概述
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

skip inaccessible database
include current controlfile

release channel ch2;
}
EOF
exit
###0_rmanbak.sh end###
周二、三:2级别备份

归档备份:每小时备份一次
###arch_rmanbak.sh begin###

export ORACLE_SID=cjcdb01
rman target / log=/rman/db/arch_rmanbak.log <

tag 'arch_cjcdb';
backup format='ctl_%d_%T_%U.ctl' current controlfile ;
