Recently, I been part of one POC where I have learned how we can consume Business Events from Oracle Engagement Cloud.
Oracle Engagement Cloud is a Software as a Service (SaaS) offering from Oracle which provides unified Sales and Service Capabilities, includes sales force automation to manage the full sales lifecycle including leads, accounts, contacts, opportunities, assets, activities, assessments, and forecasts. Leverage content on mobile, the web, and email applications etc.
Beneath the hood, there are several business object e.g. Account, Contact, Plan, Opportunity, service request etc. which form the data model to store data in back-end and exchange data with other systems.
In this blog, I will be simply demonstrating the prerequisite which are required to configure inside Oracle Engagement Cloud and OIC Sales Cloud Adapter configuration.

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 220.127.116.11 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

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 –
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”.

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.
