Part 1: Solaris 11.2 Highlights in 6 Minutes or Less
Highlights contd.,
Package related ..
Minimal Set of System Packages
For the past few years, it is one of the hot topics -- what is the bare minimum [set of packages] needed to run applications. There were a number of blog posts and few technical articles around creating minimal Solaris configurations. Finally users/customers who wish to have their OS installed with minimal set of required system packages for running most of the applications in general, can just install solaris-minimal-server package and not worry about anything else such as removing unwanted packages.
# pkg install pkg:/group/system/solaris-minimal-server
Oracle Database Pre-requisite Package
Until Solaris 11.1, it is up to the users to check the package dependencies and make sure to have those installed before attempting to install Oracle database software especially using graphic installer. Solaris 11.2 frees up the users from the burden of checking and installing individual [required] packages by providing a brand new package called oracle-rdbms-server-12cR1-preinstall. Users just need to install this package for a smoother database software installation later.
# pkg install pkg:/group/prerequisite/oracle/oracle-rdbms-server-12cR1-preinstall
Mirroring a Package Repository
11.2 provides the ability to create local IPS package repositories and keeps them in synch with the IPS package repositories hosted publicly by Oracle Corporation. The key in achieving this is the SMF service svc:/application/pkg/mirror. The following webpage has the essential steps listed on a high-level.
How to Automatically Copy a Repository From the Internet
Another enhancement is the cloning of a package repository using --clone option of pkgrecv command.

Network traffic diagnostics:
A brand new command, ipstat(1M), reports IP traffic statistics.
# ipstat -?
Usage: ipstat [-cmnrt] [-a address[,address...]] [-A address[,address...]]
[-d d|u] [-i interface[,interface...]] [-l nlines] [-p protocol[,protocol...]]
[-s key | -S key] [-u R|K|M|G|T|P] [-x opt[=val][,opt[=val]...]]
# ipstat -uM 5

Up until 11.1, it is not so straight-forward to figure out what process created a network endpoint -- one has to rely on a combination of commands such as netstat, pfiles or lsof and proc filesystem (/proc) to extract that information. Solaris 11.2 attempts to make it easy by enhancing the existing tool netstat(1M). Enhanced netstat(1M) shows what user, pid created and control a network endpoint. -u is the magic flag.
# netstat -aun <-- notice the -u flag in netstat command; and User, Pid, Command columns in the output

[x86 only] Memory Access Locality Characterization and Analysis
Solaris 11.2 introduced another brand new tool, numatop(1M), that helps in characterizing the NUMA behavior of processes and threads on systems with Intel Westmere, Sandy Bridge and Ivy Bridge processors. If not installed by default, install the numatop package as shown below.
# pkg install pkg:/diagnostic/numatop
Performance related ..
This is a grey area - so, just be informed that there are some ZFS and Oracle database related performance enhancements.
Starting with 11.2, ZFS synchronous write transactions are committed in parallel, which should help improve the I/O throughput.
Database startup time has been greatly improved in Solaris 11 releases -- it's been further improved in 11.2. Customers with databases that use hundreds of Gigabytes or Terabyte(s) of memory will notice the improvement to the database startup times. Other changes to asynchronous I/O, inter-process communication using event ports etc., help improve the performance of the recent releases of Oracle database such as 12c.
Miscellaneous ..
Java 8
Java 7 is still the default in Solaris 11.2 release, but Java 8 can be installed from the IPS package repository.
eg.,
# pkg install pkg:/developer/java/jdk-8 <-- Java Development Kit
# pkg install pkg:/runtime/java/jre-8 <-- Java Runtime
Bootable USB Media
Solaris 11.2 introduces the support for booting SPARC systems from USB media. Use Solaris Distribution Constructor (requires distribution-constructor package) to create the USB bootable media, or copy a bootable/installation image to the USB media using usbcopy(1M) and dd(1M) commands.
Oracle Hardware Management Pack
Oracle Hardware Management Pack is a set of tools that are integrated into the Solaris OS distribution, that show the existing hardware configuration, help configure hardware RAID volumes, update server firmware, configure ILOM service processor, enable monitoring the hardware using existing tools etc., Look for pkg:/system/management/hmp/hmp-* packages.
Few other interesting packages:
Parallel implementation of bzip2 : compress/pbzip2
NVM Express (nvme) utility : system/storage/nvme-utilities
Utility to administer cluster of servers : terminal/cssh
