4.1 Overview of Replica Creation

You use this three-phase procedure to create new VOB replicas:

1. Export phase-At one site, enter a mkreplica -export command, which creates a new replica object and a replica-creation packet.

2. Transport phase-Send the packet to one or more other sites.

3. Import phase-At the other sites, each administrator enters a mkreplica -import command, which creates a new VOB replica.

The procedure is similar for different methods of packet delivery and for different platforms. The example in this chapter assumes a high-speed connection between sites, and all replicas are located on UNIX machines. The procedure is the same if all replicas are located on Windows machines or if one replica is on a Windows machine; only the VOB-tags and pathnames are different.

If some replicas in your VOB family will be located on UNIX machines and others will be on Windows machines, be sure to read Replicating a VOB Between UNIX and Windows.
