I am running a RedHat IdM environment and am having regular problems with missed
replications. I want to understand how it's supposed to work better so that I can make
reasonable hypotheses to test, but I cannot seem to find any in-depth documentation for
it. Every time I think I start to piece together an understanding, experimentation makes
it fall apart. Can someone either point me to some documentation or help me understand how
it works?
In particular, IdM implements multimaster replication, and I'm initially trying to
understand how changes are replicated in that environment. What I think I understand is
that changes beget CSNs, which are comprised of a timestamp and a replica ID, and some
sort of comparison is made between the most recent CSNs in order to determine what changes
need to be sent to the remote side. Does each replica keep a list of CSNs that have been
sent to each other replica? Just the replicas that it peers with? Can I see this data? (I
thought it might be in the nsds5replicationagreement entries, but the nsds50ruv values
there don't seem to change.) But it feels like it doesn't keep that data, because
then what would be the point of comparing the CSN values be? Anyway, these are the types
of questions I'm looking to understand. Can anyone help, please?
