Welcome to Day 5 of the 100-Day Oracle DBA Challenge.
In this lesson, we dive deep into Oracle Physical Storage Structures — the actual files on disk that make an Oracle database work. Understanding these files is a core skill for every Oracle DBA, especially for backup, recovery, and performance tuning.
In this video, you will learn about:
Oracle Datafiles and how they store database objects
Control Files and why they are critical to database startup and recovery
Redo Log Files and their role in instance recovery
Archived Redo Logs and point-in-time recovery
Parameter Files (PFILE and SPFILE)
Oracle Password File
RMAN Backup Files and recovery scenarios
You will also see real-life DBA scenarios, such as:
Recovering lost control files
Restoring missing datafiles
Handling ORA-01157 “file not found” errors
Managing redo log switches
Migrating and protecting database storage
If you are preparing for Oracle DBA roles, Oracle certification, or transitioning from another database platform, this video is essential.
