本文档的目的是总结可能阻止 Grid Infrastructure (GI) 成功启动的 5 大问题。
本文档仅适用于 11gR2 Grid Infrastructure。
要确定 GI 的状态,请运行以下命令:
症状:
1. 命令“$GRID_HOME/bin/crsctl check crs”返回错误:
CRS-4639: Could not contact Oracle High Availability Services
2. 命令“ps -ef | grep init”不显示类似于如下所示的行:
root 4878 1 0 Sep12 ? 00:00:02 /bin/sh /etc/init.d/init.ohasd run
3. 命令“ps -ef | grep d.bin”不显示类似于如下所示的行:
root 21350 1 6 22:24 ? 00:00:01 /u01/app/11.2.0/grid/bin/ohasd.bin reboot
或者它只显示 "ohasd.bin reboot" 进程而没有其他进程
可能的原因:
解决方案:
症状:
1. 命令“$GRID_HOME/bin/crsctl check crs”返回错误:
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
2. 命令“ps -ef | grep d.bin”不显示类似于如下所示的行:
oragrid 21543 1 1 22:24 ? 00:00:01 /u01/app/11.2.0/grid/bin/ocssd.bin
3. ocssd.bin 正在运行,但在 ocssd.log 中显示消息“CLSGPNP_CALL_AGAIN”后又中止运行
4. ocssd.log 显示如下内容:
2012-01-27 13:42:58.796: [ CSSD][19]clssnmvDHBValidateNCopy: node 1, racnode1, has a disk HB, but no network HB, DHB has rcfg 223132864, wrtcnt, 1112, LATS 783238209,
lastSeqNo 1111, uniqueness 1327692232, timestamp 1327693378/787089065
5. 对于 3 个或更多节点的情况,2 个节点形成的集群一切正常,但是,当第 3 个节点加入时就出现故障,ocssd.log 显示如下内容:
2012-02-09 11:33:53.048: [ CSSD][1120926016](:CSSNM00008:)clssnmCheckDskInfo: Aborting local node to avoid splitbrain. Cohort of 2 nodes with leader 2, racnode2, is smaller than

2012-02-09 11:33:53.048: [ CSSD][1120926016]clssscExit: CSSD aborting from thread clssnmRcfgMgrThread
6. 10 分钟后 ocssd.bin 启动超时
2012-04-08 12:04:33.153: [ CSSD][1]clssscmain: Starting CSS daemon, version 11.2.0.3.0, in (clustered) mode with uniqueness value 1333911873

可能的原因:
解决方案:
症状:
1. 命令“$GRID_HOME/bin/crsctl check crs”返回错误:
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager
2. 命令“ps -ef | grep d.bin”不显示类似于如下所示的行:
root 23017 1 1 22:34 ? 00:00:00 /u01/app/11.2.0/grid/bin/crsd.bin reboot
3. 即使存在 crsd.bin 进程,命令“crsctl stat res -t –init”仍然显示:
ora.crsd

可能的原因:
解决方案:
症状:
1. orarootagent 未运行. ohasd.log 显示:
2012-12-21 02:14:05.071: [ A**][24] {0:0:2} Created alert : (:CRSAGF00123:) : Failed to start the agent process: /grid/11.2.0/grid_2/bin/orarootagent Category: -1 Operation: fail Loc: canexec2 OS error: 0 Other : no exe permission, file [/grid/11.2.0/grid_2/bin/orarootagent]
2. mdnsd.bin, gpnpd.bin 或者 gipcd.bin 未运行, 以下是 mdnsd log中显示的一个例子:
2012-12-31 21:37:27.601: [ clsdmt][1088776512]Creating PID [4526] file for home /u01/app/11.2.0/grid host lc1n1 bin mdns to /u01/app/11.2.0/grid/mdns/init/

症状:
1. 命令“ps -ef | grep asm”不显示 ASM 进程
2. 命令“crsctl stat res -t –init”显示:
ora.asm
