Abstract[edit]

The following articles presents several ways to determine the system Kernel Width.

Using the getconf command[edit]

You can use getconf command.

# getconf KERNEL_BITS
64

Using the file command[edit]

You can check the current vmunix kernel file using the file command.

# file /stand/vmunix
/stand/vmunix:  ELF-64 executable object file - PA-RISC 2.0 (LP64)

Using the print_manifest[edit]

You can use the bundle Ignite-UX "print_manifest" command to obtain the OS mode.

# /opt/ignite/bin/print_manifest | grep "OS mode"
    OS mode:            64 bit

Using SAM Interface[edit]

SAM interface can also be used to obtain the information.

Select Performance Monitors -> System Properties -> Operating System and check the OS Kernel Width: value.

NOTE: HP-UX 11i v2 and HP-UX 11i v3 is only supported on 64 bit platforms, then on this Operating Environments the kernel will always run in 64 bit mode.
