Worked for 7 years in Brazil as an Oracle Developer.
2000 - 2007
Worked for 8 years in Angola as an Oracle DBA
for the Ministry of Finance.
2007 - 2015

ORACLE DATABASE CLOUD
CLOUD 101

CLOUD
Will the Database Cloud ”Kill” the DBA?

CLOUD
My Opinion is NO
The DBA will be more specialized:
- Application DBA
- Architecture DBA
- Performance and Tuning DBA
- Big Data DBA

COMMON USE CASES
• Dev/Test/UAT
• Backup to the Cloud

COMMON USE CASES
• Disaster Recovery to the Cloud

COMMON USE CASES ?
• Business Critical Workloads in the
Cloud

CLOUD 101
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Database as a Service (Dbaas)
Software as a Service (SaaS)

• Oracle Database Cloud Service
• Oracle Database Cloud Service – Bare Metal
• Oracle Database Exadata Cloud Service
• Oracle Database Exadata Cloud Machine
• Oracle Database Exadata Express Cloud Service – Managed
• Oracle Database Schema Cloud Service - Managed

ORACLE DATABASE CLOUD BARE METAL
Dedicated Server
Leverage the full power of a dedicated bare metal
server without any noisy neighbor or
virtualization overhead for your database needs.

ORACLE DATABASE EXADATA CLOUD SERVICE
Oracle Database Exadata Cloud Service provides
full Oracle Databases hosted on Oracle Exadata
Database Machine inside the Oracle Cloud.

ORACLE DATABASE EXADATA CLOUD MACHINE
Exadata Cloud Machine or ExaCM is the cloud-
based Oracle Database subscription service
available on Oracle Exadata, but deployed in the
customer data center behind their firewall.

ORACLE DATABASE EXADATA EXPRESS CLOUD
SERVICE
Delivers a managed Oracle Database 12c Release
2 Enterprise Edition running on Oracle Exadata
engineered systems for small to medium sized
data.
**No SmartScan

ORACLE DATABASE SCHEMA CLOUD SERVICE
The "Schema as a Service" model was the first
DBaaS offering delivered on the Oracle Cloud and
it provides a single schema.

ORACLE DATABASE CLOUD SERVICE
SOFTWARE EDITIONS

https://cloud.oracle.com/

Generating an SSH Key Pair on Windows Using the PuTTYgen Program

Generating an SSH Key Pair on UNIX and UNIX-Like Platforms Using the ssh-keygen Utility

DETERMINE COMPUTE SHAPE

Use Database Consolidation Workbench
**Database Consolidation Workbench requires the
Database Diagnostics pack license.

Ok!
Now we have the definition of CPUs, Memory and Storage
equivalent in the Oracle Cloud.

DATA LOADING INTO THE CLOUD
Basically, it depends on the
Cloud Service that I’m using.

DATA LOADING INTO A DATABASE/EXADATA
CLOUD SERVICE
• SQL*Loader
• Import/export
• Oracle Data Pump Export/Import Utility
• Transportable Tablespaces
• Pluggable Databases (PDBs)
§ Remote Cloning
§ Lift and Shift
• APEX/SQL Developer Data Loaders
• External Tables
• Dataguard
• GoldenGate
• REST Services
• Enterprise Manager (12cR5 or 13c)
• Bulk Data Transfer

CHOOSING A MIGRATION METHOD
1 - Database version of your on-premises database:
• Oracle Database 11g Release 2 version lower than 11.2.0.3
• Oracle Database 11g Release 2 version 11.2.0.3 or higher
• Oracle Database 12c Release 1 version lower than 12.1.0.2
• Oracle Database 12c Release 1 version 12.1.0.2 or higher
2 - For on-premises Oracle Database 12c Release 1 databases, the
architecture of the database:
• Multitenant container database (CDB)
• Non-CDB

3 - Endian format (byte ordering) of your on-premises database’s host
platform
4 - Database character set of your on-premises database and Oracle
Database Cloud Service database
5 - Database version of the Oracle Database Cloud database you are
migrating to:
• Oracle Database 11g Release 2
• Oracle Database 12c Release 1

MIGRATING FROM ORACLE DATABASE 11G TO
ORACLE DATABASE 11G IN THE CLOUD
• Data Pump Conventional Export/Import
• Data Pump Transportable Tablespace
• RMAN Transportable Tablespace with Data Pump
• RMAN CONVERT Transportable Tablespace with
Data Pump

MIGRATING FROM ORACLE DATABASE 11G TO
ORACLE DATABASE 12C IN THE CLOUD
• RMAN CONVERT Transportable Tablespace with
Data Pump
• Data Pump Full Transportable

