转 awr自动收集脚本

1. remote get awr report

#!/usr/bin/ksh

####sample: sh awr.sh 20170515 20170516 AWR

### default it will collect every 30 or every hours awr report .

####define remote connect database

2.般我们都是条用awrrpt.sql 来创建我们的AWR报告。 
我们先看下这个脚本的具体内容：

[oracle@rac1 admin]$ cat awrrpt.sql | grep -v 'Rem'|grep -v '^--'

set echo off heading on underline 
on;

column inst_num  heading "Inst Num"  new_value inst_num  format 99999;

column inst_name heading

column db_name   heading "DB Name"   new_value db_name   format a12;

column dbid      heading "DB Id"     new_value dbid      format 9999999999 just

undefine num_days;

undefine report_type;

undefine report_name;

undefine begin_snap;

undefine end_snap;

在以上的脚本里，我们发现它只是生成了一些变量，然后把这些变量传给了另一个脚本：awrrpti.sql。 我们看下awrrpti.sql 脚本的具体内容：

[oracle@rac1 admin]$ cat awrrpti.sql | grep -v 'Rem'|grep -v '^--'

set echo off;

set veri off;

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

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 -

--    
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));

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。

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。
