Oracle 11G常见性能诊断报告(AWR/ADDM/ASH)收集
Oracle 11G常见性能诊断报告(AWR/ADDM/ASH)收集
原创前言：
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。
环境：
CentOS 7.5
Docker 20.10.2
Oracle_11g
AWR报告收集：
AWR(Automatic Workload Repository)自动工作负载库是Oracle公司提供的一个工具。AWR来可以自动收集、处理、并保存性能统计结果，这种统计数据存放在内存中并随后存储在数据库中，这些数据既能在报告中显示也可以通过视图查询。可以协助我们找出Oracle的性能瓶颈。

因为有的系统一般都是RAC，所以需要在各个节点下的AWR报告，如果你愿意登录各个节点，可以使用一下SQL
使用addmrpti.sql脚本：@?/rdbms/admin/addmrpt.sql
ASH报告收集：
ASH即活动会话历史，Active Session History，ASH以V$SESSION为基础，每秒采样一次，记录活动会话等待的事件。不活动的会话不会采样， 采样工作由新引入的后台进程MMNL完成。
Oracle v$active_session_history视图提供了实例中的活动会话采样。通过该视图提供的最详细最完整性能数据，可作为定位性能故障的一手证据。任一连接到数据库时，那些不属于空闲等待类的事件的会话被认为是活动会话。这包括在采样时在CPU上的任何会话。

3.1 查看oracle容器内生成的ADDM报告
[root@test ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3edfba76f476 registry.aliyuncs.com/helowin/oracle_11g "/bin/sh -c '/home/o…" 2 months ago Up 3 hours 0.0.0.0:1521->1521/tcp oracle_11g [root@test ~]# docker exec -it oracle_11g bash [oracle@3edfba76f476 /]$ su - root Password: helowin [root@3edfba76f476 ~]# su - oracle [oracle@3edfba76f476 ~]$ pwd /home/oracle [oracle@3edfba76f476 ~]$ ls addmrpt_1_254_256.txt app ashrpt_1_0421_1900.html awrrpt_1_253_255.html

3.2 导出oracle容器内部的ADDM报告至之宿主机
—》docker cp 容器ID:容器内文件路径 ./（宿主机路径）
[root@test ~]# docker cp 3edfba76f476:/home/oracle/ashrpt_1_0421_1900.html ./
- 1.
其他（RAC）：
因为有的系统一般都是RAC，所以需要在各个节点下的AWR报告，如果你愿意登录各个节点，可以使用一下SQL
@?/rdbms/admin/ashrpti.sql与上边的不同也就是需要输入DBID和实例NUMBER，明白提示的意思就行。
—注意— ：
在生成报告期间，不能有数据库重启的操作，如果有会有报错。
