If you have 11.11, here is the fix:

Fixed is [PHNE_28895/PACHRDME/English] for 11.11

If you are on 11.0, the patch is:
should be PHNE_28538.

The error you faced was when a 32bit server talks with a 64 bit server, because there occur some mismatch in the casting of the types.

anyway, transferring oracle data file with rcp is not a good practice, i suugest you to go with ftp, it's more stable.

Massimo,
What are the worries about rcp? I stopped using ftp years ago in favor of rcp ( and the whole r suite)

My backup procedure uses rcp each evening for backup, all new instances are created based on this. If I'm doing something risky, I need to rethink.
Can someone point me somewhere to research the issues with rcp?

using any of the Berkeley commands is not generally secure. You have to setup host.equiv or ~/.rhosts files, and these are not secure. You should be using ssh and scp, the replacement for rcp.

[preface]
It's just my opinion

There are many issues with permission/ownership with the r-commands, even if properly patched;some version of rcp (ex 32bit) do not work with files bigger than 2G.

However, each solution, if properly tested, is good.

If you are able to do restore from the copied oracle data files, no worry.

But for large transferring of such big files, ftp is more reliable and faster.

Once again, it's just my opinion.
