2062.0. "Variant information cannot be retrieved??" by COL01::LUNT () Fri Jan 10 1992 07:19

    Hello,
    
    	I have registered serveral PC's as stations using a command
    procedure that attempts to register the PC, if the PC is currently
    reachable, it is registered and the references are set, if not the
    procedure reques the PC and trys again 4 to 5 hours later. Lately
    we have started placing these registered PC's in the iconic
    map. All goes well until someone tries to do a show references, then
    we get the error:
    
    Management Window Message: Variant information for this entity cannot
              be retrieved.
    
    So I go to our trusty messages manual and get the following
    explanation:
    
    Explanation: Thie Iconic Map could not retrieve variant information.
    DECmcc uses variant information to determine the form fields,
    operations, and child entities are displayed.
    
    User Action: Verify that the entity is stored in the Registration
    Database by issuing the Directory directive. Register the entity
    if it isn't.
    
    Great, now I am no further ahead then before I read the manual. We are
    only end users here at my customer site. The entity is registered, or
    how could I have placed it onto the Iconic Map in the first place?
    Secondly, the Directory and Show all references directives work fine
    in the command line interface. So what next?
    
    I'm getting very tired of the messages manual. I don't know how
    many times it has told me to "Contact my digital representative". I am
    the digital representative!!
    
    I am using V1.1

2062.1Could you supply some log for further info?TOOK::TANEd TanFri Jan 10 1992 13:1973
    Hi,
    	When you do a show references from the Map, the Iconic Map PM will
    call Config FM (REGISTRATION FM in V1.2) SHOW REFERENCE attribute entry
    point for the reference attributes and then a call to Config FM
    GETVARSELECTOR entry point to get the Variant Information. In the case
    of STATION the variant selector is the attribute Functions Supported
    (id code 1 and datatype is an enumeration 
    
     TYPE
        FunctionSupportType = 1050 (
          ENETV2_Only = 1,
          IEEE802_Only = 2,
          DEC_ENETV2 = 3,
          DEC_IEEE802 = 4
          );
    
    )
                                                                   
    	Would you please post the log of the following in here:
    
    1)  Log of your REGISTER command to register the PC as a station
    
    		REGISTER STATION <station-name> ADDRESS xx-xx-xx-xx-xx-xx,
    			FUNCTION SUPPORTED = <function>,
    			ALTERNATE ADDRESS = yy-yy-yy-yy-yy-yy
    
    
    		Use the ALTERNATE ADDRESS (DECnet physical address) if the
    		station is running DECnet Phase IV.
    
    
    2)  Log of a DIRECTORY STATION on this PC station using first the
    	fullname and then the address
    
    		DIRECTORY STATION <station-name>
    		DIRECTORY STATION xx-xx-xx-xx-xx-xx
    
    3)  Log of a SHOW STATION for the FUNCTION SUPPORTED attribute
    
    		SHOW STATION <station-name> FUNCTION SUPPORTED
    
    		SHOW STATION xx-xx-xx-xx-xx-xx FUNCTION SUPPORTED (if not
    							running DECnet IV)
    
    			or
    
    		SHOW STATION yy-yy-yy-yy-yy-yy FUNCTION SUPPORTED (if running
    								   DECnet IV)
    
    
    4)  Log of GETVARSELECTOR STATION call. (The GETVARSELECTOR directive
    	in V1.1 is not documented but works from FCL, but in V1.2 it will
    	not work from FCL anymore)
    
    
    		GETVARSELECTOR STATION <station-name>
    
    		GETVARSELECTOR STATION xx-xx-xx-xx-xx-xx (if not running
    								DECnet IV)
    
    			or
    
    		GETVARSELECTOR STATION yy-yy-yy-yy-yy-yy (if running DECnet
    								IV)
    
    
    
    			You will get something like
    
          		Functions Supported = DEC_ENETV2

Hello, 
	Irecieved the following information from my customer in
regards to the Problem at hand. We just upgraded to V1.2 and he
is going to try the same procedure in V1.2 when he has time.
Sorry for the delay, but V1.2 is keeping us very busy and this
problem is not at the top of the Customers priority list.

2062.4NS corruption + AltAddr misunderstanding?CHRISB::BRIENENDECmcc Bridge|Station|SNMP Management.Fri Jan 24 1992 14:2842
 Following comments are in the context of DECmcc V1.1:

 1) REGISTER STATION fullname1 ADDRESS=addr1, ALT ADDR=addr2

    Note that in this command "fullname" and "addr1" are
    Identifiers, while "addr2" is NOT (it's a Characteristic).
    What this means is that the command:

       DIR STATION fullname1   or   DIR STATION addr1

    Should return BOTH "fullname1" and "addr1", but not "addr2".
    Furthermore, the command:

	DIR STATION addr2

    ...should fail, since "addr2" is not an identifier (and not
    stored in the NameSpace). Note also that the DIR command
    never gets to the Entity (it's handled by the REGISTRATION FM,
    which goes to DNS to get the identifiers).

 2) Since DECmcc V1.1 did not implement "Partial Registration",
    the REGISTER STATION command should either:
      1. fail completely, not changing the namespace or
      2. succeed, putting the Name and Address in the namespace
         for the DIRECTORY command to access.

    The commands given below indicate that the FullName is
    there, but the Address is not (the DIR command should
    always return BOTH identifiers). This sort of response
    indicates (to me) that the namespace is corrupted.

 3) The fact that the particular Station is not accessible via
    "addr1" or "addr2" (i.e. "cannot communicate with target")
    on a SHOW command has nothing to do with the DIR command
    (see above).

 4) It is implied that the REGISTER and SET commands actually
    succeeded. Does the following command work:

	SHOW STATION fullname ALL REFERENCE

    Did the REGISTER command actually succeed when it was issued?
