Solutionsame product on HP as on Sun?
400 GB, what kind of connection do you have, gigabit?
If it is the same product, export the database to a filesystem, ftp/rcp the file from sun to hp.
How fast, depends on your network, below is a test i did for a large file.
49535.57 Kbytes/s 1000mb
10780.27 Kbytes/s 100mb full duplex
HTH,
Robert-Jan

Re: Migrating Solaris Oracle to HP-UX Oracle
We could use some more details, such as:
* Will you be copying over a network or utilizing some other means, such as tape?
* How fast is the network link between the boxes?
* How fast are all drives involved?
* Will the Oracle datafiles suffice, or must you use transportable tablespaces, or exp/imp?
* Do you care about the time it will take to configure the database on the new server once it has been copied?
You can perform some basic benchmarking on both systems to get some of these values.

Re: Migrating Solaris Oracle to HP-UX Oracle
Does this sound like a good plan of action?

Re: Migrating Solaris Oracle to HP-UX Oracle
The default filesystem type on Solaris is UFS, HPUX uses VXFS.
what are you using on your solaris server?

Re: Migrating Solaris Oracle to HP-UX Oracle
solaris 9 example below with VXVM
root# df -k | grep PXXT | grep d01
/dev/vx/dsk/prd01/poradata-prbt-d01 7323693 5511781 1445728 80% /app/poracle/oradata/PXXT/d01
root# fstyp /dev/vx/dsk/prd01/poradata-pxxt-d01

Re: Migrating Solaris Oracle to HP-UX Oracle
Are you going to do a "whole" database export, or a schema at a time?
As a suggestion, to gain time, I've done the schema at a time version, so as to gain concurrency.
First do sys, system, then go back and export all of the base schemas.
Then to go to each schema for the application(s), then export the users schemas.
Then, you write a script to load the base sys,system in the first step. Second step is for all of the base products. Third step is to begin running (like 10 or 12 processes wide) application schema loads. And lastly load the user schemas 10 or 12 wide concurrently as well.
Then start working on your invalid objects and problems.
Naturally, you'll want the new database patched to EXACTLY the same level as on the Solaris server before you begin the loads.
Of course, you'll do this in test plenty enough times to where the whole process is HIGHLY repeatable, and you've got your timings down.
Don't forget to create (from your timings estimates) a fallback plan. That is, at what time during the weekend, if you're not done, you start putting the system back to the Solaris Server. Remember, the definition of a non-failure for the weekend is that, after it's all over you're still "up" - ON EITHER PLATFORM. A definition of success would be that you've made it to the new system before the drop-dead time designated for cutover.
