We are trying to move our GCG installation from an SGI Origin 200 to a
new SunFire 480 (running SunOS 5.8) and are having significant problems
with the SeqWeb installation. This is the exact same installation as
on our old SGI - GCG 10.3 (patched to 10.3.1) and SeqWeb 2.1. Access
from Windows browsers (NT, 2000 and XP - using various supported
browsers, e.g. NetScape 4.79 or 6.2) and Mac (OS 9.2 and X, NetScape
4.79, 6.2 and IE 5.2.2 and 5.2.3) has, and is working fine with the SGI
Access to SeqWeb on the Sun installation has numerous problems.
Browsers pop up multiple authentication boxes - the first two always
being Apache, and then one to as many as 8 Java authentication forms
(at least, the dialogue boxes all have the Java coffee-cup icon). Even
after persisting through the multiple login authentications, there are
still intermittent problems. For example, NetScape 4.79 on Windows
2000 will often crash as soon as one attempts to execute an analysis.
NetScape 6.2 on OS X will sometimes refresh the main SeqWeb page,
losing the main (white, centre) interactive frame, and then becoming
completely non-responsive after that. Even when one can get in long
enough to execute a program, analyses will often never return a results
page, or will render it incorrectly (especially with graphic output, as
from MapPlot, for example).
The CLI installation, and SeqLab all seem to run correctly on the Sun
machine, it is just SeqWeb access, and as I say, we have tried several
versions of supposedly supported browsers (NetScape and IE versions) on
several Windows and Mac platforms, all of which work correctly with our
SGI installation of SeqWeb. Incidentally, the Sun installation does
seem to work correctly when accessed via NetScape 4.79 from another SGI
box, and a Linux Box.
SeqWeb configuration settings on both the SGI and Sun are identical.
If anyone has every seen such behavior, or experienced problems
accessing SeqWeb on a Sun machine I would appreciate hearing from you.
It has been 3 weeks now, and most of what are hearing from Accelrys is
Thanks for any responses, Michael
