--这个是有pluggable database存在的情况。

RMAN> show all ;

using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name TEST are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
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 RMAN OUTPUT TO KEEP FOR 7 DAYS; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\APP\ORACLE\PRODUCT\12.1.0\DBHOME_1\DATABASE\SNCFTEST.ORA'; # default

--可以发现缺省CONFIGURE CONTROLFILE AUTOBACKUP ON; # default，而在11G以前这个缺省参数是off。
--还多了一行
--CONFIGURE RMAN OUTPUT TO KEEP FOR 7 DAYS; # default

--据说12c没有pluggable database存在的情况下，缺省CONTROLFILE AUTOBACKUP是off，没有测试环境无法测试。

CONFIGURE RMAN OUTPUT TO KEEP FOR 7 DAYS;
这个参数设置了 V$RMAN_OUTPUT保留的天数。
