The database filter expects a regular expression and orbis-aton can't be
parsed as a regular expression upon trace session start.

Either escape the minus symbol resulting in:

orbis\-aton

or use % as a wildcard, e.g.:

%orbis%

This should now give you appropriate sweep trace events for the database
trace configured in the <database> section.

I see now that services tracing via the <services> section won't result
in any trace data when executing the sweep through gfix, because this
doesn't go through the services manager. And the new command-line tool
fbsvcmgr doesn't seem to support the switch for sweeping.
