Converting from HPUX 11.00 to 11i

[Joel Shank]

Can anyone tell me how difficult it is to upgrade to 11i from 11.00? Is it as easy as 10.10 to 10.20? Do I have to watch for anything during the upgrade?

Also, from an applications perspective, how does 11i differ from 11.00? Will applications that run fine on 11.00 run the same way on 11i?
Will they have to be re-compiled? Most are MF COBOL programs, with some C.

Thanks for your help :-)

Your first sentence, is a downgrade or moe likely a typo.

11.00 to 11i is a possible upgrade.

You need to check all applications, MF Cobol especially for conversion and compatability issues. MF Cobol 4.1 is no longer supported and DOES NOT work on 11i according to Microfocus. This applies to box set from Microfocus, not anything built into the OS and licensed by HP.

Applications like oracle will need to be relinked.

Some executables will need to be recompiled, some not.

The best path is a cold install of the OS followed by installation of all your applications. This means extended down time unless you have new hardware.

upgrade-ux works about 2/3 of the time according to my lab experience.

Hi


www.docs.hp.com

look at the readme

http://www.docs.hp.com/hpux/os/11i/index.html#Installing%20and%20Updating


Applications are best recompiled but should run on a higher version.

Each compiler is a subset of the next version and there is nothing new while downwards compatibility is a nono due to the compiler being a superset.

I would expect compiled on 11.00 to run on 11.i at the same kernel bit size

Hi Joel,

11i may take little more space than 11.0 for vg00 filesystems. Look at docs.hp.com site and the release notes in there for 11i.

Applications that ran on 11.0 should continue ot run on 11i. However, if this is production system, I would make sure I pre-install 11i on a sandbox, install the application and see there are no issues.

11i offers quite a few dynamic kernel parameters than 11.0. It is also supposed to manager the buffer cache better. You will get JFS version 4 by default with the filesystems so Online Operations work much better than before.

The following release notes may help you to better understand the new features of 11i.

My experience with the 11.0 to 11.11 upgrade has been very good -- as long as /stand and / were not built at the default sizes. If you oversized those filesystem by about 30% above default then the upgrade should go flawlessly. I would certainly have a make_tape_recovery before doing the upgrade. Your COBOL/C should run without modification. In fact, I've moved unmodified object MF/COBOL code from 10.20 to 11.11 without problem.
