RMAN-06183: datafile or datafile copy prod_data_01.dbf (file number 9) larger than MAXSETSIZE

Action:

1) Verify the RMAN backup script and check the backup setsize set properly.

RMAN backup setsize should be more than the max(size) of datafiles in the database.

run { 

allocate channel dev1 type 'SBT_TAPE';

allocate channel dev2 type 'SBT_TAPE';

allocate channel dev3 type 'SBT_TAPE';

allocate channel dev4 type 'SBT_TAPE';

sql 'ALTER SYSTEM SWITCH LOGFILE';

backup 

        full

        filesperset=30   

        setsize=20000000    ( make sure this value is more than the max datafile size in db).

        format='fulldata_%d_%s_%p_%t' 

        database ;

}

2) RMAN> show all;


CONFIGURE MAXSETSIZE TO 30720 M;

Here we go so we have the max file size limit of 30g where as my file size is around 32 g.
 So to fiz this...

RMAN> CONFIGURE MAXSETSIZE clear;
