4、创建RMAN备份shell脚本
[python]
oracle@BKDB01p:/u02/database/common/rman_scripts> more db_bak_rman_catalog.sh
##===========================================================
## File name: db_bak_rman_catalog.sh
## Usage: db_bak_rman_catalog.sh
## Desc:
## The script uses to backup database with level 0.
##============================================================
#!/bin/bash
# User specific environment and startup programs
if [ -f ~/.bash_profile ];
then
. ~/.bash_profile
fi
# --------------------------
# Check SID
# --------------------------
if [ -z "${1}" ];then
echo "Usage: "
echo " `basename $0` ORACLE_SID"
exit 1
fi
# -------------------------------
# Set environment here
# -------------------------------
ORACLE_SID=${1}; export ORACLE_SID
TIMESTAMP=`date +%Y%m%d%H%M`; export TIMESTAMP
LOG_DIR=/u02/database/${ORACLE_SID}/backup export LOG_DIR
RMAN_LOG=${LOG_DIR}/${ORACLE_SID}_bak_${TIMESTAMP}.log
SSH_LOG=${LOG_DIR}/${ORACLE_SID}_bak_full_${TIMESTAMP}.log
MAIL_DIR=/users/oracle/sendEmail-v1.56
MAIL_FM=oracle@BKDB01p
RETENTION=5
echo "----------------------------------------------------------------" 》${SSH_LOG}
echo "Step 1. Start rman to backup at `date`." 》${SSH_LOG}
echo "----------------------------------------------------------------" 》${SSH_LOG}
$ORACLE_HOME/bin/rman log=${RMAN_LOG} 《EOF

$MAIL_DIR/sendEmail -f $MAIL_FM -u "Failed RMAN backup for $ORACLE_SID on `hostname`." -t [e-mail] -o message-file=${SSH_LOG}
exit
else
echo "" 》${SSH_LOG}
echo "=====>MSG2: No error found during RMAN backup peroid at `date`" 》${SSH_LOG}
rm -rf ${RMAN_LOG} 2>/dev/null

exit
5、自动FTP archivelog脚本
[python]
oracle@BKDB01p:/u02/database/common/rman_scripts> more autoftp_arch.sh
#!/bin/bash
ORACLE_SID=${1}; export ORACLE_SID
TIMESTAMP=`date +%Y%m%d%H%M`; export TIMESTAMP
LOG_DIR=/u02/database/${ORACLE_SID}/backup
#Define FTP variable
SRC_DB_BAK_DIR=/u02/database/${ORACLE_SID}/archive
SRC_ADD=10.1.2.101
TARG_DB_BAK_DIR=/u02/database/${ORACLE_SID}
RSYN_LOG=${LOG_DIR}/rsync_arc_${TIMESTAMP}.log
RSYN_ERR_LOG=${LOG_DIR}/rsync_arc_${TIMESTAMP}_err.log
rsync -avzSH --progress --delete-after oracle@${SRC_ADD}:${SRC_DB_BAK_DIR} ${TARG_DB_BAK_DIR} >${RSYN_LOG} 2>${RSYN_ERR_LOG}
RV=$?
if [ ! -s ${RSYN_ERR_LOG} ];then
rm -rf ${RSYN_ERR_LOG} 2>/dev/null
else
mail -s "Failed FTP archive log for $ORACLE_SID on `hostname`" [e-mail] fi
exit
6、部署备份脚本到crontab
如果你的数据库比较少，则直接将上面的备份脚本与自动FTP archivelog脚本部署到crontab.
如果你的数据库比较多，建议将上面的脚本封装到另外的一个文件，然后部署到crontab.
如下面的full_bak_by_rman.sh实际上是包含了多个db_bak_rman_catalog.sh ,后面的多个full开头的使用类是的原理。
#Rman backup and restore database
0 1 * * 1-6 /u02/database/common/rman_scripts/full_bak_by_rman.sh
0 3 * * 1-6 /u02/database/common/rman_scripts/full_resotre_by_rman.sh #这个是用来还原的脚本
#Auto ftp archive log from prod to bak server
*/16 7-20 * * 1-6 /u02/database/common/rman_scripts/full_autoftp_arch.sh
