Part 2 of Ginny Henningsen's series on Best Practices in Software Management for Oracle 11 Express addresses how Oracle Solaris 11 Express uses automated snapshots to deliver Time Slider services, a new feature in the GNOME desktop. Time Slider enables users to take periodic snapshots of the active Boot Environment (BE), capturing the software state at regular intervals. This approach might prove useful if you forget to explicitly create a BE when you update software, she suggests.

In Part 2 of her series "Software Management Best Practices for Oracle Solaris 11 Express," "Automating ZFS Snapshots and Tracking Software Updates," Ginny Henningsen describes how Oracle Solaris 11 Express uses automated snapshots to deliver Time Slider services, a new feature in the GNOME desktop. Using Time Slider, she writes, users can take periodic snapshots of the active Boot Environment (BE), capturing the software state at regular intervals, which can prove useful if you forget to explicitly create a BE when you update software.
BEs, Henningsen goes on to explain, a built-in safety net when to be used in making software changes, much like Live Upgrade environments in Oracle Solaris 10. In Oracle Solaris 11 Express, the root file system is implemented using Oracle Solaris ZFS, so BEs are basically Oracle Solaris ZFS snapshots that are readable/writable and activated for booting. This underlying technology enables users to periodically generate snapshots of BEs just like you can take a snapshot of any Oracle Solaris ZFS volume.

As the Oracle white paper "Distributed Development Using Oracle Secure Global Desktop" explains, the Oracle Product Development IT Group (Oracle PDIT) employs Oracle Secure Global Desktop as a gateway to development
environments used by Oracle’s software development teams working worldwide on Oracle Fusion, Oracle E-Business Suite, and various other Oracle applications. These software developers use Oracle Secure Global Desktop to access X Windows applications (xterm, fvwm, gnome) running on Solaris OS or Linux servers in the data center, giving them access to various graphical development tools such as Oracle JDeveloper, as well as systems running Microsoft Windows. Oracle PDIT has thousands of concurrent users spread across multiple Oracle Secure Global
Desktop arrays around the globe. By this means, Oracle is able to provide its software development teams the access they require to their specific developer environments from any location, reliably and without performance degradation. In addition, administrators can centrally administer access to individual developer environments across multiple locations worldwide.

Jim Laurent reports that Solaris 11 Express is available for download and demonstrates
in a video tutorial how to install that O/S as a Virtual Machine with VirtualBox.
Solaris 11 Express allows you to preview the technologies that will be delivered in Solaris 11 next year. In this video tutorial, Jim will take you through the steps to install and configure Solaris 11 Express using Oracle's free Type 2 hypervisor, VirtualBox. VirtualBox can be downloaded for free and is available for MacOS, Solaris, Linux and Windows Platforms.
Solaris 11 Express is binary compatible with Solaris 8, 9 and 10 and is supported on SPARC as well as X86 chip sets. It is a fully virtualized operating system to include virtual networks, zones and file systems (ZFS).
