I have a instance which run as MTS mode. When i startup my instance, i can see all the dispatcher (D000) and shared server process (S000, S001...) in OS level. When i query v$dispatcher, the dispatcher return everything is normal.
However, when i run "lsnrctl service", i can only see the DEDICATED SERVER status. My Dispatcher seems can't register to my Listener.
When i check the listener.log, i see
"22-JUL-2003 10:27:38 * service_died * 12537" and this error occurs once a minute !
I think there is some problem with my Listener so that it can't recognise the Dispatcher and MTS mode can't be used.
When i connect to my DB through SQL Plus, I can connect and everything is normal, but this connection is forced to be in "Dedicated Server" mode. The Dispatcher did not receive any request.
