Flashback logs are written sequentially, and are archived.
Flashback Database uses a restored control file to recover a database.
The Oracle database automatically creates, deletes, and resides flashback logs
In the Fast Recovery Area.
Flashback Database can recover a database to the state that it was in before a
Reset logs operation.
Repository (AWR)?
All AWR tables belong to the SYSTEM schema.
The AWR data is stored in memory and in the database.
The snapshots collected by AWR are used by the self-tuning components in the database
AWR computes time model statistics based on time usage for activities, which
Are displayed in t he v$SYS time model and V$SESS_TIME_MODEL views.
For transparent data encryption?
Individual pluggable databases (PDB plans) in a multitenant container
Database (CDB)?
Tables or table partitions from an RMAN backup?
Assistant (DBCA)?
A backup set may be duplexed with both copies written to disk.
An image copy on disk can be copied to disk.
A backup set may be duplexed with both copies written to sbt.
A backup set may be duplexed so that one copy is written to sbt and the other
To disk.
(TDE)?
Catalog with a pluggable database (PDB) target connection in Oracle
Database 19c and later releases?
The base catalog owner must give the Virtual Private Catalog access to
Metadata for one or more PDBs.
The target PDB must be registered in both the base catalog and the Virtual Private Catalog.
The base catalog must be used by RMAN when performing point-in-time
Recovery for the PDB registered in the Virtual Private Catalog.
The base catalog must be enabled for Virtual Private Catalog use.
Feature?
They are installed via OPatch or OPatchAuto.
A base release is not needed to install patchsets.
They can be applied in a rolling fashion for Clusterware and the databases.
Installing a patchset is considered an "upgrade."
They can introduce new features.
They are only released quarterly.
Multitenant environment?
) It is used in both clustered and non-clustered environments.
) You can add and remove components from an Oracle Restart configuration
With Server Control (SRVCTL) commands.
) It runs from the Oracle Grid Infrastructure home.
) If you shut down a database instance with SQL*Plus, Oracle Restart interprets
