Why should I upgrade from HP-UX 11.00 to HP-UX 11.11 ?

[GIRIJA SWAIN]

Hi,

I have 8-way N-class servers running HP-UX 11.00 used as Iplanet webservers, and java based application servers. These are in dual node Mc Service Guard ver 11.09. I want to upgrade the OS to 11.11, but need to know, what tangible benefit one will expect out of this. Any discussion, case study or whitepaper will be helpful.

PATCHES to KNOWN security, network, kernel, and IO vulnerabilities.

Remember what happend to M$ crap Saturday? That was because they failed to PATCH their servers.

Hi Girija,

11i has more dynamic kernel parameters. Depending on the version of 11i you buy, there will be some softwares like apache, prm , serviceguard etc., packaged with the OS.

Frankly, I can't think of a definitive reason to upgrade - the differences are subtle.

The main thing is that doing it now when you can plan it at your leisure is a lot better than waiting until HP obsoletes 11.0 and then having to rush. I've been gradually moving to 11i for just that reason.

11i(11.11) is more robust, more secure and more reliable.

It will cost you some time to make the upgrade but these benefits make a great OS(11.00) an even better OS.

As far as actual path to get there, don't run the migration process, go for cold install. With Service guard, you should be able to get away with taking the time. The success rate on cold installs is better than that for upgrades.

If you use a database, Asynchronous IO in the kernel (KAIO)

The SMP (scalable Multi processing) is supposed to be better.

I also believe multiplexing of IO cahnnels

Depending on type (enteprise, base ..etc..) you can use VxVM

Thank you all for your suggestions. I agree on the point of FIX for known security issues in 11i. But my problem is to convince the developers with this. Is there some benefits like performance enhancement, stability, scalability ?

[John Bolene]

stability is found with the new dynamic kernel parms starting in 11.11 and continuing in 11.22

If you think you are going to go to 11.11, then consider just going directly to 11.22

And these are all called 11i.

[Patrick Wallek]

John - 11.22 won't run on a PA-RISC box. 11.22 (aka 11i v1.6) is for Itanium machines only.

[Martin Johnson]

You should also look at the products you are running on your system. Some of the latest releases may require 11i.

HP has mentioned in the release notes of OpenView Operations (OVO, aka VPO/ITO) the next major release will not be supported under 11.0.
