oracle tns 文件，方便连接远程oracle数据库

TEST =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = leohuang)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = test)
    )
  )

ASF =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ASF02)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ASF)
    )
  )


用下面的话，就可以在php中访问连接了
$conn = oci_connect('asfcms', 'beehive', 'ASF');
if (!$conn) {
  $e = oci_error();
  print htmlentities($e['message']);
  exit;
}
