How To Determine If The Solaris Kernel Is 32- Or 64-bit
Most Solaris recomended patch clusters come in either 32- or 64-bit versions. How do you find out which one is appropriate for your platform? Use the isainfo command.
$ isainfo -b 64 $
The -b option prints the number of bits in the address space of the native instruction set. In this case, 64 bits.
$ isainfo -kv 64-bit sparcv9 kernel modules $
The -k option prints the name of the instruction set used by the operating system kernel components, i.e. sparcv9; -v provides more detailed information, i.e. 64-bit sparcv9.
