How do I determine my solaris system is running a 64 bit kernel?

[petulia3478]

The solaris operating environment can run in 64bit and 32bit. 64bit can only run on 64bit hardware, but the 32bit can run on both 32bit hardware and 64bit hardware.

To check which your operating system support run the following:

$ isainfo -v
64-bit sparcv9 applications
32-bit sparc applications

To check which mode your current kernel is running in, run the following command:

# isainfo -kv
64-bit sparcv9 kernel modules
