3794.0. "Implementation questions" by ISIDRO::MAMORENO () Thu Sep 24 1992 08:17

    Hello, I have some questions on DECmcc:
                                           
    
    - How can we add a new object from an external source ? Do we
      have a GDMO translator to MSL ? Is it done like with ASN.1 for SNMP ?
    
    - How can we find/browse instance objects within the MIB ? Can we find
      any object and show characteristics, etc. in a reasonably time and
      easily ? 
    
    - How instance objects are structured in the MIR ? Are we using "ISO
      instance Identifications" in a named tree (see following)?
    
                             o
                            / \
                           /   \
                     FDN  o     o  RDN          
                         / \   / \              AVA (Attr.Val.Assertion)
                        /   \ /   \
                       o           o
    
    
    - When will be available the Director <--> Director dialog ? Any date ?
    
    
    Thanks and Regards.

    Miguel,
    
    - How can we add a new object from an external source ? Do we
      have a GDMO translator to MSL ? Is it done like with ASN.1 for SNMP ?
    
    We do not have such a translator yet. To date, all such translations
    from GDMO to MSL have been done via humans.
    
    - How can we find/browse instance objects within the MIB ? Can we find
      any object and show characteristics, etc. in a reasonably time and
      easily ? 
    
    There's a tool known as DAP (for Dictionary Administrator Program)
    which is used for maintaining the dictionary. While it was not designed
    to operate as a general-purpose browser, you can use it, as we do, to
    wander around the dictionary. Documentation is contained in the DECmcc
    Toolkit documentation.
    
    - How instance objects are structured in the MIR ? Are we using "ISO
      instance Identifications" in a named tree (see following)?
    
                             o
                            / \
                           /   \
                     FDN  o     o  RDN          
                         / \   / \              AVA (Attr.Val.Assertion)
                        /   \ /   \
                       o           o
    
    Instances are formed into a tree - however, unlike OSI which uses a
    scheme similar to that of OSI Directory Services (aka X.500) based on
    AVAs, DECmcc uses the EMA scheme of class containment, and naming
    based on sequences of Class,Instance pairs. Thus, one might have an
    entity:
    	NODE dec:.lkg.foo CSMACD PORT bar
    where NODE, CSMACD, and PORT represent classes
    and dec:.lkg.foo is a specific instance of NODE
    and bar is a specific instance of PORT
    Note that use of upper and lower case above is just to help you - mixed
    case is more normal.
    You might want to read the EMA Entity Model for a more detailed
    description of how entities are named and how containment works in EMA.
    
    
    - When will be available the Director <--> Director dialog ? Any date ?
    
    This is still the topic of on-going discussions as part of the budget
    process, so we don't have a date for you right now. However, I can tell
    you that it is not part of the DECmcc V1.3 development which is
    underway.
