LINUX狀態(tài)下，連接oracle用戶：su - oracle
1.上傳采集快照.dmp文件至服務(wù)器 (dbid:4292035712) 919219826
2.在服務(wù)器端創(chuàng)建目錄 (即文件夾awrtest)
$> mkdir /home/oracle/awrtest
3.把第一步中上傳的.dmp文件，移動(dòng)到第二步中創(chuàng)建的文件夾中：
$> cp /var/ftp/AWR_10107.dmp(如果原文件后綴名是.DMP一定要改成小寫(xiě).dmp) /home/oracle/awrtest
4.切換至sqlplus狀態(tài),并且啟動(dòng)數(shù)據(jù)庫(kù)：
$> sqlplus / as sysdba SQL>startup;
5. 創(chuàng)建數(shù)據(jù)庫(kù)目錄便于數(shù)據(jù)庫(kù)查找
SQL> create directory AWRTEST as '/home/oracle/awrtest'；
6.加載數(shù)據(jù)文件：
SQL> @?/rdbms/admin/awrload.sql SQL>Enter value for directory_name: AWRTEST ////注意：輸入directory name 時(shí)，字母需要大寫(xiě) Enter value for file_name: AWR_10107 ///注意：此處不要加文件后綴名 Enter value for schema_name: AWR_STAGE //(一般默認(rèn)就行) Enter value for default_tablespace: USERS Enter value for temporary_tablespace: //（回車(chē)默認(rèn)）
出現(xiàn)一下文字，就說(shuō)明導(dǎo)入成功了！

7.執(zhí)行相關(guān)腳本：（如邏輯讀腳本、db-time腳本等）
查看dbid:
SQL> select dbid from v$database; 223805804 SQL> setpagesize 500 # su - oracle $ cd awrtest/ #根據(jù)自己的安裝目錄確認(rèn) $ ls (查看當(dāng)前目錄下文件，確認(rèn)相關(guān)文件名)
生成邏輯讀-語(yǔ)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：結(jié)尾的分號(hào)不能少。
生成db-time數(shù)據(jù)語(yǔ)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 ///(單實(shí)例輸入1，RAC 的根據(jù)實(shí)際情況輸入相應(yīng)的值)
Enter value for db_id: 4292035712
Enter value for instance_id: 1
8.導(dǎo)入excel表 ，生成趨勢(shì)圖
excel里邊選擇數(shù)據(jù) -導(dǎo)入-自文本
選擇導(dǎo)入的數(shù)據(jù)-生成曲線圖-雙擊橫坐標(biāo)選擇文本格式
9. 觀察趨勢(shì)圖高峰值，導(dǎo)出AWR報(bào)告，Oracle用戶下執(zhí)行如下命令：
@?/rdbms/admin/awrrpti
導(dǎo)出的AWR報(bào)告有兩種類(lèi)型格式： .txt 和 .html
系統(tǒng)默認(rèn)導(dǎo)出是.html 一般輸入時(shí)間間隔天數(shù)：7
按照步驟，連續(xù)操作就行。
Enter value for dbid: 4292035712 Using 4292035712 for database Id Enter value for inst_num: 1(輸入實(shí)例個(gè)數(shù)) Using 1 for instance number
例如：導(dǎo)出時(shí)間點(diǎn)為：7月1日 11點(diǎn) 12點(diǎn) 負(fù)載高峰時(shí)段的AWR數(shù)據(jù)。
注意：在導(dǎo)出報(bào)告時(shí)，文件起名時(shí)要手動(dòng)添加后綴名.html
