and alert address can be created by end users through Wireless Edition 
personalization from the desktop computer or the device.
Services in Wireless Edition can be invoked through the HTTP protocol and through 
SMS. Users can invoke the services through SMS with the corresponding service 
name. However, currently only services without input arguments can be invoked 
through SMS. The result of the service execution is returned as another SMS. The 
capability is provided through the SMS Request Listener. [[Is this still true?]]
3.2 Alerts
Alerts, which are time-based scheduled services, are placed in the request queue 
when they are created. The result of the alert execution, if any, is placed in the 
notification queue. The alert functionality in the Wireless Edition requires the 
installation of the Oracle8i JOB and AQ options.
3.2.1 Request Queue
The request queue stores all the alerts to be executed. The Wireless Edition 
processes an alert as follows:
1.
An alert is created or updated with a start date and a specified interval when 
the user creates a time-based scheduled service. The alert is placed in the 
request queue.
2.
When the specified time expires, the alert is activated and executed. The result, 
if any, is placed in the notification queue with the alert creator’s default alert 
address. The alert with an updated next execution time is placed back in the 
request queue.
3.
If the alert fails to be executed for any reason, the alert is not placed back in the 
request queue. It can only be reactivated by updating the start date through the 
Personalization Portal.
Important:
The aq_tm_processes parameter in the init.ora file 
must be set to at least "2" for the processing of asynchronous alerts 
in Wireless Edition.
