Clusterware Intermittently Hangs And Commands Fail With CRS-184 as Network Socker Files in /tmp/.oracle or /var/tmp/.oracle Gets Deleted (文档 ID 370605.1)

APPLIES TO:

Oracle Database - Enterprise Edition - Version 10.1.0.2 to 11.1.0.7 [Release 10.1 to 11.1]
Information in this document applies to any platform.

SYMPTOMS

CRS hangs intermittently

crs_stat -t  returns

CRS-0184: Cannot communicate with the CRS daemon.

node1 [crs]> crsctl check crsd
Cannot communicate with CRS
node1 [crs]> crsctl check css
Failure 1 contacting CSS daemon

ps -ef |grep d.bin will give you the pid of the process 

for example

ps -ef |grep d.bin
oracle   19703 19281  0 Apr10 ?

        00:01:03 /home/oracle/oracle/product/10.2.0/crs/bin/evmd.bin
oracle   19976 19950  0 Apr10 ?        00:06:47 /home/oracle/oracle/product/10.2.0/crs/bin/ocssd.bin
root     19323     1  0 Apr10 ?

        00:08:47 /home/oracle/oracle/product/10.2.0/crs/bin/crsd.bin

CAUSE

This is caused by a cron job that cleans up the /tmp directory which also removes the Oracle socket files in /tmp/.oracle

SOLUTION

Do not remove /tmp/.oracle or /var/tmp/.oracle or its files while Oracle Clusterware is up.
