使用Rman配置自动增量备份

1.在/home/NACEC/BackupDatabase/下创建backuplevel0.sh和backuplevel1.sh脚本

backuplevel0.sh内容：

#!/bin/bash

# script.:bakuplevel0.sh

# creater:liu shiming

# date:2010/6/28

# desc:backup level0 database datafile in archive with rman

# connect database

export ORACLE_BASE=/home/DBSoftware/oracle

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export ORACLE_SID=NACEC

export PATH=/home/DBSoftware/oracle/product/10.2.0/db_1/bin:$PATH

rman target / << EOF_RMAN

run{

allocate channel c1 type disk;

backup incremental level 0 tag 'db0' format '/home/liusm/BackupDatabase/rmanbackup/db0_%d_%T_%s' database include current controlfile;

sql'alter system archive log current';

backup filesperset 3 format '/home/liusm/BackupDatabase/rmanbackup/arch0_%d_%T_%s' archivelog all delete input;

release channel c1;

}

# end

backuplevel1.sh内容：

#!/bin/bash

# script.:bakuplevel1.sh

# creater:liu shiming

# date:2010/6/27

# desc:backup level1 database datafile in archive with rman

# connect database

#!/bin/bash

export ORACLE_BASE=/home/DBSoftware/oracle

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export ORACLE_SID=NACEC

export PATH=/home/DBSoftware/oracle/product/10.2.0/db_1/bin:$PATH

rman target/ << EOF_RMAN

run{

allocate channel c1 type disk;

backup incremental level 1 tag 'db1' format '/home/liusm/BackupDatabase/rmanbackup/db1_%d_%T_%s' database include current controlfile;

sql'alter system archive log current';

backup filesperset 3 format '/home/liusm/BackupDatabase/rmanbackup/arch1_%d_%T_%s' archivelog all delete input;

release channel c1;

}

# end

2.给这两个脚本授予执行的权限

[oracle@NACEC BackupDatabase]$ chmod +x  *.rcv

(注意：要试运行脚本：./backuplevel1.sh)

3.

建立基于数据库的自动备份,使用JOB完成(策略是周日、周三执行0级增量，其他时间执行1级增量)

begin

dbms_scheduler.create_job(

job_name=>'nacec_job0',

job_type=>'executable',

job_action=>'/home/NACEC/BackupDatabase/backuplevel0.sh',

repeat_interval=>'freq=weekly;byday=SUN,WED;byhour=01;byminute=00');

end;

/

exec dbms_scheduler.enable('nacec_job0');

如果想确定该job是否能执行，可以使用下面命令

exec dbms_scheduler.run_job('nacec_job0');进行验证

begin

dbms_scheduler.create_job(

job_name=>'nacec_job1',

job_type=>'executable',

job_action=>'/home/NACE
4000
C/BackupDatabase/backuplevel1.sh',

repeat_interval=>'freq=weekly;byday=MON,TUS,THE,FRI,SAT;byhour=01;byminute=00');

end;

/

exec dbms_scheduler.enable('nacec_job1');

如果想确定该job是否能执行，可以使用下面命令

exec dbms_scheduler.run_job('nacec_job1');进行验证
