Jarvis Pizzeria: Setting up the Dynamic Process by Richard Olrichs & Marcel van de Glind & Marc Kuijpers

In this blog we will implement a first version of the preparation of an order using a dynamic process. We continue where blog one stopped. The imported order process is extended with an example dynamic process.

We open the DynamicOrderProcess, which should still contains the example. We will build this so that it contains the Pizza ordering process. However, when opening the Process, we can see that the example is no longer there. Apparently, the example is not saved, maybe because we did not make any changes to it? Let’s create the example again, and then change it immediately.
The first step we take to make it our own is to define the stages. Rename the ‘First Stage’ in ‘Ordering’. The ‘Second Stage’ in ‘Preparation’ and add another third stage ‘Delivery’.
For changing the name of a stage, select the pencil in the title bar to get to to properties.
In there change the name. Use the add icon just above the pencil to add the third stage.

Now let’s save our changes and see what happens to this modified ‘example’. We close the Dynamic process, and then open it again.
However, our changes have disappeared as well. The whole example is gone once again. How is that possible? Is something thoroughly wrong with the application or is an example application just an example, and can it not be saved? Anyway, it is good to realize the example application is there as an example and not like a QuickStart application.
So let’s restart again. Now we will not create an example, but just add the different stages.
After doing this, yet again, let’s put it to the test. We save our application, close it and reopen it. Yeah! Alright! Now the changes persists, so it does have something to do with the example mode. Read the complete article here.

Is BPM Dead, Long Live Microservices? By Luis Weir

December 6, 2018 Leave a comment

With the massive uptake of Microservices Architecture -industry wide- and with it, the adoption of patterns such as Event Sourcing, CQRS and Saga as the means for Microservices to asynchronously communicate with each and effectively "choreograph" business processes, it might seem as if the days of process orchestration using BPM engines (e.g. Oracle Process Cloud now also part of Oracle Integration Cloud, Pega, Appian, etc) or BPEL (or BPEL-like) engines are over.

Although the use of choreography and associated patterns (such as the aforementioned) makes tons of sense in many use cases, I’ve come across a number of them where choreography can be impractical.

Some examples:

  • Data needs to be collected and aggregated from multiple services -e.g. check the Microservice.io Composition pattern. Note that this pattern doesn’t necessarily implies that an orchestration is required. Could be that data is collected and aggregated (not transformed) into a single response. But if data collected from multiple sources needs to also be transformed into a common response payload, then it feels pretty close to one of the typical use cases for orchestration.
  • The process is human-centric and can’t be fully automated. Basically at some point a human has to take an action in other for the process to complete (e.g. approval of a credit card application, or a credit check) -BPM/Orchestration tools tend to be quite good at this.
  • There is a need to have very clear visibility of the end to end business processes. In traditional BPM tools, this is fairly straight forward, with Choreography / Events, although possible to monitor individual events, a form of correlation would be required to build an end to end view on the status of a business process.

Integration Cloud – Lets POC and get our feet wet by Kevin King

December 2, 2018 Leave a comment

image

At a recent client, I had a "citizen integrator" ask me to show them some of the orchestrations that I’ve created in ICS, and how I went about creating them.  I began showing off some of the integrations, and some of the POCs that I created.  I didn’t get very far until he stopped me and asked, how I was able to invoke the integrations to test them.  This is when I realized he had previously attempted to create some integrations, but didn’t understand what he created, or how to trigger them and see them in action.

How do I test my integration on Oracle Integration Cloud Service (ICS)?

So, let’s take a common scenario, where you are asked to verify that an integration works from ICS or as a developer you want to explore a new integration you are going to interact with. We are going to look at the most common type of integrations, ‘Orchestration’.  Oracle has this all documented here, so feel free to jump there for more thorough documentation!

On creating a new Orchestration integration, the first decision is ‘What triggers this integration?’.  There are two options,  ‘Schedule’ and ‘Application event or business object’… So what are these, and what should I choose.

Trigger 1: Schedule

Let’s start with Scheduled, as this is the quickest option to ‘try out’ an integration or mapping.

Creating a ‘Scheduled’ orchestration is meant for exactly as it sounds, a schedule.  You can define it to run every minute, every hour, every Monday, whatever the requirement is…  The bonus feature about this option is the ‘Submit Now’ selection.  This makes it very easy to test!

Now, let’s create a new Orchestration, and select ‘Scheduled’ (make sure you follow best practices and add it to a package!). Read the complete article here.

Teaching How to Recover Errored Instances with Oracle Integration Cloud by Carlos Rodriguez Iturria

December 1, 2018 Leave a comment

Building Enterprise integrations in the Cloud with iPaaS brings many benefits, including among others: simplicity, agility and scalability. However, these benefits should not be taxed by having a weak core, not able to properly manage common enterprise requirements, such as error management. I’ve been a bit disappointed with how most iPaaS vendors handle runtime exceptions of integration flows. A typical example of this, is not being able to support dehydration for asynchronous flows (i.e. dehydration is crucial to supporting long-running instances by saving their memory state into a database, until a correlation invocation, a.k.a call-back, wakes it up to continue with the flow). This causes that when an error occurs, recovery has to start from the beginning of the integration flow that failed.

In these situations, we would have to either design an integration to be fully idempotent and stateless across all its partner links (service invocations), which is not always possible. Another way to do it is by manually handling the recovery of errored scenarios, this is to avoid state inconsistency across the previous service invocations in the orchestration, prior to the error… But then if we have to manually handle compensation, what about iPaaS being easier? Read the complete article here.

Teaching How to Design and Secure an API with Oracle API Platform by Carlos Rodriguez Iturria

November 29, 2018 Leave a comment

 

imageThe image below shows an easy to understand architecture with the various components mentioned above:

Are you ready? Let’s do it!

Pre-requisites

It is expected that you have access to the Oracle API Platform, if not, you can request a free trial at https://cloud.oracle.com/tryit

Also, it is assumed that you have already created your GitHub repository by forking from the MedRec SolutionsANZ repository and obtaining with this the full MedRec NodeJS application with its own API Swagger definition. If you have not completed these pre-requisites steps, please refer to this precursor blog.

API Design – Creating the API Definition with Apiary

In this section you are going to create a new personal Apiary account (in case you still don’t have one) and create a new API Project using the existing MedRec API Swagger definition from the MedRec SolutionsANZ repository.

If you still don’t have a personal Apiary account, follow the next steps:

  • Go to https://apiary.io/
  • You can click on Sign up on the top right corner or in this case we can sign up for free git GitHub, assuming that you already have a GitHub account from the previous blog.
