          [oracle@localhost ~]$ oerr tns 1189
          01189, 00000, "The listener could not authenticate the user"
          // *Cause: The user attempted to issue a privileged administrative command, but
          // could not be successfully authenticated by the listener using the local OS 
          // authentication mechanism. This may occur due to one of the following 
          // reasons:
          // 1. The user is running a version of LSNRCTL that is lower than the version
          //    of the listener.
          // 2. The user is attempting to administer the listener from a remote node.
          // 3. The listener could not obtain the system resources needed to perform the 
          //    authentication.
          // 4. The local network connection between the listener and LSNRCTL was 
          //    terminated unexpectedly during authentication message exchange, such as 
          //    if LSNRCTL program was suddenly aborted.
          // 5. The communication between the listener and LSNRCTL is being intercepted
          //    by a malicious user.
          // 6. The software that the user is running is not following the authentication
          //    protocol, indicating a malicious user.
          // *Action: Make sure that administrative commands are issued using the LSNRCTL
          // tool that is of a version equal or greater than the version of the listener,
          // and that the tool and the listener are running on the same node. You can 
          // issue the VERSION command to find out the version of the listener. 
          // If a malicious user is suspected, use the information provided in 
          // the listener log file to determine the source and nature of the requests. 
          // Enable listener tracing for more information. If the error persists, 
          // contact Oracle Support Services.
