Download Retail Banking Object Service

  1. Sign-in to the Quantum Fabric console.
  2. Import the DBPLocalServices app into the On-Premise Fabric Console or the Quantum Fabric Cloud environment.
  3. From the Quantum Fabric console, go to API Management > APIs > Objects.
  4. Search for the RBObjects Object service, and then click the ellipsis (three-dot) on the right of the RBObjects service. The context menu opens.
  5. On the context menu, click Export. The RBObjects (v1.0) zipped file is generated and downloaded.

  2. Import the HoldingsAPI Fabric app into the On-Premise Fabric Console or the Quantum Fabric Cloud environment.

    3. Make sure that RBObjects object service does not exist in your environment when you import the application, otherwise the RBObjects object service is overridden by the object service present in the HoldingsAPI Fabric application. If the RBObjects object service exists, take a backup of the Fabric app that contains the RBObjects service.

  3. From the Quantum Fabric console, go to API Management > APIs > Objects.
  4. Search for the RBObjects Object service, and then click the ellipsis (three-dot) on the right of the RBObjects service. The context menu opens.
  5. On the context menu, click Export. The RBObjects (v1.0) zipped file is generated and downloaded.
  6. Rename the RBObjects (v1.0).zip file to RBObjects.zip.
  7. Copy the file to a directory in your local system.

Merge Template Objects

To merge template objects that include interfaces and mappings to the standard Retail Banking objects, follow these steps.

  1. Create a directory or folder in your local system.
  2. Copy the Quantum Fabric command-line tool jar (mfcli.jar) to the directory.
  3. Start a terminal/command shell from the directory.
  4. Run the following command.
    5. java -jar {path_to_mfcli_jar} merge-service-zip --base-service-package-path {path_to_RBObjects_zip} --template-service-package-path {path_to_template_zip} --output-directory {output_directory}

    Example

    java -jar ./mfcli.jar merge-service-zip --base-service-package-path “D:\\BaseApp\\RBObjects.zip” --template-service-package-path “D:\\HoldingsApp\\RBObjects.zip” --output-directory ./ --output-package-name Merge.zip --override-existing
  5. If the merge is successful, a new file called Merge.zip is created in the specified output directory.

Download ArrangementsAPI Fabric Application

  1. Sign in to the Quantum Fabric console.

    2. Make sure that you have downloaded ArrangementsAPI Fabric Application from the specified location.

  2. Import the ArrangmentsAPI Fabric app to the On-Premise Fabric Console or the Quantum Fabric Cloud environment.

    3. Make sure that the RBObjects object service does not exist in your environment when you import the application, otherwise the RBObjects object service is overridden by the object service present in the HoldingsAPI Fabric application. If the RBObjects object service exists, take a backup of the Fabric application that contains the RBObjects service.

  3. From the Quantum Fabric console, go to API Management > APIs > Objects.
  4. Search for the RBObjects Object service, and then click the ellipsis (three-dot) on the right of the RBObjects service. The context menu opens.
  5. On the context menu, click Export. The RBObjects (v1.0) zipped file is generated and downloaded.
  6. Rename the RBObjects (v1.0).zip file to RBObjects.zip.
  7. Copy the file to a directory in your local system.

Merge Templates Object

To merge the objects (interfaces, mappings, and so on) with the standard Retail Banking objects, follow these steps:

  1. Go to the directory to which you copied mfcli.jar earlier.
  2. Start a terminal/command shell from the directory.
  3. Run the following command.
    4. java -jar {path_to_mfcli_jar} merge-service-zip --base-service-package-path {path_to_Merge_zip} --template-service-package-path {path_to_template_zip} --output-directory {output_directory}

    Example

    java -jar ./mfcli.jar merge-service-zip --base-service-package-path “D:\\MergeApp\\Merge.zip” --template-service-package-path “D:\\ArrangementsApp\\RBObjects.zip” --output-directory ./ --output-package-name MergeMSWithBase.zip --override-existing
  4. If the merge is successful, a new file called MergeMSWithBase.zip is created in the specified output directory.

Unlink Existing RBObjects Service

To unlink the Retail Banking object service called RBObjects from the imported base application, follow these steps

  1. Sign-in to the Quantum Fabric console
  2. From the left menu of the Fabric console, go to Apps, and then select the DBPLocalServices application.
  3. From the Quantum Fabric console, go to Configure Services > Objects.
  4. Search for RBObjects Object service, and then click the ellipsis (three-dot) on the right of the RBObjects service. The context menu opens.
  5. From the context menu. select Unlink.

Import Merged Object Service

To import the merged object service, follow these steps

  1. From the Quantum Fabric console, go to API Management > APIs > Objects.
  2. Click Import Service.
  3. Select the merged zip file that you created earlier.
  4. A pop-up window appears with a warning that several items will be overwritten. Click Import.

Relink Object Service

To relink the imported object service, follow these steps

  1. From the left menu of the Fabric console, go to Apps, and then select the DBPLocalServices app.
  2. Go to Configure Services > Objects, and then select Use Existing.
  3. Search for RbObjects, and then select the checkbox next to the object service.
  4. Click Add.
  5. After successfully adding the service, Fabric displays a success prompt. Click Close.

    6. Similarly, add the HoldingsMicroServicesJSON and ArrangementMicroService Integration services to the Integration tab.

  6. Publish the DBPLocalServices app.

Additional Steps for Holdings Microservice

When you import the Holdings Fabric App to the Quantum Fabric Console, the TransactionsOrchService also gets imported to the console. Go to API Management > APIs > Object to verify if the TransactionsOrchService is present in your environment.

If the service is present, you must add the TransactionsOrchService Orchestration service to the DBPLocalServices Fabric application.

If even after importing the Holdings Fabric app the TransactionsOrchService is not present in your environment, you must create a new orchestration service. To create a new orchestration service, follow these steps

  1. Go to APIManagement > APIs > Orchestration.
  2. Select Add New Service.
  3. Name the service TransactionsOrchServices. The Java code will invoke this service
  4. Click Save and Add Operation.
  5. Name the operation getAccountPendingAndPostedTransactions. The Java code will invoke this operation.
  6. Under Operation Mapping > Available services, search and add the getAccountPendingTransactions and getAccountPostedTransactions services to the Orchestration service.
  7. Click Save Operation.

JSON Web Token (JWT) for Authentication Dependencies

Ensure that the following dependencies for the Account Aggregation Fabric app are in place.

  • For JWT Token Generation, the Account Aggregation Fabric app depends on the dbxdb_backendcertificate_get operation that is part of the dbpRbLocalServicesdb Integration service. The dbpRbLocalServicesdb Integration service is present in the DBPLocalServices Fabric application. In this operation, BACKENDCERTNAME from the MSCertificateConstants class is used as a parameter. By default, the value of the BACKENDCERTNAME parameter is T24.
  • When the user logs in through the DbxUserLogin Session, the customer_id is fetched from the Identity handler.
  • For JWT Token Generation, the Account Aggregation Fabric app depends on the dbxdb_backendcertificate table that is present in the database. The dbxdb_backendcertificate table has an entry for T24 backend certificate.

Add Server Properties

To add the server properties, follow these steps

  1. From the left pane of the Fabric Console, select Environments.
  2. Under the Environment to which the app was published click Server. The Admin Console page opens.
