Oracle AWR 数据导入/导出的步骤

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）

出现以下文字，就说明导入成功了！

... Creating AWR_STAGE user
 
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|  Loading the AWR data from the following
|  directory/file:

|  *** AWR Load Started ...

|  This operation will take a few moments. The
|  progress of the AWR load operation can be
|  monitored in the following directory/file:

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, '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'
      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 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.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
