To enable logging of input and output of all Activities, edit the tra file, located in something like /opt/tibco/tra/<domainname>/application/<adaptername>/<adaptername>-<bwenginename>.tra. Change “Trace.Task.*=false” in “Trace.Task.*=true” and add two lines at the bottom of the file:

bw.engine.showInput=true

bw.engine.showOutput=true

Finally, restart the engine.

After a (re)deployment, these changes are reverted.
