Dispatchers Fail to Register Dynamically Against the Listener (Doc ID 889092.1)

Last updated on MARCH 31, 2022

Applies to:

Oracle Net Services - Version to [Release 10.2 to 11.1]
Information in this document applies to any platform.
This problem can occur on any platform.
This document applies to versions 10g and newer.


Dispatchers are spawning but failing to register against the listener following this command:

Lsnrctl services output does not show any dispatchers have been registerered. However, a check of ps -ef | grep D000 shows that dispatcher processes have spawned.

The listener is running on the default port of 1521 and LOCAL_LISTENER and REMOTE_LISTENER are set correctly.


This is a new implementation of shared server.  This database has previously been running in dedicated server mode.
