Round Trip On-Premise Integration (Part 1) – ICS to EBS by Greg Mally
December 7, 2016 Leave a comment
One of the big challenges with adopting Cloud Services Architecture is how to integrate the on-premise applications when the applications are behind the firewall. A very common scenario that falls within this pattern is cloud integration with Oracle E-Business Suite (EBS). To address this cloud-to-ground pattern without complex firewall configurations, DMZs, etc., Oracle offers a feature with the Integration Cloud Service (ICS) called Connectivity Agent (additional details about the Agent can be found under New Agent Simplifies Cloud to On-premises Integration). Couple this feature with the EBS Cloud Adapter in ICS and now we have a viable option for doing ICS on-premise integration with EBS. The purpose of this A-Team blog is to detail the prerequisites for using the EBS Cloud Adapter and walk through a working ICS integration to EBS via the Connectivity Agent where ICS is calling EBS (EBS is the target application). The blog is also meant to be an additional resource for the Oracle documentation for Using Oracle E-Business Suite Adapter.
The technologies at work for this integration include ICS (Inbound REST Adapter, Outbound EBS Cloud Adapter), Oracle Messaging Cloud Service (OMCS), ICS Connectivity Agent (on-premise), and Oracle EBS R12. The integration is a synchronous (request/response) to EBS where a new employee will be created via the EBS HR_EMPLOYEE_API. The flow consists of a REST call to ICS with a JSON payload containing the employee details. These details are then transformed in ICS from JSON to XML for the EBS Cloud Adapter. The EBS adapter then sends the request to the on-premise connectivity agent via OMCS. The agent then makes the call to EBS where the results will then be passed back to ICS via OMCS. The EBS response is transformed to JSON and returned to the invoking client. The following is a high-level view of the integration: Prerequisites read the complete article here.
