I see this message in my error
stack (alert log) indicating an ORA-609 error. What is the
nature of the ORA-609 error?
What is the solution for the ORA-609 error?
ORA-609 : opiodr aborting process unknown
In your case, the ORA-609 is a "secondary" error, a result of the
TNS-12560 error. Other secondary errors for the ORA-609
error include a locked SYSTEM user, of any other events that prevent
a client connection, such as a failed network device.As a general error, the ORA-609 error indicates that a
client connection failed to complete. This can be an
ORA-609 from an abort or killing an Oracle session. To diagnose any error, you
start by using the
oerr utility to display the ORA-609 error:
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.
- Listener.ora: INBOUND_CONNECT_TIMEOUT_listener_name=120Do additional details on the ORA-609 error, see MOSC note
