It can be used to upgrade only single-instance databases running on Oracle Restart.

They are never considered obsolete by RMAN.

They can optionally be written to a fast recovery area (FRA).

All archive logs are retained after an archival backup is taken, until the next archival backup is taken of the same database.

Archive logs are retained if they are necessary to allow the database to be recovered to a consistent state when an archival backup is restored.

The SPFILE is included in the archival backup.

Use of a recovery catalog is always required to support the creation and use of archival backups. G)The ARCHIVAL attribute for a backup overrides the RMAN retention policy.

It includes the Oracle Preinstallation RPM.

From Oracle Database 18c, a single RPM can be used to install only Oracle Database Server for a single instance.

It requires an Unbreakable Linux Network (ULN) subscription.

It performs a software-only Oracle Database installation.

It uses a service configuration script to create a single-instance database as part of the installation.

It analyzes a period of time corresponding to the 12 hours of activity.

It runs automatically after each AWR snapshot.

A DBA can run it manually.

Results are written to the alert log.

It analyzes a period of time corresponding to the last day of activity.

Duplication can be done by having the auxiliary database instance pull backup sets from the target database instance.

A connection to an auxiliary instance is always required.

A subset of the target database can be duplicated.

A new DBID is always created for the duplicated database.

A connection to the recovery catalog instance is always required.

A backup of the target database is always required.

Duplication can be done by having the target database instance push copies to the auxiliary database instance.

Space might be reclaimed proactively before space pressure occurs.

Space is always reclaimed proactively before space pressure occurs.

Space might be reclaimed automatically when the retention period for Flashback logs is lowered.

Space is always reclaimed automatically when the retention period for Flashback logs is lowered.

Space is only reclaimed when there is space pressure in the Fast Recovery Area (FRA).

Two or more PDBs can be duplicated with the same RMAN DUPLICATE command.

All tablespaces belonging to a PDB must be duplicated when duplicating the PDB.

The auxiliary instance is automatically created with ENABLE_PLUGGABLE_DATABASE = TRUE.

A user with SYSDBA or SYSBACKUP must be logged in with RMAN to the PDB to duplicate it.

CDB$ROOT and PDB$SEED are automatically duplicated.

The NOREDO clause must be used if the backups of the database being duplicated were taken when the database was in NOARCHIVELOG mode.

The UNDO TABLESPACE clause is always required when no connection exists to the TARGET instance.

RMAN “pushes” the backups of the database to be duplicated over the network to the auxiliary instance.

The NOREDO clause can be used if the backups of the database being duplicated were taken when the database was in ARCHIVE LOG mode.

RMAN SBT-based backups of the database to be duplicated can be used by the auxiliary instance.

The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is closed.

The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is opened.
