Configure Custom Domain in Private Space : CloudHub 2.0

 With CloudHub 2.0, applications are deployed in public spaces or private spaces. Private space isolates the applications deployed, and different network customizations can be done within the private space. Earlier in CloudHub 1.0, DLB used to be configured to balance the incoming load along with configuring the custom/vanity domain instead of using * We can configure vanity/custom domains in the private space, avoiding accessing the applications through the default * domain. Configuring the custom domain will require the public certificate and the private key as a prerequisite. Generating the self-signed public certificate and the private key For simplicity, we will try to create certificates for the wildcard domain. To generate the self-signed public certificate and private key, we will require OpenSSL . 1. Create a config file as below, name it config.cfg , and change the values as per the domain details.

Experimenting Recursion in DataWeave - Fibonacci Series

  In various programming languages, recursion is a process in which a method or function calls itself to simplify a complicated problem. Understanding recursive solution sometimes become difficult. Let's try to solve a mathematical problem through recursion with a twist by using DataWeave . The Fibonacci series is a generic use case that recursion can solve. This is a very generic question in programming interviews. Photo by Natalya Letunova on Unsplash What is Fibonacci Series? A Fibonacci series is a set of integers starting with 0 followed by 1, and a series continuing with the sum of the preceding two integers in the sequence. For example, F n =0,1,1,2,3,5,8,13,21,34... Mathematically, F 0 =0 F 1 =1 F n =F (n-1) + F (n-2) Now transforming the above logic in the form of a recursive function to find the nth digit in the Fibonacci series. DataWeave Recursive Function: %dw 2.0 output application/json fun fib_r(n)= if (n&l

Connect Free Oracle Autonomous Database from MuleSoft

 A database is the most commonly used backend in the integration world. We often build a lot of integrations with databases (be it as a source or target system). Likewise, working on a proof-of-concept, we always find it hard to have a database that we can use on a local machine or on the cloud. If we install a database on a local device it will consume a lot of resources. Not only that connecting from a cloud integration platform i.e. MuleSoft cloudhub is always tricky. Oracle has an always free-to-use Autonomous Database instance available on the cloud with limited features but is really a powerful database to use. We would say, it is one of the best suitable for doing proof of concepts and validation before working on an actual use case. We thought of giving it a try to connect MuleSoft to the Free version of the Autonomous Oracle database. We created a free trial account for Oracle and an always-free autonomous database instance. Once we have the instance created, we can connect

Break it! Fix it!

 One of the items on my bucket list was to do a live stream. This item always went to procrastinate bucket. There were multiple reasons for it. First, the most apparent one is "FEAR", fear of doing something new that I never tried before. Then comes the second hurdle, okay now I have decided I will do it but what topic shall I pick.  Now whatsoever topic you choose, you will see someone in some part of the world has already delivered that topic. Okay, now for instance topic is also decided, and now how to engage the audience when you cannot see them. And after getting answers to all the questions, what if you are stuck and things are not moving in the middle of the stream? The damn tense situation you are in. So, in this blog, I will discuss my first-time experience on a live stream. First-time experiences always hold importance in your life and are it good or bad are always remembered. I did my first live stream on the MuleSoft community twitch channel and Twitter 🥳🥳🥳🎉

[Mule 4]Catch numeric exceptions inside DataWeave

 Numbers are a simple data type, but become complex in real-time integration transformation scenarios. Number data type, we consider number system in base 10 and perform all kinds of arithmetic operations e.g. +, -, *, / etc. We do this starting in childhood: multiply two numbers, divide one number by another, or add two numbers. Now, where is the tricky part 🤔?  Let’s start with, various tricky aspects and possible remedies to these. This article is published on the MuleSoft Community  LinkedIn page.
