CRS-4124: Oracle High Availability Services start failed
CAUSE：
Install of Clusterware fails while running root.sh on OL7 - ohasd fails to start (Doc ID 1959008.1)
In OL7 it needs to be set up as a service and patch fix for Bug 18370031 needs to be applied for this , BEFORE you run root.sh when prompted .
Need to apply the patch 18370031 for 11.2.0.4 .
And also its mentioned in 11gR2 Release Notes:https://docs.oracle.com/cd/E11882_01/relnotes.112/e23558/toc.htm#CJAJEBGG
WORKAROUND:
Clear all sockets under /var/tmp/.oracle or /tmp/.oracle if any and then open two terminals of the same node, where stack is not coming up.
-
On Terminal 1 , issue as Root user :
crsctl start crs -
Simultaneously , open another terminal of the same node and issue the below command as Root user once the npohasd socket has been created.
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 -
Now if you check on terminal 1 , the CRS stack would start coming up.
ps -ef |grep d.bin
- Once entire CRS stack is up, you can press CTRL+C and come out of the dd command running on 2nd terminal.
Check and validate all resources are online using
crsctl stat res -t
crsctl stat res -t -init
WORKAROUND-2
