Frequently asked questions

Here are answers to some frequently asked questions about symmetrical clusters.

Why can't I monitor the root Domino® data directory so that repair can fix system databases?
Many system databases have specialized recovery processes. For example the Cldbdir server task automatically recreates cldbdir.nsf if it doesn't exist. Enabling repair on system files would cause multiple mechanisms to fix a problem and lead to unpredictable results.
Can content other than databases and DAOS objects be repaired?
No, other types of content such as application data files and HTML files aren't repaired.
Are database templates repaired?
No, databases templates (.ntf) files and forms files, for example, Forms9_x.ntf, are not repaired.
What if I have widely geographically distributed clusters with limited bandwidth?
Repair assumes that all cluster mates are equal donors and it distributes repair requests to all available cluster mates. Repair tends to assign more work to donors who respond faster but it doesn't weigh donor availability or cap requests based on bandwidth.
Does repair work if I use database or directory links?
Symmetrical clusters are not supported for databases that are accessed through directory or database links.
Does the server file system look the same after repair?
There is no change in folder structure on a server after database repair due to folder symmetry across cluster mates. Replica size may change, though. For example, if a replica on Server A that was not compacted is replaced with a compacted replica from Server B that is smaller, the new replica on Server A is smaller than the original.
Should I continue to do backups after enabling a symmetrical cluster?
Yes. Although the feature should significantly reduce the number of times you need to use your backups, maintaining proper backups of your data is essential to your business.
