The nature of symbolic links in UNIX is that they
are aliases for files. That's all. Why should it make a
difference?

Ok but in the case when datafile uses symbolic link point to raw device
then how this could work?

This answer (i.e. "can't write a dynamic

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" will be useful during
implementation...

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.
