Raw to UFS

[netbar]

I have been tasked with migrating a database from raw partitions to UFS.

I do not want to use an export/import as this will take too long.

I was thinking that I could do something with the unix dd command: e.g.
dd if=/dev/vx/rdsk/datadg/datab068 count=25601 of=/spdata/volufs/dbb068 bs=4096

dd if=/dev/vx/rdsk/datadg/datab067 count=25601 of=/spdata/volufs/dbb067 bs=4096

where count= the number of blocks from dba_data_files.


This appears to work on a small test system.

Can anyone think of any hairy areas or gotcha's using this method!


Thanx in advance..

With the dd command you can take offline backups in an Oracle Parallel Server Enviroment. I have tried it, it works.
