TNS-01189 During Listener Monitoring Using Enterprise Manager

Time:2021-3-6

oracle 12.2 RAC
Error in monitoring log:
15-JAN-2020 22:27:53 * (CONNECT_DATA=(COMMAND=VERSION)) * version * 1189
TNS-01189: The listener could not authenticate the user

BUG: 20476343

Solution

1) The workaround for this issue is to set the following listener.ora file parameter:  IP=V4_ONLY

Example:

LISTENER =
   (DESCRIPTION_LIST =
       (DESCRIPTION =
          (ADDRESS = (PROTOCOL = IPC)(KEY = ))
          (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521)(IP=V4_ONLY))
        )
     )

 Following this change, a LSNRCTL stop and start would be necessary.

This
issue is fixed in versions 12.1.0.2 and 12.2. At the time of this
writing, there are interim patches available for lower versions where
this problem might be present.

2) Add the following lines to the GRID_HOME/network/admin
listener.ora for all the nodes in the RAC, stop and start all the
listeners

LOCAL_OS_AUTHENTICATION_=off
LOCAL_OS_AUTHENTICATION_LISTENER_SCAN1=off
LOCAL_OS_AUTHENTICATION_LISTENER_SCAN2=off
LOCAL_OS_AUTHENTICATION_LISTENER_SCAN3=off
