Oracle Solaris 11.2 was released just after Ops Center 12.2.1, and I've seen a few questions about when we'll support it, and to what degree.
The first answer is that Oracle Solaris 11.2 is now supported for most features in Ops Center. You can manage it, install it, update it, create zones on it - basically, anything you can do with Oracle Solaris 11.1, you can also do with Oracle Solaris 11.2.
The caveat to that is that the features introduced with Oracle Solaris 11.2, such as Kernel Zones, are not yet officially supported through Ops Center. We're working hard on adding that support right now.
