1469.0. "%MCC-E-NOPARENT... why?" by MLNEDU::GIAMMARINI (Roma Caput Mundi) Mon Sep 09 1991 13:28

    	Hi everybody, when I'm trying to register a new domain using the
    Iconic Map sometimes the MCC send this error message:
    
    %MCC-E-NOPARENT, parent entity does not exist
    
    so the domain is not created. To manage to create it I have to place
    inside the 'Member Type' field the value 'Static'. Note that it not
    always happens.
    Many Thanks

1469.1Need more information to be able to reproduce the problem.TOOK::A_MOORETue Sep 10 1991 20:1121
Domenico,

No parent errors can occur internally in the Domain FM they are then mapped
to the Common exception No Such Entity.  The parent would be the MAP domain that
the domain is being added to.  From the iconic map it should always exists or 
you can not open the map. 

When Dynamic domain members are created loop checking is done to be sure it
is a hierarchy.  No checking is done for static domains, so they can be used
for navigation or to limit notification roll up.

Do you have a multi clearing house dns setup?

What is the domain hierarchy structure .i.e does  the parent bellong to 
other domains?

Could the domain been deleted from another terminal?

Did the domain that was being added exist or was a new domain?

1469.2Problem solved (I hope!)MLNEDU::GIAMMARINIRoma Caput MundiWed Sep 11 1991 13:2429
    	Yesterday a collegue from Stockolm gave me a good input to solve
    the problem. He told me to look using the dns$control one attribute of
    the object domain. That is my domains structure from the MCC point 
    of view:
    
    	EDU_WORLD
    	  EDU_EUROPE
    	    EDU_ITALY
    	      EDU_MI
    		EDU_CED
    		  nodes
    
    Looking the attribute MCC_DOMAIN_LIST 
    
    	DNS> SHO OBJ EDU_CED ATTR MCC_DOMAIN_LIST
    
    the DNS tells me that the domain EDU_CED has two backlink with the
    domains EDU_MI and EDU_ITALY_BCK, but...the second domain doesn't still
    exist! Infact the guy from Stockolm told me that he had the same
    problem with a domain with no backlink towards the upper domains. I
    deleted the domain EDU_CED e recreate it and did a lot of attempts
    inside various domains to create new domains without any problem. 
    Note that the system I use is the tool to train the instructor to be
    able to train the MCC course, of course I'm the instructor, and I had a
    lot of problem with the DNS and MCC setup so probably some information
    was corrupted by my attempts.
    Many thanks to both
