When a DPA report is sent by scheduled email, there are links at the bottom such as:
"View in Database Performance Analyzer" MACHINE:8123/iwc/reportGroupDisplay.iwc?repo_id=1&id=1
"Visit the Reports page to edit this schedule." MACHINE:8123/iwc/reports.iwc
But depending where the email is viewed, MACHINE name may not be sufficient to reach the DPA server; a FQDN may be needed (such as MACHINE.domain.local).
I have not found the setting to set the hostname for such links. I have looked in Advanced settings, Email settings, Report settings, etc.
