Summary

We didn’t discuss RMAN much in this chapter, but we laid some important groundwork for future discussions of RMAN that you will find in later chapters. As promised, we covered some essential backup and recovery concepts, such as high availability and backup and recovery planning, that are central to the purpose of RMAN. We then defined several Oracle terms that you need to be familiar with later in this text. We then reviewed the Oracle database architecture and internal operations. We cannot stress enough how important it is to have an understanding of how Oracle works inside when it comes time to actually recover your database in an emergency situation. Finally, we discussed manual backup and recovery operations in Oracle. Contrast these to the same RMAN operations in later chapters, and you will find that RMAN is ultimately an easy solution to backup and recovery of your Oracle database.
