Resolution:
To partition the name servers based on the orbdomainName, you should: Start the name server and dump its IOR via its command line argument -dumpIOR OR -d OR -D (using this argument will cause the name server to dump its IOR and the exit restart the name server as normal cut and paste the IOR into a file (e.g. obnamsrv.IOR) Nameserver clients are then given the ORB parameter -ORBns_ior_filename obnamsrv.IOR To partition the name servers based on the host/port, you should use the following ORB parameters:
&ltbr>-ORBns_iiop (IIOP only mode) OR -ORBns_iiop_host (AND optionally &ltbr>-ORBns_iiop_port if a non-default port value is required)
&ltbr&gtPlease refer to Chapter 7 of the TIB/ObjectBus Programmers Guide for C   Programmers for a detailed discussion of the obnamsrv.
