Profile说明：
ICX:Session Timeout
This profile option determines the length of time (in minutes) of inactivity in a user‘s session before the session is disabled. If the user does not perform any operation in Oracle Applications for longer than this value, the session is disabled.
The user is provided the opportunity to re-authenticate and re-enable a timed-out session. If the re-authentication is successful, the disabled session is re-enabled and no work is lost. Otherwise, Oracle Applications exit without saving pending work.
If this profile option to 0 or NULL, then user session will never time out due to inactivity.
Users can see this profile option, but they cannot update it.
The internal name for this profile option is ICX_SESSION_TIME_OUT.
