I know the steps to create physical standby database on file systems and I have already used it and works properly.
On other system with SUN Cluster, I need to install Oracle 10g RAC and use Data Guard to align database on Disaster & Recovery site.
Primary database is created on several raw devices and my problem consists in copying a cold backup (image copy) of all the raw devices used in primary database on the Disaster & Recovery site that has the same disks structure with the same (names and dimensions) raw devices created.
The use of file systems on secondary site using DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT is impossible (customer request) and I don't know if using the dd command (how, what bs, and so on) can resolve the problem.
There is another way?
Can sameone help me?
Thanks

Hi,
If you don't want to use dd, use RMAN to make datafile copies.
BTW: DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT work perfectly well with databases on filesystem and RAW volumes.
Best regards.

Ciao Frank,
DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT are used on logical standby DB, and I want to realize a physical standby DB. So, I don't need to use them.
I'm not familiar with RMAN but I try to use it.
If you have time to continue to help me, you could give me a short procedure to backup&restore DB using RMAN. Otherwise thanks very much for your help.

Hi,
You mean DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT are only applicable to physical standby databases.
See section "Preparing to Use RMAN to Create a Standby Database" in the Data Guard Concepts and Administration Guide.
Best regards.
Frank
