Replicated Red Hat Storage Server Volumes provide you with high-availability, when a single server goes down all your data is still there. Even better, if you were using that server to access your data using the native client it will automatically switch over to a server that is still responding. But what if you want to mount the volume while the server you normally use is down?

Why Certify?

The demand for Linux engineers today is growing rapidly with the increase of “cloud” services. More and more organizations want their data to be available everywhere they go with zero downtime to their applications. This kind of demand from organizations requires that engineers know their “stuff” cold. When a web server goes down or a disk fails, you don’t have time to Google for an answer while there is a service outage affecting all of your customers. Becoming Red Hat certified is just one way to set yourself apart when showing potential, or current, employers that you can rise to the challenge.

Red Hat has clearly recognized these types of challenges that engineers and administrators face today when they developed their exams. Instead of the normal Q & A you would expect, these exams are fully hands-on. This lab style exam format helps to set Red Hat apart from other vendors by showing that certified individuals are highly experienced in their roles. For me, having Linux experience is critical to my job and being certified (from multiple vendors) shows expertise to my clients and peers.

Exam Format

The two main Red Hat exams are the Red Hat Certified System Administrator (RHCSA) exam, and the Red Hat Certified Engineer (RHCE) exam. As previously mentioned, each exam is completely hands-on and requires a solid proficiency of Red Hat Enterprise Linux in order to pass. The RHCSA is two and half (2.5) hours long, while the RHCE is two (2) hours.

Converting a web project generated by the JBoss Developer Studio CDI Web Project wizard to a Maven project will give you the power of the Maven build system with its dependency management, build life cycles, and automated JEE packaging abilities. To covert a JBoss Developer Studio web project, follow these steps:

1. Right click on the project name in the Project Explorer tree and select Configure → Convert to Maven Project… In the wizard steps be sure to select WAR packaging.

2. Configure the Java SE 6 compiler plugin so that we can process annotations. Add this to pom.xml file:

<build>
  <plugins>
    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.6</source>
            <target>1.6</target>
      </configuration>
    </plugin>
  </plugins>
</build>
