OIC - How to Avoid Storing Duplicate Data in a Database When Integrating ERP with Oracle Integration Cloud (OIC)

To avoid storing duplicate data when integrating ERP data into a database using Oracle Integration Cloud (OIC), follow these steps:

1. Use Unique Identifiers: Ensure the ERP data contains a unique identifier (e.g., invoice number or order ID).

2. Check for Existing Records: Before inserting data into the database, query the table to check if a record with the same identifier already exists. Use SQL like:

SELECT COUNT(*) FROM table WHERE identifier = :identifier

3. Conditional Insert/Update:

if no record exists, insert the new data.

If a record exists, skip the insert or update the existing record using an upsert (merge) operation.

4. Data Mapping: Use OIC’s data mapping to filter out duplicates before inserting data.

5. Transaction Management: Handle database transactions and retries to ensure consistency and avoid duplicate inserts.

This approach ensures that only unique records are inserted, preventing data duplication in the database.


OIC - Handling Null or Empty BIP Report Files in Oracle Integration Cloud to Prevent Flow to Downstream Applications

To handle empty files or files with headers but no data in Oracle Integration Cloud (OIC), follow these steps:

1. Handling Empty Files (Size = 0):

Check File Size: After invoking the BIP report, check if the file size is zero. If the file size is zero, it means the file is empty.

Action: If the file is empty (size = 0), throw a fault to prevent processing or send a notification to alert stakeholders that the file is empty.

2. Handling Files with Header but No Data:

Check File Content: If the file contains a header but no actual data rows (i.e., only the header is present), you need to read the file content.

Action: Parse the file to count the number of rows (excluding the header). If the row count is less than 2 (meaning only the header is present), throw a fault or apply a skip condition to prevent further processing.

By implementing these steps, you ensure that only valid files with data are processed, and empty or incomplete files are handled appropriately to avoid unnecessary downstream processing.


OIC - Enrichment Service in Oracle Integration Cloud (OIC)

Enrichment Service in Oracle Integration Cloud (OIC)

The Enrichment Service in Oracle Integration Cloud (OIC) allows you to enhance the data being processed within your integrations by adding additional information from external systems or by transforming the data in meaningful ways. This is typically used to improve the quality or completeness of the data as it flows between systems.

Use Cases for Enrichment Service

  1. Data Augmentation: Add additional information from external data sources (e.g., CRM, ERP, or third-party APIs) to enrich the business data in your integrations. For example, enriching customer records with the latest social media data or financial details.
  2. Lookups and Data Transformation: Use enrichment to perform lookups (e.g., get product details based on a product ID) or to transform the format of the data (e.g., convert currencies, calculate discounts).
  3. Enhance Business Processes: Streamline business processes by ensuring that each data record is as complete and accurate as possible before it's passed on to downstream systems.

How to Configure Enrichment in OIC

  1. Create Integration: In the OIC console, create a new integration or modify an existing integration to include the enrichment logic.
  2. Add Enrichment Stage: In the integration flow, add an Enrichment stage.
  3. Lookup: Use lookups to pull additional data from sources like databases, RESTful APIs, or SOAP web services.
  4. Data Transformation: Use mapping functions to transform or enrich the incoming data. For example, you might use a mapping function to combine customer details with product data.
  5. Define Data Sources: Define the external data sources or services from which the enrichment data will be fetched (like Oracle Cloud Services, on-prem systems, or third-party APIs).
  6. Use Enriched Data: Once the data is enriched, it can be used in subsequent steps in the integration process (e.g., sending enriched data to an external system, updating records in the source system).

Example of Enrichment Service in Action

  1. Customer Data Enrichment: A company integrates OIC with a third-party address verification service to enhance customer addresses. The integration retrieves the correct address format (street name, postal code) from the external service and uses this data to update the CRM system.
  2. Currency Conversion: In a global e-commerce integration, OIC could use an enrichment service to fetch real-time currency exchange rates and apply the correct conversion to customer orders, ensuring accurate pricing in different currencies.

