Oracle rman备份计划任务设计

使用crontab计划任务，和rman备份脚本，做一个完整的rman自动备份。
1、计划任务设计：

#  crontab -e

00 03 01 * * /home/oracle/rman/dbfull.sh
00 01 * * 0 /home/oracle/rman/db0.sh
00 01 * * 1 /home/oracle/rman/db2.sh
00 01 * * 2 /home/oracle/rman/db2.sh
00 01 * * 3 /home/oracle/rman/db1.sh
00 01 * * 4 /home/oracle/rman/db2.sh
00 01 * * 5 /home/oracle/rman/db2.sh
00 01 * * 6 /home/oracle/rman/db2.sh

计划任务描述：

2、将脚本放在/home/oracle/rman 并赋予可执行权限。

[oracle@RHEL rman]$ pwd
/home/oracle/rman
[oracle@RHEL rman]$ chmod +x *
[oracle@RHEL rman]$ ll -h
total 32K
-rwxr-xr-x 1 root root 230 Mar 11 15:19 db0.sh
-rwxr-xr-x 1 root root 230 Mar 11 15:19 db1.sh
-rwxr-xr-x 1 root root 230 Mar 11 15:19 db2.sh
-rwxr-xr-x 1 root root 414 Mar 11 15:19 dbfull.rcv
-rwxr-xr-x 1 root root 235 Mar 11 15:19 dbfull.sh
-rwxr-xr-x 1 root root 417 Mar 11 15:19 dbl0.rcv
-rwxr-xr-x 1 root root 402 Mar 11 15:19 dbl1.rcv
-rwxr-xr-x 1 root root 402 Mar 11 15:19 dbl2.rcv

3、脚本内容核对，检查文件夹路径、环境变量是否准确。
