The physical structures of the database and the role each plays in the database recovery process determine the forms of backup and recovery available through user-managed techniques and through RMAN. The files and other structures that make up an Oracle database store data and safeguard it against possible failures. This discussion introduces each of the physical structures that make up an Oracle database and their role in the reconstruction of a database from backup. This section contains these topics:. An Oracle database consists of one or more logical storage units called tablespaces. Each tablespace in an Oracle database consists of one or more files called datafiles, physical files under the host operating system which collectively contain the data stored in the tablespace. The simplest Oracle database would have one tablespace, stored in one datafile.

However, some of the most common scenarios for database restore and recovery are presented in full here:. The procedures outlined here will restore the whole database or individual tablespaces to their original locations. You must have the complete set of archived logs and incremental backups needed for media recovery of your available datafile backups. For any datafiles for which you have no backup, you must have a complete set of online and archived redo logs going back to the creation of that datafile. With a complete set of redo logs, RMAN can re-create a datafile for which there is no backup, by creating an empty datafile and then re-applying all changes since the file was created as part of the recovery process. If automatic channels are configured, then RMAN allocates all channels configured for the available device types according to their parallelism settings.

Cold backup can be taken after you shutdown the database, now database is unavailable for database users. Hot backup is active backup, it can be done when the database is running and data is being updated or read by database users. Once put your database in backup mode, Oracle only freezes the datafile headers, but it keep updating the blocks inside the datafile. So their headers are at the same SCN, but the database blocks are not. The database writer DBWR is updating the file. During hot backup, when we are copying a data file meanwhile, the database is writing to the data file by DBWR. Oracle database is also writing to the redo.
