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. -- Sam
