The Listener requires full access to the GUI export data sets.
If you choose to default the high-level qualifier to the GUI user's user ID, you must ensure the Application Performance Analyzer Listener started task has full access to all data sets that begin with the user ID of every GUI user who will be performing export requests.
Alternatively, you can configure the Application Performance Analyzer Listener with a single high-level qualifier for all GUI export data sets by specifying a value for the DataHLQ setting in the Application Performance Analyzer Listener CONFIG BASIC statement. In this case only that high-level qualifier will require full access.
