Well, there is a cool tool you can download for free from Everest Software International called OneWorld Debug Log Comannder. This tool has a few cool features, but the BIG advantage with using this tool is that it allows you to turn debugging on and off "on the fly". No more having to log off and back on. No more lost time having to once again setup UTB.
I use this software everywhere I go. Download it, give it a shot, and let me know what you think.
Some other cool features are that you can clear and view the jdedebug.log and jde.log files without having to find them. You can delete the 6 DD files (log off and back on is required for this). You can clear the cache, and there is also a julian date conversion tool.
