Linux/Unix shell自动发送AWR report
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
[python]
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 $ORACLE_SID |
# |
# Author : Robinson |
# |
# --------------------------------------------------------------------------+
#
# --------------------------
# Check SID
# --------------------------
if [ -z "${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=$1
export MACHINE=`hostname`
export MAIL_DIR=/users/robin/dba_scripts/sendEmail-v1.56
export MAIL_LIST='Robinson.cheng@12306.com'
export AWR_CMD=/users/robin/dba_scripts/custom/awr
export AWR_DIR=/users/robin/dba_scripts/custom/awr/report
export MAIL_FM='oracle@szdb.com'
RETENTION=31
# ----------------------------------------------
# check if the database is running, if not exit
# ----------------------------------------------
db_stat=`ps -ef | grep pmon_$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;
# ----------------------------------------------
# Generate awr report
# ----------------------------------------------
$ORACLE_HOME/bin/sqlplus /nolog<
connect / as sysdba;
@${AWR_CMD}/autoawr.sql;
exit;
EOF
status=$?
if [ $status != 0 ];then
echo " $ORACLE_SID is not available on ${MACHINE} !!!" # >>/tmp/db_${ORACLE_SID}_stauts.log
MAIL_SUB=" Occurred error while generate AWR for ${ORACLE_SID} !!!"
MAIL_BODY=" Some exceptions encountered during generate AWR report for $ORACLE_SID on `hostname`."
$MAIL_DIR/sendEmail -u $MAIL_SUB -f $MAIL_FM -t $MAIL_LIST -m $MAIL_BODY
exit
fi
# ------------------------------------------------
# Send email with AWR report
# ------------------------------------------------
dt=`date -d yesterday +%Y%m%d`
filename=`ls ${AWR_DIR}/${ORACLE_SID}_awrrpt_?_${dt}*`
if [ -e "${filename}" ];then
MAIL_SUB="AWR report from ${ORACLE_SID} on `hostname`."
MAIL_BODY="This is an AWR report from ${ORACLE_SID} on `hostname`."
$MAIL_DIR/sendEmail -u $MAIL_SUB -f $MAIL_FM -t $MAIL_LIST -m $MAIL_BODY -a ${filename}
echo ${filename}
fi
# ------------------------------------------------
# Removing files older than $RETENTION parameter
# ------------------------------------------------
find ${AWR_DIR} -name "*awrrpt*" -mtime +$RETENTION -exec rm {} /;
exit
2、产生awr report 的sql脚本
[sql]
robin@SZDB:~/dba_scripts/custom/awr> more autoawr.sql
SET ECHO OFF;
SET VERI OFF;
SET FEEDBACK OFF;
SET TERMOUT ON;
SET HEADING OFF;
VARIABLE rpt_options NUMBER;
DEFINE no_options = 0;
define ENABLE_ADDM = 8;
REM according to your needs, the value can be 'text' or 'html'
DEFINE report_type='html';
BEGIN
:rpt_options := &no_options;
END;
/
VARIABLE dbid NUMBER;
VARIABLE inst_num NUMBER;
VARIABLE bid NUMBER;
VARIABLE eid NUMBER;
BEGIN
SELECT MIN (snap_id) INTO :bid
FROM dba_hist_snapshot
WHERE TO_CHAR (end_interval_time, 'yyyymmdd') = TO_CHAR (SYSDATE, 'yyyymmdd');
SELECT MAX (snap_id) INTO :eid FROM dba_hist_snapshot;
SELECT dbid INTO :dbid FROM v$database;
SELECT instance_number INTO :inst_num FROM v$instance;
END;
/
COLUMN ext NEW_VALUE ext NOPRINT
COLUMN fn_name NEW_VALUE fn_name NOPRINT;
COLUMN lnsz NEW_VALUE lnsz NOPRINT;
SELECT 'txt' ext
FROM DUAL
WHERE LOWER ('&report_type') = 'text';
SELECT 'html' ext
FROM DUAL
WHERE LOWER ('&report_type') = 'html';
SELECT 'awr_report_text' fn_name
FROM DUAL
WHERE LOWER ('&report_type') = 'text';
SELECT 'awr_report_html' fn_name
FROM DUAL
WHERE LOWER ('&report_type') = 'html';
SELECT '80' lnsz
FROM DUAL
WHERE LOWER ('&report_type') = 'text';
SELECT '1500' lnsz
FROM DUAL
WHERE LOWER ('&report_type') = 'html';
set linesize &lnsz;
COLUMN report_name NEW_VALUE report_name NOPRINT;
SELECT instance_name || '_awrrpt_' || instance_number || '_' || b.timestamp || '.' || '&ext'
report_name
FROM v$instance a,
(SELECT TO_CHAR (begin_interval_time, 'yyyymmdd') timestamp
FROM dba_hist_snapshot
WHERE snap_id = :bid) b;
SET TERMOUT OFF;
SPOOL $AWR_DIR/&report_name;
SELECT output
FROM TABLE (DBMS_WORKLOAD_REPOSITORY.&fn_name (:dbid,
:inst_num,
:bid,
:eid,
:rpt_options));
SPOOL OFF;
SET TERMOUT ON;
CLEAR COLUMNS SQL;
TTITLE OFF;
BTITLE OFF;
REPFOOTER OFF;
UNDEFINE report_name
UNDEFINE report_type
UNDEFINE fn_name
UNDEFINE lnsz
UNDEFINE no_options
3、补充说明
a、shell脚本中首先判断指定的实例是否处于available，如果不可用则退出
b、接下来调用autoawr.sql脚本来产生awr report
c、产生awr report后，如果文件存在则自动发送邮件
d、autoawr.sql脚本中是产生awr report的主要部分，主要是调用了DBMS_WORKLOAD_REPOSITORY.&fn_name过程
e、该脚本是生成一整天awr report，即从当天的零点至第二天零点
f、sql脚本的几个参数需要确定的是dbid，实例号，以及snap的开始与结束id，rpt_options用于确定报告是否带addm项
g、可以根据需要定制所需的snap的起止id，需修改SQL来获取正确的snap id，来生成所需的报告
h、根据需要修改fn_name定制生成awr报告为txt或html类型，report_name则是确定最终文件名
i、AWR 报告的两个snap 之间不能有重启DB的操作,否则有可能错误(未测试过)
j、该脚本支持Oracle 10g/11g，有关详细的产生awr report脚本说明请参考oracle自带的awrrpt.sql,awrrpti.sql
