My current project is purchasing:
* Veritas Database Edition H/A for Oracle for Sun E4500s includes File System,
Volume Manager, CVS, and CVS Agent for Oracle. This will enable file system
management with increased performance. This product also seems to provide
the ability for hot and cold backups.

If I use the the above product, it doesn't seem as though the Oracle Hot
Standby feature is necessary to provide a hot backup server. Is this true?
Are both products needed to provide a hot backup server? Thanks.
