Artificial intelligence, autonomous databases, blockchain, chatbots, Internet of Things, and more: Oracle executives discuss emerging technologies. By Michael Hickins

Those of us who have been waiting for the future to arrive since, well, forever can finally rejoice. The future has arrived in the form of computer interfaces that feel human; self-learning software; self-healing autonomous databases; sensors that provide us with actionable, critical data from far afield; hyper-realistic visualization technology; and transaction systems that are simultaneously private and transparent.

What’s most surprising, though, is that the experience of the future is incredibly easy for Oracle’s customers to deploy. At this year’s Oracle OpenWorld in San Francisco, California, Oracle leaders announced new products and discussed upcoming capabilities that put the power of several emerging technologies into the hands of Oracle customers.

Enterprise-Class Artificial Intelligence

Artificial intelligence (AI) is the most fundamentally important and pervasive of emerging technologies. Larry Ellison, executive chairman and CTO at Oracle, calls machine learning, a subset of artificial intelligence, “every bit as revolutionary as the internet.”

Oracle is using AI, for instance, to power its autonomous database and chatbots (more on those to follow), and to turn the trillions of data points streaming from connected devices into actionable information.

“For years and years and years, artificial intelligence did not live up to its promise,” Ellison said during his opening keynote address at Oracle OpenWorld on October 1, “but there is a new type of AI.” Read the complete article here.

Quick look into Oracle BPM 12c REST APIs by Sebastian Marucci

September 8, 2018 Leave a comment

Back in mid-2014, Oracle was releasing Oracle BPM 11g Bundle Patch 3 and with it, the first version of its BPM REST APIs. That first cut was a good starting point, but it just offered a limited amount of functionality (find my previous post here). In this post, we’ll take a look at the BPM REST APIs version 12.2.1.2, released in August 2016, and see how they evolved after 2 years.

The list of available services can be obtained by accessing to http://yourserver:port/bpm/services/rest/application.wadl.

The picture above shows all the REST services included in this new version; highlighted in yellow are the new services introduced since the first version of the REST APIs. There’s one curious thing, the two processes services (1.0/processes and /processes). Like in the very first version of processes service, if you execute getProcess operation, the response is just “Processes.”. Likewise with runtime service, if you execute getRuntime operation, the response is an empty string. Read the complete article here.

Unshackle the Business – Best Practices in UI and Process Designs by Mark Peterson

September 7, 2018 Leave a comment

To remain competitive, companies have to continually drive down costs while maintaining value in the products and services they offer. One area where companies look to reduce costs is in Business Process Management (BPM).

When it comes to IT expenditures, some companies may invest a small fortune in BPM, while others may simply rely on basic tools, such as spreadsheets and Post-it notes. Regardless of the amount spent, if the tools are hard to use or the process is cumbersome then your business has become shackled and is wasting time and energy.

Are your company’s internal business processes helping or hurting efficiency? Take this simple assessment:

  • Do your employees have relevant and useful tools to complete their work or do they waste time navigating complicated or out-of-date systems?
  • Do their tools or user interfaces (UIs) involve countless forms or spreadsheets or are they streamlined and concise?
  • Do the business processes or workflow they must follow slow them down or accelerate their work?

AVIO has developed best practices in UI and business process design that help organizations reduce their cost of doing business and increase worker satisfaction. These practices and designs, when implemented, empower employees and help drive organizational change, which can ultimately affect the company’s bottom line. Read the complete article here.

Jarvis Pizzeria: Deploying and Reverting to Snapshots by Richard Olrichs & Marcel van de Glind

September 6, 2018 Leave a comment

image

When working on a PCS application, you save and publish your changes often. However, when you publish a certain state of the application, you can decide to create a snapshot of this state of the application.

This can be very helpful if the publish represents a certain version of the application. Later these snapshots can be deployed or reverted to in case you want to roll back to a previous version. It is also possible to see what was in the application at the time of the snapshot creation.
In this blog we will show you how to work with snapshots.

When publishing, in the popup on the right hand side there is a option to ‘Make Snapshot’, when this checkbox is checked you can enter a name for the snapshot, in this case the snapshot will represent Jarvis 1.0!

After the Changes have been published and a snapshot is created we go to the deploy screen by clicking the deploy button. Read the complete article here.

Jarvis Pizzeria: Workaround for XSD list-element issue in WebForms by Richard Olrichs & Marcel van de Glind

September 5, 2018 Leave a comment

image

In a previous blog we have made notices that it is not possible to create a Webform based on a xsd-type that contains a list elements. In our case a list of pizza ingredients.

In this post we will give an alternative way to create a webform that displays the data, including the list of ingredients. For this we have created a new form IngredientsWebForm.

As we tried before, It does not work to drop the full business object on the canvas. Therefore, we have now made up the form of separate components. 4 input text components, of which 2 are listed in a table component and a number component that is also displayed in the table. This results in the following format.

This is the form we will use for all different presentation (one of our next posts will be about different presentation of one and the same WebForm), but first we will use it in its default. In the top left corner you see that this is the main presentation which is also the default. It is quite logically that it is the default, because it’s the only one 🙂

After saving the WebForm we go back to the process to update the various tasks.

For each task we have switched the form reference to the new IngredientsWebForm. The below example shows this for the ‘Prepare Pizza Crust’ task. The example also shows that the Main presentation is selected for the task. Read the complete article here.

