This article will explain in detail how to start the RAC 11.2.0.4.0 OHASD service in Oracle. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

System environment: Oracle Linux 6.6

Database version: 11.2.0.4.0

1. Close the Node 1 database instance and shut down the cluster service

[oracle@rac2] $sqlplus / as sysdba

SQL > shutdown immediate

[root@rac1 bin] #. / crsctl stop crs

2. After restarting the host, start the cluster

[root@rac1 bin] #. / crsctl start crs

CRS-4124:Oracle High Availability Services startup failed.

CRS-4000:Command Start failed,Or completed with errors.

3. Check the relevant logs. Only the ohasd.log log is shown as follows:

2018-01-19 19 OHASD00117 55 OHASD00117 59.091 [default] [1929652000] Created alert: (OHASD00117:): TIMED OUT WAITTING FOR OHASD MONITOR

2018-01-19 20 OHASD00117 16V 04.893 [default] [3020662560] Created alert: (OHASD00117:): TIMED OUT WAITTING FOR OHASD MONITOR

2018-01-19 20 OHASD00117 33 36 18 [default] [3004282656] Created alert: (OHASD00117:): TIMED OUT WAITTING FOR OHASD MONITOR

4. Check the startup process and strace the ohasd process

[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)

Boot sequence of 11g GI:

Ohasd-- > ohasd

Agents-- > daemons (gipcd, mdnsd, gpnpd,ctssd, ocssd, crsd, evmd asm etc)

Then crsd-- > crsd agents-- > user resources (database, SCAN,listener etc)

5. Delete pipe files

[root@rac1 bin] # cd / var/tmp/.oracle/

[root@rac1 bin] # rm npohasd

6. Restart GI successfully

[root@rac1 bin] #. / crsctl start crs
