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! :-) RF Robert G.

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. elain RMAN configuration parameters are: CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default CONFIGURE BACKUP OPTIMIZATION OFF; # default CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default CONFIGURE DEVICE TYPE DISK PARALLELISM 2; CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'D:\oracle\oradata\testing\1\%U' MAXPIECESIZE 50 M; CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT 'D:\oracle\oradata\testing\2\%U' MAXPIECESIZE 50 M; CONFIGURE MAXSETSIZE TO UNLIMITED; # default CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\ORACLE\ORA92\DATABASE\SNCFTEST.ORA'; # default _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: elain he INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
