The ORA-609 error is thrown when
a client connection of any kind failed to complete or
aborted the connection process before the server process was
completely spawned. Beginning with 10gR2, a default value
for inbound connect timeout has been set at 60 seconds. This
is also triggered when a DB session is killed/aborted
manually from the OS prompt. To remove a primary ORA-609 error, you should increase the values for INBOUND_CONNECT_TIMEOUT at both listener and server side sqlnet.ora file as a preventive measure. If the problem is due to connection timeouts, and increase in the following parameters should eliminate or reduce the occurrence of the ORA-609 error. - Sqlnet.ora: SQLNET.INBOUND_CONNECT_TIMEOUT=180 - Listener.ora: INBOUND_CONNECT_TIMEOUT_listener_name=120 |
