Hi List, We have Oracle 8.1.7, SunOS 5.8, SunFire 280r. While using dbastudio and trying to add a database to the tree, no dialog box opened to allow this operation. I previously (some weeks before) have used dbastudio without any problems and have added several databases to the tree but this time no luck.I checked the output on the x-session window that was running dbastudio and the following information was displayed (please see below). I have asked out SA what has changed on our system and he says nothing ! (ie no patches, no different versions of java etc) I have trawled the web for some help on this but to no avail. If anyone has come across this problem before I would welcome any assistance. Thanks in advance, Ron.
