Simple OS Version Questions ...

[Terence Burns]

Being new to the site, I don't know much. I have two simple questions:

1) HPUX 10.x is 32-bit and HPUX 11.x is 64-bit ...true or false?

2) If the above is true, is it safe to say that executables for 10.x will not run on a 11.x machine?

Thanks for your time.

10.x is 32 bit. 11.0 can be 32 bit or 64 bit. The underlying hardware must support 64 bits in order to do a 64 bit install. But either way, your 10.x executables will run on 11.0.

Here is where you can read the release notes for 11.0:

Here is where you can read the 64 bit porting guide:

1 - True if your hardware can support 64 bit operation. HP-UX 11.x can be run in 32 bit or 64 bit mode on a 800 series server. 700 series clients are 32 bit only at this time.

2 - Most HP-UX 9.x and 10.x executables should run on HP-UX 11.x, but not all will. You should check with your software vendor (or programmer) to verify compatibility.

Hi,

HPUX 10.2 is 32-bit only. But you have 32 & 64 bit versions for HPUX 11.0

It depends on the h/w you are going to install. If you try to install in any of the latest servers like J5000 (700 series) you can install only 64-bit.

on Old servers like c200 you can install only 32-bit versions of HPUX 11.0

2) All 10.20 executables may not run on HPUX 11.0. Some requires re-compilation
