i'v installed oracle920 on redhat ad2.1,and i can use oracle manage server through user "sysman",
on the other hand, i installed oracle920's client on win2000,and i also can connect to the redhat oracle server through standalone
the problem is that:
when i connect to the redhat oracle server through oracle manage server,it appears:
java lang nullpointerexception errors
