Red Hat Software Collection (RHSCL) 2.3 brings new rh-perl524 collection.
It includes Perl 5.24.0, which provides a number of bug fixes and enhancements over the previously released rh-perl520 Software Collection. The details about the changes can be found in 5.22.0 perldelta and 5.24.0 perldelta. The new collection adds package rh-perl524-perl-App-cpanminus, which contains the cpanm utility for getting, extracting, building, and installing modules from the Comprehensive Perl Archive Network (CPAN) repository.

With the release of Red Hat JBoss Developer Studio 10.2, it is now possible to install Red Hat JBoss Developer Studio as an RPM. It is available as a tech preview. The purpose of this article is to describe the steps you should follow in order to install Red Hat JBoss Developer Studio.
Red Hat Software Collections can make your life as a programmer or admin immensely easier.
Like death, taxes and zombies, dealing with different versions of software is something you just can’t avoid. It’s a nasty but necessary fact of life.
Traditionally, when developers and system admins grapple with this issue, they have to sacrifice something. If you want to run the latest and greatest version of a web app, it might not support users with outdated browsers. If you install the newest beta release of Python so you can test development code, it might break Python scripts written for older releases. If you have a system with multiple users, you might want a different version of Ruby over another. And so on.
Software Collections provide a solution to conundrums like these. They let you have your cake and eat it, too.
In other (more technical) words, Software Collections make it possible to have multiple versions of the same software on the same system. You use a simple tool to tell the system which version to activate as needed.
If that sounds awesome, it is. Keep reading for a more detailed explanation of how Software Collections work, and an overview of using them on your Red Hat system.

Red Hat JBoss Core Services Collection is a group of common services that are critical for application developers. The services included change as new services and projects are added over time, but the idea is to include common, developer-friendly projects under a single subscription. The collection makes it much easier for developers to access these services.
The launch of the Core Services Collection includes services that focus on three areas: web servers, security, and monitoring.
There are six components available in the launch of Core Services Collection:

MongoDB has evolved into one of the most popular open source “NoSQL” databases—so-called because they dispense with the tabular storage schema of relational databases like MySQL and Postgres. NoSQL databases offer a variety of advantages in many cases
The biggest advantage is that MongoDB databases don’t require developers to define schemas before adding data to a database. Instead, they use a flexible document-based model, similar to Python dictionaries or Ruby hashes. With MongoDB, you don’t need to spend time creating tables before you can process your data. That makes the NoSQL approach ideal for situations where you don’t know how much data you have to handle, what form it is in, or how quickly it is going to move around.
There’s a lot more to say about what makes MongoDB, and NoSQL in general, a better fit for some situations. (I could also write a great deal about when not to use NoSQL—and that’s important, because despite NoSQL’s current trendiness, it’s not better in all contexts.)
But that’s all fodder for a separate blog post. For now, let’s move onto the meat of this post, which is how to install MongoDB on Red Hat Enterprise Linux (RHEL) in order to take advantage of NoSQL databases.
