本文旨在用來指導項目人員自行提取Oracle數據庫的AWR報告.
1.當前連接實例的AWR報告提取：@?/rdbms/admin/awrrpt
2.RAC的其他實例AWR報告提取：@?/rdbms/admin/awrrpti
1.當前連接實例的AWR報告提取：@?/rdbms/admin/awrrpt
SQL> @?/rdbms/admin/awrrpt //注意輸入的@?/rdbms/admin/awrrpt 中間沒有任何空格，需要在數據庫服務器上Oracle用戶登陸，sqlplus / as sysdba 進入SQL> 下執行.
Current Instance ~~~~~~~~~~~~~~~~ DB Id DB Name Inst Num Instance ----------- ------------ -------- ------------ 857123342 JY 1 jy1 Specify the Report Type ~~~~~~~~~~~~~~~~~~~~~~~ Would you like an HTML report, or a plain text report? Enter 'html' for an HTML report, or 'text' for plain text Defaults to 'html' Enter value for report_type: //注意這里直接回車即可，默認就是html格式的 Type Specified: html Instances in this Workload Repository schema ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ DB Id Inst Num DB Name Instance Host ------------ -------- ------------ ------------ ------------ 857123342 2 JY jy2 rac2-server * 857123342 1 JY jy1 rac1-server Using 857123342 for database Id Using 1 for instance number Specify the number of days of snapshots to choose from ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Entering the number of days (n) will result in the most recent (n) days of snapshots being listed. Pressing <return> without specifying a number lists all completed snapshots. Enter value for num_days: 1 //注意這里根據實際需要選擇幾天的AWR報告，一般取最近的AWR報告選擇1天即可
Listing the last day's Completed Snapshots Snap Instance DB Name Snap Id Snap Started Level ------------ ------------ --------- ------------------ ----- jy1 JY 92 16 Oct 2014 07:32 1 93 16 Oct 2014 09:00 1 94 16 Oct 2014 10:00 1 95 16 Oct 2014 11:00 1 Specify the Begin and End Snapshot Ids ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Enter value for begin_snap: 94 Begin Snapshot Id specified: 94 Enter value for end_snap: 95 End Snapshot Id specified: 95 //注意這里輸入的begin_snap 和 end_snap都是根據上面具體時間點對應的實際Snap Id那一列決定的. 比如我要選 09:00 - 10:00的話，那起始就應該是93和94. Specify the Report Name ~~~~~~~~~~~~~~~~~~~~~~~ The default report file name is awrrpt_1_94_95.html. To use this name, press <return> to continue, otherwise enter an alternative. Enter value for report_name: //這里默認回車即可，名字會有一個默認值的。
Using the report name awrrpt_1_94_95.html
此處省略大量屏幕輸出..

注：生成的報告文件發送給我即可,例如此處就是指awrrpt_1_94_95.html文件，代表的是2014年10月16日10點~11點這一小時的數據庫實例jy1的工作負載報告。
2.RAC的其他實例AWR報告提取：@?/rdbms/admin/awrrpti

Pressing <return> without specifying a number lists all completed snapshots. Enter value for num_days: Listing all Completed Snapshots Snap Instance DB Name Snap Id Snap Started Level ------------ ------------ --------- ------------------ ----- jy2 JY 91 14 Oct 2014 10:10 1 92 16 Oct 2014 07:32 1 93 16 Oct 2014 09:00 1 94 16 Oct 2014 10:00 1 95 16 Oct 2014 11:00 1 Specify the Begin and End Snapshot Ids ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Enter value for begin_snap: 94 Begin Snapshot Id specified: 94 Enter value for end_snap: 95 End Snapshot Id specified: 95 Specify the Report Name ~~~~~~~~~~~~~~~~~~~~~~~ The default report file name is awrrpt_2_94_95.html.

3.手工生成一個快照：
exec dbms_workload_repository.create_snapshot();
SQL> exec dbms_workload_repository.create_snapshot(); PL/SQL procedure successfully completed.
