AppLogFence
This setting is not available through the PSADMIN interface, but can be entered directly into the PSAPPSRV.CFG file.
You can use this parameter conditionally to determine whether you want to do specific logging from your application. You can implement this parameter from PeopleCode using the %AppLogFence system variable. Complete documentation for this option is in the PeopleCode Developer's Guide.
See PeopleCode Developer’s Guide: Using Application Logging.
