RMAN> backup as compressed backupset format '/disk2/backup/orcl_%d_%s_%p.bus' database;

 

%d   => sid

%s   => backupset num

%p   => piece

 

 

RMAN> show retention policy;

RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

(delete obsolete시 마지막 한개만 남기고 backupset 과 관련 archive 파일 지우겠다는 뜻)

 

RMAN> delete obsolete;

 

해도 제대로 지워 지지 않을 경우

 

RMAN> crosscheck backupset;

 후 다시 delete obsolete

 

 

 일반적 rman 질의

 [oracle@orcl ~]$ vi b.rcv

backup datafile 4;

list backup datafile 4;

 

[oracle@orcl ~]$ rman target / cmdfile=b.rcv log=a.log append

 

 

 

 

[oracle@orcl ~]$ rman target / cmdfile=showall.rcv log=c1.log

  차후 누가 설정값을 바꾸었을 경우. diff 명령어를 사용하여서 비교 가능.

 

 

[oracle@orcl ~]$ rman target / cmdfile=showall.rcv log=c1.log
RMAN> 2> 3> [oracle@orcl ~]$

      EM 에서 값 변경후

 

[oracle@orcl ~]$ rman target / cmdfile=showall.rcv log=c2.log
RMAN> 2> 3> [oracle@orcl ~]$
[oracle@orcl ~]$
[oracle@orcl ~]$ diff c1.log c2.log
