关于Disk file operation IO的一个案例分析

最近某银行新核心上线，我司同事连续奋战了大半年，真不容易。在此为大家的辛苦付出点赞。上线后，用户的EM监控突然来了一个告警；

最开始以为是个简单的问题，因此就简单查询了一下ash数据，发现主要是一个SQL语句上：

1151 3wybn83gkuc4k oracle@mccsdb01 (PPA7)         Disk file operations I/O   8 FileOperation  8 filetype  2020-06-15 14:39

该SQL的代码如下：

SELECT TO_CHAR(current_timestamp AT TIME ZONE 'GMT',
               'YYYY-MM-DD HH24:MI:SS TZD') AS curr_timestamp,
       SUM(failed_count) AS failed_count,
       TO_CHAR(MIN(first_occur_time), 'yyyy-mm-dd hh24:mi:ss') AS first_occur_time,
       TO_CHAR(MAX(last_occur_time), 'yyyy-mm-dd hh24:mi:ss') AS last_occur_time
  FROM (SELECT COUNT(db_user) AS failed_count,
               MIN(extended_timestamp) AS first_occur_time,
               MAX(extended_timestamp) AS last_occur_time
          FROM sys.dba_common_audit_trail
         WHERE action BETWEEN 100 AND 102
           AND returncode != 0
           AND STATEMENT_TYPE = 'LOGON'
           AND extended_timestamp >=
               current_timestamp - TO_DSINTERVAL('0 0:30:00')
        UNION
        SELECT COUNT(DBUSERNAME) AS failed_count,
               MIN(event_timestamp) AS first_occur_time,
               MAX(event_timestamp) AS last_occur_time
          FROM unified_audit_trail
         WHERE ACTION_NAME = 'LOGON'
           and return_code <> 0
           AND event_timestamp >=
               current_timestamp - TO_DSINTERVAL('0 0:30:00'))

从代码来看，这是一个跟审计相关的SQL语句。第一直觉是这个SQL执行效率可能不高；但是其出现的等待事件是IO相关。因此用户非常关系是不是系统IO有问题？如何判断IO是否有问题呢？其实我们可以通过脚本发现查询相关event的平均IO等待事件时间即可：

----and SAMPLE_TIME = to_Date('2020-06-15 15:09','yyyy-mm-dd hh24:mi')
---group byinst_id,event,to_char(SAMPLE_TIME,'yyyy-mm-dd hh24:mi'),p1,p3
order by 1,3,5;

BTIME                    EVENT_NAME                        AVG_MS           CT

如果说上述信息还不足以证明的话，那么其实可以查看awr报告的直方图信息：

我们知道Oracle为了确保安全性，实现的是日志写优先原则；每一笔事务的提交，Oracle lgwr进程都必须将对应的日志刷新到磁盘；因此可以通过lgwr 进程的写操作来判断数据库主机到存储之间的链路和存储IO是否正常。很明显，从上述图表来看，lgwr file parallel write没有超过8ms的等待。因此可以排除链路和存储的问题。

最开始由于怀疑是SQL问题，尝试收集了几个表的统计信息之后，运行了一下SQL，都在秒级能够返回结果，以为解决了问题。没想到，第二天监控又爆出来了。仍然是相同的问题告警。

这是我再次回馈到分析这个sql的执行计划，该执行计划如下所示：

再次回归到分析SQL执行计划，我们发现该SQL的视图中访问的几个表在之前都进行了检查，数据量非常小，而且执行计划本身并没有问题。唯一的可能疑点是对于X$XML_AUDIT_TRAIL 的访问。在之前的分析中，由于检查数据库审计设置，发现已关闭了数据库审计，因此忽略了这个疑点。

通过进行单次多次测试发现，基于X$XML_AUDIT_TRAIL的访问时非常慢的；而且每次访问都会出现Disk file operation IO等待。如下所示：

而上述的d0k3ahnmyd2a2 则是我的测试SQL语句：

SYS@mccs1>select sql_text from v$sql where sql_id='d0k3ahnmyd2a2';

SQL_TEXT
------------------------------------------------------------------------------------
select count(1) from X$XML_AUDIT_TRAIL

Elapsed: 00:00:00.01
SYS@mccs1>

从验证来看，看来问题出现这个xml的表上。我们知道Disk file operation IO等待表示的对于文件的操作，比如open，close等。而且前面查询event的operation type都是8，表明确实在等待IO。那么这里的IO是不是物理IO呢？

Stat Name	Statement Total	Per Execution	% Snap Total

Sharable Mem(KB)	804

从上面的SQL report来看，其实该SQL并没有产生物理读。都没有产生物理IO，为什么是IO相关的等待呢？这就奇怪了。。。

那么唯一的解释就是该SQL可能会访问系统的文件，因为用到了xml。联想到这一层，那么怎么验证这个猜想呢？这里我分别开启2个crt窗口进行测试跟踪即可：

++Session 1

SYS@mccs1>c/9/8
  1* select  count(8) from X$XML_AUDIT_TRAIL
SYS@mccs1>/

  COUNT(8)
----------
         0

Elapsed: 00:00:08.20
SYS@mccs1>

可以看到该SQL查询花费了8.2秒。

从上的跟踪信息来看；我们的测试SQL语句执行时间为8.2秒，其中从_poll函数开始到close(12)操作截止，就消耗了8.19秒。其中getdirent64函数操作就消耗了8.14秒。该函数表现获取文件系统目录和文件信息；同时从close的句柄操作来看，主要是慢在/adump目录的操作上。这也难怪上述SQL执行为什么会这么慢了。而且每次执行必然会出现Disk file operation IO等待。

进一步检查/adump目录发现，该目录下的小文件居然高达263万个。

[oracle@xxxxdb01:/u01/app/oracle/admin/xxxx/adump]$ls|wc -l
 2634022

到这里问题基本上就非常清晰了。只要清理这个目录的垃圾文件即可。

那么问题就来了，数据库都已经关闭了审计，为什么还会产生这么多文件呢？实际上大概估算一下，该系统从去年安装部署后至今，大概也就200多天；也就是说该目录平均每天增加1万多个小文件。其实这是因为Oracle数据库默认情况下仍然会审计sys的登陆操作。其他业务用户的审计操作均已关闭。

换句话讲，也就是说该系统的sys用户登陆每天高达1w+次。这是什么神操作呢？

最好检查crontab发现是用户有一个清理日志的脚本，忘记注释了，而该脚本几乎是每秒登陆一次（实际上大概是2-3秒）。也就就解释了为什么每天产生12000个左右的文件了。
