Synchronizing DirXML Drivers
After creating BCC-specific DirXML drivers and SSL certificates, if you are adding a new cluster to
an existing business continuity cluster, you must synchronize the BCC-specific DirXML drivers. If
BCC-specific DirXML drivers are not synchronized, clusters can't be enabled for business
continuity. This is not necessary unless you are adding a new cluster to an existing business
continuity cluster.
To synchronize BCC-specific DirXML drivers:
1 Start Internet Explorer 5 or later and enter the URL for iManager.
The URL is http://server_ip_address/nps/imanager.html. Replace server_ip_address with the
IP address or DNS name of the NetWare 6.5 server that has iManager and the DirXML
preconfigured templates for iManager installed.
2 Enter your username and password.
3 In the left column, click DirXML Management, then click the Overview link.
4 Search for and find the BCC driver set.
5 Click the Cluster Sync icon and then click the Synchronize button.
6 If you chose to include User object synchronization, repeat the above steps, and in
the User Sync icon.
Preventing DirXML Synchronization Loops
If you have three or more clusters each in separate eDirectory trees in your business continuity
cluster, you should set up DirXML user object and cluster resource object synchronization in a
manner that prevents DirXML synchronization loops. DirXML synchronization loops can cause
excessive network traffic and slow server communication and performance.
For example, in a three cluster business continuity cluster, a DirXML synchronization loop occurrs
when cluster one is configured to synchronize with cluster two, cluster two is configured to
synchronize with cluster three, and cluster three is configured to synchronize back to cluster one.
This is illustrated in Figure 2-3
