(Oracle)自定义调用AWR

Oracle->自动发送AWR报告

需求描述：

每日或定期手动使用AWR报告来检查Oracle数据库状态不仅耗时也费力，需求使用脚本自动收集AWR报告。

分析方案：

　　收集AWR报告的脚本：$ORACLE_HOME/rdbms/admin/awrrpt.sql ->主要运行脚本。

　　首先来查看脚本都做了写什么，用了哪些视图。

cat $ORACLE_HOME/rdbms/admin/awrrpt.sql |grep -v 'Rem'|grep -v '^--' (排除‘Rem’和‘--’相关

得到主要信息->

select d.dbid dbid

, d.name db_name

, i.instance_number inst_num

, i.instance_name inst_name

from v$database d,

v$instance i;

和关联脚本@@awrrpti

再查看@@awrrpti脚本都执行了些什么

cat $ORACLE_HOME/rdbms/admin/awrrpt.sql |grep -v 'Rem'|grep -v '^--' (排除‘Rem’和‘--’相关注释)

得到核心内容->（这就是生成AWR报告的程序）

spool &report_name;
 
select output from table(dbms_workload_repository.&fn_name( :dbid,
                                                            :inst_num,
                                                            :bid, :eid,
                                                            :rpt_options ));
 
spool off;
 
select output from table(dbms_workload_repository.&fn_name( :dbid,:inst_num,:bid, :eid,:rpt_options ));
 
&fn_name->类型名称如awr_report_html和awr_report_text
:dbid->数据库id号
:inst_num->实例名
:bid->snap开始id
:eid->snap结束id
:rpt_options->控制显示ADDM

关联脚本

@@awrinput.sql ->主要获取snapshots id号

@@awrinpnm.sql 'awrrpt_' &&ext ->主要生成AWR报告名称

AWR生成脚本的流程：

@awrrpt.sql（提供dbid和inst_num）

@@awrrpti.sql(主程式脚本)

@@awrinput.sql(提供snap id)

@@awrinpnm.sql(提供awr生成名称)

select output from table(dbms_workload_repository.&fn_name( :dbid,:inst_num,:bid, :eid,:rpt_options ));(生成awr报表)

制定脚本：<ora_auto_awrrpt.sql>

复制 @@awrrpti.sql内容并且加以更正就行

--conn / 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;
variable dbname varchar2(9);
variable btime number;
variable etime number;
begin
select dbid into :dbid  from v$database;
select instance_number into :inst_num from v$instance;
select max(snap_id)-24 into :bid from dba_hist_snapshot where DBID=:dbid;--生成的awr 快照开始时间可以自定义。注意如果中间有重启数据库，会导致获取awr报告失败。
select max(snap_id) into :eid from dba_hist_snapshot where DBID=:dbid;
select lower(NAME) into :dbname  from v$database;
select to_char(end_interval_time,'YYYYMMDDHH24') into :btime from dba_hist_snapshot  where snap_id=:bid;
select to_char(end_interval_time,'DDHH24')  into :etime from dba_hist_snapshot  where snap_id=:eid;

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';

select :dbname||'_'||:btime||'to'||:etime||'.'||'&ext' report_name from dual;
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 :dbname||'_'||:btime||'to'||:etime||'.'||'&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

设定shell脚本定时执行并发送邮件。
