The content of the three following RHEL 7 courses are already available:

• Red Hat System Administration I (RH124) – v7,
• Red Hat System Administration II (RH134) – v7,
• RHCSA Rapid Track Course (RH199) – v7.

In addition, Allyn Collins from Red Hat gave the following information:

• The RHEL 7 versions of the System Administration III course (RH255), the new Red Hat Certification Lab course (RH300) and the RHCE exam (EX300) will be live on June 30, 2014, allowing RHEL 5 RHCE to re-certify in the 60-day period,
• Recertifying candidates will have 50% off for RHCSA/RHCE courses/exams as previously.

Finally, according to the RedHatCertified Facebook account (https://www.facebook.com/RedHatCertified), Red Hat will provide the Red Hat Certified Engineer (RHCE) Exam on Red Hat Enterprise Linux 6 through December 2014.

While Red Hat System Administration I (RH124), Red Hat System Administration II (RH134), Red Hat System Administration III (RH255) and RHCSA Rapid Track course (RH200) see their content updated, the Red Hat Command Line Administration course (RH190) is stopped, part of it being added in the RH124 course.

In addition, the RHCE Rapid Track course is replaced with the new Red Hat Certification Lab course (RH300) because it is no longer possible to cover all the system administration courses in four days. This latter training allows students to practice in a lab with the help of an instructor before taking the RHCE exam.

With the official release of Red Hat Enterprise Linux 7 happening yesterday, some certification rules are automatically triggered:

• All RHCTs/RHCSAs/RHCEs on Red Hat Enterprise Linux 5 will be expired in 60 days, candidates need to pass both the RHCSA exam (EX200) and the RHCE exam (EX300) to get the RHCE certification again,
• All RHCSAs/RHCEs on Red Hat Enterprise Linux 6 exceeding the 3 year period are expired (the RHCE exam date is the reference if both exams were passed, the date of the certificate of expertise in case one was passed),
• All RHCEs on Red Hat Enterprise Linux 6 or later not exceeding the 3 year period need only to pass the EX300 RHCE to get recertified (no need to pass the RHCSA again).

Today, as previously anticipated 6 days ago, RHEL 7 has been officially released.
It is already possible to download a 30-day evaluation of the distribution on the Red Hat website if you’ve got a Red Hat account or the full DVD iso in case you have an active subscription.

Concerning certifications, the official press release says that “more details about the Red Hat Enterprise Linux 7 training and certification portfolio will be available soon”.

During a face-to-face conversation with a Red Hat official representative, an information slipped: RHEL 7 should be released before the end of June. The still secrete date should be revealed during a webinar around the 10th of June (it should be this one).

Starting from May 15, 2014 it is no longer required to be RHCE to take the following exams:

• Red Hat Certificate of Expertise in Deployment and Systems Management Exam (EX401),
• Red Hat Certificate of Expertise in Server Hardening Exam (EX413),
• Red Hat Certificate of Expertise in Clustering and Storage Management Exam (EX436),
• Red Hat Certificate of Expertise in Performance Tuning Exam (EX442).

Red Hat Certificates of Expertise are now only valid for 3 years. The ones passed before October 1, 2014 will be valid until October 1, 2017.

The Red Hat Certified Architect certification (RHCA) now requires RHCE certification plus success to any five of the following Red Hat exams:

• Red Hat Certificate of Expertise in Hybrid Cloud Administration,
• Red Hat Certificate of Expertise in Hybrid Cloud Storage (EX236),
• Red Hat Certificate of Expertise in Platform-as-a-Service (EX280),
• Red Hat Certificate of Expertise in Deployment and Systems Management (EX401),
• Red Hat Certificate of Expertise in Server Hardening (EX413),
• Red Hat Certificate of Expertise in Clustering and Storage Management (EX436),
• Red Hat Certificate of Expertise in Performance Tuning (EX442),
• Red Hat Certified Virtualization Administrator (EX318),
• Red Hat Certified System Administrator in Red Hat OpenStack (EX210),
• Red Hat Certified JBoss Administrator (EX248),
• Red Hat Certificate of Expertise in Security: Networking Services (EX333)*,
• Red Hat Certificate of Expertise in Directory Services and Authentication (EX423)*,
• Red Hat Certificate of Expertise in SELinux Policy Administration (EX429)*.

*These exams are no longer offered but can still count for RHCA certification.

After passing the five mandatory exams, any new exam passed will add a distinction to the RHCA certification: level I, level II, etc.

If you’ve got a very blur idea about what features the RHEL 7 brings with it, this RHEL 7 review published by QA Ltd (86min) is for you.
This review explores all the main features in detail and explains you what will change.

With systemd, services can be socket-activated, D-Bus-activated or manually started.
This means you have to be very cautious when stopping a service and take extra precaution if you don’t want it to restart!
Previously with RHEL 6, to stop the NetworkManager service for example, you had to type:

# service NetworkManager stop; chkconfig NetworkManager off

In the new RHEL 7 world, you will have to type:

# systemctl disable NetworkManager; systemctl stop NetworkManager

It’s disable then stop and not the other way around!
If you don’t follow this rule, you will be sometimes surprised to see your service still running: it will have been restarted by another process!
This is a true story that happened with the NetworkManager service.
Be assured this will happen again if you are not careful!

If you are working in a RHEL6-Windows environment, Red Hat recently released an update of its Integrating Red Hat Enterprise Linux 6 with Active Directory document, written by Mark Heslin.
In the Red Hat Reference Architecture Series, this paper presents the various solutions in a hybrid environment. For each of the four main configurations considered, it describes the different steps.
If RHEL6-Windows integration interests you, this is a must-read.

As previously announced, Red Hat just released the RHEL 7 Release Candidate.
This version can be downloaded from the Red Hat ftp site.
