       这个脚本才是我们真正生成AWR的脚本。 在这个脚本里面，提示我们选择AWR报告的类型。

通过上面的2个脚本，我们将AWR报告简化一下：

       select output from

table(dbms_workload_repository.&fn_name(:dbid, :inst_num,:bid, :eid,:rpt_options ));

这条语句就是整个AWR报告的核心：

（1）&fn_name ：决定AWR报告的类型，有2个值：awr_report_html和awr_report_text。

（2）dbid，inst_num,bid,eid 可以通过dba_hist_snapshot查询. bid 指的是begin snap_id, eid 指的是end snap_id.

SQL> select * from (select snap_id,dbid,instance_number from dba_hist_snapshot  order by snap_id) where rownum<10;

   SNAP_ID       DBID INSTANCE_NUMBER

---------- ---------- ---------------

       184  809910293               2

       184  809910293               1

       185  809910293               2

       185  809910293               1

       186  809910293               2

       186  809910293               1

       187  809910293               2

       187  809910293               1

       188  809910293               2

9 rows selected.

       我这里是个RAC 环境， 通过这个可以看出在每个节点上都保存着AWR的信息。

（3）rpt_options：该参数控制是否显示ADDM的。

--    No options. Setting this will not show the ADDM

--    specific portions of the report.

--    This is the default setting.

--

--  ENABLE_ADDM -

--    Show the ADDM specific portions of the report.

--    These sections include the Buffer Pool Advice,

--    Shared Pool Advice, PGA Target Advice, and

--    Wait Class sections.

define NO_OPTIONS   = 0;

define ENABLE_ADDM  = 8;

有了上面的数据之后，我们就可以使用如下SQL直接生成AWR报告了。

SQL>select output from table(dbms_workload_repository.awr_report_html(809910293, 2,220,230,0));

二. 生成AWR报告 SQL脚本

       以上写了这么多，就是为了一个脚本：myawrrpt.sql.  这个脚本就是自动的去收集信息。 因为如果我们是调用awrrpt.sql的话，需要输入一些参数。 我们修改一下脚本，让它根据我们的需求来收集信息，这样就不用输入参数了。

[oracle@rac1 admin]$ cat myawrrpt.sql

conn / as sysdba;

set veri off;

set feedback off;

set termout on;

set heading off;

variable rpt_options number;

define NO_OPTIONS = 0;

define ENABLE_ADDM = 8;

-- 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 max(snap_id)-48 into :bid from dba_hist_snapshot;

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;

-- print the AWR results into the report_name file using the spool command:

column report_name new_value report_name noprint;

select 'awr'||'.'||'&ext' report_name from dual;

set termout off;

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;

undefine report_name

undefine report_type

undefine fn_name

undefine lnsz

undefine NO_OPTIONS

exit

[oracle@rac1 admin]$

       这个脚本是收集过去48个小时的snap 来生成AWR。 生成的文件名称是awr .html，这个也是spool 指定的，可以生成其他名称。

三. 自动上传AWR的Python脚本

       在这个脚本里做2件事，第一是调用第二步里的SQL脚本，生成awr报告，然后将AWR 发送到指定邮箱。

createSendAWR.py

#!/usr/bin/python

#coding=gbk

#created by tianlesoftware

#2011-4-12

import os

import sys

import smtplib

import pickle

import mimetypes

from email.MIMEText import MIMEText

from email.MIMEImage import MIMEImage

from email.MIMEMultipart import MIMEMultipart

SMTP_SERVER='192.168.1.120'

EMAIL_USER='user'

EMAIL_PASSWD='pwd'

EMAIL_SUBJECT='192.168.88.209 AWR Report'

FROM_USER='daimingming@1876.cn'

TO_USERS=['daimingming@1876.cn','dvd.dba@gmail.com']

  pipe = os.popen(' /u01/app/oracle/product/10.2.0/db_1/bin/sqlplus /nolog @awrrpt.sql')

def mysendmail(fromaddr,toaddrs,subject):

        COMMASPACE=','

        msg = MIMEMultipart()

        msg['From'] = fromaddr

        msg['To'] = COMMASPACE.join(toaddrs)

        msg['Subject'] = subject

        txt = MIMEText("192.168.88.209 AWR Report, The report be send at 9 AM every day ")

        msg.attach(txt)  

        fileName = r'/home/oracle/awr.html'

        ctype, encoding = mimetypes.guess_type(fileName)

        if ctype is None or encoding is not None:

            ctype = 'application/octet-stream'

        maintype, subtype = ctype.split('/', 1)

        att = MIMEImage((lambda f: (f.read(), f.close()))(open(fileName, 'rb'))[0], _subtype = subtype)

        att.add_header('Content-Disposition', 'attachment', filename = fileName)

        msg.attach(att)  

        server=smtplib.SMTP(SMTP_SERVER)

        server.login(EMAIL_USER,EMAIL_PASSWD)

        server.sendmail(fromaddr,toaddrs,msg.as_string())

        server.quit()

if __name__=='__main__':

               createawr()

        mysendmail(FROM_USER, TO_USERS, EMAIL_SUBJECT)

        #print 'send successful'

四. 将Python 添加到crontab

[oracle@qs-wg-db1 scripts]$ crontab -l

40 17 * * * export ORACLE_HOME='/home/oracle_app' && ORACLE_SID=XX  && cd /u01/backup/scripts && /u01/backup/scripts/createSendAWR.py >/u01/backup/scripts/createSendAWR.log 2>&1

我这里因为报了

SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory

的错误，所以把变量加了上去。
