Upgrading

Marty Metras — Mon, 25 Jul 2005 13:10:53 GMT

We needed to upgrade to Oracle92 on an rp7400 with HPUX 11.0.
Oracle92 requires patches of one of them are PHKL_18543. After dealing with this patch on the rp2450 causing us to reload the OS I have some questions that you may help with.
This is a Production box (rp7400) so I have limited time to do any thing.
Can 11.0 be upgraded to 11.11 without losing the Apps? (Oracle8i, and Powerhouse)
Meaning what would be lost doing an upgrade versa doing a new install of 11.11 where I would have to reload all the Apps.
If I could do an OS upgrade a then apply the patched Oracle92 needs for 11.11 then I may be able to avoid the PHKL_18543 patch.
The PHKL_18543 stopped us from re-compiling the kernel on the rp2450 and would not remove or re-install. We did a new install on the rp2450 and then things went well. This was our standby/test server. The rp7400 needs to be in production so... we you get the idea.

Could I have your thoughts?

Marty - your program will probably be fine. I've run the same version of Oracle Apps on both (by cloning the Applications) HPUX11 and HPUX11i with no interoperability problems at all. The key word is probably - you need to do this first on a test machine. If you're not changing architecture (like going from 32 bit to 64bit), then the application is really not going to be your problem - the O/S upgrade itself will be. Make sure you've got your software licenses ready, you've got your kernel settings documented, disk systems documented, etc.

the problem is not Oracle or Powerhouse.
The Problem is the Patch PHKL_18543.
We are testing Oracle92 and PH843d while runing Oracle8i and PH823d7 on the test server with no problems on the rp2450.
It is the patch-from-@#$% that scares me.

I have been reading through the Forum and it looks like the PHKL_18543 Patch problem is when you try to re-install it.
The patch set I have to load has PHKL_185433 required by most of then. When I create the depot and load the patches will it just skip this patch?
Installing patches is not one of my strong skills.

Sorry Marty - HPUX 11.0 was too long ago for me to remember or retrieve any stats re: that patch. But *it is* time to do that upgrade you're considering.

You ABSOLUTELY DO NOT want to FORCE a reload of PHKL_18543. If the patch is already installed on the system, and is also in a depot to be installed, it will be SKIPPED by swinstall.

Just make ABSOLUTELY SURE you do NOT have the option to reinstall files selected.

The reinstall is what causes problems. You NEVER want to reinstall PHKL_18543.

I agree with you on upgrading to 11i.
We have this time window right now where we can only do the Oracle92 upgrade.
We can schedule the OS upgrade on a holiday weekend.
I checked onre on the patch and found it only re-installing it that is causing the problems. So we will try loading the patches without re-installing PHKL_18543.
The other server it got re-installed in 2003 when we did not know better. THe other server had the new 11.11 install last monthe because of the patch.
I was a little nervous because of it.
Thanks for your input John.
