List Backup Of Controlfile Autobackup
Oracle database controlfiles can be automatically backed up by the LIST BACKUP OF CONTROLLFILE command.
This command can be used to create a backup of the controlfile in a user-specified directory.
The controlfile autobackup feature can be used to quickly create a backup of the controlfile in the event of a database failure.
The controlfile autobackup feature can also be used to create a backup of the controlfile before making changes to the controlfile.

How do I list all backups in RMAN?
Oracle Database provides a powerful command-line tool, called RMAN ( Recovery Manager ), for managing backup and recovery operations. RMAN can be used to create backups, restore files, and recover data.
One of the most common tasks that you will likely need to do with RMAN is to list all of the backups that are stored in your backup archive. This can be easily done by running the LIST BACKUP command.
The LIST BACKUP command will display a list of all backups that are stored in your backup archive, including the name of the backup, the date and time that the backup was created, and the size of the backup.
You can also use the LIST BACKUP command to filter the results by specifying a date range, backup type, or backup set name.
Here is an example of the output from the LIST BACKUP command:
LIST BACKUP
List of backups
====================
File Size(MB) Date Time Type
——- —- ——– —————–
25600 07-APR-2018 08:05:14 FULL
21392 07-APR-2018 07:57:48 INCREMENTAL_1
21392 07-APR-2018 07:57:48 INCREMENTAL_2
21392 07-APR-2018 07:57:48 INCREMENTAL_3
You can also use the LIST BACKUP command to print the contents of a specific backup set. For example, if you want to print the contents of the backup set named “MYBACKUP”, you would use the following command:
LIST BACKUP OF MYBACKUP
The output of this command will show you the name of the backup set, the date and time that the backup was created, and the size of the backup.
How do I find my Controlfile Autobackup?
If you are using the Control Panel autobackup feature, your Controlfile Autobackup is located in the Autobackup folder in your Documents folder.
What is Controlfile Autobackup in RMAN?
Oracle Database has a number of automatic backup features that you can use to ensure the safety of your data. One of these features is called controlfile autobackup. This feature automatically backs up the control file every time a backup is made.
The control file is a critical component of an Oracle database. It contains information about the database, including the names of the datafiles and the logfiles. If the control file is damaged or lost, you may not be able to start the database.
That’s why it’s important to have a backup of the control file. With controlfile autobackup, you can be sure that you always have a recent copy of the control file. This can help you avoid any potential problems if the control file is damaged or lost.
Which RMAN command takes Controlfile and Spfile backup?
Oracle Database provides a number of commands to backup the Controlfile and Spfile. The following are the most common commands used to back up Controlfiles and Spfiles:
RMAN> BACKUP CURRENT CONTROLFILE TO TRACE
RMAN> BACKUP SPFILE TO TRACE
RMAN> BACKUP CURRENT CONTROLFILE TO DATABASE
RMAN> BACKUP SPFILE TO DATABASE
Each of these commands has its own benefits and drawbacks. The BACKUP CURRENT CONTROLFILE TO TRACE and BACKUP SPFILE TO TRACE commands create backups that are in human-readable format. This makes it easy to view the contents of the backup, but it takes up more space on the disk. The BACKUP CURRENT CONTROLFILE TO DATABASE and BACKUP SPFILE TO DATABASE commands create backups that are in binary format. This takes up less space on the disk, but it is difficult to view the contents of the backup.
How do I view an RMAN backup?
An RMAN backup is a copy of a database that has been created by using the Recovery Manager (RMAN) utility. The backup can be used to restore the database to its previous state in the event of data loss or corruption.
You can view an RMAN backup by opening it in a text editor. The backup will be in a format that is specific to the RMAN utility.
How do I list obsolete backup in RMAN?
When you create a backup with RMAN, the backup enters the RECOVERABLE STATE. A backup remains in the RECOVERABLE STATE until you issue the REBUILD command to convert it to the AVAILABLE state. The AVAILABLE state indicates that the backup is ready to use.
A backup enters the obsolete state when the backup’s files are no longer needed. You can list the obsolete backups by issuing the LIST OBSOLETE command.
The following example shows how to list the obsolete backups:
RMAN> LIST OBSOLETE;

How do I restore a control file?
A control file is a critical part of an Oracle database. It contains information about the database, including the names and locations of the datafiles and redo logfiles. If the control file is lost or damaged, the database will not start.
If you lose or damage your control file, you can restore it from a backup. To do this, you must first identify the control file’s name and location. The control file is usually located in the same directory as the datafiles.
Once you have identified the control file’s name and location, you can restore it using the Recovery Manager (RMAN) utility. RMAN will restore the control file and all of the datafiles and redo logfiles that are associated with it.
If you do not have a backup of your control file, you can create a new control file using the CREATE CONTROLFILE command. This command will create a new control file based on the information in the SYSTEM tablespace.
