Hi Mark
My best guess, although I've never seen it before, is that the
latency issue is caused by the way Oracle's JVM interacts with
Windows and Terminal Services. Craig Bender's suggestion will allow
you to test this.
If it turns out to be a problem unrelated to the Sun Rays, it may
be worth trying the Oracle Forms application using a different web
browser and/or java plugin. First step is to try using
"appletviewer" from Sun's JDK. Try both 1.4 and 1.5. If this works,
then you can create an icon on the desktop to launch appletviewer
pointing at the app URL.
You can also try launching the applet from your web browser using
the java plugin. It's been a while since I've done this, but it may
require copying the application launch page and modifying the html
so that the web browser is told to look for the java plugin instead
of jinitiator. It may even work within a web browser running on a
different operating system. Once again it's worth trying both 1.4
and 1.5.
In my experience Oracle Forms can sometimes be a bit "quirky"
running on different platforms. YMMV. If it's a showstopper, you
may need to convince the apps guys to upgrade to a more recent
Forms patch level.

Tom,
Thanks for the guidance. I believe that the problem is with the
application. Your ideas for the Oracle Forms are great. We have a lot
of experience with Sun Rays but not much with Oracle. I'll try what
Craig suggested first to narrow down the problem. If it confirms that
the application is the issue, we'll see if we can get the university
to let us experiment with the ideas you listed.
Thanks again.

We're a reseller running a small Sun Ray demonstration for a
university. It's a self contained 100 Mb network with a D-Link
router providing DHCP addresses, a Windows 2003 server running the
application and a W2100z as the Sun Ray server with SRSS 3.1 on
Solaris. Rdesktop provides the Windows connectivity. We're using
CAM mode.
The application is Jinitiator (Oracle's implementation of Sun's
JavaSoft Plug-In for Solaris). It's launched through a web browser
and they use it to access Oracle forms from the PC for a
facilities maintenance application. It's a Windows-only application.
When running from a Sun Ray 170 we're seeing slow response to
keyboard input, i.e., if you type quickly the display lags by six
to seven characters. When using other applications based on the PC
such as browsing the web or using word processing, the response is
quite satisfactory. Also when using the application directly on
the PC, this problem does not appear.
Any suggestions or ideas would be appreciated. Thanks.
Regards,
Mark
