The LIST command uses the information in the RMAN repository to provide lists of backups, archived logs, and database incarnations. You can use the output of LIST to identify specific backups you wish to use with other RMAN commands.
This section contains these topics:
You can control how the output is displayed by using the BY BACKUP and BY FILE options of the LIST command and choosing between the SUMMARY and VERBOSE options.
The primary purpose of the LIST command is to determine which backups are available. For example, you can list:
Backups and proxy copies of a database, tablespace, datafile, archived redo log, or control file
Backups that have expired
Backups restricted by time, path name, device type, tag, or recoverability
Incarnations of a database
Note that the V$BACKUP_FILES also contains list information for backups.
By default, RMAN lists backups by backup, which means that it serially lists each backup or proxy copy and then identifies the files included in the backup. You can also list backups by file.
By default, RMAN lists in verbose mode. You can also list backups in a summary mode if the verbose mode generates too much output.
To list backups by backup, connect to the target database and recovery catalog (if you use one), and then execute the LIST BACKUP command. Specify the desired objects with the listObjList clause. For example, you can enter:
LIST BACKUP; # lists backup sets, image copies, and proxy copies LIST BACKUPSET; # lists only backup sets and proxy copies LIST COPY; # lists only disk copies
Optionally, specify EXPIRED to identify backups not found during a crosscheck:
LIST EXPIRED BACKUP;
Examine the output (refer to Oracle Database Backup and Recovery Reference for an explanation of the various column headings in the LIST output). Sample output of LIST BACKUP follows:

Specify the desired objects with the listObjList or recordSpec clause (refer to Oracle Database Backup and Recovery Reference). If you do not specify an object, then RMAN displays copies of all database files and archived logs. By default, RMAN lists in verbose mode, which means that it provides extensive, multiline information.
To list backups by file, connect the RMAN client to the target database and recovery catalog (if you use one), and then execute LIST with the BY FILE option, specifying the desired objects to list and options.For example, you can enter:
LIST BACKUP BY FILE; # shows backup sets, proxy copies, and image copies LIST COPY BY FILE; # shows only disk copies
For another example, you could specify the EXPIRED option to identify backups not found during a crosscheck:
LIST EXPIRED BACKUP BY FILE;

By default the LIST output is detailed, but you can also specify that RMAN display the output in summarized form. Specify the desired objects with the listObjectList or recordSpec clause. If you do not specify an object, then LIST BACKUP displays all backups.
After connecting to the target database and recovery catalog (if you use one), execute LIST BACKUP, specifying the desired objects and options. For example:
LIST BACKUP SUMMARY; # lists backup sets, proxy copies, and disk copies
You can also specify the EXPIRED keyword to identify those backups that were not found during a crosscheck:
LIST EXPIRED BACKUP SUMMARY;

Refer to Oracle Database Backup and Recovery Reference for an explanation of the various column headings in the LIST output.
You can specify several different conditions to narrow your LIST output.
After connecting to the target database and recovery catalog (if you use one), execute LIST COPY or LIST BACKUP with the listObjList or recordSpec clause. For example, enter any of the following commands:
# lists backups of all files in database LIST BACKUP OF DATABASE; # lists copy of specified datafile LIST COPY OF DATAFILE 'ora_home/oradata/trgt/system01.dbf'; # lists specified backup set LIST BACKUPSET 213; # lists datafile copy LIST DATAFILECOPY '/tmp/tools01.dbf';
You can also restrict the search by specifying the maintQualifier or RECOVERABLE clause. For example, enter:
# specify a backup set by tag LIST BACKUPSET TAG 'weekly_full_db_backup'; # specify a backup or copy by device type LIST COPY OF DATAFILE 'ora_home/oradata/trgt/system01.dbf' DEVICE TYPE sbt; # specify a backup by directory or path LIST BACKUP LIKE '/tmp/%'; # specify a backup or copy by a range of completion dates LIST COPY OF DATAFILE 2 COMPLETED BETWEEN '10-DEC-2002' AND '17-DEC-2002'; # specify logs backed up at least twice to tape LIST ARCHIVELOG ALL BACKED UP 2 TIMES TO DEVICE TYPE sbt;
The output depends upon the options you pass to the LIST command. For example, the following lists copies of datafile 1:
RMAN> list backup of datafile 1;

Each time an OPEN RESETLOGS operation is performed on a database, this operation creates a new incarnation of the database. Database incarnations and their effect upon database recovery with RMAN are explained in more detail in Oracle Database Backup and Recovery Advanced User's Guide.
When performing incremental backups, RMAN can use a backup from a previous incarnation or the current incarnation as a basis for subsequent incremental backups. When performing restore and recovery, RMAN can use backups from a previous incarnation in restore and recovery operations just as it would use backups from the current incarnation, as long as all archived logs are available.
Use the LIST INCARNATION command to see the incarnations of your database.
To list database incarnations:
After connecting to the target database and the recovery catalog if applicable, run LIST INCARNATION:
RMAN> LIST INCARNATION;
If you are using a recovery catalog, and if you register multiple target databases in the same catalog, then you can distinguish them by using the OF DATABASE option:
RMAN> LIST INCARNATION OF DATABASE prod3;
Refer to Oracle Database Backup and Recovery Reference for an explanation of the various column headings in the LIST output). Sample output follows:
RMAN> LIST INCARNATION OF DATABASE; List of Database Incarnations DB Key Inc Key DB Name DB ID STATUS Reset SCN Reset Time ------- ------- -------- ---------------- ------ ---------- ---------- 1 1 RDBMS 774627068 PARENT 1 21-OCT-03 2 2 RDBMS 774627068 CURRENT 173832 21-OCT-03
The preceding output indicates that a RESETLOGS was performed on database trgt at SCN 164378, resulting in a new incarnation. The incarnation is distinguished by incarnation key (represented in the Inc Key column).
