I recently have been working to update our system agents on Windows and AIX to version 12.0. I have noticed that when a job is submitted to one of these agents the following are not populated, User(...) MFUser(...), These were populated in v11.4
Release : 12.0
Component : WORKLOAD AUTOMATION System Agent
This was an enhancement in R12 to hide the credentials.
Please add the following parameter to your agentparm.txt file and restart the services.
log.credentials=true
