可以设置文件名,报告分析之后:我们可以在浏览器中查看报告(这里列出了数据库的整体运行情况,执行时间长的前几条SQL,参数文件,等等,注意AWR只是一个报告,并不会帮助我们分析该如何优化,在后面的ADDM报告则会为我们提供优化的建议):


--======================================================================
另外有一种addm报告会帮助我们分析,并且提供必要的调优建议:

DETAILED ADDM REPORT FOR TASK 'TASK_1814' WITH ID 1814
          ------------------------------------------------------

              Analysis Period: 19-MAY-2013 from 13:30:50 to 14:00:57
         Database ID/Instance: 1326384392/1
      Database/Instance Names: ORCL/orclsid
                    Host Name: localhost.localdomain
             Database Version: 10.2.0.1.0
               Snapshot Range: from 226 to 227
                Database Time: 11 seconds
        Average Database Load: 0 active sessions

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

THERE WAS NOT ENOUGH DATABASE TIME FOR ADDM ANALYSIS.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

          ADDITIONAL INFORMATION
          ----------------------

There was no significant database activity to run the ADDM.

The database's maintenance windows were active during 99% of the analysis
period.

The analysis of I/O performance is based on the default assumption that the
average read time for one database block is 10000 micro-seconds.

An explanation of the terminology used in this report is available when you
run the report with the 'ALL' level of detail.
