وانا اتصفح موقع اوراكل دخلت وقرات عن الفورمز الجديد والذي اطلق عليه اسم Oracle Fusion Middleware 11g.
وما فيه من ميزات جديدة ولعل اهم الميزات التي قراتها هي كالتالي :

A new trigger called WHEN-EVENT-RAISED fires when Forms is notified about an event to

which it is subscribed, and the developer

To make it possible to execute the trigger and propagate the consequences of that trigger to the
client when the client is idle, a new application property called MAX_EVENT_WAIT has been
introduced. Developers can use MAX_EVENT_WAIT to specify, in milliseconds, how long the
maximum delay is between when an event is raised and when its effects are propagated.

It's now possible, through Forms code, to interact with JavaScript code in the page in which the
Forms applet is embedded. You do that with the help of two new additions to the built-in
package named web.


Oracle Forms can react to a call from an external JavaScript call by writing something like this in
the WHEN-CUSTOM-JAVASCRIPT-EVENT trigger

:

declare
event_val varchar2(300):= :system.javascript_event_value;
begin if (:system.javascript_event_name='show') then
handleShowEvent(event_val);
elsif(:system.javascript_event_name='grab') then
handleGrabEvent(event_val);
else
null;
end if;
end;

Making use of the Proxy User functionality



Integration with Reports
In 10g, the Forms Runtime Process created a separate JVM before calling Oracle Reports and
Reports used this JVM to execute the report. The JVM was part of the Forms Runtime Process.
In 10g, the JVM pooling feature was used only by the Java Importer. In version 11g of Oracle
Forms Services, Forms can use the shared JVM controller for Oracle Reports requests as well,
substantially reducing memory consumption.
When using JVM pooling, a process called JVM controller is



Conclusion
With the new features in Oracle Forms developers are further aided to be able to evolve and
modernize their Forms applications through technolgies such as Advanced Queueing, JavaScript,
Java and Enterprise Manager/Grid Control
