Get starting with RMAN

Backing Up a Database in ARCHIVELOG Mode:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;

Backing Up a Database in NOARCHIVELOG Mode:
RMAN> SHUTDOWN IMMEDIATE;
RMAN> STARTUP MOUNT;
RMAN> BACKUP DATABASE;

make incremental backups of the database:
BACKUP INCREMENTAL LEVEL 0 DATABASE;
BACKUP INCREMENTAL LEVEL 1 CUMULATIVE  DATABASE;//累积增量
BACKUP INCREMENTAL LEVEL 1 DATABASE;//差异增量

incrementally updated backup: //增量更新备份 就是针对copy的增量备份
backup as copy incremental level 0 tag 'ranyu' format '/orabak/%U_%t.cy' database;//做个0及copy备份
backup incremental level 1 for recover of copy with tag 'ranyu' database;
backup incremental level 1 for recover of copy datafilecopy format '/orabak/data_D-ORCL_I-1354688406_TS-

SYSAUX_FNO-2_15on27tp_829497273.cy' database;

Reporting on RMAN Operations：
LIST BACKUP OF DATABASE BY BACKUP
LIST BACKUP BY FILE
LIST BACKUP SUMMARY
LIST BACKUP RECOVERABLE
LIST BACKUP OF DATABASE;
LIST COPY OF DATAFILE 1, 2;
LIST BACKUP OF ARCHIVELOG FROM SEQUENCE 10;
LIST BACKUPSET OF DATAFILE 1;

REPORT NEED BACKUP DATABASE
REPORT OBSOLETE;
REPORT SCHEMA;
REPORT UNRECOVERABLE;//报告不能恢复的

Maintaining RMAN Backups:
CROSSCHECK BACKUP;
CROSSCHECK COPY;
DELETE OBSOLETE;

RESTORE DATABASE PREVIEW SUMMARY;

Diagnosing and Repairing Failures with Data Recovery Advisor：

Recovering Tablespaces:
RMAN> SQL 'ALTER TABLESPACE users OFFLINE';
RUN

SET NEWNAME FOR DATAFILE '/disk1/oradata/prod/users01.dbf'
TO '/disk2/users01.dbf';
RESTORE TABLESPACE users;
SWITCH DATAFILE ALL;   # update control file with new file names
RECOVER TABLESPACE users;
}
RMAN> SQL 'ALTER TABLESPACE users ONLINE';
