Use CData Sync for automated, continuous, customizable MongoDB replication to Oracle.

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live MongoDB data into your Oracle instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

About MongoDB Data Integration

Accessing and integrating live data from MongoDB has never been easier with CData. Customers rely on CData connectivity to:

MongoDB's flexibility means that it can be used as a transactional, operational, or analytical database. That means CData customers use our solutions to integrate their business data with MongoDB or integrate their MongoDB data with their data warehouse (or both). Customers also leverage our live connectivity options to analyze and report on MongoDB directly from their preferred tools, like Power BI and Tableau.

Getting Started


Configure Oracle as a Replication Destination

Using CData Sync, you can replicate MongoDB data to Oracle. To add a replication destination, navigate to the Connections tab.

  1. Click Add Connection. 👁 Add a new connection.
  2. Select the Destinations tab and locate the Oracle connector. 👁 Configure a Destination connection to Oracle.
  3. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the Oracle connector. For more information about installing new connectors, see Connections in the Help documentation.
  4. To connect to Oracle, set the following connection properties:
    • Connection Name: Enter a connection name of your choice for the Oracle connection.
    • Connection Type: Select a connection type. The connection types available in CData Sync are SID, Service Name, and Data Source.
    • Server: Enter the host name or IP of the server hosting the Oracle database.
    • Port: Enter the port used to connect to the server hosting the Oracle database.
    • User: Enter the user ID provided for authentication with the Oracle database.
    • Password: Enter the password provided for authentication with the Oracle database.
    • SID: Enter the service name of the Oracle database.
    5. 👁 Enter the connection details.
  5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to Oracle and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

👁 Add a label.

In this article, we will demonstrate how to load MongoDB data into Oracle and utilize it as a destination.

Configure the MongoDB Connection

You can configure a connection to MongoDB from the Connections tab. To add a connection to your MongoDB account, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select a source (MongoDB).
  3. Configure the connection properties.

    Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

  4. Click Connect to MongoDB to ensure that the connection is configured properly.
  5. Click Save & Test to save the changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

👁 Select Source and Destination connections for the replication.

Replicate Entire Tables

To replicate an entire table, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of MongoDB tables you wish to replicate into Oracle, and click Add Tasks again.

👁 Choose entire tables to replicate (Salesforce is shown).

Customize Your Replication

You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication with the help of SQL queries. 👁 Configure a replication Transform.

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at specified intervals, ranging from once every 10 minutes to once every month.

👁 Schedule your job to run automatically.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your MongoDB data to Oracle.

Run the Replication Job

Once all the required configurations are made for the job, select the MongoDB table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.

👁 Run the job.
