First create an instance of that:

  settings_val = _GlobalIDL.IdlOtnAllSettings(1, 2, 3, 4, 5, 6, 7)

(With a suitable value for the IdlErrorGen type.)


Then you need to put it in an Any. An Any has a TypeCode and a value.
To get the TypeCode, the Python mapping standard says you do this:

  tc = CORBA.TypeCode(CORBA.id(_GlobalIDL.IdlOtnAllSettings))

or being omniORB specific, you can use a static one:

  tc = _GlobalIDL._tc_IdlOtnAllSettings


Then you can make your Any:

  settings_any = CORBA.Any(tc, settings_val)


Or, if you want to be very omniORB specific, you can use a helper
function that works out the TypeCode for you:

  from omniORB.any import to_any

  settings_any = to_any(settings_val)
