Re: Q: EXP from AIX and IMP in HP possible?

Actually, you can copy the datafiles themselves from one platform to another, skipping any local LVM headers. Use dd for raw on UNIX or just copy the files from the filesystem.

Once you have all the files in the proper place, including copies of the controlfiles and redo logs, and assuming that you don't want to change file names or path names, its just like starting up after a cold backup.

I use something like this from AIX to AIX, but it should also work from HP to AIX or vice-versa ( adjusting for the differing LVM methodologies from one to the other ).

On the host where you want to create the copy database, execute:

remsh host_where_db_lives 'dd if=/dev/raw_device bs=8192000 | gzip -5' | gzip -d |dd of=/dev/my_new_logical_device bs=8192000

note: the quotes above are very important.

This assumes you are trusted as oracle between these two hosts and that you have a sub 100Mbs LAN or are sending across a WAN. Otherwise, you may not want to filter everything through gzip.

Be very careful with this because you can easily wipe out your "good" database. In fact, I wouldn't recommend doing this at all. You should go ahead and use exp/imp, as this is much easier.
