Oracle Integration Cloud (OIC) offers a wide range of pre-built adapters that facilitate seamless integration between different applications, services, and systems. These adapters serve as connectors and bridges to link OIC with various endpoints, making it easier to exchange data and perform integration tasks.

Some common types of Oracle Integration Cloud adapters include:

1. Application Adapters: These adapters are designed to connect OIC with various enterprise applications like Oracle Cloud Applications (e.g., Oracle ERP Cloud, Oracle HCM Cloud, Oracle CX Cloud), third-party applications (e.g., Salesforce, SAP), and on-premises systems (e.g., Oracle E-Business Suite).

2. Technology Adapters: These adapters enable integration with technology components such as databases (e.g., Oracle Database, Microsoft SQL Server), file servers (e.g., FTP, SFTP, File), messaging systems (e.g., JMS, IBM MQ), and web services (e.g., SOAP, REST).

3. Social Adapters: These adapters allow OIC to integrate with social media platforms like Twitter, Facebook, LinkedIn, and more.

4. IoT (Internet of Things) Adapters: OIC supports IoT adapters that enable integration with IoT devices and platforms to process IoT data and trigger actions based on that data.

5. On-Premises Connectivity Agent: OIC provides a connectivity agent that you can install on your on-premises network to securely connect and integrate with on-premises applications and systems that are not exposed to the internet.
