简介:Oracle 11G常见性能诊断报告(AWR/ADDM/ASH)收集 前言: 在生产环境中,当运行中的Oracle数据库出现性能问题的时候,DBA通常都需要我们生成Oracle数据库出现性能问题时间段的AWR或者ASH等报告来判断原因,所以维护人员学会收集AWR、ADDM、ASH报告是必须的。
注:Oracle把执行计划采样数据从V$sql_plan搬到AWR Repository基表wrh$_sql_plan中没有保留谓词信息的记录。 3、 AUTOTRACE开关 可以额外观察到目标SQL执行时所耗费的物理读、逻辑读、产生redo数量以及排序的数量。(statistics) set outotrace on; set outotrace off; ...
二、AWR报告 由oracle的两份快照而产生的差异报告,通常一小时一次,问题情况下可通过手动生成,缩小分析问题时段的范围 一般可在问题出现时以及几分钟后,各运行exec dbms_workload_repository.create_snapshot一次 SQL>execdbms_workload_repository.create_snapshot; ...
Now that we have these figures explained, let’s compare them to what we see in the Instance Activity Stats section of the same AWR report: Instance Activity Stats-> Ordered by statistic nameStatistic Totalper Secondper Trans --- --- --- ---physical read IO requests 1,848,576 513.3 12...
