IssueNotes Decision
1Is FDN optional?Is it possible to register a cmHandle without an FDN?

Toine Siebelink Yes it is optional as not everyone will use it

2In Hazelcast what is the key?Is it the FDN or the cmHandleId?

Toine Siebelink create 2 maps:

  1. alternate id → cm-handle-id
  2. cm-handle-id → alternate id
3Check alternateId in 'updatedCmHandles'Assuming updatedCHandle should NOT be used to correct/change the AlternateId for a CmHandleId

Alternate IDs are immutable once they are set.
However if a previously created CM Handle's alternate ID is not defined then an update should be possible.
The only way to change this value is to delete the current CM Handle and then re-register it.

4Should we persist the alternateId?Should we modify the registry model?

Toine Siebelink Yes, the Inventory Model should update with the AlternatId as detailed below

5Alternative ID is NOT unique!multiple NMs might be using same subnetwork names i the FDNs and as NCMP manage multiples NM's NCMP can encounter duplicates.

kieran mccarthy FDNs will be Unique 

6Add a cm Handle with a alternate ID that is already in use (for another CM Handle)

Error report solution will be easier if we do NOT add it and treat it like a 'normal' duplicate cm handle

kieran mccarthy do not add! Rephrase error to
'CM Handle Id or Alternate ID already in use'