MIGRATING FROM ORACLE DATABASE 12C CDB
TO ORACLE DATABASE 12C IN THE CLOUD
• RMAN CONVERT Transportable Tablespace with Data Pump
• RMAN Cross-Platform Transportable Tablespace Backup Sets
• Unplugging/Plugging (CDB)
• Remote Cloning (CDB)
• RMAN Cross-Platform Transportable PDB
• SQL Developer and SQL*Loader to Migrate Selected Objects
• SQL Developer and INSERT Statements to Migrate Selected Objects

MIGRATING FROM ORACLE DATABASE 12C NON-CDB
TO ORACLE DATABASE 12C IN THE CLOUD
• RMAN CONVERT Transportable Tablespace with Data Pump
• RMAN Cross-Platform Transportable Tablespace Backup Sets
• Unplugging/Plugging (CDB)
• Remote Cloning (non-CDB)
• SQL Developer and SQL*Loader to Migrate Selected Objects

Downtime?

DATA PUMP CONVENTIONAL EXPORT/IMPORT
You can use this method regardless of the endian format and database character set
of the on-premises database.

On-premises host:
mkdir /u01/app/oracle/admin/orcl/dpdump/for_cloud
sqlplus user/password
CREATE DIRECTORY dp_for_cloud AS '/u01/app/oracle/admin/orcl/dpdump/for_cloud';
expdp user/password SCHEMAS=fsowner DIRECTORY=dp_for_cloud

Database Cloud Service compute node:
mkdir /u01/app/oracle/admin/ORCL/dpdump/from_onprem
On-premises host:
scp –i private_key_file
/u01/app/oracle/admin/orcl/dpdump/for_cloud/expdat.dmp
oracle@IP_address_DBaaS_VM:/u01/app/oracle/admin/ORCL/dpdump/from_onprem
CREATE DIRECTORY dp_from_onprem AS '/u01/app/oracle/admin/ORCL/dpdump/from_onprem';
impdp user/password SCHEMAS=fsowner DIRECTORY=dp_from_onprem

DATA PUMP TRANSPORTABLE TABLESPACE
You can use this method only if the on-premises platform is little endian, and the
database character sets of your on-premises database and Oracle Database Cloud
Service database are compatible.

On-premises host:
ALTER TABLESPACE fsindex READ ONLY;
ALTER TABLESPACE fsdata READ ONLY;
expdp user/password TRANSPORT_TABLESPACES=fsdata,fsindex
TRANSPORT_FULL_CHECK=YES DIRECTORY=dp_for_cloud

On-premises host:
$ scp -i private_key_file /u01/app/oracle/admin/orcl/dpdump/for_cloud/expdat.dmp
$ scp -i private_key_file /u01/app/oracle/oradata/orcl/fsdata01.dbf
oracle@IP_address_DBaaS_VM:/u02/app/oracle/oradata/ORCL
$ scp -i private_key_file /u01/app/oracle/oradata/orcl/fsindex01.dbf
ALTER TABLESPACE fsdata READ WRITE;
ALTER TABLESPACE fsindexREAD WRITE;

TRANSPORT_DATAFILES='/u02/app/oracle/oradata/ORCL/fsdata01.dbf',
'/u02/app/oracle/oradata/ORCL/fsindex01.dbf’
ALTER TABLESPACE fsindex READ WRITE;

DATA PUMP FULL TRANSPORTABLE
You can use this method only if the source database release version is 11.2.0.3 or
later, and the database character sets of your on-premises database and Oracle
Database Cloud Service database are compatible.

On-premises host:
Determine the name(s) of the tablespaces and data files that belong to the user-defined
tablespaces by querying DBA_DATA_FILES and make then read only:
ALTER TABLESPACE users READ ONLY;
expdp system/password FULL=y TRANSPORTABLE=always VERSION=12
DUMPFILE=expdat.dmp DIRECTORY=dp_for_cloud

mkdir /u01/app/oracle/admin/ORCL/dpdump/from_source
On-premises host:
$ scp -i private_key_file /u01/app/oracle/oradata/orcl/fsdata01.dbf
oracle@compute_node_IP_address:/u02/app/oracle/oradata/ORCL/PDB2
$ scp -i private_key_file /u01/app/oracle/oradata/orcl/fsindex01.dbf
$ scp -i private_key_file /u01/app/oracle/oradata/orcl/users01.dbf
ALTER TABLESPACE users READ WRITE;

CREATE DIRECTORY dp_from_source AS '/u01/app/oracle/admin/ORCL/dpdump/from_source';
impdp system@PDB2 FULL=y DIRECTORY=dp_from_source TRANSPORT_DATAFILES=
'/u02/app/oracle/oradata/ORCL/PDB2/fsdata01.dbf',

You have to expose your on-premises database over the internet or have a VPN or
SSH tunneling configured:
CREATE DATABASE LINK clone_link CONNECT TO remote_clone_user

CREATE PLUGGABLE DATABASE pdb1 FROM pdb1@clone_link;
CREATE PLUGGABLE DATABASE pdb2b FROM NON$CDB@clone_link;
