From time to time, I often hear of stories that it's harder to find administrators who have a solid knowledge of Oracle Solaris when compared to Linux. Oracle Solaris can be an intimidating operating system to come to terms with for those who are used to dealing with Linux on a daily basis, particularly if they've had previous perceptions of what it would be like or former experiences with much, much older versions of Solaris. With Oracle Solaris 11 development, one of the primary goals was to greatly modernize the operating system and make it easier to use, remove some of the uneccessary differences between the two operating systems, and remove some of the frustrations that people have had. I believe we've done exactly that with the introduction of Oracle Solaris ZFS as the default root file system, the Image Packaging System (IPS) and much more familiar installation experiences with the LiveCD and interactive text installer. It's now even easier to approach Oracle Solaris, install it into a virtual machine and give it a spin!
One of the help guides that I've recently written is a mapping guide between Red Hat Enterprise Linux 6 and Oracle Solaris 11. Essentially for each general technology area, I list of the main features of Oracle Solaris 11, their advantages and how the command lines and configuration files map between the two operating systems - whether it's between RPM and IPS, KVM and Oracle Solaris Zones, Upstart and the Service Management Facility (SMF). It's designed to give administrators who are familiar with Red Hat Enterprise Linux a first step for where to go to get more information. So, if you're struggling with trying to get started with Oracle Solaris 11, look no further.
