Oracle vs. SQL Server

As I have seen the benefit for having a post on Oracle database vs. SQL Server architecture, let’s move onto the next frontier- High Availability…or what people think is high availability architecture in the two platforms.

To RAC or Not to RAC

There is a constant rumble among Oracle DBAs- either all-in for Oracle Real Application Cluster, (RAC) or a desire to use it for the tool it was technically intended for. Oracle RAC can be very enticing- complex and feature rich, its the standard for engineered systems, such as Oracle Exadata and even the Oracle Data Appliance, (ODA). Newer implementation features, such as Oracle RAC One-Node offered even greater flexibility in the design of Oracle environments, but we need to also discuss what it isn’t- Oracle RAC is not a Disaster Recovery solution.
