You Asked


Is it possible for a Solaris NFS to be mounted on a Linux Intel-Based Exadata machine? This approach seems (at least to me) to be alluded to in this section of Oracle Database Backup and User's Guide:

"5.Make the export dump file and the data files to be transported available to the destination host.

You can use NFS to make the dump file and current database files (not copies) accessible. Alternatively, you can use an operating system utility to copy these files to the destination host."

So, instance having to copy the datafiles over to the Exadata machine, how can we use NFS to make the datafiles available to the Linux Exadata Machine? Both our primary and physical standby have mirrored "shadow copy" of their database files, and off this is feasible, it would save “a lot of time” that would normally be needed to copy the database files over to the Exadata machine.

If this is possible, can you at least direct/tell me how this can be done?


and we said...

Yes. I can give you a real example.

At a client, we needed to move from AIX to Linux (which also means an endian change). In the case, all files were housed on NFS (via a NetApp storage device) but NFS is pretty much NFS.

So we

- backup up the AIX datafiles to the NFS share
- ran RMAN convert scripts on them to do the endian switch
- "imported" (aka transportable tablespace) those files into the Linux database

Here's a blogpost I did on it.

and there's lot of info on MOS about how to do it with minimal downtime.

Hope this helps.
