1857.0. "DECmcc in a common namespace" by IDEFIX::MCCORMICK () Wed Nov 27 1991 07:27

    
I do NOT understand the technicalities of DECmcc but as I am knowledegable on
DECdns I frequently am asked whether customers should use a common namespace 
for all DECdns applications. I believe that they should but that they need to 
understand what to avoid when managing node objects, for example, which could 
cause problems for other applications. Unfortunately, I do not understand 
DECmcc enough to answer this question. 

so my questions...

Can DECmcc use node objects which already exist in the namespace ?

I assume that it will add specific attributes but in doing so, will it preserve
all attributes which the node object already has ?

Are there DECmcc functions which will cause me to lose non-DECmcc specific 
attributes ? (How can it delete attributes without deleting the object ?)
                                                                 
regards, Pat

1857.1What a Good Question...SEDOAS::BESTWed Nov 27 1991 08:545
    Hi Pat, this very same question has just been posted in the
    Netmgt_Europe conference on node Bonnet. I think it would be very
    useful to cross post this question in that conference.
    
    Many Thanks...Peter B

.0> Can DECmcc use node objects which already exist in the namespace ?
    Yes, though for MCC to work, it requires additional namespace
    attributes. This is accomplished by Registering the node with MCC.
    (The software is set up so that if you register with MCC you don't have
    to do anything else to DECnet - ie. MCC Register is a superset of the
    NCL Register command.)

    None that I'm aware of.

Just for clarification...

My node object already exists. I THEN register this node with MCC. It will
add the additional namespace attributes to the existing object.

Correct ?

The only danger would appear to be the fact that either NCL or MCC can delete
this node object - this is what needs to be controlled.

    Hi Pat,
    
    yes, you are right: 
    if you perform a 'mcc> REGISTER NODE (or NODE4) .dir.name SYNONYM name',
    then DECmcc will simply add some mcc_* attributes, eg mcc_uid,
    mcc_class if the objects exists already. If the object does not exist,
    then DECmcc tries to create an object as decnet_dns_register would do it.
    
    The problem is actually  the DEREGISTER directive and the icons to
    remove an entity from a domain. One icon is for removal of an entity from a
    domain, the other one removes the entity from the domain  AND  deregisters
    the entity.
    
    Next time in Valbonne ? :-)
