Oracle Integration Cloud (OIC) is Oracle’s flagship application integration cloud product and is part of the wide array of PaaS offerings on OCI. Throughout this blog OIC refers to OIC Integration 3<\/a>.<\/p>\n\n\n\n

OIC provides a host of tools in terms of adapters, integration palette actions, integraton patterns and prebuilt integrations to help customers solve various use cases using the event driven approach.
Firstly let us look at the Integration options supported by OIC for creating event driven integrations<\/p>\n\n\n\n

1. Native OIC Pub\/Sub – Publisher and Subscriber pattern using native OIC constructs
2. Using OCI Messaging platforms – OCI Streaming Service\u00a0
3. Business events Subscriptions from Oracle SaaS Applications (ERP, SCM, HCM, CX, OFSC, SvC, EBS)
4. Technology Adapters – Oracle AQ, Oracle Weblogic JMS, IBM MQ, OCI Queues, Amazon SQS
\u00a0<\/p>\n\n\n\n

Additionally for sake of completion, we will also look into this last category<\/p>\n\n\n\n

5. OIC Adapters for external applcations event subscription – (Azure, SAP Successfactors, Shopify, SAP Ariba)

1. Create Integrations to Publish and Subscribe using OIC Native Pub\/Sub<\/h2>\n\n\n\n

OIC provides publish subscribe messaging support using underlying OCI services. Any application integration can publish predefied events and any event subscriber integrations in OIC can subscribe to and consume these events. The event types can be XML or JSON and are defined on OIC before Pub Sub integrations can use them. This pattern is the highly performant and scalable due to inbuilt native capabilities. It can be used for a wide variety of usecases to achieve real time, high volume event based integration between applications.<\/p>\n\n\n\n

Depicted below is one representative architecture where OIC publisher and subscriber integrations used to integrate between Oracle SaaS applications, OKE<\/a> Microservices and database services. Publisher and subscriber integrations are used to convert messages from applications into events and achieve asynchronous integration using OIC pub\/sub pattern.<\/p>\n\n\n\n

Here are the brief steps to create Pub Sub Interations using OIC.<\/p>\n\n\n\n

    \n
  1. 1. Create an event type by providing either a json sample or an XML schema for the event payload.<\/li>\n<\/ol>\n\n\n\n

    An event type once created can be reused across multiple subscribers and publisher integrations.<\/p>\n\n\n\n

      \n
    1. 2. Create an event publishing integration.<\/li>\n<\/ol>\n\n\n\n

      This integraton is a producer of an event. This can be an integration of any pattern that uses a ‘Publish event’ action to push an event to native OIC event platform. Note that a publisher integration does not have to be of pattern “event” during Integration creation time. Drag The ‘Publish event’ action to the integration canvas, which allos to select the type of event (created in step 1 above) intended for publishing<\/p>\n\n\n\n

        \n
      1. 3. Create an event subscription integration\u00a0\u00a0 \u00a0<\/li>\n<\/ol>\n\n\n\n

        Use the integration pattern type ‘Event’ which is reserved for event subscribers. The trigger to this integration is an event. The trigger is configured to register itself as an event listener to a specific type of event. (which was created in step 1 above) When deactivating a subscriber integration, one can choose to retain the event subscription which allows the subscriber to accumulate events and receive then upon subsequent activation.<\/p>\n\n\n\n
