Throughout April, Oracle ACEs from all around the world shared insights, tips and tricks and knowledge in more than 350 blog posts. Before this month is over, we wanted to highlight some of them for you to read and enjoy, focusing on Linux, LiveLabs, OCI, Terraform, APEX, and much more.

 

With the recent shift in the CentOS ecosystem, many users are considering migrating to alternative distributions. Oracle Linux, known for its stability, reliability, and enterprise-grade support, emerges as a viable choice for those seeking a CentOS alternative. In this guide, we’ll walk you through the process of migrating from CentOS 7 to Oracle Linux seamlessly.

Often when working with Exadata, there is a need to review the Stroage or Cell Server.  Since customers cannot SSH to the storage server on ExaCC/ExaCS, Oracle has provided the ExaCLI utility, exposing a few select metrics for monitoring and managing the Exadata Storage Server.

I’ve written a few blog posts about the new Select AI feature on the Oracle Database. In this post, I’ll explore how to use this within APEX, because you have to do things in a different way.

Following is a quick article that I prepared for providing the data security, high availability and disaster recovery solution all at once for a mission critical Oracle Data warehouse environment. Below, you will find Oracle Advanced Security, Oracle RAC , Golden Gate, Dataguard and other related features and solutions of Oracle all at once, integrated together, put into the context and proposed together to be in place for securing the data, making it high available and protecting both the data and the services from disasters. Features / Solutions given here can be used in different contexts (for instance: Golden Gate can be used for data integration) as well, but here we are in the scope of data security, high availability and DR, so I will not get into that.

This post will show how to use NVL in SQL query while using DB Adapter in Oracle Integration Cloud. We have below query as an example in which we are filtering on object type and getting count of each object type.

Hello, Oracle aficionados and functional consulting experts! Are you searching for that next big enhancement to elevate your Oracle Fusion HCM suite, especially around the Oracle Recruiting Cloud module? Well, the introduction of version 24B brings with it a fantastic new feature that’s set to revolutionize your recruitment approach: REPORTING FOR OUTBOUND MESSAGES.

Here I’m exploring how to control the basic network level resource security accesses. In AWS there is a concept called Security Groups. In OCI Oracle Cloud the similar concept is called Network Security Groups, also there is a little bit less powerful concept called Security Lists. A good imprevement with Network Security Groups over Security Lists is that in rules you can refer to other NSGs, not only CIDR.

There are many ways to integrate data between two systems. One way to start a lively conversation / fight between two developers is to ask them how they would move some data between system A and system B.

 I wanted to bring to your awareness this capability offered by Oracle LiveLabs Home (oracle.com).  Oracle LiveLabs gives you access to Oracle’s tools and technologies to run a wide variety of labs and workshops using an Oracle tenancy. There’s extremely good content for Developers, DevOps, Data Engineers, Architects and Data Scientists (including content around data lakes, data warehouses, analytics, ML, AI, etc.), particularly in, but not limited to, the OCI space.

I was architecting an APEX extension for an Oracle EBS customer where there was a need to call some standard APIs. These took a little while to run, and as the customer was using an APEX version prior to 23.1 we decided to submit these processes as concurrent programs.

I write and speak a lot about technology, but a personal touch and experience can be nice and interesting sometimes too. This personal touch is telling the journey of how an introvert person like me became a public speaker, and I hope you get some inspiration out of it, maybe taking your first step to speaking in public.

These instructions apply to new installations, as well as upgrades. You can perform a silent installation from the command console if the system has no X-Windows interface or to perform an automated installation. Silent installations can ensure that multiple users in your organization use the same installation options when they install your Oracle products.

Welcome back! Just a quick warning, this is going to be a biased post. Oracle EPM reporting is my sweet spot and where I focus my consulting work. I’ve known the Oracle EPM reporting team for many years and I speak to them regularly. It’s a fun group!

Learn how to add a global search to your Oracle APEX app that searches through all your data and navigation entries.

In the vast and intricate world of enterprise databases, where data is more than just information—it is the lifeblood that powers decisions, strategies, and ultimately success—speed is everything. At the heart of this relentless pursuit for swiftness lies a factor so fundamental yet often overlooked: the speed of light. It might seem like an abstract concern, nestled comfortably in theoretical physics discussions rather than IT department and architecture meetings.

Being a part of the Oracle ACE program has been one of the most rewarding experiences I’ve had in my professional career. As a community, we’re passionate about technology in general, and Oracle’s specifically, and how we can share what we’ve learned and give back to our community. However, one of the best aspects of the program is that it recognizes that personal growth is not limited to a singular realm or outlook.
