<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>This raises a problem: In some cases, a servant may
be passed a reference to a servant object located on its own service. In this
case, the processing needs to differ slightly to allow services to be redundant
mirrors of the same data. What I need is basically: If the object reference is to
the same database, don’t call remotely via the ORB, process locally, as
the servant may be loaded here.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>But how do I know it is local or to the same database?
I thought of using user generated IDs and code the database identifier (server.database)
in the object ID, but there doesn’t seem to be an easy way to extract the
object ID from an object pointer, as it seems to be located on the servant’s
POA only.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Because of backwards compatibility problems we can’t
easily change or extend the IDL to include a getLocation() method. So how would
one actually do it?<o:p></o:p></span></font></p>
