Below error i got while taking RMAN backup:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup plus archivelog command at 07/12/2021 03:29:07
RMAN-06183: datafile or datafile copy +ORA_DATA/wwibetest_bosqeumcsdb/datafile/undotbs1.779.1077535587 (file number 3) larger than MAXSETSIZE

Finding and solution:

RMAN> show all;

using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name WWIBEMCS_BOSQEUMCSDB201 are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ‘/backup/oracle/WWIBEMCS/rman/WWIBEMCS_autobcf_%F’;
CONFIGURE DEVICE TYPE DISK PARALLELISM 4 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT ‘/bck/oracle/%d/rman/%d_%Y%M%D_%u_s%s_p%p’;
CONFIGURE MAXSETSIZE TO 30 G;
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM ‘AES128’; # default
CONFIGURE COMPRESSION ALGORITHM ‘BASIC’ AS OF RELEASE ‘DEFAULT’ OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/wwi/wwdb/db/oracle/product/11.2.0.4/db_1/dbs/snapcf_WWIBEMCS.f’; # default

RMAN> CONFIGURE MAXSETSIZE TO 35 G;

old RMAN configuration parameters:
CONFIGURE MAXSETSIZE TO 30 G;
new RMAN configuration parameters:
CONFIGURE MAXSETSIZE TO 35 G;
new RMAN configuration parameters are successfully stored

RMAN> show all;

Now I ran the RMAN backup it went successful.
