Configuring the Operational Decision Manager (ODM) stage by using the wizard (DataStage®)

The Operational Decision Manager (ODM) stage includes a wizard that you can use to configure properties and link schemas in the stage to invoke the selected ODM ruleset when the job runs.

About this task

When you configure the stage to invoke a specific ODM ruleset, the number of input links must match the number of IN and IN_OUT ruleset parameters, and the number of output links must match the number of OUT and IN_OUT parameters. Reject links on the stage are excluded from this formula and are ignored by the configuration wizard.

If you know the number and type of ruleset parameters in advance, you can define the correct number of links of correct types on the stage before the wizard is started. If the information is not available, you can still start the wizard and use it to locate the ruleset of interest and find out the number and type of parameters that are defined for it.

However, if links are missing, then you must cancel the wizard and manually add the required links in order for the wizard to be able to complete the stage configuration because the wizard cannot automatically add any links to the stage.

Procedure

  1. Double-click the ODM stage to open the properties panel.
  2. On the Stage tab, then click Configure.
  3. On the Engine mode and ruleset filter page, specify the engine mode and ruleset filter expression, then click Next.
  4. On the Ruleset Parameters selection page, configure the import mode and the ruleset parameters and the corresponding Java™ class methods for which to configure schema definitions for the links defined on the stage. Then, click Next.
  5. On the Schema mapping for inputs and ruleset parameter page, define the associations among the inputs and ruleset parameters of the stage. Then, click Next.
  6. On the Schema mapping for outputs and ruleset parameter page, define the associations among the outputs and ruleset parameters of the stage. Then, click Next.
  7. On the Import ruleset parameters preview page, review the report and the summary of expected results and then click Finish.
