Oracle Integration Cloud (OIC) is a powerful cloud-based integration platform designed to automate processes across cloud and on-premise applications. It provides a complete and modular solution for real-time, batch, and event-based integration and data synchronization.

A Connectivity Agent in Oracle Integration Cloud is a light-weight program that you can install on-premises to provide a secure connection between the Oracle Integration Cloud Service and on-premises systems such as databases and Web Services.

Here are some key points regarding Connectivity Agent:

1. Secure Connection: The Connectivity Agent creates a secure, encrypted communication channel to Oracle Integration Cloud over HTTPS. This eliminates the need to open additional ports in your corporate firewall.

2. Support for Different Protocols: It supports various protocols such as JDBC, File, FTP, and SOAP.

3. Automatic Updates: The agent automatically downloads updates, patches, and fixes from Oracle Integration Cloud, which reduces maintenance costs and ensures your integration stays current.

4. Scalability: Multiple connectivity agents can be installed and managed to scale as the business demand grows.

Integration process:

1. Install the Connectivity Agent: Download and install the connectivity agent in the on-premises system. Make sure that the prerequisites for installing the agent are met.

2. Register the Agent: Register the agent with the Oracle Integration Cloud using the unique identifier provided during the installation.

3. Configure the Connection: In Oracle Integration Cloud, configure the connection to the on-premises system using the registered agent.

4. Build Integration: Now, you can build integrations in Oracle Integration Cloud using the on-premises connection.

5. Activate and Monitor Integration: Activate the integration, and monitor its run-time performance in Oracle Integration Cloud.
