I don't know where you have oclock from, so I cannot look up the values
for you. Please run xclock, then run xprop in a terminal and click on
the xclock window. xprop will return info about the program in the
terminal. The values of WM_CLASS(STRING) match application name and
class in the openbox configuration. Example:

WM_CLASS(STRING) = "xclock", "XClock"

first argument is name, second is class, so it becomes 

<application name="xclock" class="XClock">

This is how I get xclock into the top right corner:

    <application name="xclock" class="XClock">
      <decor>no</decor>
      <shade>no</shade>
      <position>
        <x>-0</x>
        <y>0</y>
        <monitor>1</monitor>
      </position>
      <focus>no</focus>
      <desktop>all</desktop>
      <layer>below</layer>
      <iconic>no</iconic>
      <skip_pager>yes</skip_pager>
      <skip_taskbar>yes</skip_taskbar>
    </application>
  </applications>

as you see I have changed the position (-1) and the layer (below).

Kind regards,
Christoph
