The following example defines a replication hierarchy that includes denver, boston, and miami and, whose root is usa.
cdr define server --connect=boston --nonroot --init \ --sync g_usa g_boston
The backslash (\) indicates that the command continues on the next line.
cdr define server -c denver -I -N --ats=/ix/myats \ -S g_usa g_denver
This command uses short forms for the connect, init, and sync options. (For information about the short forms, refer to Option Abbreviations.) The command also specifies a directory for collecting information about failed replication transactions, /ix/myats.
cdr list server
The root server usa is fully connected to all the other root servers. Therefore usa knows the connection status of all other root servers and of its two child servers, denver and boston. The command returns the following information:

cdr list server --connect=denver
The nonroot server denver has a complete global catalog of replication information, so it knows all the other servers in its replication system. However, denver knows the connection status only of itself and its parent, usa.
The command returns the following information:

cdr define server -c miami -I --leaf -S g_boston g_miami
cdr list server -c miami
As a leaf replication server, miami has a limited catalog of replication information. It knows only about itself and its parent.
The command returns the following information:

cdr list server g_usa
The server is a hub; that is, it forwards replication information to and from other servers. It uses the default values for idle timeout, send queue, receive queue, and ATS directory.
The command returns the following information:
