Integrate PostgreSQL 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 PostgreSQL, you get live access to PostgreSQL data, directly within Informatica Cloud. In this article, we will walk through downloading and registering the Cloud Secure Agent, connecting to PostgreSQL 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 PostgreSQL data through the JDBC Driver, install the Cloud Secure Agent.

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

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

Connecting to the PostgreSQL JDBC Driver

With the Cloud Secure Agent installed and running, you are ready to connect to PostgreSQL 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.postgresql.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 PostgreSQL in Informatica Cloud

After installing the driver JAR file, you are ready to configure your connection to PostgreSQL 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 PostgreSQL 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.postgresql.PostgreSQLDriver
• JDBC Connection URL: Set this to the JDBC URL for PostgreSQL. Your URL will look similar to the following:
  
  

  jdbc:postgresql:User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5432;

  To connect to PostgreSQL, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the data provider connects to the user's default database.

  SSH Connectivity for PostgreSQL

  You can use SSH (Secure Shell) to authenticate with PostgreSQL, whether the instance is hosted on-premises or in supported cloud environments. SSH authentication ensures that access is encrypted (as compared to direct network connections).

  SSH Connections to PostgreSQL in Password Auth Mode

  To connect to PostgreSQL via SSH in Password Auth mode, set the following connection properties:

  • User: PostgreSQL User name
  • Password: PostgreSQL Password
  • Database: PostgreSQL database name
  • Server: PostgreSQL Server name
  • Port: PostgreSQL port number like 3306
  • UserSSH: "true"
  • SSHAuthMode: "Password"
  • SSHPort: SSH Port number
  • SSHServer: SSH Server name
  • SSHUser: SSH User name
  • SSHPassword: SSH Password

  SSH Connections to PostgreSQL in Public Key Auth Mode

  To connect to PostgreSQL via SSH in Password Auth mode, set the following connection properties:

  • User: PostgreSQL User name
  • Password: PostgreSQL Password
  • Database: PostgreSQL database name
  • Server: PostgreSQL Server name
  • Port: PostgreSQL port number like 3306
  • UserSSH: "true"
  • SSHAuthMode: "Public_Key"
  • SSHPort: SSH Port number
  • SSHServer: SSH Server name
  • SSHUser: SSH User name
  • SSHClientCret: the path for the public key certificate file

  Built-In Connection String Designer

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

   java -jar cdata.jdbc.postgresql.jar
   

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

Create a Mapping for PostgreSQL Data

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

1. Navigate to the Data Integration page 👁 Image
   
2. Click New.. and select Mapping from the Mappings tab 👁 Image
   
3. Click the Source Object and in the Source tab, select the Connection and set the Source Type 👁 Selecting the Source Connection and Source Type
   
4. Click "Select" to choose the table to map 👁 Selecting the Source Object
   
5. In the Fields tab, select the fields from the PostgreSQL table to map 👁 Selecting Source Fields 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. 👁 Selecting the Target Field Mappings
   

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