But what can I do if resolve_initial_references throws no resources system exception ?
Is it possible to call ORB_init and resolve_initial_references with another, correct parameters, created at runtime with host name or port number entered by user ? Or I can only
exit the application with error information and then try to connect again ?
It all comes from the situation wher host name and port number of  omninames server are not taken from config file, but have to be entered by user of client application.
