ODI 12.1.3: New Model and Topology Objects Wizard

Oracle Data Integrator 12.1.3 introduces a new wizard to quickly create Models. This wizard will not only help you create your Models more easily, if needed it will also create the entire required infrastructure in the ODI Topology: Data Servers, Physical and Logical Schemas.

In this blog article we will go through an example together and add a new Model to access the HR sample schema of an Oracle database. You can follow through this example using the ODI Getting Started VirtualBox image which is available here: http://www.oracle.com/technetwork/middleware/data-integrator/odi-demo-2032565.html

The ‘New Model and Topology Objects’ wizard can be accessed from the Models menu as shown below:

The wizard opens up and displays default settings. From there we can customize our objects before they actually get created in the ODI repositories.

In this example we want to access tables stored in the HR schema of an Oracle database so we name the Model ORACLE_HR. Note that the Logical Schema as well as the Schema and Work Schema fields in the Physical Schema section automatically default to the Model name:

Next we will give a new name to our Data Server: LINUX_LOCAL_ORACLE since we are connecting to a local Oracle database running on a Linux host.

We then fill in the User, Password and URL fields to reflect the environment we are in. To access the HR schema we use the ODI Staging area user which is ODI_STAGING. This is a best practice and it also ensures that the Work Schema field automatically gets updated with the right value for the Staging Area.

Note that the wizard also allows us to link a new Model to an existing Data Server.

Finally we click on Test Connection to make sure the parameters are correct.


Then we update the Schema field using the drop-down list to point to the HR schema at the database level.

Our Model is now fully set up, we click on OK to have it created along with its related Topology objects. The Model ORACLE_HR opens up allowing us to reverse-engineer the tables using the Selective Reverse-Engineering tab:

We pick all the tables and click on the Reverse Engineer button to start this process and save the Model at the same time. A new Model called ORACLE_HR was created as shown below as well as the appropriate objects in the Topology:
