application work, only on new server ubuntu appear this error;


The simple code that work´s

$instancia = "(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = host)(PORT = 1521))(CONNECT_DATA = (SERVICE_NAME = service)))";

$conn = oci_connect('user', 'pass', $instancia);

if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$stid = oci_parse($conn, 'SELECT TIPO FROM tabela WHERE COD = 8002');
oci_execute($stid);

$row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS);
var_dump($row);exit();
