5.16 RC_BACKUP_PIECE_DETAILS

RC_BACKUP_PIECE_DETAILS contains detailed information about all available backup pieces recorded in the recovery catalog.

The semantics of most columns duplicate the RC_BACKUP_PIECE recovery catalog view. This view is primarily intended to be used internally by Enterprise Manager.

Column Data Type Description

SESSION_KEY

NUMBER

Session identifier. Use in joins with RC_RMAN_OUTPUT and RC_RMAN_BACKUP_JOB_DETAILS.

SESSION_RECID

NUMBER

With SESSION_STAMP, uniquely identifies output for this backup job from RC_RMAN_OUTPUT.

SESSION_STAMP

NUMBER

With SESSION_RECID, uniquely identifies output for this backup job from RC_RMAN_OUTPUT.

DB_NAME

VARCHAR2(8)

The DB_NAME of the database incarnation to which this record belongs.

DB_KEY

NUMBER

The primary key for this database in the recovery catalog. Use this column to join with almost any other catalog view.

DB_ID

NUMBER

The DBID of the database incarnation to which this record belongs.

BP_KEY

NUMBER

The primary key for the backup piece in the recovery catalog. If you issue the LIST command while RMAN is connected to the recovery catalog, then this value appears in the KEY column of the output.

RECID

NUMBER

The backup piece RECID from RC_BACKUP_PIECE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.

STAMP

NUMBER

The backup piece stamp propagated from V$BACKUP_PIECE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.

BS_KEY

NUMBER

The primary key of the backup set to which this record belongs in the recovery catalog. Use this column to join with RC_BACKUP_SET or RC_BACKUP_PIECE.

SET_STAMP

NUMBER

The SET_STAMP value from V$BACKUP_SET. SET_STAMP and SET_COUNT form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file.

SET_COUNT

NUMBER

The SET_COUNT value from V$BACKUP_SET. SET_STAMP and SET_COUNT form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file.

The time when the backup piece was completed.

ELAPSED_SECONDS

NUMBER

The duration of the creation of the backup piece.

STATUS

Oracle Secure Backup (OSB) 19.1 desupport was announced on May 1, 2026 with premier support end date on September 30, 2027. See My Oracle Support note PNEWS3035 for more information. Please refer to Lifetime Support Policy: Oracle Technology Products for updated support timeframes.

Oracle recommends that database backups to cloud take advantage of Oracle Database Zero Data Loss Cloud Protect, which uses Oracle Zero Data Loss Autonomous Recovery Service in OCI. Cloud Protect offers an efficient incremental forever backup strategy, real-time transaction protection, logically air-gapped immutable backups, and fast, point-in-time recovery.

For customers who require database backups to Amazon S3, Oracle Database Cloud Backup for Amazon S3 may be used. This offering is similar to Oracle Secure Backup Cloud Module in that it is fully integrated with Recovery Manager (RMAN) and enables you to back up your Oracle database to Amazon S3. You can exchange your Oracle Secure Backup license for an Oracle Database Cloud Backup for Amazon S3 license on a 1:1 basis. See Oracle Database Cloud Backup for Amazon S3 for more information.

PIECES_PER_SET

NUMBER

Number of backup pieces in the backup set containing this backup piece.

SIZE_BYTES_DISPLAY

VARCHAR2(32K)

Same value as BYTES, but converted to a user-displayable format, for example, 798.01M or 5.25G.
