Hello Martin,
You are using the old, or shall we say the out of the box OSB.pbd because it has tracer mappings with com.wily.powerpack.alsb
com.wily.powerpack.alsb.tracer.BsStartTracer for plugin "Business Service Start Tracer" in extension "Oracle OSB Fieldpack 12c" loaded from "/orabin/wily/core/ext/oracle.osb.addon.jar"
The code inside oracle.osb.addon.jar has a new format
com.ca.apm.extension.alsb.tracer.BsStartTracer
You should have an updated version of the OSB.pbd in whatever package you originally got the oracle.osb.addon.jar file with, you need to replace the old OSB.pbd with the new one.
Many thanks,
David
