I've got the following layout Picture Cluster
RZ West is my first data center A and
RZ Ost my second data center B. As you can see one secondary database of each cluster is available in the other data center.
Is it possible to read data out of
Secondary 2 OST (B) and add it to the master database
Primary WEST (A) automatically?
