To increase Tibco BusinessConnect logging on runtime in DEV & TST perform the following tasks:
Open the file log4j.properties in /bc/5.x/lib/
Set the property ‘log4j.logger.bw.logger=DEBUG’ where the default is INFO
Go to TIBCO Administrator, BusinessConnect, Interior Server.par -> Advanced Tab
set Trace.Task.* = true under ‘Edit Service Configuration’
restart the BC engines
You do not want to use these settings in a production environment due to certain performance issues.
