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.

Is Troubleshooting Important for you ? I hope, the answer is Yes. If that’s the case for you then first thing we need to know where to look for the detailed error message when something going wrong e.g. Gateway server not pooling API configuration from Management tier, while Invoking API end user getting “Internal Server Error”, “Resource not found” etc etc. There could be many types of error but often its hard to find out root cause of exact error.
Recently, I have created an API which was further calling and HTTPS endpoint. While, invoking that API I was getting error “Internal server error”, However, there was nowhere I could easily locate the details error about this problem. I had looked Managed server.log, ManagedServer.out, APICS EDR file and many other files but couldn’t find useful error message related to my error. Later, I found one log file “default.log” which helped me to get root cause of my error. Hence, I decided to compile a list of all logs files, their location and bit of description, so that next time when I hit the some issue, it could be much easier for me to find out root cause by looking relevant log file. This blogs definitely helps to reader as well if they got stuck with API Gateway Error.
Note: The path given in my explanation could be different than your environment but I hope you can very well workout your environment path after looking my sample PATH which I have mentioned in this blog. My base location of installation was “/u01/apics”, the rest PATH should be same in your environment.
Also, before enabling debug/trace severity make sure it’s impact on file size because some of the files start getting thousand of lines of logs once you enabled the debug/trace log severity.
So, here is my comprehensive logs files list, their location and bit of description which you won’t find in Oracle APICS documentation.

In one of my recent Event engagement, I was expected to provision 50+ users in Weblogic. Creating users in Weblogic is not cumbersome process, it’s fairly easy. However, when you need to do in bulk it can take hours.
So, I just came up with simple WLST script which take an configuration file as input which contains all the server credentials required to make connectivity and list of users, description and group name etc and create and delete users in Weblogic.
Note: I have tested this script in Weblogic 18.104.22.168 but it should work in all Weblogic version as long as the beans which I have used inside python not been change in particular Weblogic Version.
This is configuration file which keep server credentials and all users name along with description, group and password.

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

Need to understand how Containers, Kubernetes and the Cloud-Native Landscape fit together?
Organisations are excited about the cloud-native approach as it helps provide parity between development and production environments, adoption of the DevOps framework, and enables software developers to build great products faster.
This new paradigm in application delivery has brought with it much new jargon and tooling – “Containers”, “Docker”, “Kubernetes”, “Container Orchestration”, and “Microservices” are fast becoming the new norm.
Save time and get up to speed on the business value and technical know-how of these contemporary, cloud-native concepts and tools, including:
- CNCF Landscape

I’ve recently been working on a Chatbot demo that can submit orders for souvenirs through Facebook Messenger and updates the Oracle SCM Cloud. We demoed this in Cloud World Sydney and the idea was to be able to have the attendee make an order through Messenger, then receive a QR code to claim their souvenir at the demo booth, where we show that their request had flowed into SCM.
Now the only problem is our environment automatically generates an email notification where the order is submitted. We needed to turn it off otherwise the user would receive 2 emails.

In this blog, we showcase the abilities of Oracle Integration Cloud – Process to be embedded in SaaS applications. This is useful when you need to straddle workflows across systems or when users you need to conduct an approval are outside your organisation. OIC Process is extremely powerful for application extensions, providing capabilities to deliver embeddable UIs for Forms and Task Lists as HTML5 files that can be inserted in ANY application, Oracle, non-Oracle and even on-prem. We are using Oracle Service Cloud to showcase this. Service Cloud is a Service Request SaaS CRM, typically utilized by Contact Centres. Since only Contact Centre users have access to Service Cloud, what if you need information from another department, such as Field Services/Billing or even another organisation?
