 Ability to Create a Duplicate of an Oracle Database Using DBCA in Silent Mode
 By using DBCA in slient mode you can create a duplicate database by
using command CreateDuplicateDB command
 The following are the prerequisites
 Database must in archive log mode
 If duplicate on remote server then source and destination servers
must have connectivity
For Syntax Refer https://docs.oracle.com/en/database/oracle/oracle-database/19/admin/creating-and-
configuring-an-oracle-database.html#GUID-7F4B1A64-5B08-425A-A62E-854542B3FD4E

14. Database Overall
Automated Installation, Configuration and Patching
 Ability to Relocate a PDB to Another CDB Using DBCA in Silent Mode
 By using DBCA in slient mode you can relocate PDB from a remote
CDB to local CDB using relocatePDB command
 The following are the prerequisites
 The local and remove PDB’s must be in archive log mode
 The local PDB must have CREATE PLUGGABLE DATABASE Privilege
in the local CDB root
 The Remote CDB must be in local undo mode
 The remote PDB must have the CREATE PUGGABLE DATABASE,
SESSION and SYSOPER privileges
 The installed options for both local and remote PDB’s must be
same
For Syntax Referhttps://docs.oracle.com/en/database/oracle/oracle-database/19/admin/creating-
and-configuring-an-oracle-database.html#GUID-8DD80A8A-DDE1-471F-8CBB-013D85CFE28F

15. Database Overall
Automated Installation, Configuration and Patching
 Ability to Create a PDB by Cloning a Remote PDB Using DBCA in Silent Mode
 By using DBCA in slient mode you can now create a PDB by cloning a remote PDB
using createFromRemotePDB parameter of the CreatePluggableDatabase
command
 To Create a PDB by cloning a remote PDB you need to specify following parameters
 -pdbName: Name of the local PDB to create.
 -sourceDB: Database name of the local PDB.
 -remotePDBName: Name of the remote PDB to clone.
 -remoteDBConnString: Database connection string of the remote PDB.

database/19/admin/creating-and-configuring-an-oracle-database.html#GUID-6EDDC43D-9BD6-
4096-8192-7E548B826360

16. Database Overall
Automated Installation, Configuration and Patching
 Simplified Image-Based Oracle Database Client Installation
 From Oracle 19c, Oracle client software is available in image file for download
 User needs to extract the image software into a directory and run the runInstaller
script to start Oracle client installation
$ cd /home/oracle_sw_image/
$ ./runInstaller
 During the client install you will be asked to run a script as root user.
 Root Scripts Automation Support for Oracle Database Installation
 From Oracle 19c, you will have an option to setup up the permissions to run the
root configurations scripts by database installer or wizard or run the script
manually.
 To run root scripts automatically select “Automatically run configuration scripts”
during the installation, but you need to provide one the below
 Use sudo - provide the username and password of the user who is member of
sudoers
 Use root user – provide root user password
 Support for Dry-Run Validation of Oracle Clusterware Upgrade
 From Oracle Grid infrastructure 19c, the gridsetup.sh allows you to perform dry-
run mode upgrade for system readiness check
$/oracle/19.0.0/grid/gridSetup.sh -dryRunForUpgrade

17. Database Overall
AutoUpgrade for Oracle Database
 Oracle Data Pump Ability to Exclude ENCRYPTION Clause on Import
 The OMIT_ENCRYPTION_CLAUSE parameter helps to suppress any
encryption clauses associated with objects using encrypted columns.
 OMIT_ENCRYPTION_CLAUSE is a new transform parameter and provide
values Y or N. By default it is set to N, if you need to suppress encryption
clauses set to Y.
TRANSFORM = OMIT_ENCRYPTION_CLAUSE :Y
 Oracle Data Pump Allows Tablespaces to Stay Read-Only During TTS Import
 This option helps to make import faster but database doesn’t reclaim the
space during the import because the bitmaps cannot be rebuilt.
 The option allows a tablespace data file to be mounted on a two
databases as long as it remains read-only
 The source and target databases must have same daylight saving time
(DST) version
TRANSPORTABLE = KEEP_READ_ONLY

18. Database Overall
AutoUpgrade for Oracle Database
 Oracle Data Pump Support for Resource Usage Limitations
 A new paratmer MAX_DATAPUMP_PARALLEL_PER_JOB helps to control number
of parallel workers that you can use for a data pump job
 This parameter mainly helps in multitenant container database environment over
resource utilization.
 Default: 100, Range: 0 to 250, or Auto: 50% of SESSIONS.
 You can able to modify this parameter using ALTER SYSTEM
MAX_DATAPUMP_PARALLEL_PER_JOB = AUTO
 Oracle Data Pump Test Mode for Transportable Tablespaces
 The Test mode option helps to determine how much time an export takes
 TTS_CLOSURE_CHECK parameter will be used only for export operation.
TTS_CLOSURE_CHECK parameter supports the following options:
 ON - self-containment closure check be performed
 OFF - No closure check be performed
 FULL - Full bidirectional closure check be performed
 TEST_MODE - Tablespaces are not required to be in read-only mode

19. Database Overall
AutoUpgrade for Oracle Database
 Oracle Data Pump Prevents Inadvertent Use of Protected Roles
 By using ENABLE_SECURE_ROLES PARAMTER you can prevents inadvertent
use of protected roles and default value is “NO”
 Some Oracle roles require authorization and if you need to use those roles
then you must explicitly enable this parameter the value to YES
ENABLE_SECURE_ROLES PARAMTER: YES
 Oracle Data Pump Loads Partitioned Table Data One Operation
 Instead of separate operations for each partition now you can import all
partitions of a table as one operation
 To use this feature use value GROUP_PARTITION_TABLE_DATA with import
DATA_OPTIONS command
 The default behavior is to import each table partition as separate operation
DATA_OPTIONS = GROUP_PARTITION_TABLE_DATA

20. Database Overall
AutoUpgrade for Oracle Database
 Oracle Data Pump Allows Wildcards for Dump File in Object Store
 By allowing wildcards you can import multiple dump files into oracle
Autonomous Database
 The URL-based dump file name can be simplified in the import command
 Use wildcards on object store service and do not use in the bucket-name
component
$ impdp admin/xxxxxx@orcl
directory=data_pump_dir credential=my_db_cred
dumpfile= https://objectstorage.oraclecloud.com/orcl/exp%.dmp"

21. Database Overall
AutoUpgrade for Oracle Database
 Oracle Data Pump Import Supports More Object Store Credentials
 Oracle 19c offers import support for more object sore credentials beyond
DEFAULT_CREDENTIAL
 A New CREDENTIAL parameter allows support for more object store
credentials for Oracle Autonomous Database
 Oracle Cloud Infrastructure (OCI) Object Storage credential created by
using the DBMS_CLOUD.CREATE_CREDENTIAL() procedure
 The default value is None
$ impdp admin/xxxxxx@orcl
directory=data_pump_dir
CREDENTIAL=user_accessible_credential
dumpfile= “https://objectstorage.cloud.com/orcl/exp%.dmp"

22. Database Overall
AutoUpgrade for Oracle Database
 Oracle Data Pump Import Supports More Object Store Credentials
 The below example shows how to creates a new user-defined credential
in the Oracle Autonomous Database
SQL> BEGIN
DBMS_CLOUD.CREATE_CREDENTIAL(
credential_name => ‘my_db_cred’,
username => ‘orcluser@cloud.com’,
password => ‘auth token' );
END;
$ impdp admin/xxxxxxx@orcl
directory=data_pump_dir
credential=my_db_cred
dumpfile= “https://objectstorage.cloud.com/orcl/exp%.dmp"
