Subject [jira] Resolved: (QPID-1664) Asynchronous notification capability
Date Sat, 14 Feb 2009 10:59:59 GMT

     [ https://issues.apache.org/jira/browse/QPID-1664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrea Gazzarini resolved QPID-1664.
------------------------------------

    Resolution: Fixed

Feature has been added. Now there's a WorkManager that can be used for send asynch notification(s).
That new component will be configured using the qman-config.xml. Therefore a new section has
been added to that configuration file in order to provide configuration for :

- Thread pool size (default : 5);
- Max Thread pool size (default 15);
- Keep Alive time (defalut 5000 millisecs);

> The current implementation of WS-Notification engine is synchronous. That means the publisher
(QMan) will remain blocked until the notification has been processed on oberserver (client)
side...this is in generarl not acceptable because a server component depends on a client behaviour...
> So, notifications should be processed in separate threads. JDK 1.5 introduced a TrheadPoolEXecutor
that is something like a WorkManager in a JEE environment. 
> Qman will use it for asynchronous notification capability.
