###################

when a client tries to connect to the database the connection request passes through the listener. The listener may be servicing several different databases i.e. RAC and NON RAC.

By default, the Oracle Net listener notifies Cluster Ready Service (CRS) when it is started or stopped. These notifications allow CRS to manage the listener in an Oracle Real Application Clusters environment.

In Standalone Non RAC Environment above messages would be logged  since these databases are non RAC and not registered in crs.
