Hi Sam,
we are using syncrepl mechanism, and we don't decide yet if the consumer will point to a specific IP ( let's say half of consumer on multimaster1 and the rest on multimaster 2) or pointing to Virtual IP of a RADWARE that is in charge of balancing ( only failover not load balancing).
In any case, I have to implent or found a solution more general as possible, in order to handle the two scenarios.
If you have any suggestion or something already implemented I will appreciate your help.
Best Regards, Andrea

Hi All, I work on an important infrastructure of 20 LDAP Servers, One Producer

19 consumers. We are migrating on multimaster-mode achieving 22 server, 2 Producers (

the
LDAP servers are synchronized. We want to create some tools for checking periodically whether there is
some
consumer not yet synchronized or not. Could you suggest me something? We were thinking on analyzing entryCSN, however if we are going to
analyze
all of them could lead in an overload problem since we are dealing with
more
then 3 Millions of objects, and we want to check the sync at least every
X
minutes and not Hours or day..... Many Thanks in advance
Hi Andrea,
I wrote a Python script that compare the contextCSN values of a provider and its consumer. I have noticed that in the mirror mode configuration the contextCSN attribute on the providers hold multiple values.
I am working on migrating my OL platform to a similiar setup (but with less read-only consumers). Which replication method are you using: syncrepl or delta-syncrepl? Are your providers sharing a virtual IP address with the help of a heartbeat failover mechanism and are your consumers replicating using this specific IP address?
Thanks.
