Oh! Oracle Database Cloud, you beauty!

No, I am not a DBA, installing and setting up database on my laptop takes me atleast a day or two. So I was skeptical when I first opened the Oracle Database Cloud's service console. But I have to say Oracle Database Cloud Quick Start guide is just what you need.

Here is a short summary of tasks and how much time it took
  1. Creating a public-private key pair using Puttygen : 5 mins
  2. Creating a service instance : 10 mins.
  3. Waiting for it get in "active" state : ~15 mins.
  4. Enabling Network Access : 5 mins
So, all the above steps and ~35 mins I have a Database instance up-and-running. All is left for me to do is add a new user and define some tables for my frontend or middleware applications.

Oracle Cloud services constantly proving, how easy for just "anyone" to start using technology. User friendly user interfaces, very informative usage guide.

Kudos Oracle!

First of all, let me start with a very basic statement, about security, it doesn't depend on your Webservice type, be it REST or SOAP, your design decisions depicts whether they can be made secure or not.
In this example blog, I will use "Micro CRUD services for Oracle Database Cloud" APIs and implement (read attach) Passport's "local" authentication strategy, to make them secure.

What is Passport JS? (from Documentation)

Passport is authentication middleware for Node. It is designed to serve a singular purpose: authenticate requests. When writing modules, encapsulation is a virtue, so Passport delegates all other functionality to the application. This separation of concerns keeps code clean and maintainable, and makes Passport extremely easy to integrate into an application.

Chatbots and Oracle Cloud Services

Thanks to Oracle A-Team, I had a chance to work with Chatbots.
3 pure NodeJS applications, on couple of Oracle Cloud platforms and Facebook messenger, and my chatbot was running.

Let me explain, the architecture a bit. To start with, following is the simple representation of how it works.

Exception Handling in ADF

This blog will give you an overview on how you can successfully deal with unhandled Runtime exceptions in an ADF application.

This will give you an idea of:
How to catch the unhandled exceptions.Write a separate log file with stacktrace and thread dumps.Redirect the user to an static error page
#1. Catch unhandled exceptions : 

Create a class "MyExceptionHandler" which extends : Override handleException() method.

public void handleException(FacesContext facesContext, Throwable throwable, PhaseId phaseId) throws Throwable {
        // this method is going to create a separate file with stacktrace and thread dumps
        // redirect to error page

 Create a folder "services" inside : ViewController\src\META-INF and then create a file named "".
In the file, add the absolute name of your custom e…
