Ruud, I did not see a much impact from the TSM server side trace. I did see a tremendous throughput impact from the client side trace running on a NT node. I found the documentation at the following locations; TSM server: http://www.tivoli.com/support/storage_mgt/adsm/pubs/v3pubs/aix/html/adsmtrf/ cp5ect16.htm TSM client: http://www.tivoli.com/support/storage_mgr/pubs/v4pubs/v1_html/aix/trfc/anst0 007.htm Good luck, Peter Coles Pacific Gas and Electric Co. pjcg AT pge DOT com 805-545-4237
