The TSM logfiles are indeed 500GB in size, as you noticed. Are there more than 
20? All in you activelog directory? Is this a separate, dedicated, filesystem, 
as recommended? You can increase the size of the active log by changing the 
activelogsize parameter in your dsmserv.opt, but I doubt that this will do 
anything, since DB2 is not actually using the allocated space.

What are the symptoms? Other than filling up your filesystem? Is TSM suffering 
in any way?
