1. Oracle scheduled task:

Crontab-e

* ***/Home/oracle/workspace/scripts/bk_main.sh>/home/oracle/workspace/log/bk_err.log 2> & 1

2. Main Control Program

/Home/oracle/workspace/scripts/bk_main.sh

#! /Bin/bash

Dat = 'date + '% m''

If ($ dat = 0 ))

Then

/Home/oracle/workspace/scripts/bk _. sh 0

Elif ($ dat % 50 = 0 ))

Then

/Home/oracle/workspace/scripts/bk _. sh 2

Elif ($ dat % 40 = 0 ))

Then

/Home/oracle/workspace/scripts/bk _. sh 2

Elif ($ dat % 30 = 0 ))

Then

/Home/oracle/workspace/scripts/bk _. sh 1

Elif ($ dat % 20 = 0 ))

Then

/Home/oracle/workspace/scripts/bk _. sh 2

Elif ($ dat % 10 = 0 ))

Then

/Home/oracle/workspace/scripts/bk _. sh 2

Fi

3. Detailed backup script

Note: 'date + '% Y % m % d % k % m' | awk' {print $1 $2} ''indicates the yyyymmddhh24mi format of the current time.

/Home/oracle/workspace/scripts/bk _. sh

#! /Bin/bash

# This is a import statement.

PATH = $ PATH: $ HOME/bin

Export PATH

Export ORACLE_SID = dex

Export ORACLE_BASE =/u01/apps/oracle

Export ORACLE_HOME = $ ORACLE_BASE/product/11gr2/db_1

Export PATH = $ ORACLE_HOME/bin: $ PATH

# Use awk to cut the space char

Timst = 'date + '% Y % m % d % k % m' | awk' {print $1 $2 }''

# Use for debug

# Echo $ timst

# Create a directory like 201112140112

Mkdir/u01/backup/DEX/backups/$ timst

# Rman backup scripts

Rman target sys/xiaojun @ dex log =/home/oracle/workspace/log/rmanlog/rman _ $ timst <

Run {

Allocate channel dev1 type disk;

Allocate channel dev2 type disk;

Backup incremental level 1 database format'/u01/backup/DEX/backups/$ timst/bk _ % t _ % s' plus archivelog format'/u01/backup/DEX/backups/ $ timst/arc _ % t _ % s' delete all input;

Crosscheck backup;

Delete noprompt obsolete;

Delete noprompt expired backup;

}
