Technical Aspects of the Transitional Process
Data Input• Flat file in RPSL format• 3 object types (ARIN old DB)
– Aut-num– Inetnum– Person
• Entity is an attribute of the 2 services objects• No strong “ownership” relation between
service objects

Technical Aspects of the Transitional Process
Data Manipulation• Two temporary object (OldEnt and OldId) were created to import
the data• During the import an algorithm cleaned up the “owner” name and
compared them between the 2 services objects. The cross relation was got from these information. Name clashes were treated by manual processing.
• The adopted transition schema provides only full whois and reverse publication services until the update of the information is made.
• Block boundaries were adjusted to prefixes.• Represented reverse delegation on the Whois were adjusted to
prefixes and represent exactly the requested reverse delegation.

Migration / Verification• The process took 2 weeks between the arrival
of the first dump and the take over of the reverse zone file generation and publication
• After the final import the data was verified by independent reverse publication(ARIN and LacNIC) and objects count.

Transition Schema• To update the data the customer need to contact RSG.• The customer receives a password and could update the
information directly on the system.• During the update the “owner” data is imported in a final object
and the customer receives full services directly on the system interface.
• The adopted policy to provide smooth transition is:– Customer is allowed to update the data on request– Customer is obligated to update the information during new
allocation.• So far we have 10% of the database updated.

Data Protection• Database replicated online. • Read load separated from master database• Two full flat file backups during the day• One daily copy on tape to a safe• External online replication
