Configure Letsencrypt SSL Certificate in Weblogic 12c

Who doesn’t like the security. This is one of critical element of our IT Infrastructure. Recently I was doing one POC and got requirement to setup a valid SSL certificate in Weblogic. However, since it was just an POC we were not having any valid SSL certificate issued by some Certificate Authority. Later, I came across for one website called https://letsencrypt.org/ . Let’s Encrypt is a free, automated, and open certificate authority (CA). they give people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, and its free, yes you heard correctly It’s FREE !!!. You don’t need to pay them at all. So if you need a valid SSL certificate for your POC or even for Production environment you can get one from them. Although their certificate comes with 3 month validity, so while using for Production environment user need to keep renewing with them with simple automated process.

In this blog we will be learning how we can generate letsencrypt SSL certificate, what’s prerequisite to get the certificate and setup that certificate in Weblogic server to enable SSL communication.

So, Lets move on. We will be doing below stuff in sequence –

Get a registered domain name (This required while generating SSL Cert)
Install Certbot ACME Tool and Apache HTTP Server
Generate Letsencrypt SSL Certificate
Configure Letsencrypt SSL in Weblogic Identity Store

‘API life Cycle is invalid!’ Error for Oracle API CS API’s

Hi, just thought to post the solution for this error, when I hit this error, searched all over internet couldn’t find any specific blog describing possible cause of getting this error while invoking an API.

Let me give some background. I have created an API using Oracle API Platform Management Portal and when I tried invoking that API using google postman tool I was getting below error –

postmane

This was a silly mistake but worth highlighting. When we create API definition in API Management portal there is tab page “API Implementation” which has configuration field “API Request” where we need to define the API endpoint URL where consumer of this API will send input request. While I was declaring that portion I have given this URL “api/medrec”.

Oracle API Platform Cloud Service – Installation Steps of Gateway Node

In this blog I am going to document the Oracle API Platform Gateway Node (Version : 18.1.3) Installation steps which is one of the critical components of API Platform Cloud Service.

Oracle provides API Platform Cloud Service as a foundation product for API Management that comprises the Full API Lifecycle, encompassing the complete API Design & Documentation, API Security, Discovery & Consumption, Monetization, and Analysis etc.

Oracle API Platform comprises 3 major components as stated below to serve specific purpose-

Management Portal – This is used to create and manage APIs, deploy APIs to gateways, and manage gateways, and create and manage applications. You can also manage and Deploy APIs and manage gateways with the REST API.

Developer Portal – Application developers subscribe to APIs and get the necessary information to invoke them from this portal.

Gateway Node – This is the security and access control run-time layer for APIs. Each API is deployed to a gateway node from the Management Portal or via the REST API.

In addition to above, Oracle also offer Oracle Apiary to quickly design, prototype, document and test APIs.

Below is the high level architecture diagram of API Platform.
