本文旨在用来指导项目人员自行提取Oracle数据库的AWR报告.
1.当前连接实例的AWR报告提取：@?/rdbms/admin/awrrpt
sql> @?/rdbms/admin/awrrpt //注意输入的@?/rdbms/admin/awrrpt 中间没有任何空格，需要在数据库服务器上Oracle用户登陆，sqlplus / as sysdba 进入sql> 下执行.
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: //注意这里直接回车即可，默认就是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 //注意这里根据实际需要选择几天的AWR报告，一般取最近的AWR报告选择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 //注意这里输入的begin_snap 和 end_snap都是根据上面具体时间点对应的实际Snap Id那一列决定的. 比如我要选 09:00 - 10:00的话，那起始就应该是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: //这里默认回车即可，名字会有一个默认值的。
Using the report name awrrpt_1_94_95.html
此处省略大量屏幕输出..
End of Report </BODY></HTML> Report written to awrrpt_1_94_95.html sql> !pwd /home/oracle
注：生成的报告文件发送给我即可,例如此处就是指awrrpt_1_94_95.html文件，代表的是2014年10月16日10点~11点这一小时的数据库实例jy1的工作负载报告。
2.RAC的其他实例AWR报告提取：@?/rdbms/admin/awrrpti
sql> @?/rdbms/admin/awrrpti 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: 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 Enter value for dbid: 857123342 Using 857123342 for database Id Enter value for inst_num: 2 Using 2 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: 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. To use this name, press <return> to continue, otherwise enter an alternative. Enter value for report_name: Using the report name awrrpt_2_94_95.html 此处省略大量屏幕输出.. End of Report </BODY></HTML> Report written to awrrpt_2_94_95.html
3.手工生成一个快照：
exec dbms_workload_repository.create_snapshot();
sql> exec dbms_workload_repository.create_snapshot(); PL/sql procedure successfully completed.
