9     在/home/NACEC/BackupDatabase/下创建backuplevel0.rcv和backuplevel1.rcv脚本
backuplevel0.rcv内容：
#   script.:bakuplevel0.rcv
#   creater:liu shiming
#   date:2010/6/28
#   desc:backup level0 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 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.rcv内容：
#   script.:bakuplevel1.rcv
#   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
    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.rcv)
11   用crontab指定执行时间
[oracle@NACEC BackupDatabase]$ crontab -e
crontab: installing new crontab
[oracle@NACEC BackupDatabase]$ crontab -l
0 1 * * 0  /home/NACEC/BackupDatabase/backuplevel0.rcv
0 1 * * 3  /home/NACEC/BackupDatabase/backuplevel0.rcv
0 1 * * 1-2  /home/NACEC/BackupDatabase/backuplevel1.rcv
0 1 * * 4-6  /home/NACEC/BackupDatabase/backuplevel1.rcv
周日和周三凌晨1：00执行0级备份，周一、二、四、五、六凌晨1：00执行1级备份
内容：
0 1 * * 0  /home/NACEC/BackupDatabase/backuplevel0.rcv
0 1 * * 3  /home/NACEC/BackupDatabase/backuplevel0.rcv
0 1 * * 1-2  /home/NACEC/BackupDatabase/backuplevel1.rcv
0 1 * * 4-6  /home/NACEC/BackupDatabase/backuplevel1.rcv

或者建立基于数据库的自动备份,使用JOB完成
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');

begin
dbms_scheduler.create_job(
job_name=>'nacec_job1',
job_type=>'executable',
job_action=>'/home/NACEC/BackupDatabase/backuplevel1.sh',
repeat_interval=>'freq=weekly;byday=MON,TUS,THE,FRI,SAT;byhour=01;byminute=00');
end;
