1、Rman备份脚本 

备份策略：周天0级备份，其他时候1级备份

2、删除归档备份和oracle trc等文件的脚本

#!/bin/ksh
# ##################################################################
#
#   delete_archvivelog_backup_and_trc_trm_file.sh
#
#
# ##################################################################
PATH=/usr/bin:/usr/ucb:/etc:.:/usr/X/bin:/bin
export PATH
#find /opt/kfsjora_backup -mtime +15 -name "arch_*" -exec rm "{} /;"
find /opt/kfsjora_backup -mtime +15 -name "arch_*" -exec rm {} \;
find /opt/oracle/admin/kfsjora/adump/ -mtime +15 -name "*.aud" -exec rm {} \;
find /opt/oracle/diag/rdbms/kfsjora/kfsjora/cdump/ -mtime +15 -name "*" -exec rm -fr {} \;
find /opt/oracle/diag/rdbms/kfsjora/kfsjora/trace/ -mtime +15 -name "*.tr?" -exec rm {} \;

 

3、导出Rman catalog数据 的脚本

#!/bin/ksh
# ##################################################################
#
#   exprman.sh
#
#
# ##################################################################
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME
PATH=/usr/bin:/usr/ucb:/etc:.:/usr/X/bin:/bin:$ORACLE_HOME/bin:/usr/sbin
export PATH
EXP_BASE=/home/oracle/backup/exprman
export EXP_BASE
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export NLS_LANG

if [ -s  "$EXP_BASE/kfcrman_new.dmp" ];then
  rm $EXP_BASE/kfcrman_old.dmp
  mv $EXP_BASE/kfcrman_new.dmp $EXP_BASE/kfcrman_old.dmp
fi
exp kfcrman/kfcrman@kfcrman tablespaces=KFC3850 file=$EXP_BASE/kfcrman_new.dmp >>$EXP_BASE/../log/expkfcrman.log 2>&1

4、设置 crontab 定期执行上述脚本

$crontab -e

加入如下内容

00 1 * * * /home/oracle/backup/script/kfc_incremental_hot_database_backup.sh &
00 2 * * * /home/oracle/backup/script/delete_archvivelog_backup_and_trc_trm_file.sh >/home/oracle/backup/log/log_delete_archvivelog_backup_and_trc_trm_file.log 2>&1 &
00 5 1 * * /home/oracle/backup/script/expkfcrman.sh
