Kellyn Pot’vin-Gorman’s worlds continue to collide:
So, as most people know, I’m not a big fan of Oracle RAC, (Real Application Cluster). My opinion was that it was often sold for use cases that it doesn’t serve, (such as HA) and the resource demands between the nodes, as well as what happens when a node is evicted to those that are left are not in the best interest for most use cases. On the other hand, I LOVE Oracle Data Guard, active or standard, don’t matter, the product is great and it’s an awesome option for those migrating their Oracle databases to Azure VMs.
Read on to see what Oracle Data Guard is and where you might use it.
