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

https://oracle-base.com/blog/2018/01/03/oracle-database-18c-is-not-an-autonomous-database/
ORACLE DATABASE 18C IS NOT AN
AUTONOMOUS DATABASE
Autonomous Database:
It’s a cloud service that happens to use the Oracle 18c database.
Oracle Database 18c:
It’s not autonomous!

provisioning of high availability configurations elevate your SLAs for
maintenance or unexpected failure scenarios. Provisioning choices
include pre-packaged bundles of Oracle database options for DevOps,
Performance, Security, Analytics and Monitoring. The service comes
with an integrated Oracle Application Express environment providing
even more cloud benefit and simplicity.

OCI Concepts

ORACLE CLOUD INFRASTRUCTURE - OCI
REGIONS AND AVAILABILITY DOMAINS
A region is a localized geographic area, and an availability domain is
one or more data centers located within a region.

REGIONS AND AVAILABILITY DOMAINS
• Regions serve different geographies – provide Disaster Recovery capability
• Availability Domains – provide a High Availability foundation within a region

COMPARTMENTS
When you first start working with Oracle Cloud Infrastructure, you need to think
carefully about how you want to use compartments to organize and isolate your
cloud resources.

DETERMINE THE COMPUTE SHAPE TO
MOVE TO CLOUD

I’m a DBA
DETERMINE COMPUTE SHAPE

I will use the same amount of CPUs
and memory that I have on-premises!

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.

SOME MIGRATION METHODS

https://docs.oracle.com/en/cloud/paas/database-dbaas-cloud/csdbi/considerations-migrating-premises-database-dbcs.html
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
• Oracle Database 12c Release 2
• Oracle Database 18c

• 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 11G IN THE CLOUD

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

• 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 CDB TO
ORACLE DATABASE 12C IN THE CLOUD

• RMAN Cross-Platform Transportable Tablespace Backup Sets
• Unplugging/Plugging (CDB)
• Remote Cloning (non-CDB)
• 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

SOME MIGRATION METHODS

LOAD DATA
Uploading data to the cloud, even using fast public internet connections,
migrating 100 TB of data can take up to 8 months.

• Fast Data Migration → Move 100s of TB of data to Oracle
Cloud Infrastructure in days, instead of weeks or months.
• Simple → Use the UI or the Data Transfer Utility to initiate the data
migration process, copy data to hard drives, and ship them to
Oracle, where we import it.
• Scalable → Whether you want to migrate a few terabytes or a
petabyte, Data Transfer Service can help.
• Affordable → There is no cost to transfer data with Data Transfer
Service.

LOAD DATA / MIGRATION – BACKUP / RESTORE
ORACLE DATABASE CLOUD BACKUP MODULE

• Download the Oracle Database Cloud Backup Module, and upload it to the
/tmp directory of both the source and target database instances.
• Log in as the oracle user, change the directory to /tmp, unzip
opc_installer.zip, and run java -jar opc_install.jar to install the backup
module.
