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));SQL>select output from table(dbms_workload_repository.awr_report_text(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.sqlconn / as sysdba;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;-- 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;beginselect 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 noprintcolumn 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_nameundefine report_typeundefine fn_nameundefine lnszundefine NO_OPTIONSexit[oracle@rac1 admin]$这个脚本是收集过去48个小时的snap 来生成AWR。 生成的文件名称是awr .html，这个也是spool 指定的，可以生成其他名称。三. 自动上传AWR的Python脚本在这个脚本里做2件事，第一是调用第二步里的SQL脚本，生成awr报告，然后将AWR 发送到指定邮箱。createSendAWR.py#!/usr/bin/python#coding=gbk#created by tianlesoftware#2011-4-12import osimport sysimport smtplibimport pickleimport mimetypesfrom email.MIMEText import MIMETextfrom email.MIMEImage import MIMEImagefrom email.MIMEMultipart import MIMEMultipartSMTP_SERVER='192.168.1.120'EMAIL_USER='user'EMAIL_PASSWD='pwd'EMAIL_SUBJECT='192.168.88.209 AWR Report'FROM_USER='daimingming@1876.cn'TO_USERS=['daimingming@1876.cn','dvd.dba@gmail.com']def createawr():pipe = os.popen(' /u01/app/oracle/product/10.2.0/db_1/bin/sqlplus /nolog @awrrpt.sql')def mysendmail(fromaddr,toaddrs,subject):COMMASPACE=','msg = MIMEMultipart()msg['From'] = fromaddrmsg['To'] = COMMASPACE.join(toaddrs)msg['Subject'] = subjecttxt = MIMEText("192.168.88.209 AWR Report, The report be send at 9 AM every day ")msg.attach(txt)fileName = r'/home/oracle/awr.html'ctype, encoding = mimetypes.guess_type(fileName)if ctype is None or encoding is not None:ctype = 'application/octet-stream'maintype, subtype = ctype.split('/', 1)att = MIMEImage((lambda f: (f.read(), f.close()))(open(fileName, 'rb'))[0], _subtype = subtype)att.add_header('Content-Disposition', 'attachment', filename = fileName)msg.attach(att)server=smtplib.SMTP(SMTP_SERVER)server.login(EMAIL_USER,EMAIL_PASSWD)server.sendmail(fromaddr,toaddrs,msg.as_string())server.quit()if __name__=='__main__':createawr()mysendmail(FROM_USER, TO_USERS, EMAIL_SUBJECT)#print 'send successful'四. 将Python 添加到crontab[oracle@qs-wg-db1 scripts]$ crontab -l40 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。
