I am beginning to understand better some of the reasons that Oracle likes to review analyst publications before they go out. Notwithstanding what an Oracle executive told me Friday, I received an email from Irem Radzik of Oracle which said in part:
I am the product marketing director for Oracle GoldenGate product. We have noticed your blog post on Exadata covering a description for Active Data Guard. It refers to ADG being the “preferred way of Active-Active Oracle replication”.
I’d like to request correction on this comment as ADG does not have bidirectional replication capabilities which is required for Active-Active replication. GoldenGate is a complementary product to Active Data Guard with its bidirectional replication capabilities (as well as heterogeneous database support) and it is the preferred solution for Active-Active database replication.
Please note also a correction on product name spelling, notwithstanding that at least one Oracle person read the post before that, requested a different change, but didn’t notice that error.
