这篇文章主要介绍Oracle AWR如何实现数据导入/导出,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
LINUX状态下,连接oracle用户:su - oracle
1.上传采集快照.dmp文件至服务器 (dbid:4292035712) 919219826
2.在服务器端创建目录 (即文件夹awrtest)
$> mkdir /home/oracle/awrtest
3.把第一步中上传的.dmp文件,移动到第二步中创建的文件夹中:
$> cp /var/ftp/AWR_10107.dmp(如果原文件后缀名是.DMP一定要改成小写.dmp) /home/oracle/awrtest
4.切换至sqlplus状态,并且启动数据库:
$> sqlplus / as sysdba
SQL>startup;
5. 创建数据库目录便于数据库查找
SQL> create directory AWRTEST as '/home/oracle/awrtest';
6.加载数据文件:
SQL> @?/rdbms/admin/awrload.sql
SQL>Enter value for directory_name: AWRTEST ////注意:输入directory name 时,字母需要大写
Enter value for file_name: AWR_10107 ///注意:此处不要加文件后缀名
Enter value for schema_name: AWR_STAGE //(一般默认就行)
Enter value for default_tablespace: USERS
Enter value for temporary_tablespace: //(回车默认)
出现一下文字,就说明导入成功了!
...

报错症状:(注意文件夹复权的问题!)

7.执行相关脚本:(如逻辑读脚本、db-time脚本等)
查看dbid:
SQL> select dbid from v$database; 223805804 SQL> setpagesize 500 # su - oracle
$ cd awrtest/ #根据自己的安装目录确认
$ ls (查看当前目录下文件,确认相关文件名)
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, 'hh34'),'yyyy-mm-dd hh34:mi')
else to_char(c.end_interval_time, 'yyyy-mm-dd hh34')||':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, 'hh34'),'yyyy-mm-dd hh34:mi')
else to_char(c.end_interval_time, 'yyyy-mm-dd hh34')||':30'
end
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 hh34: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.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,Oracle用户下执行如下命令:
@?/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
例如:导出时间点为:7月1日 11点 12点 负载高峰时段的AWR数据。
注意:在导出报告时,文件起名时要手动添加后缀名.html
