[EN] Do not delete /tmp/.oracle or /var/tmp/.oracle folder contents

Today our RMAN backups suddenly started to get the following errors on a specific server.



RMAN-06900: WARNING: unable to generate V$RMAN_STATUS or V$RMAN_OUTPUT row
RMAN-06901: WARNING: disabling update of the V$RMAN_STATUS and V$RMAN_OUTPUT rows
ORACLE error from target database:
ORA-29701: unable to connect to Cluster Synchronization Service
 When we check the status of the css, we saw the following warning:

[oracle@hostx:/home/oracle:]crsctl stat res -t
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Status failed, or completed with errors. 




Also the following warnings in asm alertlog:

Some notes on metalink say that this could be due to cleanup of /tmp/.oracle or /var/tmp/.oracle folders. We checked our /tmp/.oracle folder and it was completely empty. One of our system admin deleted everything to get some space.

To solve this problem just restart oracle clusterware.
crsctl stop has [-f]  --use -f if it does not stop gracefully.
crsctl start has
