Oracle RMAN备份实战

模拟数据库备份计划(Rman)：
数据库周期：
周一0级备份，周二、周三2级备份，周四1级备份，周五、六、日2级备份。
归档备份周期：
每小时备份一次
脚本如下：

启动归档

[root@cjcos01 ~]# mkdir /rman/{db,arch} -p
[root@cjcos01 ~]# chown oracle.oinstall /rman -R
[root@cjcos01 ~]# su - oracle
[oracle@cjcos01 ~]$ sqlplus / as sysdba
SQL> alter system set log_archive_dest_1='location=/rman/arch';
SQL> alter system set log_archive_format = "cjcpdb_%t_%s_%r.arc" scope=spfile;
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;
SQL> archive log list;

创建测试数据

SQL> conn cjc/***
SQL>
CREATE OR REPLACE PROCEDURE test_pro is
begin
  for i in 1 .. 10 loop
    insert into t1 values (i, to_char(sysdate, 'yyyy/mm/dd hh24:mi:ss'));
    commit;
  end loop;
end;
/

周一:0级备份

###0_rmanbak.sh begin### 
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
export ORACLE_SID=cjcdb01 
rman target / log=/rman/db/0_rmanbak.log <<EOF 
run{
allocate channel ch1 type disk maxpiecesize 1000M;
allocate channel ch2 type disk maxpiecesize 1000M;
backup incremental level = 0 
filesperset = 32
format '/rman/db/lev0_%d_%T_%U.bak'
skip inaccessible  database
include current controlfile 
tag '0_rmanbak_cjcdb' ;
release channel ch1;
release channel ch2;
}
EOF
exit 
###0_rmanbak.sh end###

周二、三：2级别备份

###2_rmanbak.sh begin### 
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
export ORACLE_SID=cjcdb01 
rman target / log=/rman/db/2_rmanbak.log <<EOF 
run{
allocate channel ch1 type disk maxpiecesize 1000M;
allocate channel ch2 type disk maxpiecesize 1000M;
backup incremental level = 2 
filesperset = 32
format '/rman/db/lev2_%d_%T_%U.bak'
skip inaccessible  database
include current controlfile 
tag '2_rmanbak_cjcdb' ;
release channel ch1;
release channel ch2;
}
EOF
exit 
###2_rmanbak.sh end###

周四：1级备份

###1_rmanbak.sh begin### 
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
export ORACLE_SID=cjcdb01 
rman target / log=/rman/db/1_rmanbak.log <<EOF 
run{
allocate channel ch1 type disk maxpiecesize 1000M;
allocate channel ch2 type disk maxpiecesize 1000M;
backup incremental level = 1 
filesperset = 32
format '/rman/db/lev1_%d_%T_%U.bak'
skip inaccessible  database
include current controlfile 
tag '1_rmanbak_cjcdb' ;
release channel ch1;
release channel ch2;
}
EOF
exit 
###1_rmanbak.sh end###

周五、六、日：2级备份

###2_rmanbak.sh begin### 
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
export ORACLE_SID=cjcdb01 
rman target / log=/rman/db/2_rmanbak.log <<EOF 
run{
allocate channel ch1 type disk maxpiecesize 1000M;
allocate channel ch2 type disk maxpiecesize 1000M;
backup incremental level = 2 
filesperset = 32
format '/rman/db/lev2_%d_%T_%U.bak'
skip inaccessible  database
include current controlfile 
tag '2_rmanbak_cjcdb' ;
release channel ch1;
release channel ch2;
}
EOF
exit 
###2_rmanbak.sh end###

归档备份：每小时备份一次

###arch_rmanbak.sh begin### 
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
export ORACLE_SID=cjcdb01 
rman target / log=/rman/db/arch_rmanbak.log <<EOF 
run{
allocate channel ch1 type disk maxpiecesize 1000M;
allocate channel ch2 type disk maxpiecesize 1000M;
sql "alter system archive log current";
backup
filesperset = 32
format '/rman/db/arch_%d_%T_%U.bak'
skip inaccessible
archivelog all delete input
tag 'arch_cjcdb';
backup format='ctl_%d_%T_%U.ctl' current controlfile ; 
release channel ch1;
release channel ch2;
}
EOF
exit 
###arch_rmanbak.sh end###
