Applies to:Oracle Net Services - Version: 10.2.0.1.0 to 184.108.40.206
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:
ALTER SYSTEM SET DISPATCHERS='(address=(protocol=tcp)(host=myserver))(dispatchers=2)' scope=both sid='instance_name';
Additionally, the "alter system register" command has no effect.
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.
