Hi,
The guy here
http://rootshell.be/~yong321/freeware/pio1_3_c.txt
wrote a small C prg that easily allows you to see what
processes perform strong I/O's, and to further troubleshoot
eventual waits caused by this process activity. It's ed
me in a few cases to point out database problems.

But this code is only relevant to Solaris operating system:
I'd like to know if you could me to adapt it to
-AIX,
-HPUX, and
-Linux
operating systems...
As you'll see this code rests upon the psinfo files located
in /proc/<PID> directories. Is there a similar (and simple
too) way to get at processes I/O activity within these 3
operating systems as well ?

Thanks a lot !
Regards,
Sp

Not sure about other UNIX's. But now Linux has something equivalent (or
better):
