If your system is already installed with the Oracle Solaris 11 OS, you must upgrade it to the OS version that is associated with the Oracle VM Server for SPARC 3.4 software. See Oracle Solaris OS Versions. For complete Oracle Solaris OS upgrade instructions, see the Oracle Solaris 11.3 Information Library (http://docs.oracle.com/cd/E53394_01/).
The Oracle VM Server for SPARC 3.4 software is installed and enabled by default when you install the Oracle Solaris 11.3 SRU 8 OS.
If your control domain runs a version of Oracle VM Server for SPARC software prior to 3.3, you must first remove the threading property setting from all domains. See How to Remove the threading Property.
The threading property was removed from the Oracle VM Server for SPARC 3.3 release. Therefore, before you upgrade from an Oracle VM Server for SPARC version prior to 3.3 to Oracle VM Server for SPARC 3.4, remove the threading=max-ipc property setting from all domains.
If you do not remove this property setting, only one virtual CPU per core remains after the ldmd daemon is restarted and the whole-core constraint is lost.
primary# ldm set-dom threading=max-throughput domain-name
primary# ldm set-core n domain-name
