两种方式。
退出：exit 即可。
关闭和启动数据库：
RMAN> shutdown immediate
using target database control file instead of recovery catalog
database closed
database dismounted
Oracle instance shut down
RMAN> startup
connected to target database (not started)
Oracle instance started
database mounted
database opened

跟在sqlplus里面一模一样。
显示默认配置：
RMAN> show all

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN configuration parameters for database with db_unique_name ORCL 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 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 ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/s01/product/11.2.0/dbhome_1/dbs/snapcf_orcl.f'; # default
RMAN>
并不能像sqlplus里面使用 / 。
还可以针对上面列出的配置单独显示：
RMAN> show device type;
RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
RMAN> show channel;
RMAN configuration parameters for database with db_unique_name ORCL are:
RMAN configuration has no stored or default parameters
RMAN>
可以通过configure 对默认值进行更改：
RMAN> configure controlfile autobackup on;
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully stored
