Oracle put out End of features Notices
Support for the 32–bit only x86 hardware has been removed. Support for running 32-bit applications and libraries will continue.
Support for legacy systems that have included the UltraSPARC I, II, IIe, III, IIIi, III+, IV and IV+ processor architectures (as reported by the Solaris ‘psrinfo -pv’ command) has been removed. All Oracle SPARC Enterprise M-Series Servers and Oracle SPARC T-Series Servers will continue to be supported.
Note: Oracle Solaris 10 will continue to be a supported operating system for these affected platforms as per the current Oracle lifetime support policy.
xVM hypervisor, the Solaris x86 Xen based hypervisor has been removed. Users who want to use an x86 based hypervisor solution can look at Oracle VM Server for x86 or Oracle VM Virtualbox. See http://www.oracle.com/us/technologies/virtualization/oraclevm/index.html
The cacheFS cache filesystem designed to speed up network file system file access for networked computers has been removed. Improvements to NFS have meant that there is less of a need for a cache filesystem.
Trace Normal Form (TNF) tracing, including prex(1), tnfdump(1) and tnfextra(1) has been removed. Instead, use dtrace(1M) for tracing.
Oracle Solaris Containers for Linux applications has been removed. Users who want to run Linux applications in a virtual environment should consider either Oracle VM Server for x86 or Oracle VM VirtualBox. See http://www.oracle.com/us/technologies/virtualization/oraclevm/index.html
The /etc/hostname.<interface> files are no longer supported interfaces for storing persistent network configurations. Use the ipadm(1m) and dladm(1m) commands to configure the IP interfaces persistently.
