Oracle AWR数据导入/导出的步骤(二)
脚本：（如逻辑读脚本、db-time脚本等）
[查看dbid:
SQL> select dbid from v$database;
223805804
setpagesize 500
$ cd awrtest/
ls (查看当前文件名字)
生成逻辑读-语句：
SELECT case when to_number(to_char(c.end_interval_time, 'mi'))<15 or to_number(to_char(c.end_interval_time, 'mi'))>=45
then to_char(round(c.end_interval_time, 'hh24'),'yyyy-mm-dd hh24:mi')
else to_char(c.end_interval_time, 'yyyy-mm-dd hh24')||':30'
end end_time,
case when max(decode(a.instance_number, 1, a.value - b.value, null))<0 then null
else max(decode(a.instance_number, 1, a.value - b.value, null))
end INST1,
case when max(decode(a.instance_number, 2, a.value - b.value, null))<0 then null
else max(decode(a.instance_number, 2, a.value - b.value, null))
end INST2,
case when max(decode(a.instance_number, 3, a.value - b.value, null))<0 then null
else max(decode(a.instance_number, 3, a.value - b.value, null))
end INST3,
case when max(decode(a.instance_number, 4, a.value - b.value, null))<0 then null
else max(decode(a.instance_number, 4, a.value - b.value, null))
end INST4
FROM sys.wrh$_sysstat a, sys.wrh$_sysstat b, sys.wrm$_snapshot c
WHERE a.stat_id =3143187968
AND b.stat_id = a.stat_id
AND a.snap_id = b.snap_id + 1
AND a.snap_id = c.snap_id
and a.dbid =&dbid
and b.dbid = a.dbid
and c.dbid = a.dbid
and a.instance_number = b.instance_number
and a.instance_number = c.instance_number
group by a.snap_id, case when to_number(to_char(c.end_interval_time, 'mi'))<15 or to_number(to_char(c.end_interval_time, 'mi'))>=45
then to_char(round(c.end_interval_time, 'hh24'),'yyyy-mm-dd hh24:mi')
else to_char(c.end_interval_time, 'yyyy-mm-dd hh24')||':30'
ORDER BY a.snap_id;
注意：结尾的分号不能少。
生成db-time数据语句：
SELECT TO_CHAR(b.end_interval_time, 'yyyy-mm-dd hh24:mi:ss') snap_time,
--'DB Time(s)',
CASE
WHEN (ROUND((a.VALUE - lag(a.VALUE, 1) OVER(ORDER BY a.snap_id)) / 1000000))<0
THEN 0
ELSE ROUND((a.VALUE - lag(a.VALUE, 1) OVER(ORDER BY a.snap_id)) / 1000000)
END AS "db time(s)"
FROM
(SELECT snap_id,
VALUE
FROM dba_hist_sys_time_model
WHERE stat_name = 'DB time'
and dbid=&db_id
AND INSTANCE_NUMBER = &instance_id) a,
dba_hist_snapshot b
WHERE b.dbid=&db_id
AND a.snap_id = b.snap_id
AND b.INSTANCE_NUMBER = &instance_id
--AND b.end_interval_time > sysdate-30
ORDER BY 1;
Enter value for db_id: 4292035712
Enter value for instance_id: 1 (单实例输入1，RAC 的根据实际情况输入相应的值)
Enter value for db_id: 4292035712
Enter value for instance_id: 1
8.复制出数据到TXT，导入excel表 ，生成趋势图
excel里边选择数据 -导入-自文本
选择导入的数据-生成曲线图-双击横坐标选择文本格式-
9. 观察趋势图高峰值，导出AWR报告
7月1日 11点 12点 高峰
@ /rdbms/admin/awrrpti
导出的AWR报告有两种类型格式： .txt 和 .html
系统默认导出是.html 一般输入时间间隔天数：7
按照步骤，连续操作就行
Enter value for dbid: 4292035712
Using 4292035712 for database Id
Enter value for inst_num: 1(输入实例个数)
Using 1 for instance number
注意：在导出报告时，文件起名时要加后缀名.html
