CRS-00184: Cannot communicate with the CRS daemon on Oracle RAC

Hi,

Sometimes You can get “CRS-00184: Cannot communicate with the CRS daemon ” error.

 

Details of error are as follows.

CRS-00184: Cannot communicate with the CRS daemon.
Cause: The CRS daemon on the local node is either not running or there was an internal communication error with the CRS daemon.
Action: Check if the CRS daemon process is running on the local node.

This Error is related with the Interconnect ( private ) network down, so check Private network.

 

To solve this error, stop and start the Oracle RAC services as follows.

[root@msdbadm01 ~] cd $GRID_HOME/bin
[root@msdbadm01 bin] crsctl stop cluster -all
[root@msdbadm01 bin] crsctl start cluster -all

 

And check all services if they are online or not.

[root@msdbadm01 bin] crsctl check crs

[root@msdbadm01 bin] crsctl status resource -t

[root@msdbadm01 bin] crsctl check cluster -all
