Hi Everyone,
I’ve set up a new 389 DS cluster (389-Directory/1.3.6.1
B2018.016.1710) and have set up a replication agreement from our old
cluster (389-Directory/1.2.11.15 B2014.300.2010) to a master node in
the new cluster. Problem is that updates in the old cluster take up
to 15 mins to make it into the new cluster. We need it to be near
instantaneous, like it normally is. Any ideas what I can check?
I am assuming you don't have a replication schedule enabled?
In LDAP replication is always "eventual". So a delay isn't harmful.
But there are many things that can influence this. Ludwig is the
expert, and I expect he'll comment here.
Only one master may be "replicating" to a server at a time. So if your
1.3 server is replicating with other servers, then your 1.2 server may
have to "wait it's turn".
There is a replication 'backoff' timer, that sets how long it tries and
scales these attempts too. I'm not sure if 1.2 has this or not though.
Another reason could be there are no changes to be replicated,
replication only runs when there is something to do. So your 1.2 server
may have no changes, or it could be eliminating the changes with
fractional replication.
Finally, it's very noisy but you could consider enabling replication
logging to check what's happening.
I hope that helps,
Thanks a lot,
Trev
