Currently, the only platform capable of supporting the 64-bit Solaris operating environment is an UltraSPARC system. You can verify whether a system is an UltraSPARC system by using the following command:
$ uname -m sun4u |
If the output of the uname -m command is sun4u, then the machine is an UltraSPARC system.
If you are running the Solaris 7 release, you can verify this by using the psrinfo command:
# psrinfo -v Status of processor 0 as of: 02/10/98 14:25:55 Processor has been on-line since 01/30/98 15:10:29. The sparcv9 processor operates at 168 MHz, and has a sparcv9 floating point processor. Status of processor 1 as of: 02/10/98 14:25:55 Processor has been on-line since 01/30/98 15:10:33. The sparcv9 processor operates at 168 MHz, and has a sparcv9 floating point processor. |
If the processor type is sparcv9, the platform is capable of running the 64-bit Solaris operating environment. This test does not work on previous versions of the psrinfo command, where all platforms report the less precise sparc as the processor type.
