The official documents are described as follows:

3 Installing Oracle Grid Infrastructure and Oracle Real Application Clusters

Caution:
After installation is complete, do not remove manually or run cron jobs that remove/tmp /. oracle or/var/tmp /. oracle directories or their files while Oracle software is running on the server. if you remove these files, then the Oracle software can encounter intermittent hangs. oracle Clusterware installations can fail with the error:
CRS-0184: Cannot communicate with the CRS daemon.

After the installation is complete, you cannot manually move or delete/tmp/under the normal running RAC /. oracle,/var/tmp /. oracle, if removed, will cause intermittent hang, oracle cluster software will also report an error.

Remember:

If RAC is running, do not delete it!


If the file is deleted, the CRS will be created again automatically!


If the directory is deleted, you can only refer to the following command to recreate it.


Create the/var/tmp and/var/tmp/. oracle directory:


/Bin/mkdir-p/var/tmp/. oracle
/Bin/chmod 01777/var/tmp/
/Bin/chown root/var/tmp/
/Bin/chmod 01777/var/tmp/. oracle
/Bin/chown root/var/tmp/. oracle
