Installing Rule Designer

As a rule developer, you work in Rule Designer to create at least the beginnings of a decision service. You define a XOM and set up a vocabulary so that you can author and orchestrate the rules that implement your business logic. You must install an update site for Rule Designer into an existing Eclipse.

About this task

Rule Designer is installed as an update site from the Eclipse Marketplace into an existing Eclipse version 4.7.3a.

Note:

If you install Rule Designer in an Eclipse environment that does not use an English locale:

The Eclipse messages remain in the language of your Eclipse environment.
If Rule Designer provides the verbalizer for the language, you can create rule artifacts in this language. If a verbalizer for this language does not exist, the rule artifacts that you create are in English.
Rule Designer messages appear in the locale if it is supported. Otherwise, they appear in English.
To change the locale so that everything is in English, add the osgi.nl=en_US property to the <Eclipse_InstallDir>/configuration/config.ini file, and then restart Rule Designer.

Procedure

Start Eclipse version 4.7.3a.
Click Help > Eclipse Marketplace.
In the Find field, enter the text ODM and click Go.
Locate the entry IBM Operational Decision Manager for Developers - Rule Designer, and then click Install.

Eclipse calculates the dependencies and requirements.
In the Install dialog, click Confirm.
In the Review Licenses dialog, select I accept the terms of the license agreement, and then click Finish.

The installation might take a couple of minutes to complete. If a security warning about the validity of the software opens, click OK to proceed with the installation.
If you are prompted to restart Eclipse, click Yes.
If not displayed by default, switch to the Rule perspective (Window > Open Perspective > Rule).
Optional: If you have an existing project, then import it into the Rule Designer (File > Import > General > Existing Projects into Workspace) and copy them into the workspace.
To be able to publish to Decision Center in an instance of the ODM for production Helm chart, you must either import the default security certificate or use a replacement. For more information, see Importing a security certificate in Rule Designer.

For more information, see Publishing decision services to Decision Center.

Results

Using this installation of Rule Designer you can do the following:

Write a Java™ XOM that references XOM annotations and the decision engine API. For more information, see Adding annotations to the XOM.
Run and debug decision operations. For more information, see Running and debugging decision operations.

Restriction: You cannot generate a Java client project to execute rulesets through the rule engine API or the Rule Execution Server API.
