Linux/Unix shell 自动发送AWR report(二)

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。本文对Linux/Unix shell 自动发送AWR report的功能进行了完善和补充。

1、shell脚本

[python] view plain copy

print?

robin@SZDB:~/dba_scripts/custom/awr> more autoawr_by_time.sh

#!/bin/bash

# --------------------------------------------------------------------------+

# Generate AWR report and send mail automatically |

# Filename: autoawr_by_time.sh |

# Desc: |

# The script use to generate awr report by time period. |

# Three parameter for it. |

# para1: <ORACLE_SID> mandatory parameter |

# para2: [begin time] optional parameter |

# para3: [end time ] optional parameter |

# Deploy it by crontab as requirement |

# Usage: |

# ./autoawr_by_time.sh <instance_name> [begin time] [end time] |

# Example: |

# ./autoawr_by_time.sh TESTDB |

# --default,time period is from last midnight to today midnight |

# ./autoawr_by_time.sh TESTDB 2013031009 |

# --time period is from 2013031009 to now |

# ./autoawr_by_time.sh TESTDB 2013031009 2013031012 |

# --time period by speicifed |

# ------------------------------------------------------------

if [ -z "${1}" ] ;then

echo "Usage: "

echo " `basename $0` <ORACLE_SID> [begin_date] [end_date]"

fi

if [ -z "${3}" ] && [ -z "${2}" ];then

begin_date=`date -d yesterday +%Y%m%d`'00'

end_date=`date +%Y%m%d`'00'

elif [ -z "${3}" ]; then

begin_date=${2}

end_date=`date +%Y%m%d%H`

else

begin_date=${2}

end_date=${3}

fi

ORACLE_SID=${1}

export ORACLE_SID begin_date end_date

export MACHINE=`hostname`

echo $ORACLE_SID

echo $begin_date

echo $end_date

# --------------------------------------------------------------------

# Check the directory for store awr report,if not exist, create it

# --------------------------------------------------------------------

if [ ! -d "${AWR_DIR}" ]; then

mkdir -p ${AWR_DIR}

fi

# ----------------------------------------------

# 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_DIR/sendEmail -u $MAIL_SUB -f $MAIL_FM -t $MAIL_LIST -m $MAIL_BODY

exit 1

fi;

# ---------------------------------------------

# Generate the awr report

# ---------------------------------------------

sqlplus -S "/ as sysdba" @${AWR_CMD}/autoawr_by_time.sql $begin_date $end_date

status=$?

if [ $status != 0 ];then

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] view plain copy

print?

robin@SZDB:~/dba_scripts/custom/awr> more autoawr_by_time.sql

SET ECHO OFF;

SET VERI OFF;

SET FEEDBACK OFF;

SET TERMOUT ON;

SET HEADING OFF;

SET TRIMSPOOL ON;

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 snap_id

INTO :bid

FROM dba_hist_snapshot

WHERE TO_CHAR (end_interval_time, 'yyyymmddhh24') = '&1';

SELECT snap_id

INTO :eid

FROM dba_hist_snapshot

WHERE TO_CHAR (end_interval_time, 'yyyymmddhh24') = '&2';

SELECT dbid INTO :dbid FROM v$database;

SELECT instance_number INTO :inst_num FROM v$instance;

END;

/

--print dbid;

--print bid;

--print eid;

--print inst_num;

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 || '_' ||'&&1'||'_'||'&&2'|| '.' || '&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;

--SPOOL &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;

SET TRIMSPOOL OFF;

UNDEFINE report_name

UNDEFINE report_type

UNDEFINE fn_name

UNDEFINE lnsz

UNDEFINE no_options

exit;

3、补充说明
a、该脚本实现了基于不同时段，不同instance自动生成awr report，具体如下
b、用法为./autoawr_by_time.sh <instance_name> [begin time] [end time]，可以用于随时随地直接生成awr report
c、在省略[begin time] [end time]的情形下会自动生成昨天凌晨至今天凌晨的awr report
d、当仅仅省略[end time]时则从[begin time]开始至当前的最大snap_id来生成awr report
e、当[begin time] [end time]都被指定时则生成指定时段的awr report
f、通过调用sendEmail发送awr report，具体参考:不可或缺的 sendEmail

4、部署参考

[python] view plain copy

print?

#如果仅仅需要一整天的awr report，直接将其部署到crontab即可。

#如果需要一整天以及不同时段的awr report，则可以考虑采用如下方式来部署，将其合并到一个shell文件

robin@SZDB:~/dba_scripts/custom/awr> more awr.sh

#!/bin/bash

dt=`date +%Y%m%d`

start_date=$dt'05'

end_date=$dt'09'

/users/robin/dba_scripts/custom/awr/autoawr_by_time.sh CNMMBO #获取一整天的awr report

/users/robin/dba_scripts/custom/awr/autoawr_by_time.sh CNMMBO $start_date #获取指定起始时间至今的awr report

/users/robin/dba_scripts/custom/awr/autoawr_by_time.sh CNMMBO $start_date $end_date #获取指定时间段的awr report

exit

robin@SZDB:~/dba_scripts/custom/awr> crontab -l

# DO NOT EDIT THIS FILE - edit the master and reinstall.
