| 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.
