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.

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
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?
