最新写到目标端的数据已经是当前修改时间(这个是系统时间，肯定会修改过来)
出现Time Since Chkpt unknown，处理方法见ogg中Time Since Chkpt显示unknown解决

三、重设r_3时间点

--进程启动，工作正常

三、补充说明
1、部署ogg前需要核对两边时间是否相同，为了避免不必要的麻烦，建议配置ntp同步时间
2、这里因为我们这要求该同步上线无严格时间要求，所以通过重设r_3时间点实现工作正常，如果事情比较紧急，建议删除trail文件，重建pump和replicat进程
3、这里说明ogg同步也还不是和时间一点关系都没有

Mysql查询视图：ERROR 1449 (HY000)

1、问题重现
前几天因为有人删除了数据库中的记录，今天关闭了数据库的远程访问功能，今天接到开发报告，说出现 The user specified as a definer (‘air’@’%’) does not exist错误，他们定位是一张视图不能访问。利用实验重现了他们的情况

3、原因分析
因为创建视图使用的是xff@%用户(目前已经不存在)，然后登录用户使用的是xff@localhost用户，导致mysql认为现在的用户无权限访问该视图，解决方法就是在当前用户下重建该视图

Data pump 中network_link参数的使用续(登录用户和源端用户不一致处理)

Mysql误删除数据及其bug分析

Posted on by

一、现状描述
11月25日晚上8点40分接到现场电话，说我们公司所有员工的im不能正常登陆，im数据库服务器（mysql数据库）的公司表中对应的我们公司名称被删除，需要处理。接到这个异常后，第一想到的是下午下班前，收到一封ogg的警告邮件说ogg进程终止，然后我登陆数据库查看的时候，发现ogg已经工作正常，所以也就没有太多关注。既然已经出现了这个问题，那么先解决问题，再分析原因。因为这些都是ogg从oracle端同步过来的一些数据，所以直接从oracle那边初始化一份过来，然后重设同步程序就可以了。

二、错误分析
1、出现这个问题，第一想到的就是binlog，因为公司表的数据是从我们oracle那边同步过去的，而且oracle那边没有任何关于这个表的删除操作，所以我定位这个表的delete操作

[mysql@ezgclient mysqllog]$ mysqlbinlog mysqlbin.000150>/tmp/11_25.txt
[mysql@ezgclient mysqllog]$ vi /tmp/11_25.txt

2、因为binlog_format采用的是row模式，所以需要进一步解析binglog

[mysql@ezgclient mysqllog]$ mysqlbinlog -v -v mysqlbin.000150>/tmp/11_25.txt
[mysql@ezgclient mysqllog]$ vi /tmp/11_25.txt

通过上面的分析和这里的日志情况显示，很明显有人误删除了这条记录，导致我们公司所有员工不能登录im(登录在线的，不会使用到这条记录，这个也就是导致了我们到晚上八点多才发现这个异常)

3、检查error日志
检查这个日志，发现一个很明显的bug,这个是导致数据库重启，以及那个时间因为数据库重启导致ogg进程异常收到邮件

111125 16:15:35 InnoDB: Assertion failure in thread 1095162176 in file row/row0mysql.c line 1534

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

key_buffer_size=8388608
read_buffer_size=1048576
max_used_connections=30
max_threads=1000
threads_connected=14
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 9234379 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

而且还有个巧合就是查看binlog发现，DELETE FROM a.abc where ……之后，数据库就因为这个bug自动重启了。

---从这信息看是整理簇索引，导致表空间出现损坏
---分析的情况，你的系统应该正在做一个DELETE操作，而且应该无索引可走，删除的数据量也比较大
---可能是大量数据被缓存在innodb_buffer_pool_size中，并且其内部有创建自适应的hash索引，因删除数据而不得不重新创建，
---以及你的服务器当时IO出现瓶颈，导致一时无法响应Innodb master thread，而出现问题，并且InnoDB引擎在此方面出现过BUG
---解决版本是5.1.37之后，所以建议使用：5.1.40版本，较稳定
