基于10.2.0.1 rac deadlock死锁 trace file分析_增补二
结论
1,oracle 10g rac如果在2个节点间发生死锁，会记录到告警日志中2,从告警日志可以找到对应的死锁的TRACE FILE
3，死锁的TRACE FILE内容构成
第一部分：
略去，因为和死锁内容无关
第二部分：
这是我们基于RAC死锁最为关心的信息
*** 2015-11-09 22:04:01.002

Current SQL Statement:

小结下：第二部分包括死锁会话的一些相关信息，即死锁会话SID及进程号以及终端信息，还在正在执行的SQL
第三部分：
----可见如下on [0xa0006][0x7c],[TX] 含义为[0xa0006]对应xidusn+xidslot，而0x7c]对应xidsqn

小结：
重点关注上述的信息：ENQUEUE DUMP REQUEST: from 1.22803 on [0xa0006][0x7c],[TX] for reason 3 mtype 0，对应等待者会话的XID相关的信息，即发生死锁会话的XID
至于其它信息，过于INTERNAL，还需要研究
第四部分
可见global blockers dump start即死锁的持锁者事务的信息为如下信息：
即res [0x110022][0x11],[TX]对应持锁会话,具体为res [0x110022]对应xidusn + xidslot,而[0x11]对应xidsqn
也就是可以根据如下，把16进制转换为10进制，然后到GV$TRANSACTION去匹配对应的会话，最终由GV$SESSION找到持锁会话的信息，进行针对性处理即可

小结下：
这部分可以理解为引发死锁的会话及进程的相关信息，重点关注如下信息
Global blockers dump start:---------------------------------
DUMP LOCAL BLOCKER/HOLDER: block level 5 res [0x110022][0x11],[TX]
对应即res [0x110022][0x11],[TX]对应持锁会话,具体为res [0x110022]对应xidusn + xidslot,而[0x11]对应xidsqn
也就是说先在TRAC FILE查找Global blockers dump start,然后对应的res相关的信息
然后根据res的信息如下，把16进制转换为10进制，然后到GV$TRANSACTION去匹配对应的会话，最终由GV$SESSION找到持锁会话的信息，进行针对性处理即可
关于第四部分，定位到引发死锁的持锁会话的相关信息脚本如下：
SQL> select inst_id,saddr,sid from gv$session where sid in (133,147);
INST_ID SADDR SID
---------- ---------------- ----------
1 0000000083B4FE90 133
1 0000000083B619A0 147
2 0000000083B619A0 147
SQL> select inst_id,xidusn,xidslot,xidsqn,ubafil,ubablk,ubasqn,ubarec from gv$transaction where ses_addr in ('0000000083B4FE90','0000000083B619A0');
INST_ID XIDUSN XIDSLOT XIDSQN UBAFIL UBABLK UBASQN UBAREC

SQL> select inst_id,ses_addr from gv$transaction where xidusn=12 and xidslot=16 and xidsqn=21;
INST_ID SES_ADDR

2 0000000083B619A0
SQL> select inst_id,sql_id from gv$session where saddr='0000000083B619A0' and inst_id=2;
INST_ID SQL_ID
---------- -------------
2 b3tmrc0st5pyb
可见最终定位到了引发死锁的所属实例及会话信息，即执行的SQL
SQL> select sql_text from gv$sql where sql_id='b3tmrc0st5pyb' and inst_id=2;
SQL_TEXT
--------------------------------------------------
update t_lock set a=11 where a=1
4，检测基于RAC的死锁是由lmd进程负责
[oracle@jingfa1 bdump]$ ps -ef|grep lmd
oracle 4001 1 0 Nov09 ? 00:00:09 ora_lmd0_jingfa1
oracle 29844 29669 0 00:59 pts/3 00:00:00 grep lmd
5,基于RAC的死锁检测在前端报错和单实例一样，但是在告警日志报销有所区别，内容如下：
Tue Nov 10 00:16:26 2015
Global Enqueue Services Deadlock detected. More info in file
/u01/app/oracle/admin/jingfa/bdump/jingfa1_lmd0_4001.trc.
引申：也就是说GES是负责RAC的全局锁相关的内容
6，如果要深入理解基于RAC的死锁，一定要研究进程LMD及GES的含义
7，感觉在RAC环境死锁检测时间将近30多秒，比较久，我分析有个参数控制，将于下文继续研究
测试
--oracle version

模拟死锁的代码略
在告警日志出生死锁信息

分析死锁信息,分析及注释直接标记在TRACE FILE上面
