You can find information about the recommended general database layouts and storage configurations to avoid issues related to disk groups, file types, and tablespaces.
Do not include files from more than one type of SAN file system in your database.
All files making up a database must reside on the same type of file system.
SnapManager requires a multiple of 4K block size.
If you want to register SnapManager backups with Oracle Recovery Manager (RMAN), you must create RMAN-enabled profiles.
The following are some guidelines for volume separation:
Data files for only one database must be in the volume.
You must use separate volumes for each of the following file classifications: database binaries, data files, online redo log files, archived redo log files, and control files.
You do not need to create a separate volume for temporary database files, because SnapManager does not back up temporary database files.
