LSNRCTL Commands May Yield Frequent TNS-1189 Errors (Doc ID 285439.1)

Last updated on JUNE 15, 2023

Applies to:

Oracle Net Services - Version and later
Information in this document applies to any platform.

The issue documented here is limited to the version 10g or higher listener or lsnrctl utility.


When using a 10g listener or higher, it is possible that the error TNS-1189 "The listener could not authenticate the user" may occur intermittently (or very frequently) while performing listener operations from within the same LSNRCTL session.  For example:

LSNRCTL> set trc_level 16

LSNRCTL> save_config



The listener.ora file may have been edited recently or this is a new installation.
