Example Two - One Adoptive Node for Two

 

Packages with File Lock Migration

 

This configuration has two packages, each owned by a different server.

 

The adoptive node for both packages is the same host. This sample

 

configuration uses the package control option, which prevents the

 

adoptive node from adopting another package if it has already adopted

 

one. Figure 3-3 illustrates this configuration.
