Integrate Linear Data in Your Informatica Cloud Instance

Informatica Cloud allows you to perform extract, transform, and load (ETL) tasks in the cloud. With the Cloud Secure Agent and the CData JDBC Driver for Linear, you get live access to Linear data, directly within Informatica Cloud. In this article, we will walk through downloading and registering the Cloud Secure Agent, connecting to Linear through the JDBC Driver and generating a mapping that can be used in any Informatica Cloud process.

Informatica Cloud Secure Agent

To work with the Linear data through the JDBC Driver, install the Cloud Secure Agent.

1. Navigate to the Administrator page in Informatica Cloud
2. Select the Runtime Environments tab
3. Click "Download Secure Agent"
4. Make note of the Install Token
5. Run the installer on the client machine and register the Cloud Secure Agent with your username and install token

NOTE: It may take some time for all of the Cloud Secure Agent services to get up and running.

Connecting to the Linear JDBC Driver

With the Cloud Secure Agent installed and running, you are ready to connect to Linear through the JDBC Driver.

Adding the JDBC Driver to the Secure Agent Machine

1. Navigate to the following directory on the Secure Agent machine:

   %Secure Agent installation directory%/ext/connectors/thirdparty/

2. Create a folder and add the driver JAR file (cdata.jdbc.linear.jar) based on the type of mapping that you want to configure.

   For mappings, create the following folder and add the driver JAR file:

   informatica.jdbc_v2/common

   For mappings in advanced mode, also create the following folder and add the driver JAR file:

   informatica.jdbc_v2/spark

3. Restart the Secure Agent.

Connecting to Linear in Informatica Cloud

After installing the driver JAR file, you are ready to configure your connection to Linear in Informatica Cloud. Start by clicking the Connections tab and clicking New Connection. Fill in the following properties for the connection:

• Connection Name: Name your connection (i.e.: CData Linear Connection)
• Type: Select "JDBC_V2"
• Runtime Environment: Select the runtime environment where you installed the Secure Agent
• JDBC Driver Class Name: The name of the JDBC driver class: cdata.jdbc.linear.LinearDriver
• JDBC Connection URL: Set this to the JDBC URL for Linear. Your URL will look similar to the following:
  
  

  jdbc:linear:AuthScheme=APIKey;APIKey=myAPIKey;

  You can authenticate to Linear with a personal API key or with OAuth 2.0. The API key is the simplest option for connecting with your own Linear account.

  Authenticating with an API Key

  Set the following connection properties:

  • AuthScheme: Set this to APIKey.
  • APIKey: A Linear personal API key.

  To create a personal API key, log in to Linear, open Settings > Security & access > Personal API keys, select New API key, and create it. Copy the key immediately, because Linear shows it only once.

  Authenticating with OAuth

  OAuth requires a custom OAuth application registered in Linear (Settings > API > OAuth applications), which provides the OAuthClientId and OAuthClientSecret. Two flows are supported:

  • Authorization code: Set AuthScheme to OAuth, InitiateOAuth to GETANDREFRESH, and provide OAuthClientId, OAuthClientSecret, and the CallbackURL defined in your application (e.g., http://localhost:33333). The driver opens Linear in your browser so you can grant access.
  • Client credentials: Set AuthScheme to OAuthClient and provide OAuthClientId and OAuthClientSecret. This authenticates the application itself, with no browser interaction, and suits machine-to-machine integrations.

  By default, the driver requests the read,write scopes. The driver refreshes the access token automatically when it expires.

  Built-In Connection String Designer

  For assistance in constructing the JDBC URL, use the connection string designer built into the Linear JDBC Driver. Either double-click the .jar file or execute the .jar file from the command-line.

  
      java -jar cdata.jdbc.linear.jar
      

  Fill in the connection properties and copy the connection string to the clipboard.

  
• Username: Set this to a placeholder value (since Linear does not require a username)
• Password: Set this to a placeholder value (since Linear does not require a password)

Create a Mapping for Linear Data

With the connection to Linear configured, we can now access Linear data in any Informatica process. The steps below walk through creating a mapping for Linear to another data target.

1. Navigate to the Data Integration page
2. Click New.. and select Mapping from the Mappings tab
3. Click the Source Object and in the Source tab, select the Connection and set the Source Type
4. Click "Select" to choose the table to map
5. In the Fields tab, select the fields from the Linear table to map
6. Click the Target object and configure the Target source, table and fields. In the Field Mapping tab, map the source fields to the target fields.

With the mapping configured, you are ready to start integrating live Linear data with any of the supported connections in Informatica Cloud. Download a free, 30-day trial of the CData JDBC Driver for Linear and start working with your live Linear data in Informatica Cloud today.
