I'm currently working on DECmcc V2.0 Distributed Directors. I'll try
to answer the first question. For DECmcc V1.2, directors do not know
about each other, and do not know how to talk to each other. This
isn't as bad as it sounds, because we use DNS as a network-wide
repository to share information between directors, so it "looks" as
though there is a lot of coordination going on, when there really isn't
much.
We are currently planning to use DECrpc (an implementation of OSF DCE-rpc)
to communicate between directors. (I believe that DECrpc will support the
OSI protocol for their V2.0 product.) For director specific information
exchange (kind of like introducing each other at a cocktail party), we
may end up using CMIP. However, I found that DNS (or some other global
nameserver) solves over 90% of information exchange problems because
you can just look up the information you need in DNS. The only time it
doesn't work is when the information you need is very dynamic (such as
needing to know whether a certain server (daemon) process is currently
running, or requesting some sort of statistic). In short, don't expect
CMIP to be used. And if it is used, it will probably be used very
little.
With DECrpc, we can select a preferred protocol for the rpc to run over.
I am currently planning to expose this to the end-user. This way the
end-user can state a preferred protocol for directors to talk to each
other. The software will be smart enough to figure out what protocol
to actually use by reading information out of the namespace (naturally,
it will try to use the preferred protocol first). TCP/IP is one of the
protocols which the user may select (other choices currently are OSI,
DECnet, and NCA).
Since this is mostly advanced development, expect it to change
significantly about a month from now.

No. The icon will remain (although it may change color as a result of
an alarm rule & notification services). It will not spew forth a an
animated bitmap of smoking network bits. :-)

Yes.

The only AMs that *I* know of with getevent support _right now_ are
the DECnet AMs.
I'll leave it to more knowledgable folk to add further information (or
correct mine, of course. )
