Answers:

1. vmstat -P
2. % grep mem /var/adm/messages
3. # uerf -R -r 300 | head -20 | grep physical
4. Look at the boot listings in the error log or /var/adm/messages
        files.
5. Run the sizer command with the appropriate option to print
        the memory size.
6. Write a program using the getsysinfo(2) call and code to
        get the amount of memory.
7. Use dbx print the value of physmem and then multiply by
        the pagesize.
8. Run wc(1) with the -c option on /dev/mem. Somewhat CPU
        intensive and may trigger parity errors on system with
        parity memory. It is much safer on systems with ECC
        memory.
9. ...this has been answered before, and you will receive answers
