The Network Load Balancer is a non-proxy load balancing solution that performs pass-through load balancing of layer 3 and layer 4 (TCP/UDP/ICMP) workloads.

Load balancing is a key component in your cloud infrastructure and plays a pivotal role in the digital experience of your users. As the gateway between users and your application, load balancers enable the availability, scalability, and agility that your business needs in today’s digitally transformed world.

In his article, Gopi covered interesting insights of the Oracle Cloud Infrastructure Flexible Network Load Balancer such as the Pass-through layer 4 (TCP/UDP) load balancing and Scaling network virtual appliances and transparent layer-3 next hop.

Have you ever wondered how to do case-insensitive and accent-insensitive search in Oracle Database? https://devstyler.io/blog/2021/04/28/have-you-ever-wondered-how-to-do-case-insensitive-and-accent-insensitive-search-in-oracle-database/ Wed, 28 Apr 2021 10:32:39 +0000 https://devstyler.io/?p=49269 ...]]> Well, Chris Saxon, an Oracle Developer Advocate for SQL, explains it all. 

Chris Saxon

Most applications store a wide variety of text such as names, addresses, and descriptions. When searching on these values, often you want letters in the values to match the search pattern disregarding the case.

In Chris’ latest post, you can gain more information on how to perform both Case-insensitive search and Accent-insensitive search, how to sort rows regardless of the case or accents and how to define search and sorting roles for a column. Chris also explains how to ignore case or diacritics before Oracle Database 12.2 and how to create indexes for fast searches.

Chris’ job is to help you get the best out of the Oracle Database and have fun with SQL. To help you with this he blogs at ALL THINGS SQL. He also creates videos combining SQL and magic on YouTube at THE MAGIC.

Freedom to Build – Oracle Adds APEX Low https://devstyler.io/blog/2021/04/28/freedom-to-build-oracle-adds-apex-low/ Wed, 28 Apr 2021 09:18:28 +0000 https://devstyler.io/?p=49264 ...]]> Oracle Corporation further demonstrates its commitment to developers by expanding Oracle Cloud Free Tier with two new Always Free services that enable rapidly creating low-code Oracle APEX applications and managing JSON document data. Both services are completely free to Oracle Cloud users for an unlimited time.

Тodd Bottger, а Product Management Director in the Oracle Database team at Oracle Corp, wrote in his latest post more about the new and always free Oracle APEX application development, that will help people and professional developers to rapidly build and deploy low-code apps in Oracle Cloud.

Todd also spoke more about the new always free Oracle Autonomous JSON Database. This is a cloud document database service that makes it simple to develop JSON-centric applications and handle JSON workloads.

Last but not least, Bottger commented on Oracle’s Growing List of Always Free Cloud Services. You can understand more about the Freedom to Build with Oracle APEX applications from here.

Here are the new highlights from Oracle Application Express (APEX) https://devstyler.io/blog/2021/04/02/here-are-the-new-highlights-from-oracle-application-express-apex/ Fri, 02 Apr 2021 12:07:37 +0000 https://devstyler.io/?p=47002 ...]]> Oracle Application Express (APEX) is a low-code development platform that enables you to build stunning, scalable, secure apps, with world-class features that can be deployed anywhere. Using APEX, developers can quickly develop and deploy compelling apps that solve real problems and provide immediate value. 

In this article, we will present you a compilation of the highlights of Oracle APEX from March 2021 by some technical experts and professionals from the field.

Starting with Carsten Czarski’s article about “Synchronizing Parent-Child REST Sources” with APEX 20.2. Carsten’s posting showed how two REST APIs (which model a parent-child relationship) can be synchronized to two local tables. Some PL/SQL code were required. Declarative APEX features were used to the maximum possible extent.  You can check the whole article of Carsten Czarski from here.

On the other side, Monica Godoy examined the “Top 10 Reasons why Oracle APEX is Ideal for Oracle Forms Developers”. Monica noted that Oracle APEX has a number of similarities to Oracle Forms, in both concept and purpose. Hence, this is why many Oracle Forms developers have learned APEX and are flourishing as APEX developers! You can check the top 10 reasons why Oracle APEX is an ideal development platform for Oracle Forms developers from here.

If you need a detailed explanation of the On-premises APEX installations in Oracle Database 21c you definitely have to read Joel Kallman’s article. Joel is a software development vice president. In his article, he gave recommendations, reasons, explanations, meanings and implications. Go and check the whole article from here.

If you want to know more about MLE and the Future of Server-Side Programming in Oracle APEX listen to this article of Salim Hlayel, a principal product manager. Salim noted that the future of MLE has much more to offer for APEX developers. The inclusion of other server-side languages such as Python and the native loading of external NPM libraries will provide huge advantages to our team.

Become Java Certified Developer for $25 Instead of $245 https://devstyler.io/blog/2021/03/22/become-java-certified-developer-for-25-instead-of-245/ Mon, 22 Mar 2021 17:08:40 +0000 https://devstyler.io/?p=45566 ...]]> To celebrate Java’s 25th year, Oracle is offering a huge discount on Java certification: Only $25 for the exam, and the learning pathway (30 hours of educational content) is free! The news broke in the official Oracle Developer Newsletter as it was announced by Alexandra Weber Morales, Oracle Director of Developer Content.

This is also a great opportunity for college students or people just getting into computer science

If the full exam is too difficult, the beginners could try the Java Foundations certification, which is a good introduction that still looks nice on every junior’s resume.

“When I look back, I realize that the process of getting certified made me understand all the exam topics in depth, including reasoning out why and how the language or platform works. The Java Certifications were relevant 18 years back – they are still relevant – recognized and valued by organizations and professionals the world over. These certifications are validated by the industry – creators of the Java language. They help individuals to demonstrate their pro-efficiency with Java. Organizations benefit by selecting from a certified pool to work on their projects”, said Mala Gupta, Oracle Certified Professional (OCP), Java.                

How it works?

The first step is to activate your free learning subscription. After that you’ll have access to the learning materials required to pass the Java SE Developer OCP. This learning path teaches your advanced programming skills.

The second step is to register for your exam for only $25 USD instead of $245.

The limited edition offer ends on April 25, 2021.
