The goal of this chapter is to explain some of the key new features and enhancements in Oracle 12cR1 pertaining to Clusterware and RAC Database technologies. Cloud computing is a key focus of the Oracle 12c database, and “cloud” is what the letter “c” in Oracle 12c stands for. In the first part of this chapter, we will explain two core new features of Oracle Clusterware: Oracle Flex Cluster and Oracle Flex Automatic Storage Management (ASM) . One reason why we put these features in this chapter is that they are very closely related. It would be very difficult to discuss one without mentioning the other; in particular, it is not possible to have Flex Clusters without Flex ASM. The use cases of these two new features are very similar and it is likely that they will be implemented together in real database environments. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
