Managing Database Storage Efficient and proactive management of database storage in an Oracle database is critical to maximum performance and reliability. This course covers the management of database storage in tablespaces and datafiles. This course introduces rollback segments and discusses the methods used to manage them. This course describes how to manage redo logs and control files. Oracle creates redo logs for each instance and records all changes made to the database.
Redo logs apply the appropriate changes to the underlying datafiles in recovery situations.
An instance opens one or more control files that hold important information about the database.
