Changes in This Release for Backup and Recovery Reference

This preface contains:

Changes in Oracle Database Release 19c

The following are changes in Oracle Database Backup and Recovery Reference for Oracle Database release 19c.

New Features

  • PLUGGABLE DATABASE clause in GRANT and REVOKE commands

    You can grant and revoke privileges on a specific PDB to a database user. See GRANT and REVOKE.

  • Recovery catalog support for PDBs

    You can connect to the recovery catalog when you are connected to a target PDB.

    See CONNECT.

Deprecated Features

  • Starting in Oracle Database 19c, the Data Recovery Advisor (DRA) feature is deprecated.

    The deprecation of DRA includes deprecation of the following Oracle Recovery Manager (RMAN) commands: LIST FAILURE, ADVISE FAILURE, REPAIR FAILURE, and CHANGE FAILURE. Database administrators will no longer have access to these commands. There is no replacement feature for DRA.

  • The RECOVER…SNAPSHOT TIME method of recovering a database to a point in time using a particular snapshot is deprecated in Oracle Database 19c.

    Instead of RECOVER…SNAPSHOT TIME, Oracle recommends that you use ALTER DATABASE BEGIN/END BACKUP before and after creating the storage snapshot of the data files and then use RECOVER .. UNTIL TIME to a specific timestamp or system change number (SCN) after the END BACKUP completion time. Oracle recommends that ALTER DATABASE BEGIN/END BACKUP always be used when performing snapshots on a running database to ensure data recovery integrity. Archived log redo logs must be separately backed up and restored for recovery operations.

    See Recovery Using Storage Snapshot Optimization in the Backup and Recovery User's Guide for detailed examples.
