Re: Rman, Duplicating without set untill.... & cloning with

Ruth,

  When I startup nomount my clone, no files exist, except the init.ora. I then duplicate using:

run {
set until time "to_date('040120020214','mmddyyyyhh24mi')"; allocate auxiliary channel ch1 type disk; set newname for datafile 1 to '/u03/oradata/BSCSD/system01.dbf'; ...yadda yadda...
duplicate target database to BSCSD
logfile

group 1 ('/u03/oradata/BSCSD/redo1a.log','/u04/oradata/BSCSD/redo1b.log') size 25m,
group 2 ('/u03/oradata/BSCSD/redo2a.log','/u04/oradata/BSCSD/redo2b.log') size 25m,
group 3 ('/u03/oradata/BSCSD/redo3a.log','/u04/oradata/BSCSD/redo3b.log') size 25m;
}

  The manual states that duplicate creates the control files. Can you tell me more about creating the controlfiles in noarchivelog?

Thanks,
Jay

Make sure you build the controlfiles on the clone with noarchivelog. That will keep you from having the problem of set until time.

I think your theory is correct. I have the same experience, I have to use SET UNTIL, otherwise RMAN complains about the archivelogs. Oracle 8.1.7 on IBM AIX.

So if you are on a remote system, it will be looking for data in the current redo logs (or logs that were archived since the backup), which it can't access. Oracle claims that RMAN will restore the last backup, but I think it is trying to bring the duplicated DB in sync with production.
