Lsnrctl Status shows TNS-12541 "no Listener" after a few days on Linux 64 Bit but Listener is still running
(Doc ID 2251039.1)
Last updated on APRIL 03, 2017
Applies to:Oracle Net Services - Version 22.214.171.124 and later
After a few days of starting the TNS Listener, running "lsnrctl status" does not work.
Connections are working through this listener and ps -ef |grep tnslsnr shows the listener is running.
The Listener cannot be stopped and the process itself has to be killed.
This may be a new installation on Linux (for example, Redhat 7) when an original installation on Redhat 5 was working without issues.
