The goal of this chapter is to introduce you to the various health check utilities, both new in 12.2 and from previous versions, that can greatly ease management and troubleshooting efforts for HA and DR solutions. This chapter will focus mostly on features that are not necessarily Exadata specific but that can and should be used in Exadata and other engineered environments. The chapter will highlight important and often hidden aspects of the different features and software that can be used for health checks as well as cover a few of the new features available in the 12.2 GI and RDBMS software.
