## (i.e. "can't write a dynamic hotbackup script for raw disk") is untrue.
Ok but in the case when datafile uses symbolic link point to raw device then how this could work?

You would just use the same techniques (i.e. query the data dictionary to generate a shell script) as you would with any other type of datafile... Also, you do not need to "put tablespaces into backup mode and use 'dd'" if you are using RMAN, OPS or not. RMAN was the right idea to start with -- directing toward user-managed backups is a *big* step backward. The MML (media-manager layer) choices vary with the platform. Each platform (i.e. HPUX, AIX, Solaris, Tru64, NT/2000, etc) presents different choices for MML (i.e. Omniback, ADSM, Veritas, Legato, etc). There are several good bulletins on MetaLink (search keywords like "RMAN MML", for example) as well as excellent documentation in the standard docset (search http://docs.oracle.com). Also, the Oracle Press book "Oracle Backup & Recovery 101" is excellent and the O'Reilly book "RMAN Pocket Reference!

You will need to put tablespace in backup mode and use "dd" to copy the appropriate raw device. Note that you can't write a dynamic hotbackup script for raw disk - your script will need to be modified whenever you added a datafile.