Jarvis Pizzeria: Human Tasks: Design First WebForms in PCS by Richard Olrichs & Marcel van de Glind

September 4, 2018 Leave a comment

image

To create simple Human Tasks we use web forms in Process Cloud Service (PCS). Within the Delivery Process of the Jarvis Pizzeria, we are going to implement the HT for ‘Try Contacting the Customer’. This human task should become available after we have checked that the Customer is not a member and we do not know his email address. 

Try contacting the non-regular / member from Jarvis Pizzeria, in the swimlane of the CallCenter.

We will take the Design First approach, meaning we will design the form and know what data objects we need afterwards, instead of looking at the data we need for the Human Task first.

This means we can start by creating a new web form.

In the properties window from the task we click the add ‘+’ icon next to the Form.

We want to, but also only can select the ‘New Web Form’ option, the basic form is the old form used in previous versions of PCS. It is still available in the engine for backwards compatibility. Selecting this option will open the ‘Create New Web Form’. Read the complete article here.

Jarvis Pizzeria: Notification Task in PCS by Richard Olrichs & Marcel van de Glind

September 3, 2018 Leave a comment

 

imageSo far we have covered most standard components of the PCS suite. However, we haven’t looked at the “Notification Task” in-depth yet. We have used the on-premises variant at various projects but it was the hassle of setting up the User Messaging Service (UMS) that made you reluctant to use this feature on beforehand. Will the PCS variant be a gamechanger? Let’s find out!

We implemented a basic process with a standard notification task and configured it to send an email to marc.kuijpers@rubix.nl. The implementation details are shown below:

We deployed the process and sent a SOAP message to the corresponding endpoint. Looking at our instance in the workspace we see the following successful instance:

Yaaay! But before we ship this version to a production environment let’s see if we have received an email…..Unfortunately the answer is no 😦

Hmm, have we missed a setting? Do we have to configure something? Crawling to the settings in the Business Process Workspace we encountered the infrastructure tab. And it turns out that this is the place where we can configure the notification service. Read the complete article here.

Jarvis Pizzeria: Different presentations for the same WebForm by Richard Olrichs & Marcel van de Glind

September 2, 2018 Leave a comment

image

In a previous blog we created a default WebForm for the Pizza Preparation process. In each human interaction of the process we used this default WebForm with the default presentation. In this post we will create a different presentation for each human interaction in the process.

  1. Crust Preparation Will only show the pizza name and size. Both fields are editable.
  2. Filling the Pizza Shows alle data. The pizza name and size are read-only. The ingredients are editable. It’s also possible to add or remove ingredients.
  3. Put in Oven All data is shown read-only.
  4. Get out the Oven The Pizza naam and size are shown read-only.

As a starting point for this blog, we use the end result of the above mentioned blog. We begin by adding presentations to the IngredientsWebForm. Read the complete article here.

Oracle Management Cloud: Find SOA Suite issues quick and easy by MichelSchildmeijer

September 1, 2018 Leave a comment

One of the services which are delivered by the Oracle Management Cloud is the monitoring of infrastructure. Now in this case, infrastructure spans from host to software platform. In this blogpost I will try to explain how you can effectively behind issues in your Oracle SOA Suite operational environment. OMC can monitor some parts specific to the SOA suite, in fact all the engines which are enclosed in a SOA Suite running envrioment. These are:

  • The BPEL engine
  • The Mediator engine
  • The Descion Service Engine or Business Rules Engine

I simulated a test which processed a lot of transactions through the payment process of my company. SOA Suite was handling this payment process through an OSB service in the frontend and an enrichment though a SOA composite which did a validation based on some rules.

The company deployed a new release and adapter to get more benefit out of it.

During tests, I suddeny received an alert from OMC that the error rate on the BPEL engine was increased. When I looked into the Performance table of my soainfra entity I found the following:

Click on the SOA Composite field I could detect which composite was causing the error, the ValidatePayment. Read the complete article here.

OSB: Disable Chunked Streaming Mode recommendation by Martien van den Akker

August 31, 2018 Leave a comment

Intro

These weeks I got involved in a document generation performance issue. This ran for several months, maybe years even. But it stayed quite unclear what the actual issue was.
Often we got complaints that document generation from the front-end application (based on Siebel) was taking very long. End users often hit the button several times, but with no luck. Asking further, it did not mean that there appeared a document in the content management system (Oracle UCM/WCC). So, we concluded that it wasn’t so much a performance issue, but an exception along the process of document generation. Since we upgraded BI Publisher to 12c, it was figured that it might got something to do with that. But we did not find any problems with BI Publisher, itself. Also, there was an issue with Siebel it’s self, but that’s also out of the scope of this article.

The investigation

First, on OSB the retry interval of the particular Business Service was decreased from 60 seconds to 10. And the performance increased. Since the retry interval was shorter, OSB does a retry on shorter notice. But of course this did not solve the problem.
As Service developers we often are quite laconical about retries. We make up some settings. Quite default is an interval of 30 seconds and a retry count of 3. But, we should actually think about this and figure out what the possible failures could be and what a sensible retry setting would be. For instance: is it likely that the remote system is out of order? What are the SLA’s for hoisting it back up again? If the system startup is 10 minutes, then a retry count of 3 and interval of 30 seconds is not making sense. The retries are done long before the system’s up again. But of course, in our case sensible settings for system outage would cause delays being too long. We apparently needed to cater for network issues. Read the complete article here.
