This view contains descriptions of datafile backups that were taken using the proxy copy functionality. It corresponds to the V$PROXY_DATAFILE
view.
In a proxy copy, the media manager takes over the operations of backing up and restoring data. Each row represents a backup of one database file.
Column | Datatype | Description |
---|---|---|
DB_KEY |
NUMBER |
The primary key for the target database. Use this column to form a join with almost any other catalog view. |
DBINC_KEY |
NUMBER |
The primary key for the incarnation of the target database. Use this column to form a join with RC_DATABASE_INCARNATION . |
DB_NAME |
VARCHAR2(8) |
The DB_NAME of the database incarnation to which this record belongs. |
XDF_KEY |
NUMBER |
The proxy copy primary key in the recovery catalog. If you issue the LIST command while connected to the recovery catalog, this value appears in the KEY column of the output. |
RECID |
NUMBER |
The proxy copy record identifier from V$PROXY_DATAFILE . RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file. |
STAMP |
NUMBER |
The proxy copy stamp from V$PROXY_DATAFILE . RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file. |
TAG |
VARCHAR2(32) |
The tag for the proxy copy. |
FILE# |
NUMBER |
The absolute file number of the datafile that is proxy copied. |
CREATION_CHANGE# |
NUMBER |
The datafile creation SCN. |
RESETLOGS_CHANGE# |
NUMBER |
The SCN of the most recent RESETLOGS in the datafile header. |
RESETLOGS_TIME |
DATE |
The time stamp of the most recent RESETLOGS in the datafile header. |
INCREMENTAL_LEVEL |
NUMBER |
0 if this copy is part of an incremental backup strategy, otherwise NULL . |
CHECKPOINT_CHANGE# |
NUMBER |
Checkpoint SCN when the copy was made. |
CHECKPOINT_TIME |
DATE |
Checkpoint time when the copy was made. |
ABSOLUTE_FUZZY_CHANGE# |
NUMBER |
The highest SCN in any block of the file, if known. Recovery must proceed to at least this SCN for the file to become not fuzzy. |
RECOVERY_FUZZY_CHANGE# |
NUMBER |
The SCN to which recovery must proceed for the file to become not fuzzy. If not NULL , this file must be recovered at least to the specified SCN before the database can be opened with this file. |
RECOVERY_FUZZY_TIME |
DATE |
The time that is associated with the RECOVERY_FUZZY_CHANGE# . |
ONLINE_FUZZY |
VARCHAR2(3) |
YES /NO . If set to YES , this copy was made after an instance failure or OFFLINE IMMEDIATE (or is a copy of a copy which was taken improperly while the database was open). Recovery will need to apply all redo up to the next crash recovery marker to make the file consistent. |
BACKUP_FUZZY |
VARCHAR2(3) |
YES /NO . If set to YES , this is a copy taken using the BEGIN BACKUP /END BACKUP backup method. To make this copy consistent, recovery must apply all redo up to the marker that is placed in the redo stream when the ALTER TABLESPACE END BACKUP statement is issued. |
BLOCKS |
NUMBER |
Size of the datafile copy in blocks (also the size of the datafile when the copy was made). |
BLOCK_SIZE |
NUMBER |
The block size for the copy in bytes. |
DEVICE_TYPE |
VARCHAR2(255) |
The type of sequential media device. |
HANDLE |
VARCHAR2(1024) |
The name or "handle" for the proxy copy. RMAN passes this value to the operating system-dependent layer that identifies the file. |
COMMENTS |
VARCHAR2(255) |
Comments about the proxy copy. |
MEDIA |
VARCHAR2(80) |
A comment that contains further information about the media manager that created this backup. |
MEDIA_POOL |
NUMBER |
The number of the media pool in which the proxy copy is stored. |
START_TIME |
DATE |
The time when proxy copy was initiated. |
COMPLETION_TIME |
DATE |
The time when the proxy copy was completed. |
ELAPSED_SECONDS |
NUMBER |
The duration of the proxy copy. |
STATUS |
VARCHAR2(1) |
The status of the backup set: A (available), U (unavailable), X (expired), or D (deleted). |
KEEP |
VARCHAR2(3) |
Indicates whether this proxy copy has a retention policy different from the value for CONFIGURE RETENTION POLICY (YES or NO ). |
KEEP_UNTIL |
DATE |
If the KEEP UNTIL TIME clause of the BACKUP command was specified, then this column shows the date after which this datafile backup becomes obsolete. If the column is NULL and KEEP OPTIONS is not NULL , the backup never becomes obsolete. |
KEEP_OPTIONS |
VARCHAR2(10) |
The KEEP options specified for this backup. Options can be LOGS (RMAN keeps logs needed to recover this backup), NOLOGS (RMAN does not keep logs needed to recover this backup), or NULL (the backup has no KEEP options and will be obsolete based on retention policy). |
