Ginny Had A Bright Idea

In the Olden Days before most of us were born, if a woman got a bright idea she got an immediate spanking from John Wayne. Thank goodness John Wayne has stopped doing that, or we wouldn't get to reap the benefits of the research Ginny Henningsen did with Oracle Solaris 11.
When Ginny read about all the different ways to download, install, patch, and manage updates in Solaris 11, she wasn't sure where to start. So she drew on her personal experience, the experience of other sysadmins and systems engineers, the documentation, and the related technical articles posted on OTN.
The result? These three very practical articles.
The SVR4 packaging and patching systems in earlier versions of Solaris were designed by the Chosen for the Faithful. If you loved SunOS you could recite package nomenclature in your sleep and you always, always used the command line. Alas, nobody loves software for its own sake any more. At least, not enough of us do. And so, the latest version of Solaris does away with the mystery, the animal sacrifice, the practice of witchcraft, and the other requirements for mastery of earlier versions. Read how Ginny put away her potions and figured out the best way to use the new tools.
Boot environments in Solaris 11 perform a function similar to Live Upgrade environments in Oracle Solaris 10. Except that they're implemented with ZFS. Which means you can generate snapshots of your boot environments at every point you'd like to record. And the beauty of that is, of course, that you can return to any snapshot of the boot environment that you want to use. In this article, Ginny introduces TimeSlider, shows you how to configure it to take automatic snapshots, and explains how to keep a record of the software updates that have been made to the current boot environment.
Before the Zone there was the Container. And before the Container, the Zone. This is The Way of Software. In her third "Best Way" article, Ginny figures out the best way to manage software updates in Solaris 11 zones which, as you might expect, are different from Solaris 10 zones. After showing you those differences, she shows you how to create, configure, install, and clone a Solaris 11 zone, then how to upgrade both the global and non-global zones. As a bonus, you get to find out what to do if something goes wrong.
We're expecting more "Best Way" articles from Ginny down the road. So read these, try out their recommendations yourself, and tell us what you think.
And don't forget to save the lemur!
