Make sure the publication server whose node is the parent of the master nodes of the replication system is running and has been registered in the xDB Replication Console you are using. See Section 5.2.1
for directions on starting and registering a publication server.
Select the Publication Database node corresponding to the master node that you wish to set as the master definition node.
Click the secondary mouse button on the Publication Database node and choose Set as MDN.
In the Set as MDN confirmation box, click the Yes button.
The selected master node is now the master definition node.
The value Yes
in the MDN field of the Property window indicates this database is the master definition node.
The new master definition node is moved to the top of the replication tree in the xDB Replication Console.
You should now perform a synchronization replication to ensure that the new master definition node is synchronized with the other master nodes. See Section 6.5.2
for directions on performing a synchronization replication.