Benefits of Using Enrichment Service

  1. Improved Data Quality: Ensure that the data used in downstream processes is complete and accurate.
  2. Automation: Reduce manual work by automating data augmentation from external sources.
  3. Faster Decision Making: With enriched and real-time data, businesses can make more informed decisions.
  4. Cost Efficiency: Prevent errors or rework that might arise from incomplete or outdated data.


OIC - Resubmit Failed Messages

Resubmit Failed Messages

We can manually resubmit failed messages. If a local scope has been defined in the integration, resubmission starts at the local scope level. Otherwise, resubmission starts from the beginning of the integration. Oracle Integration does not automatically resubmit failed messages.

All faulted instances in asynchronous flows in Oracle Integration are recoverable and can be resubmitted. Synchronous flows cannot be resubmitted. You can resubmit errors in the following ways:
  • Single failed message resubmissions

  • Bulk failed message resubmissions

Error instances that are resubmitted and successfully resolved are removed from the error list. If an instance is resubmitted and is in progress, a state of In Progress is displayed in the list. During this state, additional resubmits of this error instance are not permitted.

To resubmit failed messages:

  1. In the left navigation pane, click Home > Monitoring > Integrations > Errors.

  2. From the Filters icon link, select the time period or retention period during which to search for integration errors.


    Description of errors_page.png follows


  3. Resubmit errors in either of two ways:

    1. Select the check boxes of errors to resubmit together.

    2. Click Resubmit in the upper right corner.

    or

    1. Go to the row of the specific error to resubmit.

    2. Click Resubmit icon.

    A message is displayed at the top of the page:

OIC - Versioning in Oracle Integration Cloud (OIC) - Generation 3

Versioning in Oracle Integration Cloud (OIC) - Generation 3

In OIC Generation 3, versioning follows a three-part format:

1. Major Version:

Indicates significant changes or new functionality that may introduce breaking changes.

Example: Moving from 01.x.x to 02.x.x.

Two major versions can be active simultaneously, allowing phased rollouts or parallel use.

 2. Minor Version:

Represents backward-compatible updates or new features.

Example: Moving from 01.00.x to 01.01.x.

Only one minor version can be active at a time within a major version.

3. Patch Version:

Used for small fixes or non-breaking changes.

Example: Moving from 01.00.0000 to 01.00.0001.

Only one patch version can be active at a time within a minor version.

Key Features

Multiple Active Versions: Two major versions can be active simultaneously, but only one minor or patch version is allowed per major version.

Draft and Active States: Draft versions are used for testing and updates, while active versions are used in production.

Version History: Previous versions are retained for rollback if needed.

Testing and Deployment: Draft versions are isolated for testing without affecting active versions.


This flexible versioning approach ensures seamless updates, backward compatibility, and controlled multi-version management.

OIC - Oracle Integration-Bulk load into Oracle ATP OR Oracle ADW

Oracle Integration enhances its database adapters, including Oracle Autonomous Transaction Processing (ATP) and Autonomous Data Warehouse (ADW) Adapters, to support native bulk load operations. Leveraging Oracle Autonomous database and OCI features, these enhancements significantly boost performance.

A typical use case involves importing bulk data by retrieving a file (e.g., from an FTP server or HCM system), placing it in object storage, and loading its contents into an ATP-S database. Oracle Integration can also reformat files (e.g., XML or JSON) into the database's required format, such as CSV.

To implement the integration flow:

  1. Create an App Driven Orchestration or Schedule Based Orchestration based on the requirement.
  2. Download the file from the FTP location to the staging area.
  3. Use the Oracle Autonomous Transaction Processing Adapter or Autonomous Data Warehouse Adapter as per your database instance.
  4. In the adapter wizard:
    1. Select Perform bulk data import operation.
    2. Choose the OCI Bucket and enable Delete file from object storage after operation completion.
    3. Edit Copy data format options, select the file format, schema, table, and columns. Ensure the columns align with the incoming data order.
