Installing SOACS Hybrid Agent EM13C by Kiran Tailor

In my last post we set up a hybrid agent and installed an OTD agent, in this post we shall create a SOACS agent. I am assuming you have already done the first few steps that were mentioned in my last post OTD Hybrid Agent (http://puredba.co.uk/oracle-traffic-director-otd-hybrid-agent-em-13c/)

1. On SOACS Target Host

Insert the OMS server details into the host file:

Create the Agent Directory

Integration Design Pattern – Synchronous Facade for Asynchronous Interaction by Shreenidhi Raghuram

Introduction

In this blog, we will explore a Hybrid Message Interaction pattern, which combines the characteristics of traditional Synchronous Request-Reply and Asynchronous patterns. We will also see, the need for such a design pattern and how it can be implemented using Oracle SOA Suite.

Need for this Design Pattern

A Hybrid Synchronous-Asynchronous message exchange pattern is a requirement that pops up often in architectural discussions at customer engagements. The below discussion summarizes the need for such a design pattern.

Consider the following scenario:

A Web Client end-user fills in a form and submits a request. This is a blocking request and the client waits for a reply. The process is expected to reply to the user within a short period and let us assume that the client times out after 30 seconds. In a happy path, the backend systems are responsive and user receives the response within 30 seconds. This is shown in the below ‘Synchronous – Happy Path’ diagram.

Now, consider if a backend delay or system outage prevents a response from the website within 30s. All that the client receives is a Timeout Error. No further information is available and the user can only refill and resubmit the form, another time! This is shown in the below ‘Synchronous – Not so Happy Path’ diagram.

The above solution is designed for the happy path. It can even be optimized for a high throughput in the happy path scenario. But for the negative path, it is desirable to have a more responsive and user friendly behavior. We should note that any design for the negative scenario would inherently be Asynchronous in nature, as we do not want the user to wait for the delayed response. Rather the user should be notified by other means whenever such a response is available.

Even though the percentage of requests that end up in the delayed scenario may be quite less, it is still desirable that such requests are handled in a more user friendly manner. We also want to achieve the Asynchronous error handling without sacrificing the high performance of a purely synchronous interaction.

The next section proposes such a design. Read the complete article here.

Integration Cloud Service LinkedIn adapter by Rolando Carrasco

After being trying some weeks/months ago to make this happen, finally the Linkedin adapter is working in my Oracle ICS instance.

The adapter supports these operations:

In this blog post we will show the scenario of Status Update. I think this is a good one, since you can implement something with your HR department that everytime they open a new position, it can be automatically updated in Linkedin. Wouldn’t that be great? Or if someone quits or move, but at the end a new position is opened, then with the upcoming steps you can achieve it.

The first thing is to login in Oracle ICS and go to the connection section to create a new one. Then look for Linkedin adapter:

Put a name on it:

Configure your Client ID and Client Secret that u will get after creating an application. Read the complete article here.
