RE: .0
The configuration information (both IDENTIFIER and REFERENCE) is stored
in DNS.
The REFERENCE information is stored in a DNS object's attribute
in the ILV-encoded format. (the attribute is the Binary attribute,
and cannot be seen using DNS$CONTROL program. But, the "dnscp"
program on Ultrix DECnet/OSI does display the binary attribute.
The reference information is removed when you delete the DNS
object.
Suppose you create a domain called .site1.foo, MCC creates two
DNS group objects - .site1.foo and .site1.foo_MCC_EXT000.
Since there is the limitation in record size for storing one
DNS object, MCC creates the first 10 members in the 'primary
domain' (.site1.foo), and the next 80 members in the first domain
extension (.site1.foo_MCC_EXT000), and another 80 members in the second
domain extension (.site1.foo_MCC_EXT001), and so on. The second and
consequent domain extensions are created on-demand.
If you want see all members of a domain .site1.foo in
DNS$CONTROL, do following until domain extensions are exhausted:
DNS> show object .site1.foo attribute DNS$MEMBERS
DNS> show object .site1.foo_MCC_EXT000 attribute DNS$MEMBERS
DNS> show object .site1.foo_MCC_EXT001 attribute DNS$MEMBERS
....
When you add a member to a domain, MCC performs two tasks:
1. Add the members fullname to Group object's DNS$MEMBERS attribute
2. Add the domain name in the member's MCC_DOMAIN_LIST attribute.
The attribute contains the list of domains the member object
belongs to.
The following is what you can do to remove V1.1 information:
1. Use DNS$Control program to find the Domain list to which a
ICMP_AM object belongs, and remove the ICMP_AM object from the
domain (group object). Assume that the ICMP_AM object is
.site1.foo, and it belongs to .domain.bar1 and .domain.alpha.
DNS> show object .site1.foo attr MCC_DOMAIN_LIST
(* This is shown in 'ASCII and Hexadecimal' format)
DNS> remove member .site1.foo group .domain.bar1
DNS> remove member .site1.foo group .domain.alpha
2. Use DNS$Control program to delete ICMP_AM objects:
DNS> delete object .site1.foo
3. If the ICMP_AM has Alternate Identifiers, there are DNS softlinks
in .MCC_ICMP_Backtranslation directory. Please delete these
softlinks.
DNS> show dir .MCC_ICMP_Backtranslation known link
DNS>! for each known softlink:
DNS> delete link .MCC_ICMP_Backtranslation.--------
DNS> delete link .MCC_ICMP_Backtranslation.--------
DNS> delete link .MCC_ICMP_Backtranslation.--------
DNS> delete link .MCC_ICMP_Backtranslation.--------
