Re: rman question

Joan,
I don't know about about cold backups but I have done this successfully with hot backups. What you can do is restore your hot backups ( could be old ones ) and do a point in time database recovery using rman 'duplicate database' command. It 's fairly straightforward.

Janardhana,

Thanks, another question is that on same production machine we have FM online production instance and reporting instance. We refresh reporting database everynight. (shutdown production, cp datafiles..) Can I use rman to restore all datafiles and redo files to reporting database and recreate control file to rename the reporting database? How rman deal with redo files if we use cold backup? (you know, I can do OS image copy for those files) Is that a tag name can include all the datafiles, control files and redo files image copies)?
