We are going 64-bit for HP but keeping Oracle at 32-bit. We really had no choice for the HP side. We just need the memory that 32 bit could not support. We have 9 K-class servers here that have been running 11-64-bit for quite some time (relatively speaking). But we are getting rid of all our K-class servers. The model we are running have been nothing but trouble. We hate to turn one off because it seems like every time we reboot hardware dies. Other fabs have been having the same issue. So we are going N-class for the database cluster and A-class for the remaining. Since your K-class servers are new they probably don't have the same hardware issues we have. HP even owned up to having issues.

Interesting. We've got a 4-way K570 w/3GB mem that we'll be moving from HPUX 10.20 to HPUX 11.0 this weekend (8 hours of watching tape spin), which means I can FINALLY get us to 8i! YAY!

So, why or why not should one go to 64bit? Here's my perception:

        Pros
        ---------------
        Should be faster (moving 2x as many bits around)

        Cons
        ---------------
        Requires major downtime to go from 32 to 64.
        Patches don't seem to come as quickly as 32bit versions on HP.

        Unknowns (for me)
        -----------------
        How much faster, if at all, and in what areas (mem, I/O, disk)?
        Possible client problems?  Our clients are all 8.0.5 for now.
        Any difference/disadvantage if 3rd party OCI programs are
                not recompiled?

TIA,
