Examples of RMAN duplicate database scripts

I prefer to set the parameters db_file_name_convert and log_file_name_convert whenever possible, to simplify the redirection of restored files.

Here is an example when parameter log_file_name_convert is not set. We are also specifying the auxiliary channels with vendor specific tape settings:

run { 
allocate auxiliary channel t1 type sbt PARMS="BLKSIZE=1048576" maxpiecesize 32G maxopenfiles 64; 
allocate auxiliary channel t2 type sbt PARMS="BLKSIZE=1048576" maxpiecesize 32G maxopenfiles 64;
send 'NB_ORA_POLICY=mypolicy,NB_ORA_CLIENT=myclient-bkp.mydomain,NB_ORA_SCHED=myschedule'; 
set until scn 5886541624244; 
duplicate target database to AUXDB1 
logfile group 1 ('/data/oracle/u01/AUXDB1/redo01.log') size 128M, 
        group 2 ('/data/oracle/u02/AUXDB1/redo02.log') size 128M, 
        group 3 ('/data/oracle/u03/AUXDB1/redo03.log') size 128M;
} 

Another example, when both db_file_name_convert and log_file_name_convert are set.
In smaller environments, you may not need to bother specifying different backup polices etc, you simply specify 'SBT_TAPE' and the

run {
allocate auxiliary channel c1 type 'SBT_TAPE';
allocate auxiliary channel c2 type 'SBT_TAPE';
set until time "to_date('01.05.2014 18:00:00','DD.MM.YYYY HH24:MI:SS')";
duplicate target database to AUXDB1; 
}
