Oracle 11gR2光钎链路切换crs服务发生crash
Oracle 11gR2光钎链路切换crs服务发生crash
背景:
我们将Oracle 11gR2(11.2.0.4)在RedHat EnterPrise 5.8上通过RDAC完毕的多路径链路冗余。在部署完毕后，我们须要做多路径链路冗余測试，我们的光钎链路连接方式例如以下。我们做多路径測试完毕了例如以下几个组合：
拔线測试组合一：
1、 先拔下光钎链路 ②和④ 一切正常没有问题。插上五分钟后运行第2步。
2、 再拔下光钎链路 ①和③ 数据库服务正常，crs进程crash无法訪问。手工重新启动crs进程就可以。
拔线測试组合二：
1、 先拔下光钎链路 ①和③ 一切正常没有问题；插上五分钟后运行第2步。
2、 再拔下光钎链路 ②和④ 数据库服务正常。crs进程crash无法訪问。手工重新启动crs进程就可以。
拔线測试组合三：
1、 先拔下光钎链路 ①和④ 一切正常没有问题；插上五分钟后运行第2步。
2、 再拔下光钎链路 ②和③ 一切正常没有问题；
拔线測试组合四：
1、 先拔下光钎链路 ②和③ 一切正常没有问题；插上五分钟后运行第2步。
2、 再拔下光钎链路 ①和④ 一切正常没有问题；
控制器切换測试组合：
1、 进入存储管理控制台。查看当前磁盘所在控制器为A控，手动所有切换到B。一切正常没有问题。
2、 五分钟之后。再次进入存储管理控制台。将全部磁盘从B控制器切换到A控制器，一切正常没有问题。

问题现象:
问题发生在第一组和第二组的的測试2上面，问题现象例如以下:

故障处理有两种方法：
多路径切换层面，參考例如以下:
FailOverQuiescenceTime:
Quiescence Timeout before Failover (Mode Select Page 2C) command. Thetime,in seconds,the array will wait for a quiescence condition to clear for an explicitfailover operation. A typical setting is 20 seconds.
FailedPathCheckingInterval:
This parameter defines how long (in seconds) the MPP drivershould wait before initiating a path-validation action.Default value is 60 seconds.

ASM检測时间方面：
仅仅须要调整ASM隐含參数 _asm_hbeatiowait的值将其调大些，我这直接调到120了，又一次运行五组測试。问题没有再现，故障解决。
（參看隐含參数值得方法參考:archive-1980）
