Duplicating a DB with RMAN - and keeping current over days
I have a scenario that I'm trying to see if it will work with RMAN. (9i databases)
I have a database in production. I want to clone it over to another machine with RMAN. But I don't want to open it. I want to keep it current for several days. Then after applying the Incremental backups & logs over several days, open it.
The reason is I have a VERY short downtime window and the database is too big to clone during that window. The idea is that all we'll have to do is apply the logs from the last hour or so during the down time, then we'll be up and running.
I thought about using DUPLICATE, but it opens the database with reset logs. The Docs suggest re-running this to keep it up todate, but that does a complete clone again.
I also thought about using standby, but not sure about it yet.
