【Oracle】RAC 11.2.0.4.0 OHASD服务无法启动

原创 Oracle 作者:dmcatding 时间:2018-01-22 16:47:56 0 删除 编辑
系统环境:Oracle Linux 6.6
数据库版本:11.2.0.4.0
1、关闭节点1数据库实例,关闭集群服务;
[oracle@rac2]$sqlplus / as sysdba
SQL>shutdown immediate
[root@rac1 bin]#./crsctl stop crs

2、重启主机后,启动集群
[root@rac1 bin]#./crsctl start crs
CRS-4124:Oracle High Availability Services startup failed.
CRS-4000:Command Start failed,Or completed with errors.

3、检查相关日志,只有ohasd.log日志显示如下:
2018-01-19 19:55:59.091 [default][1929652000]  Created alert  :(OHASD00117 :)  :   TIMED OUT WAITTING FOR OHASD MONITOR
2018-01-19 20:16:04.893 [default][3020662560]  Created alert  :(OHASD00117 :)  :   TIMED OUT WAITTING FOR OHASD MONITOR
2018-01-19 20:33:30.618 [default][3004282656]  Created alert  :(OHASD00117 :)  :   TIMED OUT WAITTING FOR OHASD MONITOR

4、检查启动进程,对ohasd进程进行strace
[root@rac1 bin]#ps -ef|grep ohasd.bin
root 27319       1  0  21:19   ?     00:00:00 /u01/11.2.0/grid/bin/ohasd.bin reboot
root 29575   27064 99  21:23  pts/3  625-09:43:00 grep ohasd.bin

[root@rac1 bin]#strace -p 27319 -o ohasd.log

[root@rac1 bin]#cat ohasd.log
Process 27319 attached  - interrupt to quit
open("/var/tmp/.oracle/npohasd",O_WRONLY


11g GI的启动顺序:
ohasd-->ohasd
agents-->daemons (gipcd, mdnsd, gpnpd,ctssd, ocssd, crsd, evmd asm etc),
然后 crsd-->crsd agents--> user resources (database, SCAN,listener etc)

5、删除管道文件
[root@rac1 bin]#cd  /var/tmp/.oracle/
[root@rac1 bin]#rm npohasd

6、重新启动GI成功
[root@rac1 bin]#./crsctl start crs
