Oracle
EBS Lift & Shift Phases
· Phase
I: Back up your on premises Oracle E-Business Suite environment to Oracle Cloud
Infrastructure Object Storage Classic.
· Phase
II: Provision your desired topology on Oracle Cloud Infrastructure Classic,
restoring your application tier to Compute Classic and your database tier to
either Compute Classic, Oracle Database Cloud Service (DBCS), or Exadata Cloud
Service (Exadata CS).
Pre-requisites
of Oracle EBS Lift & Shift
·
AD-TXK Delta 10
should be applied to the on premises Oracle EBS environment before taking the
backup.
Following minimum cloud services are
required according to the topology chosen for lift & shift.

Deploying and updating EBS Cloud Admin Tool as per the given
documents is very important step to make the EBS lift & shift a success.
Installing the Oracle
E-Business Suite Cloud Backup Module On-Premises
You must install the
Oracle E-Business Suite Cloud Backup Module on an on-premises Linux server with
at least 500 MB of free space and the wget libraries installed. The on-premises
Linux server can be one of the Oracle E-Business Suite nodes or another server
that resides in your intranet. This server will be referred to as the backup
module server for the remainder of this tutorial.
1.
Download
Patch 26725016 from My Oracle Support to
the backup module server.
2.
Using
the commands below, change to the directory where you downloaded the patch file
and extract the downloaded patch.
$ cd <download folder>
$ unzip p26725016_R12_Generic.zip
Unzipping the patch
zip file creates a directory named RemoteClone.
3.
Change
to the RemoteClone directory
and change the permission to “execute” for all the downloaded scripts.
$ cd RemoteClone
$ chmod +x *.pl
$ chmod +x lib/*.sh
Backing Up the Environment
Using the Oracle E-Business Suite Cloud Backup Module
The Oracle E-Business
Suite Cloud Backup Module, EBSCloudBackup.pl,
is used to back up your Oracle E-Business Suite environment to Object Storage
Classic. This module captures all the information and creates the cln.props file.
1.
Change to the RemoteClone directory
on the backup module server if you have not already done so.
2.
Run EBSCloudBackup.pl using the following command:
$ 3pt/perl/bin/perl EBSCloudBackup.pl
3.
On the "Migrate Oracle
E-Business Suite - Options" screen, select option 1 to create the backup
and upload it to Object Storage Classic.
==============================================
Migrate Oracle E-Business Suite - Options
==============================================
Migrate Oracle E-Business Suite - Enter Selection:
1: Create E-Business Suite Backup and Upload to Oracle Cloud Infrastructure Classic
2: Create E-Business Suite Backup and Upload to Oracle Cloud Infrastructure
3: Exit
Enter your choice from above list: 1
Next proceed with rest of the prompts according to the
requirement.
Then object storage will be created with a backup as follows.
Create Oracle E-Business
Suite Environment on Oracle Cloud From Your Backup
After you have backed
up your environment using the Oracle E-Business Suite Cloud Backup Module, you
will use the backup to create a new environment with your desired topology.
1.
To
create an environment from a backup stored on Oracle Cloud Infrastructure
Object Storage Classic, choose "2: Oracle Storage Cloud Service
(OSCS)" as the backup source:
=======================================================================
Create Oracle E-Business Suite Environment from Backup - Choose
Source
=======================================================================
[Ctrl-B: Back, Ctrl-H: Main Menu]
1: Stage Area
2: Oracle Storage Cloud Service (OSCS)
3: Snapshot
4: EBS Snapshot Master
Enter your choice from above list: 2
2.
Next,
enter your cloud credentials, including the cloud service endpoints obtained
when you provisioned your Oracle E-Business Suite instance. The screen will
show default values presented in brackets according to the values entered in
the previous execution of the tool. If you do not enter a different response,
the tool uses the default value.
===================================================================
Provision Oracle E-Business Suite - Enter Oracle Cloud
Credentials
===================================================================
[Ctrl-B: Back, Ctrl-H: Main Menu]
Oracle Compute Cloud Service Endpoint
[https://xxx.compute.us.oraclecloud.com/] :
Oracle Storage Cloud Service Endpoint
[https://xxx.storage.oraclecloud.com/v1/Storage-xxx] :
Oracle Cloud Compute Service Instance ID [mycloudserviceid] :
Oracle Cloud Identity Domain [myclouddomain] :
Oracle Cloud Data Center Code (examples: em1, us2, ap3) [em1] :
Oracle Cloud User Name [john.smith@example.com] :
Oracle Cloud Password : <password>
Enter Oracle DBaaS Cloud Service Endpoint
[https://dbaas.oraclecloud.com/] :
Note: The REST endpoints are used
to identify the location of services at the site level within a datacenter.
These endpoints are required in order to create the security artifacts
associated with Oracle Compute Cloud instances (VMs). If the provisioning VM is
located at a different site from your application tier VM (identified by the
Compute Classic endpoint), you will be prompted to provide the provisioning VM
REST endpoint, as seen below:
Enter Oracle Compute Cloud Service Endpoint for Provisioning VM
:
3.
Next,
specify the backup.
===================
Select OSCS Backup
===================
[Ctrl-B: Back, Ctrl-H: Main Menu]
Available backups in OSCS:
1: TEST1
2: TEST2
3: UAT
Choose backup from above list:
1
Next enter the required details for the restoration of Oracle EBS
to cloud as the topology required.
After successful completion you will get a login URL like
following.
