Re: what is the difference between HP-UX & RHEL?

Sounds like a test question or homework question:

1) One is made by HP, the other Red Hat
2) One is proprietary, the other based on open-source
3) One runs on PA-RISC and Itanium architecture servers, the other mostly on x86 based servers.
4) One uses 'swinstall' to install (some) software and patches, then other yum.
5) One is a whole lot older than the other.

HPUX kernel: /stand/vmunix
RHEL kernel: /boot/vmlinuz

Re: what is the difference between HP-UX & RHEL?

Hi Seenivasan,

1)In HP Unix u cannot customize according to us requirement but in Red Hat Linux u can customize.
2)In HP Unix best solution for OS and other backup Ignite Ux, such solution is not there in RHEL
3)In HP Unix for installation of patches and other software swinstall is used, total diff in RHEL, 3 step install in RHEL ./configure,make and make install and tar ball install.
4)Boot process is totally diff in both HP Unix n RHEL.
5)In HP Unix its fileset, patches, depot and patch bundle but in RHEL its RPM.

Hope this solves ur query.

Hi seenivasn,

One more and major point I want to highlight, Boot process of HP Unix and RHEL both are different.

Re: what is the difference between HP-UX & RHEL?

Vishnu,

from customization i suppose you mean you can make your own rpm file install it on all your machine according to your need.

But in HPUX its not possible.

Anyways, HPUX is much more stable and have better support than RHEL.

Re: what is the difference between HP-UX & RHEL?

Hi Duncan,

Hope ur query is resolved by Kapil's comment I mean to say the same, and one more is that u can compile the kernel in RHEL an not in HP Unix.

Yes Kapil I do agree HP Unix is much more stable and have better support than RHEL.

"from customization i suppose you mean you can make your own rpm file install it on all your machine according to your need.

FALSE: You can create your own so called software "depots" (the equivalent of rpms). see swpackage and other sw toolz.

"and one more is that u can compile the kernel in RHEL an not in HP Unix."

Because there is really no "regular" need sirs. Just like in RHEL, how often do you really need to compile your kernel these days? Everyhing is modularized so no need to wholly re-compile the kernel.

Re: what is the difference between HP-UX & RHEL?

Back to question, Difference between RHEL and HP-UX:

HP-UX:
- Very Proprietary - runs only on the Sunset CPU (Itanium) as PARISC marches on to legendary history.
- Very conservative but stable (slow adoption of recent OS innovations)
- runs on expensive HW
- license and system support costs are high
- simplest among the UNICES to administer
- complete partitioning continuum (and now supports live partition migration)
- continued to be used in Tier 1 "Mission Critical Applications"
- Mature - over 25 years old.

RHEL:
- Open Source (aka "Free")
- Runs on the widest array of CPUs and Hardware including the Itanium System (but only up to RHEL 5.5 - after which RHEL ceases to support the Itanium system)
- Most conservative Linux Distribution - hence the most Stable
- Significant Lower TCO compared to HP-UX but RAS (reliability, availability and scaleability) now at par or even exceeds HP-UX (per my experience)
- Newer X86 HW now exceed the performance and efficiency of UNIX RISC based systems
- Support can be "challenging" from the vendors BUT "Community Support" is top notch.
- ISV Support is at parity with UNIX
- Administration could be complex (due to the many ways of doing things and the number of tools available) - but is otherwise an easy transition for UNIX administrators.
- core Linux kernel is around 20 years old. Redhat Distribuition is over a decade old and the most prevalent of all Linux Distributions.
- RHEL is the "foundation" of many other Linux distributions and so called Appliances and turnkey systems.

Re: what is the difference between HP-UX & RHEL?

Other Differences:

1) RHEL is supported on x86/64, IA and IBM Power6 architectures
2) HPVM provides virtualization of the servers in hpux. In Linux, Citrix to be used to create a virtual infrastructure
3) PRM (Process Resource Manager - a tool to control the amount of system resources that processes use) feature of HPUX is not available in Linux
4) There are Differences in Package management, software update, supported file systems, System administration etc

Re: what is the difference between HP-UX & RHEL?

Hi,

Since the two runs on completely different architectures, I would say that this question has not much sense. I prefer to list the commands which are identical on both platforms. These are base commands which aren't directly related to any hardware-specific things. E.g. think of the following:

ntp
date
tar
cpio
sh
ksh


These were only an example, and you must look at the man page of the commands as besides the main usage they can have some special parameters which are only there on a specific platform.

Regards,
Viktor

Re: what is the difference between HP-UX & RHEL?


btw, on HP-UX you can find the GNU tar under the name gtar. Both do the same, but gtar supports also files larger than 2Gbytes.

Unless this has changed on 11.31, you have to install Gnu tar yourself. It does not come with the OS.

The HP-UX native tar can handle files up to 8 GB.

Re: what is the difference between HP-UX & RHEL?

Differences - My 5:
1.) HW Platforms (1 Platform versus a myriad for Linux)
2.) Security (NSA approved SELinux versus none on HP-UX)
3.) Scaleability (1024 cpus for Linux, ??? for HP-UX)
4.) OpenNess - HP-UX is closed source, RHEL is open source
5.) Clustering Options (5 for Linux with 2 free, only 2 for HP-UX - SG and Veritas)

Core UNIX COmmands -- ther are hardly any difference.


And clarification on:
"2) HPVM provides virtualization of the servers in hpux. In Linux, Citrix to be used to create a virtual infrastructure"
Linux has the richest "partitioning" schemes in the history of all OSes -- there is vMware(itself Linux based), KVM, vBox, Xen, etc, etc.

"3) PRM (Process Resource Manager - a tool to control the amount of system resources that processes use) feature of HPUX is not available in Linux" - and may I ad PSETS."

True - but this is rather insignifcant already as process binding and affinity is possible too on Linux.
