How to determine if HP-UX uses a 32-bit kernel or 64-bit kernel

Troubleshooting


Problem

This technote explains how to establish if an HP-UX® 11.x kernel is 32-bit or 64-bit capable in order to determine which version of IBM® Rational® ClearCase® to install.

Resolving The Problem

  1. Run getconf KERNEL_BITS on the system in question. The output, either "32" or "64", corresponds to 32-bit or 64-bit kernels, respectively.


  2. Check the vmunix file for the following entries:

    #file /stand/vmunix
    /stand/vmunix:  PA-RISC1.1 executable
    ---> 32-bit
    /stand/vmunix:  ELF-64 executable object file ---> 64-bit


  3. Check the System Administration Manager (SAM) as follows:

    Click Performance Monitors > System Properties > Operating System and check OS Kernel Width: <value>
