How Many CPUs? (Itanium)
I've got a dual CPU Itanium server that we use for hosting our Oracle database. It's been up and running fine for quite some time. So well, in fact, that I haven't even looked at 'top' in a while. Recently I needed to look at 'top' and I only see one CPU listed now. CPU0. Is there any other way within HP-UX 11.23 to tell how many CPUs are in the system without having to shutdown to the firmware? I would like to avoid having to boot the box tonight, but if that's the only way, then I'll do that. I don't know how long it's been running with one CPU or if the top display is even accurate. I know I did have an issue at one point where one of the CPUs became "deactivated" and I had to go into the firmware to re-activate it. Not a clue why that happened and I'm hoping that's not what happened this time.

Does anybody know if HP-UX on Itanium always comes with backwards compatibility for PA-RISC applications?
I've heard that there is an emulator called Aries which should do the trick, I just need to know if it always comes as standard with HP-UX Itanium systems.

This is definitely a "stupid" question, but I can't think of anywhere else to ask it, so here goes. My knowledge of CPU history on big iron machines starts with the last DEC Alphas, a short stint with Sun servers, PA-RISC and Itanium, Intel 486s on the desktop before that, and Motorola 68000 CPUs...
