TNS-01106: Lsnrctl Utility Fails to Start a Second Listener
(Doc ID 352143.1)
Last updated on JANUARY 22, 2020
Applies to:Oracle Net Services - Version 10.2.0.1 to 220.127.116.11 [Release 10.2 to 12.1]
Information in this document applies to any platform.
Lsnrctl start fails with the following error:
TNS-01106: Listener using listener name LISTENER has already been started.
The listener.ora file might be configured with a duplicate IPC KEY or a duplicate TCP port number.
If the TCP Address configuration shows a HOST field containing a hostname, versus an IP address,
this error would still be expected.
Attempting to start both listeners configured like this would yield a TNS-01106 TNS: Listener using listener name % has already been started.
This is likely a new installation OR the addition of a new listener on this server.
