RAC等待事件ges inquiry response
数据库中大量出现ges inquiry response 等待事件vent Waits Time(s) Avg wait (ms) % DB time Wait Class
DB CPU 18,228 43.17
ges inquiry response 49,384,771 13,890 0 32.89 Other

大约就是这样,目前看来产生的原因是开发人员大量使用dblink进行分布式事务处理造成的回滚造成了大量的ges inquiry response ,请问大神关于该等待的详细信息,还有就是如何解决这个问题啊=。= 请上传完整的AWR、ASH、ADDM报告,缺一不可! Liu Maclean(刘相兵 发表于 2012-12-25 16:35 static/image/common/back.gif

好的,As you wish,大师,给瞧瞧吧,问了好多人了。 怀疑存在较严重的hang ,做一个systemstate dump 266给我
oradebug setmypid
oradebug unlimit
oradebug dump systemstate 266;
oradebug tracefile_name;

这几个我都看了下,目前数据库无性能问题正常使用,但是这等待事件出现比例异常,应该不是数据库hang了吧? 该 ges inquiry response 甚至不属于cluster wait,其等待类别为other
正常情况下 是不会出现的,出现一般是BUG或HANG,需要更多TRACE具体分析。 Liu Maclean(刘相兵 发表于 2012-12-25 22:00 static/image/common/back.gif

那需要怎么处理呢,分析哪些trace? 1. systemstate dump 如4楼
2. LMS进程的trace
3. 该现象是否能够重现? Liu Maclean(刘相兵 发表于 2012-12-26 09:09 static/image/common/back.gif

2. LMS进程的trace
该等待都是“ora_reco_数字”用户进行的分布式事务回滚的等待,其他的session不会出现这个。
平时进行systemstate dump看不出啥来。
现象一直有,但是得看是否出现分布式事务回滚,没有的话不出现,有的话一个session就会有几万到几十万的等待。 odm finding:
