| ERROR | The listener has not recognized the password |
| CAUSE | The listener has the password security mechanism enabled and requires the correct password to execute any command other than VERSION. The user attempted to issue one of the privileged administrative commands, but could not be successfully authenticated with the password provided. |
| ACTION | If an authorized user is attempting the command, then use the SET PASSWORD command at the LSNRCTL prompt with the listener password. If you do not know the password, then you are trying to execute an inappropriate command. |
