Linux/Unixshell自动发送AWRreport

观察Oracle数据库性能，Oracle自带的awr 功能为我们提供了一个近乎完美的解决方案，，通过awr特性我们可以随时从数据库提取awr报告。不过awrrpt.sql脚本执行时需要我们提供一些交互信息，因此可以将其整合到shell脚本中来实现自动产生指定时段的awr报告并发送给相关人员。本文即是描述linux shell脚本来实现此功能。

1、shell脚本

robin@SZDB:~/dba_scripts/custom/awr> more autoawr.sh
#!/bin/bash
# --------------------------------------------------------------------------+
# CHECK ALERT LOG FILE |
# Filename: autoawr.sh |
# Desc: |
# The script use to generate AWR report and send mail automatic. |
# The sql script autoawr.sql call by this shell script. |
# Default, the whole day AWR report will be gathered. |
# Deploy it to crontab at 23:30 |
# If you want to change the snap interval,please change autoawr.sql |
# and crontab configuration |
# Usage: |
# ./autoawr.sh $ORACLE_SID |
# |
# Author : Robinson |
# Blog : |
# --------------------------------------------------------------------------+
#
# --------------------------
# Check SID
# --------------------------

if [ -z "${1}" ];then
echo "Usage: "
echo " `basename $0` ORACLE_SID"
exit 1
fi

# -------------------------------
# Set environment here
# ------------------------------

if [ -f ~/.bash_profile ]; then
. ~/.bash_profile
fi

export ORACLE_SID=$1
export MACHINE=`hostname`

export AWR_CMD=/users/robin/dba_scripts/custom/awr
export AWR_DIR=/users/robin/dba_scripts/custom/awr/report
export MAIL_FM='oracle@szdb.com'
RETENTION=31

# ----------------------------------------------
# check if the database is running, if not exit
# ----------------------------------------------

db_stat=`ps -ef | grep pmon_$ORACLE_SID | grep -v grep| cut -f3 -d_`
if [ -z "$db_stat" ]; then
#date >/tmp/db_${ORACLE_SID}_stauts.log
echo " $ORACLE_SID is not available on ${MACHINE} !!!" # >>/tmp/db_${ORACLE_SID}_stauts.log
MAIL_SUB=" $ORACLE_SID is not available on ${MACHINE} !!!"
MAIL_BODY=" $ORACLE_SID is not available on ${MACHINE} at `date` when try to generate AWR."
$MAIL_DIR/sendEmail -u $MAIL_SUB -f $MAIL_FM -t $MAIL_LIST -m $MAIL_BODY
exit 1
fi;
