ShengTao Dong commented on JUDDI-426:
-------------------------------------
Thanks curt, in our environment, it cause every notification fail in a period
time, for example, in 5 minutes, all notification are ignored for they all late
than right time, It's normal once a notification is ignored, further
notification will be ignored in a big possibility.
Our model is, there is a master juddi that is used to register, and there are
many local juddi those are used to be lookup, so the process is the services
will register in master juddi first, and then will be distributed to local
juddi by notification. So if in 5 minutes, all notification are ignored, all
services those register in this 5 minutes will not be distributed, and the
client want to lookup in local juddi will fail.
That's the problem.
> Could disable the check for the lag time of the notification

> Affects Versions: 3.0.1
> Reporter: ShengTao Dong
> Assignee: Kurt T Stam
>
> In the org.apache.juddi.subscription.SubscriptionNotifier class, there is
> this method:
> The value ACCEPTABLE_LAG_TIME is fixed in code and is 500ms, and could this
> be refactor to be a property that the user can set, and for some special
> value, for example '-1' will mean always notify.
> private boolean firedOnTime(long scheduleExecutionTime) {
> long lagTime = System.currentTimeMillis() - scheduleExecutionTime;
> if (lagTime <= ACCEPTABLE_LAG_TIME) {
> return true;
> } else {
> log.warn("NotificationTimer is lagging " + lagTime + " milli
> seconds behind. A lag time "
> + "which exceeds an acceptable lagtime of " +
> ACCEPTABLE_LAG_TIME + "ms indicates "
> + "that the registry server is under stress. We are
> therefore skipping this notification "
> + "cycle.");
> return false;
> }
> }
