On linux uname -p will tell you which processor your kernel is running.

It will run either by default based on the HW

run  isainfo -v to see if anything is running in 64bit mode

#isainfo -b
This shows the number bits in the address space on the instruction set. So, if it shows 64 bit then your machine is 64 bit.
If you do, #isainfo -v
This will show both 64 bit and 32 bit, that can run on your machine. If it also shows 64 bit, then your version of solaris is 64 bit.

Please note that 64 bit machine can run 32 bit applications but NOT vice versa. So it is obvious that 64 bit solaris cannot run on 32 bit machine.

Find where isainfo is located first.
#whereis isainfo
isainfo: /usr/bin/isainfo
#/usr/bin/isainfo -b
