Home -> Community -> Mailing Lists -> Oracle-L -> RE: 9i RMAN configuration setting
RMAN doesn't allow you to configure a different default value for maxsetsize
for each channel. You can configure maximum piece sizes for each channel as
seen here:
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT
'D:\oracle\oradata\testing\1\%U' MAXPIECESIZE 100 M;
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT
'D:\oracle\oradata\testing\2\%U' MAXPIECESIZE 400 M;
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
However this doesn't restrict RMAN from putting 2 100MB backup set pieces on channel 1 and 2 400mb backup pieces on channel 2.
The bottom line is that I don't think there is a way to limit a channel so that only x amount of data is going to go to it during a given backup.
Of course, I've been wrong before so someone correct me if I am this time! :-)

Hi,
Does anyone know how I can specify in RMAN the size of the backup data files
to be copied to each channel? For eg. if I have a 500MB database and would like to backup 100MB to channel 1 and 400MB to channel 2, how can I configure that?
Thanks.
