I did a session at CollabSphere on the Self-Healing Capabilities of Domino 10. The functionality added into Domino 10 for maintaining a healthy Domino environment is absolutely amazing. My presentation covers 5 issues that plague administrators on a day-to-day basis, how these issues are handled today and how these issues are remedied in Domino 10. The 5 issues I covered are:
- Issue 1: Missing replicas and NLOs
- Issue 2: Corrupt NSFs and NLOs
- Issue 3: Missing documents
- Issue 4: Critical views out of date
- Issue 5: Who Deleted my documents
If you utilize clustering in Domino, you will be applauding Automatic Cluster Database Symmetry. This functionality ensures both NSFs and NLOs are kept in sync across cluster mates. I have never worked with a customer environment that didn’t have missing NSFs on their cluster mates and I have found when DAOS is being used, inevitably there are at least a handful of NLOs missing on one or more servers. Automatic Cluster Database Symmetry ensures these discrepancies are repaired with no administrator intervention required once things are setup.
What’s even more cool is that if NLOs are encrypted with the server’s ID, the NLOs are decrypted with the source server’s ID, repaired/replicated, and then encrypted with the target server’s ID, provided NLO encryption is enabled (which is the default setting).
There is a new Cluster Configuration document that allows administrators to select which cluster to work with. Based on the chosen cluster, the Symmetrical Cluster tab of the new configuration document allows you to select which folders should be monitored by the server to maintain symmetry on. This allows you to keep both NSF and DAOS content synchronized across a cluster.

I would like to thank the HCL Development team, in particular Gary Rheaume, for all of their input on the content of the presentation. Gary was awesome and created two videos I was able to use during my presentation as demos. The great news is both of these videos are now available on YouTube!
The first demo is of Automatic Cluster Database Symmetry and can be found here: https://www.youtube.com/watch?v=8q-AWayRxwI
The second demo is of Automatic Database Repair and can be found here: https://www.youtube.com/watch?v=IKYLJWpEWBo
I will be creating additional blog posts regarding these amazing features coming in Domino 10.
