Summary
In this chapter we have briefly discussed about the new feature of Oracle 11gRx and Active Data Guard and their compatibility with several applications. Then we learned how logical backups work and how to generate ASH reports with the ADG feature.
We also worked on how to prepare a cascade standby database, advanced compressions with Oracle Data Guard, and how to prepare Data Guard in cross-platform environments (ranging from Linux to Windows). In the next chapter we will discuss how to integrate Data Guard with GRID EM, RMAN, and RAC.
