Oracle is adding a secret recipe to all their Cloud Services with a nice touch of Machine Learning. This makes it possible to have the new series of “Autonomous” Cloud Services that are self-driving, self-healing and self-securing. Stay tuned, because we are going to keep listening a lot about them.
In this blog I am going to show you how to provision an Autonomous API Platform environment and then provision and register an API Gateway, running on a separate Oracle Linux VM on IaaS.
This is a graphical view of what I will be doing in this blog:

The importance of application development is going beyond IT, helping organisations build out their core value, and innovating their business models to stay competitive. With modern application development platforms, organisations can rapidly build solutions that help to innovate how they operate and serve their customers.
Modern application development platforms enablement organisations to develop and deploy applications in the cloud that support business agility which has the added advantage of significant cost savings.
In this workshop, you’ll see applications being built using a variety of modern application development technologies and principles.
In this session we will cover:
- Data samples to available datasets with RESTAPIs
- User experience via development tools (web,HTML5, mobile, bots)
- Blockchain enabling critical elements
- Integrating applications, supporting modern application development
- Blending real-time external data with machine learning and autonomous datasets
Optional Hands-on Session
At the end of this workshop, we’ll be running a hands-on session and you will need to bring your Wi-Fi enabled laptop and mobile phone with you.
Register now to avoid disappointment as places are limited.

We have covered multiple blogs on how to use Terraform to help automate the provisioning of environments and treat your Infrastructure as Code. Until now, for PaaS stacks, we have used Terraform together with Oracle PaaS Service Manager (PSM) CLI. This gives us great flexibility to script our own tailored PaaS stacks the way we want them. However, with flexibility comes responsibility, and in this case, if we choose to use PSM CLI, it’s up to us to script the whole provisioning/decommission of components that make up the stack. As well as what to do if we encounter an error half-way through, so that we leave things consistently.
A simpler way to provision PaaS stacks is by making use of Oracle Cloud Stack, that treats all components of the stack as a single unit, where all sub-components are provisioned/decommissioned transparently for us. For example, Oracle Integration Cloud (OIC) stack, is made of Oracle DB Cloud Service (DBCS), Integration Cloud Service (ICS), Process Cloud Service (PCS), Visual Builder Cloud Service (VBCS), IaaS, storage, network, etc. If we use Oracle Cloud Stack to provision an environment, we only have to pass a YAML template with the configuration of the whole stack and then, Cloud Stack handles the rest. Pretty awesome huh?
Similarly, as we have done in the past, we are going to use a “Build Server”. This will be used as a platform to help us provision our PaaS stacks. When provisioning this “Build Server”, I will add all the tooling it requires as part of its bootstrap process. For this, I am using Vagrant + Terraform, so that I can also treat my “Build Server” as “infrastructure as code” and I can easily get rid of it, after I built my target PaaS stack.
This is a graphical view of what I will be doing in this blog to provision an OIC stack via Cloud Stack:

Polls. Surveys. Live Voting. It’s all about gathering live responses in any venue: conferences, concerts, classrooms etc.. There’s a proliferation of tools (including online tools) to create and conduct polls: “Download the mobile app today and be ready for your next interactive class or event tomorrow“.
For those who don’t know the difference between a poll and a survey a poll is used to ask one simple question while a survey is generally used to ask a wide range of multiple questions. … How tedious are those questions?
If the point is obtain information do we want to bother our attendees with 10 questions (that they are not likely to answer) or do we want to ask 1 small, simple and quick question? Well, being an attendee myself I think polls are way more powerful and effective than surveys so I thought a simple responsive Polling Web App was a good excuse to put my hands on Visual Builder and get familiar with the Visual Applications. This post assumes you’re familiar with Visual Builder Cloud Service – if you’re not reading Carlos’ latest post Teaching How to Get Started with Oracle Visual Builder 2.0 is certainly a good idea.

In this blog, I am going to show you how quickly you can use data in an existing Excel spreadsheet with multiple tabs and use it to auto-generate API-based microservices using Oracle Visual Builder. Then, we are going to consume our own generated APIs via a rich set of HTML5 components.
For demonstration purposes, I am going to upload an Excel spreadsheet that contains 3 tabs (Order, Buyers and Products). This is a simple way to play with master/detail records. Feel free to use the same spreadsheet as an initial demo vehicle to auto-generate REST APIs and build Web Applications.

Data Warehouses have been around for a long time and they bring multiple benefits, but these also come at a cost. Some of the associated challenges that are easily identified when talking about traditional Data Warehouses include:
- Complexity and Expensive
- Inability to manage data and user growth
- Hard to deploy and maintain
Oracle Autonomous Data Warehouse aims at easing these challenges with the ability to:
- Provision a data warehouse in as little as 15 seconds.
- Full automation of management of the Data Warehouse
- Instant scaling with zero-downtime
- Automated Tuning
- Migration tools, e.g. Redshift
In this blog, let’s show can easily we can provision a new Oracle Autonomous Data Warehouse, load data into it and run some data visualization on top.

Oracle API Platform’s API Implementation has two service naming convention 1) API Request 2) Service Request.
API Request – is the endpoint to which users or applications send requests for your API.
Service Request – is the URL at which your back-end service receives requests.
In this blog we are going to discuss what are the additional configuration we need to done inside API Platform Gateway Server while invoking a HTTPS Service Request URL.
Since, its HTTPS URL obviously there is associated SSL cert with that URL which is signed by Certificate Authority.
Recently, I have been doing one POC where I was invoking a Service Request HTTPS URL but it was not working and later found out it’s because of associated SSL certificate was not configured in Weblogic JKS Keystore.
Before, I get into detailed solution, let me tell you bit more about problem. At very initial stage when I tried creating an API which is in-turn calling an HTTPS service request, it was failing while invoking that service from rest POSTMAN tool and was getting “Internal Server error” as per below snap.
