j,

First, there's no "l" in HP-UX.

Second, they run on different hardware (with the notable exception of the Itanium Processor Family).

They have some subtle command differences but not much.

HP-UX is heavy duty, 24x7, non-stop, industrial strength. Linux is still trying to achieve that sort of quality.

Hi Jazz,

Pete also forgot to mention that there is also no L in HP-UX!

On a more serious note, there are distributions of linux available for little or no money - which is not the case for HP-UX which must be bought from HP or a reseller and licensed.

regards,

Darren.

Darren,

I used the lowercase version. It probably looks more like an i (eye) or something.

Pete - I knew I should have picked the N! That'll teach me for having such tiny fonts.

Big difference is LVM.

You can use LVM to mirror with HP-UX, which is really important, though you have to buy it. I Don't think LVM is available in the Linux version.

Other topics.

Linux lets you do things with the crontab schedule that is not generally accepted in the Unix community. They are trying to set a standard, but people move their crontabs to HP-UX and are surprised when they don't work.

I think HP-UX, properly patched can not be beaten on reliablity. It scales nicely, I really like it.

Oracle and Red Hat and a few other Linux vendors are working very hard to make Linux World Class with how it runs Oracle's database and applications. Usually it requires more Intel processors to equal the performance of PA-RISC HP-UX and Oracle's licensing runs $40,000-$60,000 per CPU.

It can get pricey FAST!!!

HP-UX has Ignite, probably the best Disaster Recovery/Software Installation tool I've ever used. Linux has mondo and mindi, but I've not tested it. I trust Ignite with my job.

Re: linux & hp-ux differences?

LVM is available in Linux - has been for a couple of years. I think Steven may be referring to the MirrorDisk/UX product that allows logical volume mirroring in HP-UX. That, I don't believe, is available in Linux.

Disposable Servers:

LINUX managers go LINUX because of its cheapness and the term 'disposable server' has evolved because of this. An O/S reinstall is usually the only way to fix problems that evolve from degradation over time.

LINUX O/S Loaders:

On the Intel platform PC firmware is going to be an issue. BIOS is vastly inferior to PA-RISC or SPARC firmware. You can network boot from 'lilo', you need 'grub' while these are firmware utilities in PA-RISC and SPARC. This is why there are so many LINUX O/S loaders like 'lilo' and 'grub'.

IDE vs. SCSI:

IDE is awful. With SCSI you can load your O/S on one SCSI disk and your applications on other SCSI disks, but because of CMOS and BIOS in IDE everything goes on controller 0's master disk. Terrible performance.

Diagnostic Utilities:

Goes along with 'disposable servers' since diagnostics are almost unheard of in LINUX, or at best, they're in their infancy. Red Hat 8 and 9 are just now being released with some basic commands.

And nothing beats LVM for reliability, not even VXVM.
