Beyond Bitcoin: Oracle Prepare Blockchains for Industrial Use by TC Currie

image

There’s been a lot of talk recently about blockchains beyond its original use for supporting Bitcoin. Earlier this year, we covered a session in London where the takeaway from the panel was there are too many problems to be solved. But that was in February, and a lot has changed since then.

Judging from some of the blockchain sessions at the recent Oracle OpenWorld conference, the emerging potential uses for blockchain are kind of staggering.

Blockchain uses a technology also described as a “distributed ledger.” That’s an obvious fit for finance, which is all about ledgers, but it turns out the distributed ledger concept can be applied to — well, to almost everything.

According to BlackBook Research, 70 percent of health insurance payers are planning to have blockchain integrated into their systems by the beginning of 2019. That’s 15 months from now. Among the payers with over 500,000 members, that number climbs to 98 percent, with 14 percent currently testing blockchain systems. Read the complete article here.

7 Things Every Developer Should Know About Oracle Blockchain Cloud Service by Jay Chugh

image

At Oracle Open World, Oracle launched the new and exciting enterprise-grade Oracle Blockchain Cloud Service. The launch generated overwhelming interest from press, analysts, and conference attendees as evident by standing-room only attendance in nearly all Blockchain sessions.

What was equally noteworthy was the tremendous interest from software developers.  The demos and hands-on labs showcased just how easy it is for any developer to work with Oracle Blockchain Cloud Service, unlike anything they have seen in the market so far. Oracle’s Blockchain Cloud Service enables developers to build smart contracts, integrate with existing business processes, or even create new blockchain applications within minutes, without worrying about running and managing Blockchain environments.

Based on conversations with developers that are breaking new ground in Blockchain, here is a compilation of top seven things every developer should know about Oracle’s Blockchain Cloud Service.

  1. Open Source and Open Standards Based

Oracle’s blockchain is based on open source Hyperledger Fabric v1.0 code, which supports standard protocols such as REST and gRPC. For developers, it means that they have complete visibility into the product roadmap and may directly participate in development through open source community. This also means that developers can easily integrate their existing Hyperledger-based blockchain networks and applications with Oracle Blockchain Cloud Service.

  1. Simpler to Develop and Deploy Smart Contracts. Read the complete article here.

NIST Releases Blockchain Report for Business Beginners by Annaliese Milano

image

The National Institute of Standards and Technology – a non-regulatory agency of the U.S. Department of Commerce – has released an overview of blockchain technology, aimed to clarify the central characteristics of the technology, its limitations and common misconceptions.

The document targets beginners to blockchain, specifically organizations considering adopting the technology, and those trying to move beyond the "hype" surrounding blockchain. The authors remind readers that businesses are often tempted by new technology, but that they should be sure that the blockchain is appropriate for their operations before diving in.

"A company’s IT managers need to be able to say, we understand this, and then be able to argue whether or not the company needs to use it based on that clear understanding", said Dylan Yaga, computer scientist and one author of the report. Read the complete article here.

Jarvis Pizzeria: Third step in Implementing the Order Processing, Correlation

image

In our blog entries the First Step and the Second Step there was described how multiple pizza’s could be prepared using a multi-instance subprocess. Although we saw this working correctly, the subprocess was configured to prepare pizzas sequentially, see the screenshot below:

However, due to the success of the Jarvis Pizzeria, new equipment was purchased. Two brand new ovens were installed, enabling the Jarvis enterprise to prepare three pizza’s simultaneously…awesome!

To make optimal use of our equipment we should configure the process to prepare pizzas in parallel, see the screenshot below:

Those of you who have worked with multiple asynchronous calls from the same process (or even BPEL, back in the days) should remember the need for correlating the invocation with the corresponding callback.

Lets first try this with setting up message based correlation. I.e. from the calling process we initiate a correlation with a unique key which is send to the called process. The called process returns this unique key and hence the calling process knows on which callback it has to wait.

In the properties of the “Start of Preparation” activity we have the option to initialize the correlation: Read the complete article here.

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

image

 

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. Read the complete article here.

Jarvis Pizzeria: Getting Started with Dynamic Processes (ACM) by Richard Olrichs & Marcel van de Glind & Marc Kuijpers

image

Getting started with the new integration cloud, the cloud that brings ICS, VBCS and PCS together. But it also includes the introduction of dynamic processes, Oracle’s new approach for adaptive case management. This introductory blog consists mainly of an overview of the different parts of dynamic processes. In addition, some differences between PCS and the Integration Cloud are discussed.

First step: import the Jarvis Pizza Preparation application. The location of this menu option is changed but the functionality is not. So we do this in two quick steps. Read the complete article here.

Jarvis Pizzeria in Case Management Style by Richard Olrichs & Marcel van de Glind & Marc Kuijpers

image

As our business grows and our digitalization kicks in, it is time to reevaluate our process setup. We are happy with our processes in Process Cloud, they are easy to set up and we can manage our process from Ordering a Pizza al the way through to delivery.

However as with any BPMN, this a very structured process. Sometimes we require a bit more flexibility.

We had a good chat with our friends from Oracle and we were very pleased to hear that our wish to become more flexible aligned with their plans for PCS. We were thinking towards a Case Management solution for our pizzas and got a very satisfying answer.

In October 2017, Oracle released the Oracle Integration Cloud (OIC), not to be confused with the Integration Cloud Service (ICS). The Integration Cloud brings together several Low Code products. VBCS, Visual Builder Cloud Service, for developing user interfaces, ICS, Integration Cloud Service, for creating your integrations in the Oracle Cloud. Stream Analytics, for smart analytics on your integrations & processes. And last, but certainly not least PCS, Process Cloud Service, that in their new release includes Dynamic Processes. These Dynamic Processes have a lot of Case Management features and have a notation that feels a lot and reminds us of CMMN. Read the complete article here.

Streamline Development in Oracle Projects by Markus Lohn Setup a Fusion Middleware environment for testing and development purposes in less than 60 minutes!

image

Dynamic markets and the constant reaction to changing conditions is a decisive success factor for companies today. All measures taken in the past years in the field of software development were aimed at supporting and facilitating this dynamics technically. Development times had to be drastically reduced and results made available for review earlier than before. IT has achieved a different status in the company today. IT can be used to tap new growth areas and strengthen existing customer relationships. For this reason, it is important to address the question of how quickly a developer can work productively in a new project. In this blog post, tools and procedures are presented to enable a developer to be productive in the project in less than a day. In detail, this means, for example, editing a user story from the backlog.

Experience shows that setting up the development environment in many projects involves many manual steps. Missing or inadequate documentation slows down this process considerably. Sometimes it takes several days to set up. Through the approach presented here, the developer is able to be supplied within a few hours with a development environment. Due to the high level of automation, there is no need for comprehensive documentation. Errors are largely avoided in this way. The figure below shows typical components that belong to a development environment. In this blog post, I focus on using tools in projects using Oracle technologies (SOA / Integration, ADF, Java EE). However in general these guidelines can be applied to Open Source as well. Read the complete article here
