Foundry Admin Adapter

From V9SP1, a new type of integration connector — Foundry Admin has been introduced in Foundry. The Foundry Admin Adapter allows the use of administrative functions (exposed via secure APIs ) on a Foundry runtime server. This permits external systems to invoke these APIs to read or modify settings on the Foundry server.

Managing and Customizing Rules

The Foundry Admin adapter exposes APIs for managing and customizing rules published to a target runtime server.

  • With the Foundry Admin Adapter, you can invoke the Admin endpoints for rules services and manage the published business rules logic. These operations include getting a list of rulesets published to an environment, fetching rules given a ruleset name, read a base rule and custom rule of a particular rule version, create/update custom rules logic, delete a custom rule, and get status of custom rules update/delete actions.

  • With the Foundry Admin Adapter, a Business administration app (for example, Spotlight) can access and manage business rules of an Online banking client app. This is to ensure that external clients get the flexibility of customizing its Business Rules without having to change the application or publish the Foundry app again and again.

  • For this, the Online banking app should expose the Rules management APIs via the Foundry Admin Adapter. The Spotlight Foundry app should talk to these Rules management APIs (as part of Foundry Admin Adapter) through a JSON integration service.

Use Case: Modifying base rules logic dynamically on the run-time server by using a client, for example, Customer 360 (Spotlight)

Consider the following examples:

  • Banks might want to from time-to-time review and update the eligibility criteria for a particular banking product.
  • Based on a customer segment, Bank might want to offer some pre-approved credit card products.
  • During festive seasons, Banks might want to run promotional campaigns for Car Loans and so modify the Business rules to arrive at qualifying customers.

In all of these scenarios, it is noticed that the Business Rules need to be updated by a Bank Manager or Bank Employee through Customer 360 (Spotlight). In order to facilitate this, Rules in Foundry provides the option to update the Rule logic (the MVEL logic a developer configured while developing the App), while retaining the Input and Output parameters that the Rule accepts. This way, a consumer banking app like Online banking or Loans/ Mortgage could get the flexibility of customizing its Rule logic without having to change the application or publish the Foundry app again and again. And by updating and customizing the Rule logic through a Business admin app like Customer 360 (Spotlight), Banks can be guaranteed that only a Bank Manager persona is able to update the Rule logic and no one else without the requisite authority can change those business rules.

Prerequisites

  • A Foundry app should contain a rules set configured using the Rules Service and the app should be published to an environment. For more information on Rules, refer to Rules as a Service.

  • A Foundry app should contain a Foundry Admin integration service and the app should be published to the same environment where you have published your rules services.

    Important: The Rules service and the Admin adapter integration services can be in the same app or separate apps. If these services are created in separate apps, these two apps should be published in the same environment.

    Note: Since the Foundry Admin adapter exposes the Administrative functions on the runtime server, only an authorized user should be able to access them. Hence only the Authenticated App User and Private security levels are supported. Anonymous and Public security levels are not supported for the operations exposed in this adapter.

Perform the following steps to Invoke the Rules Admin APIs using the Foundry Admin Adapter

Step1: Configure a Rules Service and publish it to an environment

  1. Create a Foundry app containing a rules set of a Rules Service.
    For more in formation on Rules, refer to Rules as a Service.
  2. Publish the app to an environment, for example, A.

Step2: Configure an Integration Service using the Foundry Admin adapter

Note: The Foundry Admin adapter integration service can be configured in the same Foundry App that you created in Step1. Or it can be in a different app.

To configure the Foundry Admin Adapter in the Integration service definition tab, follow these steps:

  1. In the Name field, provide a unique name for your service.

  2. From the Service Type list, select Foundry Admin.

  3. In the Authentication section, the Use Existing Identity Provider list displays the existing Identity services available in the Volt MX Foundry App. Select an Identity Service from the list. This will add a security layer onto your Foundry Admin service. If you select an Identity Service, you must provide appropriate login details to invoke the Admin APIs from the client app.

  4. The Advanced section contains the following additional configurations. You can configure them if required:

    Field Description
    Custom Code Custom Code enables you to specify dependent JAR. To specify dependent JAR, select the JAR containing preprocessor or postprocessor libraries from the drop-down list, or click Upload New to browse the JAR file from your local system. This step allows you to further filter the data sent to the back end.

    Important: Make sure that you upload a custom JAR file that is built on the same JDK version used for installing Volt MX Foundry Integration.For example, if the JDK version on the machine where Volt MX Foundry Integration is installed is 1.6, you must use the same JDK version to build your custom jar files. If the JDK version is different, an unsupported class version error will appear when a service is used from a device.
    Throttling API throttling enables you to limit the number of request calls within a minute. If an API exceeds the throttling limit, it will not return the service response.

    To specify throttling in Volt MX Foundry Console, follow these steps:

    In the Total Rate Limit text box, enter a required value. With this value, you can limit the number of requests configured in your Volt MX Foundry console in terms of Total Rate Limit.

    In the Rate Limit Per IP text box, enter a required value. With this value, you can limit the number of IP address requests configured in your Volt MX Foundry console in terms of Per IP Rate Limit.

    To override throttling in App Services Console, refer to Override API Throttling Configuration.

    Note: Enable API throttling in a clustered environment by configuring the VOLTMX_SERVER_NUMBER_OF_NODES property in the server_configuration table available in Admin database. This property indicates the number of nodes configured in the cluster. The default value is 1.

    Note: All options in the Advanced section are optional.

  5. In the Description field, provide a suitable description for the service.

  6. Click Save or Save and Add Operation to save your service definition.

Step3: Configure the Operations for Managing the Rules

  1. Click Save and Add Operation in your service definition page to save your service definition and display the New Operation tab for adding operations.
    OR
    Click Add Operation to add a new operation or from the tree in the left pane, click Add > Add New Operation.
