Charles,
from what I could get, the issue is with the JVM, it seems that it does not
allow symbolic links when paths are used in a some types of classes (JNI
interfaces, it seems, but I'm not a Java guy, so cannot really verify or
explain much).

As Ghassan Salem pointed out, and as many of you probably already know, Oracle Application Server is not supported on symbolic links. In the process of getting over my complete disbelief in this premise, I have to ask if anyone out there knows the technical reasons for this? My linux sysadmin has these questions that I would love to know the answers to myself:
<br><br>Which kernel operation are they saying can distinguish between a symlink &amp; a directory?<br>Will we be able to revert this change once we're done?<br>Will the other machines that have /u01 need the same change?
