Migration to 11i
we are going to migrate a lot of HP servers from hp-ux 11.0 or 10.20 to 11i. Most of them have Oracle databasees up and running (different versions, at least 8.1.7).
Is there any documentation which tells me what is needed for such an migration ?
Thanks in advance,
Christiane Wilken

Re: Migration to 11i
till now i haven't heard of successful migration from 10.2 to 11.0 or to 11i.
(even i tried and failed). Better way is backup the database. do the cold install of OS which gives you the cleaner environment and retrieve the database from backup.

Re: Migration to 11i
See the "Installation and Update Guide" at:
http://www.docs.hp.com/hpux/os/11i/index.html
Also, most everyone will tell you that you're better off doing a cold-install rather than an upgrade, especially when transitioning from 10.20.

Re: Migration to 11i
thanks for all answers !
Unfortunately my question was not clear; of course we are doing an cold installation of 11i. What I would like to know is, if there is any hint on wich patches (for instance) are needed for which ORACLE version; if there is anything we need to think of by duming the database, reinstalling ORACLE and importing the dump.
Any ideas ?
Thanks again,
Christiane Wilken

Re: Migration to 11i
Your Oracle installation documentation for HP-UX will also list any required OS patches required for your version of HP-UX.

Re: Migration to 11i
The docs posted are great, I'll add some practical experience.
1) Forget in place mirgration. If the move is 32 bit to 64 bit for example the oracle database will have to be installed from scratch and the data migrated either through database cloning or export/import
2) Designer Repository will require a clean install of an empty Repository followed by a migration of the Repository data from old system to new.
The good news is, if your oracle datafiles(non-repository) are on an external disk array, you can get away with installing the correct oracle versions on the new system and then transfer control of the virtual/physical disks to the new system.
If you follow the install guide for Oracle the database server installation is a breeze. It takes 20 minutes on an L2000 dual 550 MHz processors with 2G of RAM.
Gosh, I love new hardware.

Re: Migration to 11i
Before I try to shaw my gem of wisdom ;-) let me be sure we are clear...
You have 10.2 and 11.0 HPUX running Oracle Databases.
You are looking to upgrade to HPUX 11i.
I have migrate from 10.2 up to 11 (HPUX 11i doesn't support Oracle Apps 10.7).
I bought a new server. Installed the database files there. And exported/ imported my database in. I was running the June 2002 HP patch set. Ran fine. No problems.
I applied 1-2 additional patches that were docuemnted on the Oracle CD docuemntation/ Readme.
Note: You MUST install new Oracle Database files if moving off of 10.20 ... the object files changed and Oracle was re-compiled.

Re: Migration to 11i
Apply the latest Gold Base Bundle (Sept 2002) and tune the kernel according to the Oracle install guide,
Working sample:
dbc_max_pct 25
max_thread_proc 256
maxdsiz 0X040000000
maxdsiz_64bit 0X080000000
maxfiles 1024
maxfiles_lim 2048
maxssiz 0X008000000
maxssiz_64bit 0X40000000
semmni 4096
semmns (SEMMNI*2)
semmnu (NPROC-4)
shmmax 0X60000000
shmmni 800
