Cloning

Cloning is the process used to create a copy of existing Oracle Fusion Applications;
for example, for creating a test or development environment from the production sys-
tem. This process involves creating a master image of the source environment, copy-
ing into the target environment, and rewiring the target environment. The cloning pro-
cess introduces a new terminology, abstract hostnames, which is basically the source
environment hostnames that are present in the file system structure, MDS, and Oracle
Fusion Applications configuration files. As part of the cloning process, you would not
able to modify abstract hostnames on the target environment. The cloning process
only allows you to modify external hostnames that are used by users to access the
environment.

Before proceeding with cloning, please consider the following key points:

• Make sure your source environment version supports cloning.

• Review release notes and Oracle Support Note#1523300. 1 for the list of

patches that need to be applied to the source environment.

• Make sure the target environment's operating system and storage configura-

tion are similar to the source environment's.

• Make sure the list of ports used in the source environment is available in the

target environment.

• The number of hosts on a target environment should be the same as the

source environment's hosts. You can downgrade hardware compared to the
source environment if required, but make sure the hardware is configured suf-
ficiently to support the target user base.

• Install JDK on the target environment before extracting source files

• Abstract names / internal hostnames should not be placed in the DNS; these

entries should be part of the /etc/hosts file.

The following are the high-level steps that need to be performed to create the test en-
vironment from production:

• Collect all the relevant information that you have supplied during the provision-

ing of Oracle Fusion Applications, such as host details, web tier configuration,
ports, topology, domain configuration, database details, and IDM configura-
tion details. The Oracle document provides links to the Discovery Workbook ,
