2694.0. "DECmcc T1.2.4 & local DNS attributes for DOMAINS" by ZTOIS1::VISTA (Renato VISTA, SIS Strasbourg, France) Mon Apr 06 1992 07:38

    
    Hello,
    
    On a DECmcc/ULTRIX T1.2.4 RISC platform without DNS (ie using DNS local
    emulation), how is it possible to retrieve local DNS attributes,
    especially MCC_UID for DNS MCC domain objects ?
    
    As the MCC_UID of DOMAIN DNS objects is used to build MAP files with
    the following syntax :
    
    		MCC_<mcc_uid_in_reverse_mode>.MCC_MAP_<domain_name>
    
    when a domain is deregistred and registred again (from a DECmcc/VMS
    BMS V1.1 to a DECmcc/ULTRIX T1.2.4 enviromnent), the MCC_UID is
    recalculated and the previous MAP files are becoming unsable directly,
    so a renaming operation is necessary as following :
    
    #mv mcc_<old_mcc_uid>.MCC_MAP_<domain> mcc_<new_mcc_uid>.MCC_MAP_<domain>
    
    Thank you for your replies.

2694.1Dont need the UIDTOOK::R_SPENCENets don&#039;t fail me now...Mon Apr 06 1992 15:3917
    Your problem is actually more easily solved than you think.
    
    To move a map file from one domain to another (even of the same name
    but with admittedly a different UID, do the following;
    
    For a map for, lets say a domain named LKG2-A
    
    rename mcc_maps:MCC_1116000400AA000001CAA28C166F6240.MCC_MAP_LKG2-A
    to mcc_maps:MCC_LKG2-A.MCC_MAP
    
    When you later open the new LKG2-A  domain, mcc will first look for a
    UID based map file name, failing that, look for one in the form
    	MCC_domainname.MCC_MAP.
    
    This is in the V1.1 DECmcc documentation.

2694.2OK for MAPs, but what about local DNS attributes ?ZTOIS1::VISTARenato VISTA, SIS Strasbourg, FranceTue Apr 07 1992 07:3912
    
    Hello Rob,
    
    And thank you for your reply.
    Effectively, this way of renaming MCC maps runs correctly, but I've not
    find any information in the BMS V1.1 documentation about that...
    
    Nevertheless, is there any way of getting DNS attributes of MCC objects 
    in a local DNS environment (without DECnet OSI installed) ?
    
    Regards,
    Renato
2694.3What are you looking for?TOOK::R_SPENCENets don&#039;t fail me now...Tue Apr 07 1992 17:527
    Gee, I don't know any way to get DNS attributes of MCC objects even
    using real DNS. What are you looking for in the Local Namespace?
    
    The discussion on mapfile names was sorta burried on page 3-26 of the
    DIRECTOR use manual.

2694.4Why DNS is useful...ZTOIS1::VISTARenato VISTA, SIS Strasbourg, FranceWed Apr 08 1992 07:1970
    
    
    Hello,
    
    Ok for the documentation, but it's not very clear !!!
    
    What am I looking for in DNS ?
    
    In fact, I'm not looking for...but I'm controlling very often DNS MCC
    related object attributes such as following :
    
    
    $mc dns$control	(VMS...)

    This kind of attribute if very useful when there is a asynchronous
    problem between MIR *.dat files, DNS (or local DNS) name space, and
    MCC_<mcc_uid>.MCC_MAP_<domain_name> files, specifically because DECmcc
    seems to do relational links between global entities and domains (and
    this problem occurs often enough on Customer site...).
    
    MCC_UID can also be got via DNS$CONTROL (VMS)...

2694.5TOOK::R_SPENCENets don&#039;t fail me now...Wed Apr 15 1992 11:576
    Intersting information but I don't think you addressed my question.
    
    What are you looking for in DNS? I see what you displayed (and by the
    way, what version of DNS are you using to do that?).
