Create Oracle-Connected Nintex Workflows

Use the CData Cloud Hub to connect to Oracle from Nintex Workflow Cloud and build custom workflows using live Oracle data.

Nintex Workflow Cloud is a cloud-based platform where you can design workflows to automate simple or complex processes using drag-and-drop interactions — without writing any code. When paired with the CData Cloud Hub, you get instant, cloud-to-cloud access to Oracle data for business applications. This article shows how to create a virtual database for Oracle in Cloud Hub and build a simple workflow from Oracle data in Nintex.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Oracle, allowing you to build workflows from live Oracle data in Nintex Workflow Cloud — without replicating the data to a natively supported database. Nintex allows you to access data directly using SQL queries. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc.) directly to Oracle, leveraging server-side processing to quickly return the requested Oracle data.

Create a Virtual MySQL Database for Oracle Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Log into Cloud Hub and click Databases.
  2. Select "Oracle" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Oracle.

    To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

    • Port: The port used to connect to the server hosting the Oracle database.
    • User: The user Id provided for authentication with the Oracle database.
    • Password: The password provided for authentication with the Oracle database.
    • Service Name: The service name of the Oracle database.
  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Oracle data from Nintex.

Connect to Oracle in Nintex

The steps below outline creating a new connection for access to Oracle the CData Cloud Hub from Nintex to create a new Oracle data source.

  1. Log into Nintex Workflow Cloud
  2. In the Connections tab, click "Add new"
  3. Select MySQL as the connector and click "Connect"
  4. In the MySQL connection wizard, set the following properties:
    • Connection Name: name the connection (e.g., CData Cloud Hub Oracle Connection)
    • Username: your Cloud Hub username
    • Password: your Cloud Hub password
    • Database Host: your Cloud Hub MySQL endpoint (e.g., myinstance.cdatacloud.net)
    • Database Name: the virtual Oracle database (e.g., OracleOCI1)
  5. Click "Connect"
  6. Configure the connection permissions and click "Save permissions"

Create a Simple Oracle Workflow

With the connection to the CData Cloud Hub configured, we are ready to build a simple workflow to access Oracle data. Start by clicking the "Create workflow" button.

Configure the Start Event Action

  1. Click the start event task and select the "Form" event
  2. Click "Design form"
  3. Drag a "Text - Long" element onto the Form and click the element to configure it
    • Set "Title" to "Enter SQL query"
    • Set "Required" to true
  4. Drag a "Text - Short" element onto the Form and click the element to configure it
    • Set "Title" to "Enter desired result column"
    • Set "Required" to true

Configure an "Execute a Query" Action

  1. Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
  2. Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
  3. Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
  4. Set "Retrieved column" to a new variable (e.g., "values")

Configure a "Send an Email" Action

  1. Add a "Send an email" action after the "Execute a query" action and click to configure the action
  2. Set the "Recipient email address"
  3. Set the "Subject"
  4. Set the "Message body" to the variable created for the retrieved column

Once you configure the actions, click "Save," name the Workflow, and click "Save" again. You now have a simple workflow that will query Oracle using SQL and send an email with the results.
